After installing Lion, my iomega ex. hard drive no longer recognized for time machine

Is all my back up gone? Lion does not see the iomega external hard drive. No more automatic backup? How can I restore to Leopard if Lion doesn't recogize the Iomega?

Thank you Jon for your reply.
I forgot to mention that I am actually in the process of becoming a certified apple portable hardware technician. Just started going through the training program.
I've taken many Apple computers apart and replaced most everything in them. I had to replace my original hard drive from Apple a few months ago after it was having serious problems.
I am familiar with DiskWarrior and such programs. But that's just the thing. The Hard drive is coming back with no errors and is working fine when attached to the iBook externally via Firewire.
I was thinking it has something to do with the logic board. But being I am not quite that advanced in my tech training I am unable to answer the problem on my own.

Can you unplug the external hard drive you are using for time machine

can you unplug the external hard drive you are using for time machine and then plug it back in and it work normals because i have a mac book and don't want to always be carrieing the external hard drive every where i go so can you ?

Yes, that will work fine. It will back up normally once you plug it in again. I do this with my MacBook.

Can I encrypt a USB hard drive that's not for time machine?

can I encrypt a USB hard drive that's not for time machine?

Yes, if it has the GUID Partition Map Scheme, but only by erasing it and choosing a new format.
See #2 in Using Disk Utility.

Lion won't install can't select hard drive that is used for time machine backups

I installed Lion, agreed to the eula but both drives are greyed out. My Macintosh HD - ( this dirve is used for time machine backups) and my external drive (this drive does not use the GUID Partition Table scheme...). Though I don't use time machine, I tried turning it on and selecting the external drive with no luck. I'm stuck - any ideas?

"Backups.backupdb" if the file in Time Machine. As the discussion says, you have to find that file and trash it. Try spotlight to locate it. If that does not work, down load OmniDiskSweeper from the Internet (free) and go through an organized search to find "Backups.backupdb". If that takes too long or is too tedious, then if you have everything backed up, erase the HDD and start from square one.
Ciao.

Iomega external hard drive either 'not found' by Time Machine or is now in 'read only' format

I don't know what's going on with my iomega external hard drive. Sometimes the HD is recognised by the computer; other times it isn't; if it isn't I can restore to an earlier back up via Time Machine app; but it's like the disk isn't writable.
Ten days ago, I had trouble backing up my iMac using Time Machine. After turning it off and restarting my external hard drive, it backed up successfully.
However, today I am trying to back up my files, and TM tells me it can't find the external hard drive. Nothing has changed -- I have been out of town this past week -- but somehow my HD now seems to be in 'read only' format. It does turn on, and I could restore my computer to an earlier back up.
"Mac OS X can't repair the disk. You can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can."
Annoyingly, despite my HD not showing in Finder or on my Desktop (as it usually does), when I simply turn it off I get that warning message "The disk was not ejected properly".
Have tried verifying and repairing using Disk Utility, to no avail.
Am prompted to reformat but I don't have a good understanding of what this means and how to do it. I'm guessing this would wipe the disk clean and I'd have to create the initial back up image all over again -- I'm reluctant to do this since this HD is my only back up and if it all goes tits up I'll be up that famous creek without a paddle.
Thoughts, suggestions, input all welcome and deeply appreciated -- thank you!

It's possible a heavy-duty 3rd-party disk repair app can fix it, but they're expensive (DiskWarrior is about $100), and there's no guarantee it can do it.

That will erase it. See Time Machine - Frequently Asked Question #5.
It sounds very much like the disk is beginning to fail, although it's possible there's a bad port, cable, connection or power supply (if it has its own).
I'd suggest getting a new one, and using it for your Time Machine backups; once you have a good backup there, reformat the old one (and select Security Options to write zeros to the whole drive -- if that fails, you know the drive is toast). Use it for secondary backups, per FAQ #27. If it has failed, get a second new one for secondary backups.

My external hard drive is not recognized by Time Machine; "The backup disk is not available" according to Disk Utility

I'm not completely tech savvy, but I'm having troubles with my external memory & time machine. I'm a student, and thus its very important to me to be able to back up my computer.
I wanted to back up my Time Machine the other day. I clicked the icon at the top of the page (beside the battery icon, etc.) and the message "The backup disk is not available". I have a 500GB Seagate passport (ie: http://www.bestbuy.com/site/Seagate---FreeAgent-GoFlex-500GB-External-USB-2.0-Po rtable-Hard-Drive---Silver/9929098.p?id=1218196478444&skuId=9929098)
My macbook pro is version 10.7.5 Mac OS X Lion. My external memory is only about a year old. It hasn't been dropped or anything; it permanently sits secured to my desk.
What appears when I click "Repair Disk":
Verify and Repair volume “Time Machine Backups”
Checking file systemChecking Journaled HFS Plus volume.
Detected a case-sensitive volume.
Checking extents overflow file.
Checking catalog file.
Incorrect block count for file shutdown_time

The volume Time Machine Backups could not be repaired.
Volume repair complete.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.
After clicking "Repair Disk" this message pops up: "Disk Utility Stopped Repairing 'Time Machine Backups' Disk utility can't repair this disk. Back up as many as your files as possible, reformat the disk, and restore your backed-up files."
I don't want to wipe my memory on my external disk just in case the disk doesn't restore (as I do not have another disk to back up my computer on to).
What is going on? Why is this happening out of the blue? How can I fix this?

Sounds like it either has, or is about to die.
If you don't need anything off the old drive, then yes, replace it immediately with something a little more reolaable. I use WD Caviar Black personally. But anything that has a known low failure rate.

My mac mini quit recognizing the external hard drive i am using for time machine.

I have an IOMEGA external hard drive hooked up to my mini for Time Machine. It was working for about 4 months then quit. The PC will not recognize the hard drive and I have switched usb cables and tried different ports to no avail. Any help would be gladly appreciated!!

Yes, that will work fine. It will back up normally once you plug it in again. I do this with my MacBook.

La Cie Porsche Design External Hard Drive no longer working with Time Machine since update to Yosemite.

My La Cie Porsche Design External Hard Drive USB 3.0 is no longer working with Time Machine. Is Yosemite the cause? How do I fix?

Can you see the drive in Disk Utility? If so, try selecting it and using the Mount button in the top menu. You can also run repair disk and repair permissions.

My external hard drive has been used for Time Machine, now it doesn't work on my TV?

I bought a new external HD 3TB, I used it as a back for Time machine and also wanted to use it for watching my movies etc on my TV. The TV won't recognise any video's on the HD. Is there some reason this would happen due to using it for Time Machine?

If you are talking about a drive that you connect directly to your TV, typically they will recognize only drives formatted in some specific way & only certain kinds of movie files. You can check your TV users manual or its manufacturer's web site for information about this, but in general they will not recognize drives using the format Time Machine requires.

Setup of USB Hard Drive on Airport Extreme for Time Machine

Hi all,
I upgraded to Mountain Lion a while back and am running the latest Airport Utility. Here's the problem: I can't get Time Machine to work anymore with my USB Hard Drive attached to my Airport Extreme. Is this setup no longer possible under Mountain Lion? Do I have to buy a Time Capsule? For the last couple of years I've had two MacBooks backing up with no problem to the USB drive connected to the Airport Extreme. Any advice would be appreciated!
Thanks,
Chris

While you can do this as Kappy points out, there a few details that you might want to consider before you make the move.
1) Time Machine backups to a drive at the USB port of the AirPort Extreme are not supported by Apple. While this does seem to work for some users, others (like me) have difficulty with corruption issues. The bottom line is that this is not a reliable method to back up your important data....and, no support or help from Apple if you do have difficulties.
Reference this Apple Support Document to confirm:
"Time Machine can’t back up to an external disk connected to an AirPort Extreme......"
http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
2) If you move the iPhoto library to the hard drive attached to the AirPort Extreme....your original or master library now resides on that disk.....and you have no backup for the library.....when, not if.....the drive has a problem.
3) You might want to post in the iPhoto forum to ask if it is still an iPhoto requirement that only one user at a time can have iPhoto open with the shared library arrangement.

Freecom hard drive no longer recognised by Time Machine

I have a 1TB Freecom Hard drive which has worked fine for nearly 3 years. It has suddenly stooped working, no drops or knocks. It doesn't show up on disc utility. I've tried other USB cables and plugged it into another macbook. Not picked up. I can feel and hear the disc spinning, no clicking or crunching. Freecom not very helpful at all. Any suggestions?

All things must pass.

My external hard drive stopped being recognized by Time Machine. Any fix? being recognized

As the title of the question suggests, this happened suddenly, after months of trouble-free integration with Time Machine. If I bring up the disk utility it recognizes the drive, but won't perform any repair or other operations on it. It indicates the disk is unformatted.
Any way to repair/re-format this back-up drive, or should I just toss it and buy another one?

Sounds like it either has, or is about to die.

Adding external hard drive to airport extreme for time machine error

Hello,
I recently bought an airport extreme that I wanted to combine with an external hard drive in order to do wireless time machine backups. I hooked this up and the hard drive shows up in the devices menu.
However, when time machine starts to backup, I get the following error:
"The backup disk image “/Volumes/Blackmer External MyBook/Benjamin Crispell Blackmer’s MacBook Pro.sparsebundle” could not be created (error 1)."
When my computer is connected directly to the hard drive, it works fine.
Any ideas on how to fix this?
Thank you.

It is important to understand that Apple does not support Time Machine backups to a drive at the USB port of the AirPort Extreme. So, that may be an issue here.
Despite this, users try it anyway. Some appear to be successful for a time, some partially successful, some can't get it to work at all.
Even if it does appear to work initially, corruption issues may occur down the line without warning. Having tried this myself as a test a few times, I can attest to that.
If you want to try this anyway, the two important things to check are.....
The drive must be formatted in Mac OS Extended (Journaled). Other formats will not work
You almost always need to use a powered USB hub...even if the hard drive has its own power supply....because the USB port is under powered on the AirPort Extreme
You might also want to consider a secondary backup plan to protect your important files

Hard drive to airport extreme for time machine and iPhoto library

Can I buy an external hard drive and connect to my airport extreme to be used to host my iPhoto library. Meaning that no mater what Mac I upload an image to iPhoto in, it is referencing the same library on an external drive.
