Unable to Use TIme Machine to backup a new Western Dig external 1 TB drive. It is connected through an adaptor to my Firewire 800 using a Firewire 400 with adaptor. I cant dismount the drive to reformat it to MAC using disk format utility.
View 3 RepliesQuick question. I have an imac running leapord. I also bought an external seagate harddrive to use with time machine. It was working fine for about a month then my mac stopped recognizing the external drive. Any thoughts on what has happened or did I just end up with a faulty external drive?
View 17 Replies View RelatedI was thinking that if i bought an external MOBILE hard drive (un-powered) i could take it with me sometimes when i need it in UNI (in Lectures where there is no power source to plug drive in), but also attach it to the mac and since it is un-powered and mobile time machine will work without needing external power.

View 8 Replies View RelatedMy external hard drives simply refuses to eject/un-mount, and I've done everything I can think of to terminate any processes and/or applications that may be using the drive and preventing it from being ejected properly, but I haven't had any success. Is there some Mac-Jedi way of going about isolating what might be preventing this drive from ejecting properly? I've scoured the activity monitor but can't figure out what might be preventing the drive from ejecting?
View 6 Replies View RelatedI 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?
My Mac Pro [with 4 internal disks, 2 External Disks (Sata Raid 0), and several external FireWire disks and a Voyager disk station] has a little problem with letting externals go Since a few weeks I have a problem with unmounting my externals. After unmount, the unmounted disk will mount again immediately.No time to disconnect cables and/or power. Hinders disk management, backup, and simple disconnecting disks. It only happens with disks (FireWire 400/800/ SATA and USB alike). USB sticks work fine.

Mac Pro, Mac OS X (10.7.3)
I want to plug in my computer into my USB dock, automatically mount my external HD, have TimeMachine do its thing automatically (so far, so good), but then immediately after the backup finishes, I want the computer to automatically unmount the HD. This will allow me to close the laptop and go somewhere without having to constantly eject the HD everytime I unplug the computer.
So - what I need is a program / script / etc that will tell the computer to eject the drive as soon as TimeMachine is done backing up.
G4 Dual 867 2g OS10.5.4. I have 2 external drives (Lacie 200g USB - Western Digital 120g USB) that unmount unexpectedly, sometimes they remount.
View 5 Replies View RelatedI have a Western Digital 500gb external hard drive, with 2 partitions, 'KAINARC' and 'JUNGLEMAC', connected to my Intelmac (Tiger 10.4.11 via my firewire, i have connected via usb but the problem is still the same). I may have shut down the drive improperly to cause this situation.
KAINARC now appears on my desktop, but the partition of JUNGLEMAC does not. I go to disk utility and both partitions are visable, KAINARC is mounted but JUNGLEMAC is not. I cannot mount JUNGLEMAC.
When i try to verify and repair the partition I get the message:
Verify and Repair disk �JUNGLEMAC�
Error: The underlying task reported failure on exit
1 non HFS volume checked
1 volume could not be repaired because of an error
So I try to verify and repair the partition KAINARC but get this message:
Verify and Repair disk �KAINARC�
Repairing disk failed with error Could not unmount disk
So I have opened diskwarrior (unbelievably long time to start up and scan disks) in the hope of fixing the hard drive, but when i try to repair I get the error message 'unable to unmount KAINARC'.
I have tried other repair/recover programs but get the same message: 'Could not unmount disk KAINARC'. Im asuming that to fix the hard drive it has to be able to unmount KAINARC.
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.Â
Using disk utility one of the partitions deleted without incident when following the same protocol the second partition produced error messages.
Volume erase failedÂ
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.Â

So i bought this new 500GB external HD but whenever i tried to put my files in it from my mac it wont allow me and say, "This item could not be moved because [harddrive] cannot be modified." however if i connect it to my windows it works fine.
P.S just one stupid question, why would a 500GB HD has less capacity such as 470 or so; and sometimes 8GB USB will only have 7.5 G etc.
Will my Mac be able to use this external?

I heard that it can't and you need to by the Mac only one. Does it make a difference?
I am not very computer savvy, and new to your community here. (also I apologize if this is posted in the wrong forum. this one seemed the most logical, but I wasn't sure.)
Just bought an external harddrive for my MacBook, and my hope was to move my itunes library, photos, and a few essential documents to the external.
what is the easiest way to do this?
Also, after I have everything backed up, I was planning on restoring the computer to factory settings, and enjoy it being "like new" with all my content on harddrive. If I did this, would I still be able to seamless access all the stuff on the external, such as my itunes library? How would this work? Is it even a good idea to restore the computer?
I use my external harddrive for Time Machine on OSX. I also happened to put other files on there too. But once I run bootcamp, it seems that Windows cannot recognize harddrive. Is that normal? And is there a way for me to reach the files in Windows?

I am a rookie in Mac. I have a lot of multimedia which I store on external harddrives. Recently I have experienced my iMac freezing on me, specially when I am accessing the harddrives using my frontrow application. Eventually I got a database error when receiving mail to my Entourage. It was suggested that I repair permissions using the disk utility. This I did, however it never actually repairs anything, it just lists the stuff where the permissions differ. Anyway, straight after I 'repaired' permissions, my harddrive showed empty. No files left!!! 1TB data gone .
the way I understand it, it is a possibility that the file that lists the addresses of all the files on the disk may be the one that was wiped. I am hoping the data is still there and that someone has a nifty tool that will sniff it out for me.
I bought an Iomega Prestige 1TB external harddrive a couple months ago with it running off my Macbook Pro.
I just flew down home for spring break, leaving my Macbook Pro charger at school. However, I do have the harddrive with all my backed up files. The problem is, my PC laptop (Dell, Windows XP) does not recognizes it. When I plug in the harddrive and turn it on, the computer recognizes that there is something plugged in (it gives me the option to safely remove hardware), but there is no sign of the drive anywhere.
Is there anyway my PC can read/recognize it?
I recently bought an external harddrive and its been working properly for about 2 weeks now. however, i accidently moved my iBook G4 and my external harddrive that was connected disconnected from the Mac. the error message of "please do not remove harddrive before ejecting..." popped up and since then it has not been working properly. i've read many articles and forums and nothing seems to be suited for my situation. it is a 400GB WD portable external harddrive and it plugs/runs by the USB port. the disk utility says when i try to repair disk:
"Disk Utility stopped repairing �My Passport� because the following error was encountered:
The underlying task reported failure on exit"
and i've checked the finder preferences and everything is what it is suppose to be. am i going to have to but that diskwarrior program in order to fix this? seems like there should be an easier, less expensive, way.
I have an iomega external HD. When ever I try to transfer files from my mac internal HD I get the message "the Item could not be moved because "iomega HDD" cannot be modified." This HD works fine with windows, but is doesn't seem compatible with my mac. Any way to fix?

Ive just realised my BT homehub wireless router has a USB port, which has rather excited me as it opens up the possibility of freeing up a USB port on my MacBook, which is currently occupied by my Lacie external hardrive.
I hoped it be as simple as plugging the drive into the routers usb port and watching it pop up in finder. Alas not so. Ive plugged the drive in, but nothings showing up in OS X. What am I doing wrong?

View 1 Replies View Relatedmy mac book pro is not recognizing my WD 500 GB external hardrive. I checked and double checked to make sure the external was mac compatible before I bought : and it was. It also is not recongizing an WD external hardrive I borrowed from a co-worker. Here is what I have done and checked so far.Â
- I checked to see if the externals worked on other Mac Pros( just to double check mac compatibility)-Â they showed up on on 4 different Mac books.
- I checked to see if there was something wrong my usb ports. So I incerted my 4 GB flash drive in the USB port, and then my co-workers 4GB Flashdrive- My computer recognized both the devices.
- My computer was very full ( that is why I bought a bigger hardrive to back up my files) so I thought maybe there just wasnted even enough free space for my computer to recongize the devices. So I freed up 70GB of hardrive space on my mac book. - still nothing.
- I also checked to make sure I had the suggested software updates to run the drive, before I bought it. Â

Today i was finishing a 7min HD Video Project for my class, on a mac tower, when i got the I/O error message while exporting it. It got worse from there. Untill today i have had no problem viewing/opening/editing files from my harddrive.
Now, i cant even open the FCP project. It says final cut pro quit unexpectedly while using the kgcore plug-in When i try to watch a quicktime file, the movie will play for a few seconds, then freeze and force quit.I try to copy any file to my desktop and it says The Finder cant complete the operation because some data in(filename) cant be read or written. (Error code -36)
I ran disk utility to verify the disk, and it says that everything appeared ok.I also ran disk repair, and it also said nothing was wrong with the harddrive.I have tried to do all of these things on 4 different computers today, 3 towers and a Mac Mini.All the same results, down to the exact second and mb of the attempted transfers and watches.
