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 :: 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 :: External HDD Refusing To Mount - Volume Needs Repair

Jan 22, 2008

Last night I encountered a problem with my seagate FreeAgent external HD/D. I right-clicked on the desktop icon to eject it as per usual and once the icon had vanished I pulled out the USB cable. However, I then got a message saying that I didn't eject the device properly and might have lost data, etc. When I plugged the external drive in this morning I found that it wouldn't mount. I am in a state of panic at the moment because it is almost 150gb of data that I really did not want to lose! I read in one of the previous threads that this is a common problem amongst macs but I wasn't able to discern if this was a permanent error and if it means my drive is shafted. I ran disk utility and this is what it came up with:

Verifying volume "disk1s1"
Checking HFS Plus volume.
Invalid node structure
Invalid B-tree node size
Invalid node structure
Invalid B-tree node size
The volume needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair

I tried to repair it using disk utility but it wasn't able to do it. I am now using the demo of Data Rescue II to do a thorough scan which will take several hours but I'm wondering what options I have. Are there any other mac tools I can use? I am a total newbie when it comes to macs having only made the transition from PC to Mac several months ago and I don't know what tools I can utilize to fix this problem, if it even can be fixed.

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

Hardware :: USB HD Won't Mount / Repair

May 20, 2009

As I was copying music from my external HD to my laptop after a system restore, an error message popped up (I don't remember what it said) and the disk unmounted. This happened as files were being transferred, and I got the "disk removed without being ejected; files may be corrupted" message. I turned the drive off and turned it back on, and received this error: "The disk you inserted was not readable by this computer." I tried to run a repair in disk utility and got this: Verify and Repair disk �disk1s1� Checking HFS Plus volume. Catalog file entry not found for extent Volume check failed. Error: The underlying task reported failure on exit Disk Utility stopped repairing �disk1s1� because the following error was encountered: The underlying task reported failure on exit 1 HFS volume checked 1 volume could not be repaired because of an error I put the drive into a windows machine, which recognized the disk, but won't assign a drive letter to it, so I can't access it. It seems to me that something happened within structure of the disk as I was copying files, and something got corrupted. Simply due to the fact that a windows machine will recognize the disk as well as recognize how much space is being used on it, tells me that the information is still on the drive. I just have to discover a way to retrieve it.

Apr 15, 2009

I have a WD Terabyte drive that I have used for over a year with no problems. A couple of days ago my roommate went to use it and disconnected the drive from my computer without ejecting it first. He used it with his PC and disconnected it without "safely removing" it from his computer and now it will not mount to my desktop of been seen by PC.

Don't know what to do next.

I've not Time Machine'd in about 3 weeks. After working fine for several months, out of the blue I get this error. I think it was -61? "Get Info" said it was read only. I couldn't figure out how to make it write & read. Now, out of the blue, I can't even mount it.I'm at a loss. My iMac is on it's last legs and I'm playing with fire. I guess the first order of business is to mount the thing but it just does nothing or IDK how to force it to do this?

OS X :: External HD Won't Mount

Nov 13, 2008

I recently Installed Windowns on my MBP via boot camp and I also installed a MacDrive 5 day trial version so I could move some files from the external (1Tb WD My book pro) to the windows side. Everything went smoothly and then after my file transfers on the windows side, then in a hurry I just unplugged the firewire cable and shut the mac down. Now when I start up in OS X the drive doesn't mount. I starts up ok and then the only thing I see is a task called "fsck_hfs" eating up my CPU and memory. The drive works fine in windows with Macdrive so it's not a HD failure because all of my files are still there and usable, It's jut that Leopard can't see the darn thing. So how could I get Leopard to see the HD again without re-formating and losing all my files on it?

OS X :: How To Mount External Hdd Without Logging In

I'm running an iMac with Mac OS X 10.6.4 . It is used mainly as a database server. The database lives on an external hard drive. The problem is that Mac OS X does not mount the external drive until I log in locally. Logging in via SSH is not enough. Does anyone know how I can make OS X mount the external hard drive even if no one logs in?

OS X :: Not Able To Mount An External Drive

Jan 3, 2009

I have this sans digital USB towerraid enclosure, with one, 1TB drive in it. It's formated as NTFS. It was working just fine, but for some reason, I went to connect it to a windows machine today and it basically froze up the computer. so i tried a few things, and it was still freezing the computer.So i connect it to my macbook pro where it normally is, and when it tries to mount the device i get an error from NTFS-3G. I added an attachment of the error it gives. I tried inserting the command line it suggests in terminal , but it didn't really do anything. I'm not really familiar with terminal or how to use it fully.

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 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.

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.

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).

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.

Info:
MacBook Pro, Mac OS X (10.7.3)
