I want to carbon copy my bootable external drive to my main internal bootable hard drive so I tried to use Disk Utility to erase it but it will indicate that it failed and can't unmount. When I tried to manually unmount by dragging it to the trash it indicated that it is in use. I can't understand why it's in use since I booted from the external drive which I wanted to the copy to the internal drive.

I replaced a 1 TB external drive partiotioned in 2 with a 3 TB extrnal drive run/store my corbon copy cloner back up and time machine.
The 3 TB drive was successfully partitioned through the disk utility and both back ups are installed and the initial back up is complete.
My question is about the 1 TB drive. I want to completely erase all data from the drive in order to use it for a different use.
Using disk utility one of the partitions deleted without incident when following the same protocol the second partition produced error messages.
Volume erase failed
Volume Erase failed with the error:
Couldn’t unmount disk.
If I try to eject the disk
It says it will not eject becaus e a program may be using it...
The only program that utilized this partition is Carbon Copy Cloner which is not being utilized on the new 3TB drive.
I do not see where there is a option to have more than on disk chosen for this purpose so am unsure why the disk utility is seeing the old partion as still in use.
I have a MacBook Pro running OSx 10.9.4 and have been successfully using Time Machine with a WD My Passport External Hard Drive for a while. Now (after 10 days with a successful back-up), the computer will not back-up. I have gone into disk utility and tried to erase, partition, and/or repair the disk, but repeatedly get error messages - it can't erase the disk, re-partition the disk or unmount the disk.

So so annoyed right now. Today my 12" G4 powerbook started to become slow, lots of spinning wheel, delayed menus etc. I checked file permissions, rebooted and it just kept on getting slower. Eventually it wouldn't get past the white apple screen.
I booted off the Tiger DVD and ran disk utility to fix and repair permissions again. It wouldn't let me repair the disk as I kept getting this error:
'Repair volume failed with error could not unmount disk'
I had to reboot again, and eventually my hard disk no longer appears in Disk Utility. I tried to boot into safe mode and get this:
'"I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus"
So now I pretty much can't do anything with it. Failed Hard Drive?
I've just transferred my data to a new computer and now need to erase the hard drive on my old one.. I've tried Disk Utility, increased the security, and tried 'erase' but I keep getting an error message "couldn't unmount disk". I've gone into Partitions and tried deleting the HD there as well but I get the same message. I just want to get the computer securely wiped and would like to keep Lion as the operating system.

I've been having problems booting into my OSX partition. At the time it started I wasn't using my Macbook Pro (Late 2009) very often so whenever I needed I just booted up into my BOOTCAMP partition. Anyways, I decided to finally stop being lazy and do a clean install. There's nothing on either partition of the same hard drive that I want. I put together a bootable USB drive and boot from it. From here I go to the Disk Utility and try to erase the entire drive. It gives me this error: URL....
Now, that's not a screenshot from my mac but its the exact same error. Anyways, I've tried to find something on point but I just can't. Some posts have stated that the hard drive is broken, but if that's the case why can I start up the BOOTCAMP partition of the exact same drive flawlessly? I can even manipulate files on the OSX partition from Windows 7.

I have a 2.5" hard drive connected via USB to my MacBook that keeps unmounting itself. This happens under some (what seems to be) undetermined amount of time, the drive will all of a sudden unmount itself and disappear from the Finder, Disk Utility, et al.
Is there some fix, setting or work around for this? Very annoying. If not, is there a way to re-mount the hard drive without turning it off then on or reconnecting the USB cable?

It appears as if some files withing the disk are still running but I have no way of quitting them-knowingly. I can specify more if this seems to vague.

Notes. Failed HDD ASD Test. A new hard drive was installed in September of 2011 after the previous hard drive failed. Having worked well until now the system seems to give the same problems as it had previously. I am wondering if this is a compatibility issue as others have pointed out.
I have been told by the technician my only option is to replace the entire hard drive again for the second time with a new one. However to my understanding a ASD test is very specific and this my not be necessary? Further I am attempting a final backup just in case. I don't have to take it in where I could just back it up myself without the system shutting down.

I am going to be selling my trusty 12" PowerBook G4 to a friend soon, and putting the money I get from that towards a last revision 15" PowerBook G4. After I transfer my data from the 12" to the 15", I want to completely and securely erase my hard drive. The thing is, I don't know how to do this! I've never formatted/erased a hard drive before.
View 14 Replies View RelatedI am using a macbook with an Intel Core 2 Duo (about two years old) and I am running leopard (10.5.8).
I have been using a Western Digital 250GB External Hard Drive with a firewire connection to utilize Time Machine for the past 6 months. All was going reasonably well until recently. (It would occasionally get stuck backing up and I would have to restart my computer and then backup again, but otherwise ok)
Last week I turned my computer on and it didn't recognize the drive. It gave me the "Initialize" "Ignore" option screen. I tried everything before I tried erasing it, but eventually I decided to lose all of that backed up data and just erase the drive and start from scratch. (I backed up on a different drive prior to trying this.)
Anyway, now when I go into Disk Utility and click on the Erase tab and then try to erase the drive (doesn't matter which erase option I choose) it says it is unable to erase the drive. If it is plugged in w/the Firewire cable then it gives me an "Invalid Argument" error. If it is plugged in with the USB cable, it gives me a input/output failure error.
Does anyone know if I can fix this drive? Any ideas as to what may have caused the problem in the 1st place. Months ago I accidently unplugged the drive without ejecting, but it worked for for a long time after that.
I'm in a bind. I want to sell my MacBook Pro, but my dad threw away the installation DVDs that would allow me to erase the hard drive. What's the best option here? I was thinking that I could purchase the upgrade version of Leopard on Ebay since it's cheaper than the full version of snow leopard... but would that allow me to erase the hard drive?

Macbook OS X 10.5.8 and a WD 10EAVS 1TB External Hard Drive. That's all. I was given this by a fellow student on campus who was graduating. So I want to use this to store my iTunes Library (my Macbook's hard drive ran out of space). Here's what I do:
- Macbook is turned on and running
- I plug the external hard drive into a working outlet --> Hard drive turns on
- I plug the external hard drive into the mac using a USB connection --> Disk Insertion Error message: the disk you insterted was not readable by this computer
- It is not readable so I open it in Disk Utility (the hard drive is listed/recognized)
- I attempt to erase and/or partition the hard drive in order to format it in Mac OS Extended OR Mac OS Extended (Journaled), but I get one of these two messages: "Disk Erase failed with the error: File system formatter failed." OR "Disk Erase failed with the error: The underlying task reported failure on exit."
I attempted to look up what these mean or how to fix the problem but nothing is really working. I was able to format the hardware line to MS-DOS (FAT) and the sub-line as Mac OS Extended (Journaled) but I don't even know if that's right or not.Basically, I need my computer to recognize this hard drive whenever I plug it in and to run smoothly as "extra space" to store my music on.I haven't had A LOT of experience with external hard drives but enough to get things done. But this problem is a killer.

After waiting in a non iphone line today at the apple store to pick up my Black Macbook that hard drive failed. Well I got there and I realized I still had tiger on it. So I get in the car start it up and after set up I got Leopard on it for free! lol I was like this is nuts. So applecare covered my repair and I didn't have apple care and they said with the situation I had they would let it go. So I basically saved 350 dollars! What a day!
View 9 Replies View RelatedThe first day I got my MBP two years ago, it fell off the coffee table and got a small dent in the left side. I thought it was a cosmetic problem, and didn't think much about it. Three months ago, when my laptop was in for repair because the screen cracked due to a manufacturing defect, I told the Apple employee that when my laptop was in for repair, and they inspected the dent and found that it could cause problems for me in the future, to repair it and quote me the price to fix it. I assumed that the price to fix that dent and prevent future problems would be a lot cheaper than fixing whatever may break from it in the future. I got my laptop back, with a note saying that the dent was a cosmetic problem and consequently they didn't feel the need to fix it. So that was all good.
Until my hard drive crashes. So I take it to the Genius Bar, and they send it in for repair. I get a call today saying that the dent was the cause of the hard drive failure, and that the failure wasn't covered under warranty because of accidental damage. They also quoted me $1240 to fix it. I wanted to argue that since they didn't fix the dent and charge me for that three months ago because it was determined to be a cosmetic problem, that it should be up to them to fix the hard drive, since I tried to take the preventative measure awhile ago and they said there was no problem. Do I have a case here, or should I just have them send the laptop back and try to get it fixed cheaper?
