Time Machine dismounts internal drive

Hi,
I have TM dedicated 2TB drive in bay 4 that gets dismounted each time TM completes backup. I have to go to Disk Utilities, and mount drive manually, so TM resumes backing up. Has anyone seen this problem before? I had no problems with 500GB drives, and I don't use any power saver modes for my mac (Mac Pro early '08).
Thanks

It sounds like the backups are failing, causing OSX to dismount the drive. Click here to download the +Time Machine Buddy+ widget. It shows the messages from your logs for one TM backup run at a time, in a small window. Navigate to the backup in question, then copy and post all the messages for that run here.
Or see if any of the messages are listed in the Contents of the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
It will show you how to locate the message(s) that describe the problem, then help you fix it.
If that doesn't help, post back with details, including all the messages, your setup, what you've done, and the results.

i previously posted this question, but I mistakenly clicked my own comment as the correct answer. i think this makes the thread appear to be finished; so, because i'm still not completely sure what to do, i have attempted to copy and paste the discussion here:Sorry.
Just got Prosoft drive genius 3 software, and it's telling me that the external hard drive that i am using for my time machine back up drive needs to be defragmented. is it wise to do this or should i not??

If your backups take a few seconds longer, so what. I say leave it alone.Beige G3, G4/867, G4/dual 1.25 MDD, MacPro'09 w cheap SSD, Mac OS 8.6 or Earlier, and 9.2, 10.5 and Server - LW IIg, LW 4/600, ATalk ImageWriter L

Let's hope a couple things: that you have bootable clones of your drives also; that the backup drive for TimeMachine has over 3x capacity of the data you plan and are storing. I would also switch TM backup drives so you have a 2nd. Fragmented free space affecting performance happens when the drive is too full which may mean there isn't enough free space for a full backup set. 1.5TB for backing up 500GB, while WD Green 3TB is $140 and WD Black 1.5TB is, about the same price. I'd be worried about the integrity and directory, and whether you can afford to lose that drive. Defragging is also a very slow operation. the ideal: to just clone a drive, or start over with another drive and wait. cloning TM volumes has not been done or has it? SuperDuper hoped to but I don't think they or Bombich's CCC made it there. Trouble with highly fragged is when free space gets to 20% normally, 1/3 or so though for TM volumes, and finding where and a chunk of space for the file being written. Does TM use large spare image files of like 2GB? Best would be to ask in the TimeMachine section Snow Leopardhttps://discussions.apple.com/community/mac_os/mac_os_x_v10.6_snow_leopard?view= discussions#/?tagSet=1009where there are some good FAQ and tutorials, and people that know the ins-and-outs and shortcomings.

my boot drive is my internal hardrive which is a 250 GB drive. The drive i am using for TM is 500GB, but you are saying that is really too small. TM, as i understand it, creates a copy of everything, and then subsequent backups record any changes that were made since the last backup. and what do you mean "bootable clones" and do you mean for my internal hard drive AND each of the 3 external hard drives that i have? i'm using one of the three for backup using TM, and i am storing movie files on the other 2. i work at a church, and we use many short films that we purchase online. i then import that file into iMovie to give my volunteers a consistent second and a half of black before the clip and 4 seconds of black at the end of the clip. This provides smoother transitions, i've found, than trying to use most of the clips in their original form. i then have been filing these away in folders on the other 2 hard drives. Regarding the TM drive. Drive Genius is telling me that "the used space on the volume 02 [that's the name of the drive] is 25% fragmented (59.14% of total space).
btw, Time Machine keeps:hourly backups for the past 24 hoursdaily backups for the past monthweekly backups for all previous monthsand the oldest backups are deleted when your disk becomes full.
Mac Pro, Mac OS X (10.6.8), LaCie d2 Quadra 500GB external driv

1st) A fragmented drive is not evil. It will not hurt anything. At worse it might slow down reading a file. However, as has been pointed out by others in this thread, who cares as this is a backup device, not a device you are going to be reading a lot.
2nd) The time you spend defragmenting the drive will far exceed the time you will save when writing new data to the drive.
3rd) Defragmentation will just increase your energy consumption, as all the reading/writing needed to move the files around in order to defragment it, will cause the drive to consume more energy than if it was just sitting idle waiting for the next hourly Time Machine backup.
4th) Defragmentation (if done frequently) may shorten the life of your drive. Not mentioned in "3rd" above is that the extra energy used translates into heat, plus you are moving the read/write heads back and forth all of which affect the drives mechanical and electrical components.
NOTE: There are situations where having a defragmented drive is useful, but mostly it has to do with needing to stream media at a high rate of speed, and fragmented files can affect that. However, a backup drive being used for incremental Time Machine backups is not in that category, and most home Mac usage does not need a defragmented file system either.

Time machine says my drive is full, but it's not

time machine says my drive is full, but it's not. it is a 298 gig external drive with 51 gigs available. my internal drive on my lap top (the one I am backing up) is a 148 gigs with 44 gigs available. the backup folder on the external drive is
152 gigs.
how can i fix time machine so it can figure out that the external drive isn't full?

Thank you both for your replies. Something is seriously wrong with a backup program that needs that much extra space! So much for incremental back ups.
It doesn't, necessarily. We still have no information on what's going on with your situation.
It's a back up for a laptop and I would like to connect it to the backup hard drive once a week or so, but from what I read time machine only works one way... for a computer to have it active all the time.
No. It works BEST that way, but isn't required.
That just won't work for me for many reasons. Most importantly, time machine slows up my computer and I have to leave it off to run my applications.
Then something else is wrong. Again, without any details, we can't help you determine what.
There is no setting to have it turn on in the middle of the night or once per week.
Not in TM itself. But there is a free 3rd-party app that will do this, Time Machine Editor: http://timesoftware.free.fr/timemachineeditor/
It would sure be nice if I could back up when I want. Seems like time machine is just one of those ideas that apple didn't think all the way through.
You can. And TM works just fine for most people. There is something unusual in your setup, or the way you're doing things, that's causing your difficulties.
Let's be clear: if you'd like some help with this, please answer my previous questions and download and post the messages from the wIdget.

I used time machine, now my drive has failed and all my files are lost.

Which one, the TM drive or the internal boot drive?
all my files are lost.
Where? on both drives or just TM or the internal drive?
any one know how to get the max osx
yea, if we knew more details of your machine and what you had before and later
to see the drive again so i can retrive my files
I don't know what drive failed.
I'm thinking here your internal drive failed? Was it replaced?
You have a blank internal drive and a TimeMachine drive and your asking how to reinstall OS X so you can restore from the TimeMachine drive?
How are you getting here? Another machine or device and what is it?
We need more details of your situation please.

Had hard drive renewed due to product recall (iMac) backed up complete system on time machine . Had the drive done got mac back tried to reinstall from time machine .The new drive tells me that the space has been taken up but can't find where the file have gone. Need to free up the space that the ghost file take up so I can drag drop from ex drive onto harddrive

Here's the scoop, new friend.....
When you boot into Time Machine you'll get the same OS X Utilities screen as you would if you booted into the Recovery HD. So, from there go into Disk Utilities to erase/format your internal drive. After that's done, back out to the OS X Utilities screen and select the restore option. Just follow the prompts to select the TM back up date you want to restore from and where to restore it to. Pretty straight forward.

Vault & Time Machine on same drive?

Hello,
I was wondering if there is a way that an Aperture vault can be created on an external hard drive that is already used for Time Machine.
The drive is of size that I would not use it all and would like to back up my Aperture pictures which are excluded from the Time Machine backups.

Yes, you can store a vault (and anything else) on a drive used for Time Machine. Mine's set up this way and I've had no problems.
However, once Time Machine fills up all the free space (as it will eventually do) then you'll be unable to update your vault without manually deleting older Time Machine backups.

How do I access my iphoto library on time machine backup external drive using Lion, originally saved from old computer and system

how do I access my iphoto library on time machine backup external drive using Lion, originally saved off old computer and system. It's not letting me open the folder???

Once again here's how to restore an iPhoto Library from Time Machine:

HT3275 Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive. Could not complete backup to media share. The network backup disk does not support the required AFP feat

Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive. "Could not complete backup to media share. The network backup disk does not support the required AFP features." What are AFP features and how do I get Time Machine to backup to my current external backup?

This means that your NAS does not support the required encryption. Update your NAS to the latest firmware or ditch it and buy a Time Capsule (they are the most reliable when using TM).

Time Machine with 2T drive connected to Airport Extreme base via USB

I got this to work - Time machine recognizing the drive in its "choose backup disk" menu.
I used it to store Apple Lossless audio on a big iTunes library, as well as for my Time Machine backups.
Whole system ran fine for 4 months until last week: while I was using iTunes with that remote library, adding audio to it... "Airport has detected a disk error"... My 2TB of disk turned into a very expensive brick.
The disk had to be recovered with Disk Warrior, detecting "19,753 directory entries with incorrect text encoding value" as part of a nice one-page-long list of other errors.
SINCE THEN: no matter what I do, the disk does not show up in Time Machine, even though I can access it via the network exactly as before.
Any ideas are welcome!

Apple does not support Time Machine backups to an AirPort disk (a USB drive attached to an AirPort Extreme Base Station (AEBS)). (ref: Mac OS X 10.5: Time Machine doesn't back up to AirPort Extreme AirPort Disks) Although folks, like yourself, have gotten this to work initially, the long-term stability of the TM backups is highly suspect and why Apple doesn't support it. Sorry!

Has anyone successfully used a "WD My Book for Mac" via NAS (plugged into USB port on router) as a Time Machine back-up drive?

Has anyone successfully used a "WD My Book for Mac" via NAS (plugged into USB port on router) as a Time Machine back-up drive? Apple support tech tried to tell me it wasn't possible and that the only NAS Time Machine could back up to is the Time Capsule, but I'm not buying it. I know it's doable, but I'm having a hard time figuring out which External HDDs will work and which ones won't. If not My Book for Mac, is there an External HDD that will work? (Running OS X 10.9.1 - Mavericks, btw...)

Given the nature of backups, my recommendation has always been to use a strategy that is unequivocally supported by Apple. As you already determined Apple Support unequivocally informed you that your proposal will not work, unless your router is an Apple AirPort Extreme or Time Capsule.
The exhaustive list of devices supported by Time Machine amounts to the following:
AirPort Time Capsule's built-in hard disk (any model)
External USB hard disk drive connected to a Time Capsule (any model)
External USB hard disk drive connected to an AirPort Extreme (current model only)
A hard disk drive directly connected to your Mac
That is all.
Use whatever backup device you want, but you should be aware that this site is full of reports of misery from hapless individuals who had been using NAS devices for Time Machine backups, only to find that they were incomplete, corrupted, or useless when they were required. Apple won't care if you lose your data while using a Time Machine configuration specifically excluded from their technical support documents.

Running more than one time machine back up drive

I have a back up drive assigned as my offices time machine back up drive.
I need to set up an off site back up drive too. I know that time machine will only allow a connection to one back up destination at once.
What problems could i encounter if i set up a off site drive as another time machine drive, disconnect on site drive and connect the off site drive to back up.
Thanks

That will work just fine, other than the hassle of having to tell Time Machine every time you swap.
Give the drives at least slightly different names (that's for you; Time Machine knows they're different).
Each set of backups will be complete and independent. When you do a backup to either one, it will contain all the changes you've made since the last backup +*to that drive.+*
The first backup after a swap may take a bit longer than usual, as there may be more changes to "catch up" with, but otherwise there should be no troubles.

The disk drive in my iMac 8,1 has stopped working, so I now use an LG 8x Slim Portable that works. However, every time I use the LG drive, I lose contact with my Time Machine back-up drive that has to be deleted and reinstalled. Help!

It's not Logic that can't find them, it's your Komplete apps, though if you did exaclty as you say I can see no reason why they can't.
Do you know where the apps installed them in the first place? I chose a non-standard locarion for mine, but I'm sure it installs sounds to your documents folder/native instruments/name of app.
Go into the prefs of each app and choose the library location button on the library tab and point it to the relevant folder in documents/native instruments and see if that works
