Cannon unmount an external drive that was a Time Machine backup

I have a mac mini attached to an external Raid enclosure with two drive inside. One of those drive is acting funny and I would like to try to erase the drive, and reform and repartition it.
I removed the drive from the enclosure and have installed that drive in a USB enclosure. I can see the drive in Disk Utility but it cannot repair the drive. Eventually Disk Utility indicates it cannot repair the drive. I get this:
Verify and Repair volume “Time Machine 2TB”Repairing file system.File system check exit code is 8.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 tried removing the partition and that ran for an hour with progress.
I also tried forcing the drive to unmount from the command line. First I got the list of drives:
Proton:Desktop wayne$ diskutil list

The drive I am interested in is disk2 ("Apple_HFS Time Machine 2TB")
when I try to unmount this way it also fails:
Proton:Desktop wayne$ diskutil eraseDisk HFS+ "Test" /dev/disk2
Started erase on disk2
Unmounting disk
the slahes look like a barber shop progress bar on the console.
Anyone have any ideas how to erase the drive?

The TIme Machine volume does not have that checkbox.
I think the issue is with your Finder...
Go to Finder "Go" menu hold the option key and choose Library. Then go to Preferences trash these files:
com.apple.finder.plist
com.apple.sidebarlists.plist
Then, restart, or log out and in again.
(You will have to reset a few finder prefs the way you like them.)

Those look alot like file names and not infection names. I don't find any reference to anything like that on Norton or VirusTotal. Since you said these were Trojans, I would expect to see "Trojan" as part of the infection name.
".jar" files are executable Java applets. The random alpha-numerics would seem to indicate a cache file, likely from a browser with Java enabled. And we all know what ".zip" means.
Worst case is that you had Java enabled in a browser and were infected by one of the late variants of the Flashback Trojan over a year ago or one of a couple of other attacks using the same vulnerability but targetted against a small number of political sympathizers. Much more probable is that thes were Windows only Trojans. Hopefully you have a fully up-to-date OS X, including Java, and have disabled Java in all your browsers by now.

External usb disc used for Time Machine backup disconnects when Mac has been into sleep mode

I use a 1Tb External usb disc used for Time Machine backup which works fine, but when the Mac goes into sleep mode & powers back on I get a message stating that you should always eject the Drive before removing.
Any suggestions on how to get around this problem would be welcome

Look at the root of your hard drive for a folder called Backups.backupdb.
Or, a sparse bundle disk image for one of mobile computers that might have tried to back up to your Mac.
If you have those, remove them and try again.

Do I need startup discs to upgrade hardware on MacBook Pro or can I restore the hard drive from from a Time Machine backup?

do I need startup discs to upgrade hardware on MacBook Pro or can I restore the hard drive from from a Time Machine backup?

Ok, well go and grab a small 2.5" hard drive enclosure so you can put the new drive in & temporarily use it like an external hard drive.
Download Carbon Copy Cloner or Super Duper and make a bootable clone of your current HDD on the new HDD.
Once that's done you can test the clone by booting from it. To do this hold Optioni while booting to select the external (new) drive. If everything looks ok, you can go ahead and swap over the HDD's.
So much easier.

HT3275 Verbatim drive I use for Time Machine backups got messed-up. I erased it. It does now perform its regular back-ups. HOWEVER, I can't "Enter TM."

I am running OS 10.6.8. The external Verbatim drive I use for Time Machine backups got messed-up, so I erased it & chose it as my back-up disc for TM. It does perform its regular back-ups. HOWEVER, when I try to "Enter TM" nothing happens?

I read some hints about this issue from similar queries, including "Restart your computer". That did the trick!

I just installed a larger hard drive, and used my Time Machine Backup to transfer my info back to the new hard drive. When I open Iphoto, my thumnails are there, but they aren't linked back to the actual photos.I see the photos in my HD. What should I do

I just installed a larger hard drive, and used my Time Machine Backup to transfer my files back to the new hard drive. When I open Iphoto, my thumbnails are there, but they aren't linked back to the actual photos. I see the original photo files in my HD. Is there a way to link the Iphoto thumbnails back to the original files?

Use the Firewire cable and t boot the old Mac's hard drive to the new Mac's desktop and transfer your entire iPhoto folder.
Use Disk Utiliy to erase'format HFS+ Journaled your TimeMachine drive and use the free Carbon Copy Cloner and clone your new boot drive to the external, it's hold option bootable.

Cannot install Yosemite as hard drive is used for Time Machine Backup, How Do I Change This?

I have a 2010 MacBook Pro and when I attempted to install Yosemite the MacBook Pro Drive is greyed out and a message appears that read,"drive is used for Time Machine Backup." How do I change this to install Yosemite?
Thanks,
Scott

Well, if you don't want to use that drive for Time Machine anymore, then you should format it using Disk Utility. Then you can install Yosemite on it.
You should, of course, have another full backup somewhere. I really can't state this strongly enough: You should have a full and complete and up to date backup of all your data before you upgrade to OS X Yosemite.

Primary Hard Drive Recognized as a Time Machine Backup Drive

Hi,
I am having some trouble installing the latest OSX Mavericks due to the installation application erroneously recognizing my primary hard drive being used for Time Machine backups. I have removed my backup drive from Time Machine, removed the backup drive from my laptop altogether, turned off Time Machine in system preferences and restarted numerous times in an attempt to get the OSX Mavericks installer to recognize my primary hard drive.
Is anyone else having this problem? Is there something I am missing?
Thanks!

As Time Machine deletes files when the drive gets too full (deletes the oldest backup to make room for a new backup), it would depend on which backup your movies are and when they'd get deleted. Once you delete them on your hard drive, they won't be in the newest TM backups either. I'd suggest you copy them to another hard drive or a flash drive/USB stick - of course they'd need to be large enough.

I want to include an external Photo drive in my current Time Machine backup. How?

I just set up my Time Machine last night. I have two additional external hard drives attached to my iMac, one with photos, one with music. I wanted those two external hard drives to be included in my Time Machine backup, but apparently I did something wrong in setting up Time Machine because it appears they have been excluded from the backup process.
I see them listed in the exclude list, but I see no way to add them to Time Machine backup. The whole reason I wanted to get this backup set up was to make sure my photos and music were coppied to the backup. Is there a way to add these two external hard drives to my Time Machine backup now that it has been set up? If not, is there a way to start over and re-setup the Time Machine so I can include them?
It seems like it shouldn't be so complicated. What am I missing?
Thank you for your responses.

You remove the drives from the exclude list..
Use the + to add things to the exclude list..
Highlight the item and use the - to remove it from the exclude list.

Which format for external hard drive to use with time machine backup and connect to windows laptop?

Hi! I have an external hard drive on which I have transferred my iTunes library (just mine - not others). I have also a folder containing just films (some but not all of which are in iTunes too) Everything has been working just fine until yesterday I noticed that Time Machine was not including the external hard drive in back up as it wasn't formatted. So I have moved everything back to the Mac hard drive and and ready to format the external hard drive - but understand that if I do the contents cannot be opened from a windows laptop ... is that right? Is there are format I could choose that would allow Time Machine to back up and allow Windows to open as well (the idea being that I take the external hard drive with me on holidays etc!!) Many thanks for any advice.

ok - I understand. I have managed so far to format the drive (on windows) to exFAT file system - which apparently works with both Windows and Mac - but you're correct - it will not be included in time machine backup as I have checked the back up files and Samsung is not showing. Reckon I'm onto having to buy yet another portable hard drive just for windows - or of course buy myself a new mac book!! Can I ask you please - does the drive have to be clear of everything before I change the format - or can I change it with the files still in there? Also, got any quick ways duplicating the files onto another External Hard drive (for use on the windows laptop) At the moment the files are taking 2/3 hours + to copy over! Thank you!

Lacie 1TB external HDD recently stopped doing Time Machine backups. Disk Utility recommends that the disk needs to be repaired.

I've been using my Lacie 1TB external HDD for my Time Machine backups for quite sometime. Its never given me any problems until now.
It recently stopped doing the backups, so I checked Disk Utility and it recommended that I repair the disk. How long does it take for Disk Utility to repair a 1TB external HDD?
Other things to consider:
- Cant find the disk in the Finder, I used to be able to do that before.
- When I tried to go a Time Machine backup, it said the disk was not available.
Upon using disk utiliy, I successfully verified the disk. Then I initiated the disk repair process.
The current status:
- checking file system
- Volume repair complete
- Updating boot support partitions for the volume as required.
The progress bar says "Verify and Repair volume "LaCie"" - the progress bar does not indicate how much has been done or how long it will take.
Capacity: 1 TB (1,000,204,476,416 Bytes)
Mount Point: Not Mounted
Format: Mac OS Extended (Journaled)
All other status fields blank.
Any one know how long it will take for Disk Utility to repair the external HDD? Any other ideas as to how I can get the Lacie HDD to reconnect with the Macbook and resume normal operations? i.e. Time Machine backups, accessing contents through the Finder.

Mine Failed after 3 years and 4 months of using it as a Dedicated TM Backup drive...
When I used Disk Utility for repairs... it went from 7 minutes to 4 hours and after about 10 minutes it was saying 40 hours...
So I just replace it with a New EHD...

How to store photo's on external drive and still use Time Machine and secondary back up plan

So, My Macbook Pro is now going on 4 years old and I've accumulated around 15,000 photos in iPhoto now. I would like to move everything (or at least everything older than 12 months) onto a portable external drive, but i'm not sure the best way to do this and still keep a good back up plan. My current process is the following -- I have external HD same size as my current internal drive on the MBP, which is formatted that i use Time Machine. I also have a paid subscription to Crash Plan online cloud back up that is connected to my laptop drive (CrashPlan is constant and easy, so I just USB plug in MBP to EHD a few times a month and that's it). If I were to move most of my picture/video's/important docs to an external drive, how would I back that up with Time Machine, and if I did, how would I back up my laptop drive with Time Machine also, and what drive would I assign my Crash Plan online account too? Cant seem to wrap my brain around the easiest and best method. (In short, I want most pics/video's stored off the laptop so that my HD is not consumed; but still easy to access if needed, and easy to back up) Also driving this need for a solution is the fact i would like my next lap top to be an Macbook Air, which I know I can't keep my current set up would not work. Any thoughts are appreciated.

if your internal drive has 250 GB and the external drive with the iPhoto library as well, your TimeMachine should have at least 1 TB.
I have read over some of CrashPlans support docs and it sounds like it will be able to back up and restore the iPhoto library, and as long as you restore the entire library and not single photos, it will save and restore all metadata as well.
I studied their documents to. They are saying they can backup any filetype. And they are saying the iPhoto libraries or Aperture libraries will be backed up automatically, when they are in in the Pictures folder, because the Home folder will be backed up.
On their screenshot you can see, that the libraries are backed up as a nested set of folders, and not as a package. That let's me doubt that the dependencies within the package will be treated correctly. To restore from the backup they recommend to restore the set of nested folders. What I could not find anywhere in the documentation is any information on the filesystem they are storing the backup on. If it is not Apple's MacOS Extended (Journaled, not case sensitive) the restored library may be corrupted, because the internal links in the databases may not work. Try to find out something about the filesystem on the backup servers, before you entrust your iPhoto library to that servers.

Can I migrate my data from a regular hard drive to a solid state drive using only a Time Machine backup from an external hard drive?

I just bought a Samsung 830 256GB solid state drive which I will use to replace my 15-inch, 2.53 GHz, Mid 2009 MacBook Pro's stock hard drive. I also keep an external hard drive in which I keep my regular Time Machine backups via FireWire. Would I be able to migrate all my data from it after putting in the solid state drive? I prefer not to use any third-party applications and I do not plan on replacing the SuperDrive with the hard drive that I'm going to remove from my laptop.

Can I use an external drive for a 2nd time capsule backup? Other questions too

My setup:
1 Macbook Air
1 Mac mini as HTPC
1 Mac mini as a media server (5tb and growing) with external drives.
I want to get a 2tb time capsule to back up my laptop and mac mini that i use as a HTPC. Simple enough....
Since the new gen airport extremes support external drives to a time machine back up i want to plug a CineRAID device with 4 6TB drives (12gb of storage in a RAID) and use that as a backup for my media server. Could I just plug it directly into the mac mini? Yes, but i am trying to have the lest amount of clutter possible visible. So i want to put in a closet where my router is..
So can I plug in the CineRAID into the usb port for a 2nd time machine backup with massive storage?
Option 2:
Just get an airport extreme and use the CineRAID for a backup via USB...
Also, how much space does the airport extreme support? Like i said up time I am at 5tb but its growing fast

So can I plug in the CineRAID into the usb port for a 2nd time machine backup with massive storage?
There is conflicting advice about whether a RAID setup will work with Time Machine, so you can find information that will say that it will work and other info that will say that it will not. In general, Apple says that Time Machine must "see" the RAID drive as a single partition, but they also say that you need to check with the support folks at the drive manufacturer for more details.
The only way that you will know whether it will work or not on your network, is try it out on your network.
Please let us know about your results.
Just get an airport extreme and use the CineRAID for a backup via USB...
Same as above.
how much space does the airport extreme support?
The firmware on an AirPort Extreme will support up to a 4 TB drive, but I have not tried it on a larger drive, so we'll need another user to answer on that one. Here again, it would be wise to try a few "tests" before you try to backup or transfer a large amount of data.
