I disconnected a working external 750 Gig G-Drive. When I reconnected it, it won't mount. I have restarted the computer. I have disconnected & re-connected the drive. Still no luck. What should I do?
Info:
iMac, Mac OS X (10.7.4)
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?
View 1 Replies View RelatedI'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?

I just purchased a new iMac, System 10.7.4. When I tried plugging in my old WD external with a newly purchased Firewire cable (couldn't attach with the cable that came with the drive originally), the drive didn't show up on my desktop. I tried shutting down and restarting, thinking that would help, but it did not.  I then removed it and placed it back on my G5 Tower and it works fine. I am running system 10.5.8 on my old mac, just as an FYI. I need this drive as my time machine backup is on it.

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?
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.
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?
View 16 Replies View Relatedi bought a ibook G4 off of a friend and knowning it needed some repairs it needed a new Harddrive. He had a 100Gig Seagate replaced in it before me and I tried a new 60Gig when I got it.either one of us couldnt boot either HD, we can not find the new Internal HD with the Mac. I can boot off a External HD holding down ALT. And i already tried clearing the P-ram many times.
Also when i go to load a 10.3 OSX disk it loads and either gives me a red circle X or like sorta artfacts and shifts the apple screen to the side of the page. Ive spent hours trying to fix this and have no luck. do i need a 10.4 or 10.5 disk? i did add 256MB ram to it so heres the specs. I have no clue what to do.

Since upgrading to Mac OS X 10.7.4 I am unable to mount any of my G-Tech Raid hard drives.
Info:

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.
View 3 Replies View RelatedI'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.
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.
Just bought the WD Elements external Hard drive, plugged it in... and it won't mount on my G4!

I've got an external 500gb Seagate drive with 2 journalised partitions.....one for my time machine backups and the other for holding audio samples for my drum machines and such. All of a sudden today the audio partition won't mount but the time machine partition still works fine. I go into disk utility and it shows ther but just says unable to mount when I try to mount it. It suggests first aid so I verify and repair numerous times and it says everything is ok. I can boot up Ubuntu in VMware andboth partitions are visible and all the files are there....everything is just as it should be. I was using 10.5.7 and just upgraded to 10.5.8 tonight and nothing changed.
View 4 Replies View RelatedHello everyone. I've been using an external Western Digital My Studio (500GB) drive for the last year or so with a Core2Duo Macbook Pro, and have had no problems until this morning. The drive is used primarily for Time Machine backups, but I also have some photographs stored as well.
This morning, just after I'd begun copying some of these files to another external drive, the WD drive went down, and now will not mount/showup in Finder. It DOES show up in Disk Utility, though with the Time Machine volume grayed out. I get a "could not mount" error when I click on the "mount" icon, and nothing else I try (rebooting, unplugging drive power supply, etc). has worked. I'm trying to avoid the erase-and-reformat option, because I'd lose some potentially valuable images.

I have a LaCie 320 GB external hdd (USB 2.0) that worked perfectly until last night. Now it won't mount when I connect it to my computer, nor can I see it in Disk Utility. Disk Warrior can't see it either. I tried connecting it to my roommate's MBP with no luck.
It spins up just fine and doesn't make any clicking noises or anything like that, so I feel like there might just be some hope yet; I'm thinking it might just be a faulty USB cable or something, but I don't have a spare one to try it with.
Alright, so My ipod is formatted for windows when formatted in this you can only copy chunks of 4 gig things using it as an external. but if you change the formatt of it to take all sizes, then it's not compatible with mac and pc. =/ i had it originally formatted for pc because i just recently got a mac book pro and it's my primary computer. well on to the hard drive trouble that is related i'm borrowing my friends external to get a 8 gig file from my pc to my mac. it's formatted in fat32(windows and mac read) but that format only allows for a 4 gig max to be put on it at one time. so i guess i'm outta luck there, i've looked at JR split but who knows it that will work. My main q is, i'm going to be getting my own personal external soon and i want to know whats the best way to format it that it will mount on my pc and my mac and allow me to copy more that 4 gigs of stuff on it at a time.
View 1 Replies View RelatedAfter a lifetime of owning PC's I finally purchased a MacBook Pro running OS X. I installed Parallels Desktop 5, Windows XP, and several Windows apps to have dual functionality. Now I need to write to my NTFS ext. hard drive where I backup everything. It has 800gb of space left, so it would be a shame to get a new one just b/c I have a Mac now. I first installed MacFuse and then NTFS-3G. Now when I reboot, the ext. HD won't mount at all. What have I done wrong?

I just installed a new internal hard drive into my macbook as my old one was failing. Before doing this I backed up all of my information through Time Machine onto a Seagate FreeAgent external hard drive. I've been using this external hard drive for the past two years and I've never had any problems with my macbook mounting it. Once I had all of my personal information backed up I took out the external hard drive and then proceeded to take out my old internal hard drive and installed the new one. I installed the Mac operating system and the Macbook started up just fine but when it came time to reload all of my personal setting using Time Machine my macbook didn't recognize that there was an external drive plugged in. I know it isn't the external drive as it mounts just fine on other laptops. how I can get my macbook to mount the drive so that I can transfer all of my information onto this new internal drive?Â

View 14 Replies View RelatedI'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. I had WD send me a new drive, but now I do not know how to transfer the info from the old drive. Its not a dead drive- its obviously turned on and connected, but I can't mount it to my desktop. Any advice??
I have a iBook G4 (if that matters).
