Hardware :: Unable To Mount WD Drive?

Oct 22, 2009

I'm trying to access some files for a client on a Western Digital external firewire/USB drive on my MacBook Pro. The drive will not mount in Finder.

The upper level drive shows up in Disk Utility, but the partition of the disk I would like to mount (the only partition on the drive) is greyed out. I know that it's formatted for a Mac and has been accessed recently.

In Disk Utility, when trying to mount or eject, the an error comes up saying to use first aid. Verify and Repair Disk don't change anything though.

OS X :: Unable To Mount Lacie 500 GB Hard Drive?

Jul 26, 2009

I am new to this forum and hoping for some advice with this hard drive issue.

I opened a brand new Lacie 500 GB Hard Drive. It is connected to my macbook via usb. I selected it as my hard drive destination in Time Machine and ran the backup option.

The hard drive did mount. About 5 minutes in the backup option failed - a time machine error: time machine backup failed.

I ejected the drive and unplugged it/turned it off and rebooted my laptop. Now the hard drive does not mount on my desktop however will show in disk utility. It lists with the Lacie name and another subdivision under the name.

When I try disk repair, erase or partition..I always get the same message: resource busy. After the error, the hard drive subdivision disappears leaving only one name on the list in disk utility. (It does not have the name underneath it).

I apologize for my semi technical description. I am new to mac and appreciate any advice on how to fix this issue. All I want to do is backup my laptop using the new hard drive with time machine.

Desktops :: External Hard Drive Unable To Mount

Jan 20, 2010

Without warning my iMac [OS X Snow Leopard] popped up an alert saying that I should eject a drive before disconnecting it. I had done nothing to generate this error message. I clicked ok to close it and noticed my 4 month old, external 8T Mercury Elite-AL Pro Qx2 was no longer visible in my drive directory. I also noticed this external unit was making a looped grinding noise as if it was trying to write without success. I figured one of the drives failed and took it to the mac doctor. Other than a few directory errors, everything appeared to be fine, so I paid the service fee, brought it home and plugged it in only to find the same prob - obviously it's something with my iMac. Before I go spending more service fees, I wondered if anyone here could point me toward a method of discovering what might be wrong. I ran disk utility [verify and permissions] and fixed some directory errors, but don't know how to look further. iMac was home networked with a PC [Windows] and a laptop [Windows]. I did notice something wacky with the PC, but its very old and I expect it to die any day. I was running the network through the PC, so I direct connected the iMac to the router and modem but no change: still cannot see the external drives. What other info do you need to make an educated guess for me?

I'm new to this forum, but need help with my external harddrives (WD Pasport 250GB). I can find it in my disk utility, but not on my desktop.

Any advice??

I have a iBook G4 (if that matters).

OS X :: Unable To Mount External Drive / Repair Disk Permissions?

May 20, 2009

I'm having a series of problems. First some intermittent audio problems with Garageband, then, then some external drives won't mount, and now I can't sync to my disk from the iMac. I've run Disk Utitilies a few times and when I do Verify Disk Permissions, it finds a list of things to fix, I then hit Repair Disk Permissions and it fixes them, and then hit Verify Disk, and it say the disk appears ok. When I do Verify Disk Permissions again though, it finds another long list of things to fix. Is this serious? What should my next step be? Should I reinstall the entire system?

Hardware :: Unable To Mount Hard Drive In OSX / Data Recovery Software?

Aug 5, 2010

Recently, I was hired by a client to recover the data on a new macbook pro. They said one day the computer just wouldn't start, so they brought it to the Apple store, where they switched out the hard drive. They got to keep the old drive, which I attempted to recover using VirtualLab and R-Studio data recovery programs and a USB hard drive case. Both programs did the same thing: they scanned, and kept finding errors and never even got through 1% of the disk! R-Studio even scanned for almost 24 hours and nothing came up from the partition we needed to recover! Disk utility was the first thing I tried, and it appeared to have scanned the entire drive (this was about 3 weeks prior to trying the other programs)and found a lot of errors, but was not able to recover or repair the drive.

Also, the hard drive kept making a pulsating, repeating sound while it was being scanned that sounded like it was trying to read the disk, almost a scraping sound but not quite. The drive did spin up and was recognized by the recovery programs, but it did not mount in OS X.

I was just wondering if anyone here has had a similar problem, or knows of a better program and/or a good, trustworthy advanced data recovery service she can hire to recover her important data.

Hardware :: Recover Data From Dead Lacie Hard Drive / Unable To Mount Hard Drive

Sep 6, 2009

Today I went to plug in my Lacie 250 GB USB external hard drive into my 13 in. MacBook to get a shirt template for a design I am making. I discovered that the hard drive just would not mount and show on the desktop, and I remembered that this happened a few days before, but all I did was unplug it and plug it back in, and it worked... except that today, that didn't work at all. I tried the other USB port, and the hard drive showed up on the desktop for about a second, and then disappeared. I kept on replugging it back into both USB ports, but nothing happened.

Then I tried to see if it would work on the PC beside me, and it was recognized as an external device; however, a message came up telling me the drive was malfunctioning. I am guessing this is from ejecting it incorrectly (because I am in a hurry to head to my next classes...I use this laptop at school), but I have incorrectly disconnected it before in the past and this problem never happened to me before.

Every single project I have ever created for my design career is on that hard drive, and all I want now is to get my files back. All I need it to do is show up on the desktop for just the right amount of time for me to copy my files onto my computer.

I read online to put it into the freezer for a while and it should mount, but that didn't work. I tried using Disk Warrior, Data Rescue 3, and Tech Tool Deluxe, but the hard drive did not show up on any of those apps.I tried plugging the hard drive into an iMac as well, but it did not show up either.

Mac Pro :: Hard Drive Will Not Mount After Optical Drive Upgrade?

Feb 23, 2012

I recently performed an optical drive install. Had to remove the hard drive bays (I use three hard drives - Luckily, 2 run OSX).  I carefully removed all three drive bays and the empty bay. When I inserted the drives into the computer I had changed the position, swapping one OSX drive with a different one and reversing the drive bays. On restart, the computer started on the drive I had not selected for startup and I received an error message stating the other drive could not mount and it gave three options (Initialize - Ignore and Eject).  

I can see the drive in Disk Utility and repair the permissions (it's also located in the System Profile).  

I tried a few things I read in the community using various Terminal commands but was unsuccessful.   

(Let me point out that I recently switched from a PPC G5 to MacPro and swapped the drives from PPC into MacPro and all has been fine until I removed changed their positions in the bays)

OS X :: Unable To Mount Backup Disk Image?

Jan 6, 2009

for the past month or so my automated backups with time machine/time capsule have not been working. Every so often the following error message pops up:

"the backup disk image could not be mounted"

in troubleshooting, i have tried to mount the sparsebundle image directly but without success. from reading around a bit i can see that others have had this problem, and that one solution is to delete the sparsebundles and start again.

but that of course means losing all my archived backups, which i would rather avoid.

MacBook Pro :: Unable To Mount Time Machine?

Dec 10, 2009

Not only did my MBP hard drive just stop working, but I needed to get the files off of my time machine backup on my other mac. My other mac was running very slow so I upgraded it to SL.

After I upgraded, I plugged my 1TB WD hard drive into it and it does not recognize the hard drive. It worked find before I did the upgrade.

So I borrowed my neighbors mac and plugged my time machine into her laptop running straight leapord and it also failed to mount.

It is almost like plugging it into the computer with SL unmounted the disk inside the casing. It happened to both of my time machine backup drives..

If I can not get these drives to work, I have lost 2 years worth of data that I backed up in two places.

OS X :: Unable To Mount LaCie Little Disk 320gb?

Mar 15, 2010

I bought the LaCie Little Disk 320gb about a year ago and it has been working fine till recently..

The problem that I have is that the laptop that I use (Powerbook G4) doesn't recognize the HD anymore..

I have tried all cables (both firewire's and the usb) but nothing works..

I did try it on multiple computers (macbook's / imacs and even some windows computers) not one did recognize it.

(well the windows computer I used it on did recognize it but it cant open it and Windows Explorer stops working till you pull out the HD).

The only think I can think of is that I pulled out the HD to many times without safely removing it first..

I got a lot of data on the HD and I'd (offcourse) like to get it back,

I haven't been to the store yet (going somewhere this week).

Software :: External Hdd Unable To Mount - How To Repair

Mar 20, 2009

external harddrive (Seagate brand). I've bought DiskWarrior (the latest

version) and rebooted my mac to run the program. It recognized the

drive, but said it was not supported.

(i used to use it with my pc, but it did,once, run on the mac- until i yanked the cord out!)

Is there an issue with formatting that i need to get around so that my mac can read the drive to repair?

OS X V10.7 Lion :: Unable To Mount Disk Image

Feb 28, 2012

Yesterday I downloaded and installed Lion. After a while I tried to open one of the disk images that I have stored on the harddrive, which worked to mount prior to installing Lion. While attempting to open it, the process fails and gives the error "no mountable filesystems". I have searched for the error on the internet, and there does not seem to excist a solution to it. However, all the people with the same error, whcih did not have a solution, did not seem to have a similiar problems. Their problem lied with not being able to access disk images downloaded from the internet, while my disk image already excised on the hard drive before installing lion.

Many of the files and documents on the disk image are irreplaceable to me. I can not stress how important it is for me to recover them. If I am not able to do so, it will result in a massive economic loss.

I purchased a WD My Book Home edition. Followed instructions and correctly formatted for Mac.

Firstly *(and it now seems a fluke) on power up it switched on and appeared but ever since then, light does come on when I put the main power on but it wont show/mount on the desktop, unless I switch off the drive and back on again and even then it may not power up unless I unplug the power cable.

MacBook Pro :: Unable To Mount Hd Automatically / System Asks For Permissions

Feb 15, 2011

I have a Seagate Free Agent external USB hard disk (250 GB) which I had reformatted to FAT32. This draws power from the USB port and seems to work perfectly on my Linux (Fedora Core 8) and Windows (XP) boxes. On the Mac, when it is plugged in, it asks me whether it should Initialize, Ignore or Eject. I choose "Ignore" and then go on to mount it from the terminal using the commands sudo mkdir /Volume/FA sudo mount /dev/disk2s1 /Volume/FA. The device name has to be found out first using Disk Utility. After it is mounted, I can read, write, delete etc. without any problem.

Question: Why does it not mount this disk automatically? Even when it is mounted why does it not put a disk icon on my Desktop? I have no issues with smaller FAT32 pen drives which show up on my Desktop a few seconds after I plug them in.

MacBookPro

Windows On Mac :: Unable To Mount Partition - Grayed Out In Disk Utility

Dec 26, 2010

I can boot into bootcamp with no problems. I have been wanting to be able to open the bootcamp in Parallels. Here is the issue:

1. The partition 'disk0s3' is greyed out in Disk Utility. It is not mounted. Mounting does nothing.

2. For reference, the Windows 7 is formatted as NTFS. It is a Windows 7 64-bit install

3. Verify disk does the following:
Verifying volume "disk0s3" ** /dev/disk0s3
Invalid BS_jmpBoot in boot block: efbbbf
Error: This disk needs to be repaired. Click Repair Disk.

4. repairing does the following:
Verify and Repair volume "disk0s3" ** /dev/disk0s3
Invalid BS_jmpBoot in boot block: efbbbf
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can"t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

I have stuff on the Windows partition that I don't want deleted. I'm really stuck on this -obviously, I can just continue to boot into bootcamp, I just would rather open it from Parallels. I'm not sure what or if I made some mistake in setting up Bootcamp, I thought I followed the directions to that. I do know I formatted the partition as NTFS during the install - as I think Windows 7 requires it. I have tried installing NTFS-3G - it is installed, but didn't do any good when trying to mount the drive.

Jan 10, 2009

i bought a ibook G4 off of a friend and knowning it needed some repairs it needed a new Harddrive.

OS X V10.5 Leopard :: Disk Image .DMG Unable To Mount / Attach - Not Recognized?

Jul 3, 2012

After a fatal mac crash (PPC 10.5) i had no option but to reinstall the OS (10.5), i obviously didnt reformat the drive in the hope that i would be able to recover some if not all of my data. Using various tools i was happily able to recover most of my data successfully, including 3 AES encrypted Disk images of around 30GB in size each.

I didn't hold out much hope for actually recovering the data inside the dmgs, although after some fiddling i was able to recover 2 of them fully after receiving the no mountable file system error, i dont know how i done it but nonetheless i dont appear to have lost any data from those two dmgs whatsoever. Now the third dmg (also about 30GB in size) never gave me the no mountable file system error and instead returns the error: unable to mount: not recognized. Im pretty sure that my data is still there somewhere due to the sheer size of the recovered file, tied with the fact of the success of the recovery of the other 2 disk images. I have read every post i could find on this site and have trawled the web tirelessly looking for a solution to this, but have yet to find anything that even comes close - the closest i have found was a post on this forum where it would appear an apple engineer was able to recover most of the data using some sort of magic.

I am not in a position to pay for professional data recovery and besides i would love to see a solution to this problem appear somewhere on the web. I have tried the usual, rebuilding permissions, mounting on another machine (imac G5), resizing with disk util, repairing with disk warrior, converting to ISO - all which return the same error - not recognized! I have tried every terminal command i have found on the web, although decyphering some of the information is a little out of my remit and my knowledge of HEX is limited. I haven't yet tried Toast, basically because i dont have a copy, but it would be my guess that this would return a similar result. Incidentally when i recovered the original data, there were some small (what appeared to be dmgs) files around only maybe a few Kb each with part of the file names of the original files, i'm guessing these maybe the headers or something like that? although i didn't have to do anything with them to get the other 2 disk images working again.

Hardware :: Unable To Mount Hard Drives / Cannot Recover Lost Data

Jan 6, 2010

I have a dead La Cie Big disk terabyte external drive. It won't mount and it isn't recoverable the way it is. So I looked inside, it's 2 x 500 gig Seagate drives. So, I took the 2 drives out and installed one of them in a Mac Pro to see if it would mount on it's own. I figured probably not, since there were two drives mounted in this La Cie external case, they must have been RAID-ed together. I don't really know much about RAID, obviously.

Disk utility saw the disk, but it wouldn't mount and gave the unreadable message. Tried to disk utility it, and it gave file system errors, not surprised. It looks like you can't separate them, the RAID must split the files onto the two disks.

Is there any point to trying the utility Data Recovery on it? Or should I just tell my boss the only way to get the data back is to send it out to a data recovery place? I don't want to try and reformat them if there is still any possible way to get the data off them. I think the drives are fine and would work as a terabyte drive in the Fantom case if reformatted, but then we lose all these important projects.We seem to have the worst luck with external hard drives.

The odd thing is that I have another dead terabyte drive, a Fantom drive in which one of the 500 gig drives started clicking. I took both 500 gig WD drives out of the Fantom case and installed the two Seagate 500s from the dead La Cie case. It shows up in Disk Utility as an unformatted 1T drive. I was hoping it might just reconstitute itself in another case, but no go. If worse comes to worse, I will reformat it and it will probably be useable.

OS X :: USB Pen Drive Won't Mount

Nov 17, 2010

I tried searching for a solution for this and can't find any. I've seen one other threat in here about similar problems but the variables in my case are different. Here's the thing, a friend of mine lent me her usb pen-drive. She uses it on a pc mostly at work. When she gave it to me she forgot to copy some files i needed so she plugged it into her macbook pro (one of the new ones from this year, intel, snow leopard and stuff), copied the files i needed on it and i took it home. I have an intel imac, bought on april 2009. I plugged the usb pen-drive on my keyboard usb port and nothing happened. So i took it out, plugged it in again and nada. I did it a 3rd time and this time it showed me a message saying that this pen-drive needed more power and i had to try plugging it into a different usb port. So i plugged it in the back of my imac and nothing happened, not even the "insufficient power" message. It doesn't mount, won't show up in the desktop nor in the sidebar of a finder window.

I checked the disk utility and the pen-drive shows up there. I see the "main" pen-drive and it's "partition" (i dunno how to call it... mmm... you know, like you're seeing the "parent" drive and its "son" drive but they're "one and the same") and i can see its tech info and i noticed it's formatted NTFS. Since it worked just fine on my friend's macbook pro, i can't figure out why isn't it working in my imac. I know macs can't write NTFS, only read (mine doesn't at least) but hers wrote info in the pen-drive no prob. Another thing i noticed is that the "son" drive is grayed out. I can see its tech info but it's grayed out. Verifying the drive simply shows a message saying "Verify volume failed: Invalid request.".

So, i have no clue as to what's going on. I could give it back and ask my friend to format it as journal or whatever it's called to be mac os compatible and copy the info back again, but i don't know if that'd be a solution until i'm able to try it in a few days. Can't ask her to format it fat32 since the file i need is larger than 4gb, so yeah. Any clues as to what could be the problem? I even tried unplugging any usb peripherals and no dice.
