Time Machine ejects my Ext Drive

Hi,
I hooked up an external (1.5TB) drive to my MacBook and ran time machine. It said backing up 103GB. Everything went fine until about 14GB and somehow ejected my ext drive. The drive disappeared. I unhooked and put the drive back. Ran TM again. This time it was backing up about 1KB a minute or so. And soon spit my drive again - showing a failure to back up.
I am not willing to reformat my ext drive because I have put a lot of video files on it.
Any suggestions?
Thanks

That may be a problem. How is this drive formatted? Was it previously used on Windoze?
The most common cause of an initial Time Machine failure is the drive not being set up properly. Check it via the instructions in item #C1 in the Time Machine - Troubleshooting post at the top of this forum.
As mentioned there, if the formatting is correct, see item #C2 for other possibilities.
There is another consideration here; since you already have other data on that disk, you really should partition it, so TM has it's own, exclusive space. Otherwise you're likely to have conflicts later on. See item #3 in the Frequently Asked Questions post at the top of this forum.

Time Machine ejecting internal hard drive during backup

I originally posted this in the Time Machine group. It was suggested I post to the Xserve group.
We have an XSERVE running 10.6.4 server. It has 2 internal 1TB drives. The plan is to use one as the main drive and the second as a Time Machine backup. This used to work in 10.5, but since about 10.6.2 or so, it has not worked correctly.
Time machine will come on, begin the backup, and then error off with a message that the drive has been ejected. I have erased the drive, but still no joy. I have partitioned the drive, still no joy. I have verified the drive repeatedly, and all is fine. I can copy files to and from the drive until the cows come home, and all works fine, which means I do not think it is the drive itself. Activate TM, however, and it will fail before the first backup is completed. The only way to get the drive back is to do a complete power down and then power up. Needless to say, that is not a good thing for a server that we rely on.
Any ideas?

No, it is not always at the same point/file/bytes transferred. It will vary from a few GB (say 3GB) to quite a few GB (say 30GB). I would add amongst the things I have done was to:
Perform numerous Disk Utility Checks. Never any errors found.
Erased the backup drive on multiple occasions. Double checked the GUID and format.
Partitioned the drive and tried backing up to a new partition. (No joy there either)
Copied lots and lots of data from the root disk to said partitions to test them. All went fine.
It really is Time Machine that is causing the issue. I can use the drive all day long as long as TM does not run. When it does, I eventually get a failure message that the drive has been ejected.
While I have not tried making a partition on the home drive (I'd rather not, lots of data there, make users mad, and since TM is not working, I have no backups at present), I do limit the data that is being backed up to JUST that of the system. /Users is being excluded at the moment. So I doubt there is anything out of the ordinary in the system. And, yes, I did a disk check on the root disk and all is fine there too.

HELP: Time Machine super weirdness, ext drives just disappear...

Hi all and Merry Christmas!
I bought 2 brand new Maxtor One Touch 1TB Ext FW800 drives, intended one for Time Machine and the other possibly for backing up purposes or SuperDuper (http://www.maxtorsolutions.com/en/catalog/OTIII_Turbo/index.html)
*Both drives have the same result:*
I mounted the drive each for the first time, and use Disk Utility to erase (format) again, simple format, no raid no nothing.
Then I set up Time Machine to do the 1st initial back up, but after a while, into a few GB of data back up, the ext drive *just suddenly unmount and disappear from the Desktop*. Twice for both drives. Now when I *turn the drives back on, I can't get them to mount... HELP!!*
Did I miss something, did something wrong or I should have format it as a RAID drive as it should be?
*But right now I need to "rescue" the drives back, how do I do it?* OR that the drives are DOA and somehow faulty?
Thanks again and Happy Holidays, hope someone is reading this... cheers!

Hi. I did a Erase like any other internal or external Mac disk - Journaled, not FAT, etc. One simple partition, no GUID etc.
Anyway, I am very happy to report that the Time Machine drive is now working fine, here was what I did before that failed:
1. The 2 1TB Ext FW800 drives were connected to a Belkin FW800 Hub, the hub is then connected to the sole FW800 port behind the iMac
2. I gave the designated Time Machine drive a custom icon, using Get Info/Copy & Paste the icon graphic.
So I remove the hub, connected the 1st drive to the FW800 port, and the 2nd one daisy chain to the first drive. This actually remounted the 2 drives and I re-format and re-erase them again.
This time my designated Time Machine drive I left it alone as it is, no icon pasting whatsoever.
Did the initial backup, the FW disk icon immediately changed to the Green Time Machine icon drive, the process took quite a while but has completed and successful.
So I am not sure whether it's the combination of the above points 1 & 2, maybe the hub was faulty (it's new), or because I change the icon. Anyway, something learnt.
Cheers

My iphoto library disappeared. i am trying to restore my library from time machine -- from an external drive -- but everytime it tries to copy my library it tells me it can't do it because i don't have access to my iphoto library??!!! help!!

My iphoto library inexplicably disappeared! i am panicked but i do back up by time machine to an external drive and also to JustCloud. I am trying to restore my iphoto library from a back up on feb 28, 2014 and it says it's copying but then gives me a message that it can't do it because i "don't have authorization to access iphoto library"?! what does this mean? i really want to get my library back on my mac. Also if anyone knows why this happened or where my photos might be on my computer, i'd appreciate help with that, too.

Thank you Terence for your help. I was able to restore my backup from my time machine ext drive to a new 1tb seagate ext drive. so i felt sort of ok. but yesterday that older ext drive i used for time machine wouldn't open! i called applecare and they trouble shooted with me and said it's probably a goner and data is probably corrupted. it's only a few years old and i'm very careful with it. my husband accidentally dropped my new drive last night -- i know, unbelievable, i was SO upset, poor guy -- but I'm so stressed with all of this. i have 10 years of photos and videos. so now i only have the one newer drive with a backup. i have to buy another one today to backup again so i at least have two backups. i tried to delete a ton of files last night to free up the 30 gb of space i need to get my full library back on my mac. i have 90gb free and deleted 7 years worth of photos i had on picasa that were in my "pictures" folder and also a ton or random photos and videos i had in that same pictures folder and thought that would give me the 30 gb but it hardly freed up any space at all! do you know why that is? all of this stuff is really a pain and really stressful. thank god i did have a backup in the first place but now i am panicked the one i have left will somehow crash. especially after my husband dropped the drive lastnight! it didn't fall far and fell onto a wood floor and seems fine, but after my older ext drive crashed yesterday -- and i lost my entire iphoto library a fewweeks ago off my mac -- i feel cursed. any answers you have would be great. thank you.

Sorry, but no.
Time Machine will backup your Mac, but not the hard drive attached to the AirPort Extreme.
Time Machine will back up a hard drive only if it is attached directly to your Mac via USB or FireWire.

Time Machine backing up a drive which is no longer connected

I have recently removed (and replaced) one of my external drives. I have Time Machine running on third drive. When I look at my recent backups, Time Machine is still creating a folder (and contents) for the drive that no longer exists. The only difference being, it is putting " 1" after the drive name. What is going on?

*Bump*
I'm going to be switching my Timemachine drive shortly, and I'm considering not transfering my backs, just to get around this bug. Obviously that's not ideal, so if anyone can shed light on this it would be great.

Time Machine encryption - after restart, drive won't mount

Hi all.
I enabled Time Machine on my Drobo drive, enabling encryption. All was good, Time Machine started encrypting away.
I restarted my Mac, and now my Drobo won't mount.
In Disk Utility, it looks like this:
I'm unable to verify, repair or mount the disk.
I wasn't prompted for the Time Machine encryption key, I assume that this is stored in my Keychain and unlocked on the fly?
But regardless - I'm unsure of what to do next! I've got quite a bit of data on the drobo, and didn't expect it to render the drive completley useless. I'll be gutted if I lose my files on my Drobo besides the Time Machine backup I had.
Any help, suggestions, advice would be much appreciated.

Can I use Time Machine as a backup drive for my Vista 32 PC?

I cannot see any of my Mac computers or Time Machine on my network through my Vista PC, even though I have a wireless card in the PC which can connect wirelessly. I have my PC sitting next to my Time Machine that is the hub for my network. I am connected to the internet via ethernet connection daisy chained through my Time Machine which is connected to my cable router.
I cannot figure out why my PC cannot "see" my Imac, emac, Time Machine, and macbook that are all connected to my wireless network. The PC and Time machine are the only devices with an ethernet wired connection.
I would like to use the Time Machine's 1 terabyte drive to back-up my Vista PC.

I would first set up my mac and vista to do simple file sharing and then work my way from there. If you are unable to figure out simple fire sharing i would go look on other forums or advice. Its rather simple to do but it can also cause a lot of headaches. I have wanted to connect my mac and windows server to my network for a while and just recently figured it out.

Using Mac Mini, Time Machine and External Hard Drives as a Backup Server

Hello...
I own a graphic design studio and have been looking for a long time to create/buy a no-thinker backup system for my macs. I have 4 workstations that I would like to backup to one central "server".
So what I was thinking was buying a Mac Mini, 3-4 external USB 2.0 Hard drives, external Blu-Ray burner and upgrade all our systems to OS 10.5. What I need to know is, will each work station with Time Machine on it back up across the network to a specific drive on the Mac Mini? If I have each workstation automatically mount one external across the network onto the desktop, will Time Machine recognize that hard drive as a legitimate drive to backup to?
Having the external Blu-Ray disc burner will give me the ability to burn data to a disc so I will have a way to take some of my information off-site. Since we are a graphic design studio, we use large amounts of disc space and regular DVD-R (4.6 gigs) is just not enough to back up some projects.
Can someone enlighten me, and tell me if this would work or not. It's the only way I can see me creating something that has enough space, will back up automatically across the network and allow me to make off-site copies of my data without spending $5,000.00.
Thanks for any comments you might have on this topic.

I'm a member of a freelance graphic artist team and have been scraping by with my MacMini and CS3. I recently obtained a used iMac (approx. 2 years old) and, instead of painstakingly transferring everything left on the Mini to the iMac, I wanted to know if it's possible to turn the MacMini into a pseudo external hard drive using the FW800 port.
I already had an external attached to the Mini and plan on using that as well, but I tend to hoarde information and run out of space really quickly. So keeping the mini around, preferably in a way that I can access it as an external through my iMac, would be perfect. I have very little experience with networking and don't have a wireless connection (yay modem cables!) so I don't quite know how to figure this out.
Has anyone done this? Would a FireWire 800 work? Would I need to set up a network between the two and use them as independently connected computers?

Time Machine with multiple hard drives

I use a very large external hard drive for time machine. I back up to this time machine, the two hard drivs that are inside my macbook pro, 512GB ssd, and 250GB SSD that is in the optical drive. I then backup a 1TB portable hard drive which holds all my movies and then I backup another 1Tb portable hard drive which holds all my "reserve" files, which means they are files that are no longer important to be on my computer. Old pictures, music, etc.
Now, I can't plug all of these drive's in at once. So, let's say I have to do a backup and I have nothing plugged in but the time machine external hard drive. Will it only backup the two hard drives that are in my computer and then later somehow let me go and restore the other drives? Or will it attempt to restore all 4 drives at one time? Because if the one in my computer mess's up, the other's may not be messed up and I do not want it to restore those.
I have used Time Machine before to restore my system. But never since I have started adding extra drives for Time Machine to backup.
I am also planning on adding, yet another drive for it to backup which is a 1TB portable hard drive that I keep raw files on for photography. I'm just curious how this works when and if the time comes.

well superduper is FREE, CCC isnt.........CCC can do the daily updates etc,. Superduper DOES NOT. the CCC and Superduper CLONES are bootable.......so, if your HD crashes, you can throw in the CLONE, and youre back and running in mins, rather than hours etc .
You should NEVER consider a backup a "backup", ........2 copies is 1, and 1 is none.....always have 2 copies of important files / pics etc etc,......... DECADES of work have been lost by people who thought their stuff was safe because they had a (meaning 1) backup.
Simplicity? Yes, Simplicity is my religion. CLONE your HD with programs and settings, ......and use a 2nd HD updated daily / weekly etc (preferable 2 such 'seecond' harddrives, copies of each other) with all personal stuff / work / pics / vids/ documents.....
superficially time machine is simpler, "smack a button and everything backs up".......in REALITY however when it "all goes up in flames"................the pro method (and my method) is QUICKER and more reliable by far to get down and running.
Ive restored other peoples from total crash and burns via Time machine.......and "my" way............my way always ends up faster by a mile. Also personal / work etc files are kept autonomous to the system data / programs OS,.....as it logically should be.
Time machine is the fastest incremental backup........but its as slow as paint peeling if you need it in case of a TOTAL CRASH.......wherein a bootable clone can be thrown in , in less than 20 mins.

Time machine restore from network drive kernel panic

I had a late 2013 macbook pro 15" retina, I was backing up with time machine to a network drive (western digital my cloud). All of my backups are there and the data looks valid. In April I ended up selling the macbook pro, then recently I bought another one and attempted to restore from the network drive.
I chose the option to restore on boot from network device, it properly detects and lets me browse my previous backups. I choose restore, the restore will run for a few hours and then reboot with a kernel panic.
panic(cpu 0 caller 0xffffff00184c0ac1): "Unable to find driver for this platform: \"ACPI\".\n"0/SourceCache/xnu/xnu-2422.90.20/iokit/Kernel/IOPlatformExpert.cpp: 1541"
I've tried a few different backups, one from April, one from march...both result in the same error. Any ideas why this would happen?

Time Machine full system restores only work if the backup disk doesn't need drivers separate from Mac OS X to mount. To make a long story short, you CAN'T do a full system restore with the disk your backups are on.

Time Machine and a network drive combined

I figured out how to connect Time Machine with a network drive (like LaCie Mini). It works great, the only thing is, everytime I restart the mac I need to re-connect manually to the server in order TM can run.
I wondered why OS X gives not the option to connect to certain servers AUTOMATICALLY when starting up?
thanks for help

Well,
PLEASE can you tell us how you figured out how to backup to a network drive because Apple tech told me you could not do that!
To your question though, on those LaCie drives, you have to log in with a password, right? On the drives I have used with clients, although the password was filled in for me, we had to press OK every single time to actually connect to the drive... I could not bypass the login procedure on the drive, it had nothing to do with OSX. You might serve yourself well to see if LaCie can offer you a way to connect to the drive automatically?
Although I know nothing about scripts, could you just get a script to run automatically at startup to connect you to that drive?
I'm interested in this topic so please feel free to share what you know and your experience with it. Thanks in advance.
I was also frustrated to find out that I couldn't even back up via Time Machine to a drive connected via USB to my Airport Extreme... I mean come on!

External Drive with Time Machine, booting from external drive with utilitie

I'm using Time Machine now with
a LaCie 1TB external hard drive.
Everything works fine.
But, I've been wondering:
Can I place a program like TechTool
on the external drive (that Time Machine uses)
and boot from that external drive.
I would like to be able to do that,
because diagnostics and repair programs
only works properly and fully when they run from
external drives. Anything on the internal drive can be repaired
and examine. Impossible to do if Techtool is on the same
drive that's been examined.
Any thoughts as to what I should do?
Thanks
iMac, Leopard, Time Machine, Lacie Quadra 1TB drive.
P.S. Stupid question: If my computer crashes, and I reboot from Time Machine
(from the external drive) how does the computer know which backup to take ?!?
Isn't there many versions of the OS on the Time Machine backup taken at different times?

As V.K. says, you can't boot from TM backups.
But you can restore your entire system from any one of them, per the procedure in #14 of the Frequently Asked Questions *User Tip,* also at the top of this forum.
You can also selectively restore from them, while running normally. See #15 in the FAQ Tip.
