Itunes ?

When i took my HD downstairs and hooked it up to that mac, i get this message...

The disc "music" was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data...

Does this mean my HD is fried? It was all working well until i tried to upgrade to latest itunes. Maybe it was a coincidence?

OK Sd, if it were me I would take the external HD back to the original Mac and run a repair utility on it. Use Apple's Disk Utility if that's what you have. There is a chance you can save your music.

If you're using Disk Utility and it doesn't seem to do anything the first time, repeat the repair process a few times. BTW the big gun in repair programs is DiskWarrior, but it costs.

Post number 7 in this thread will be of interest. Perhaps the problem is OS-related, triggered somehow by the update you did, and is not a problem with the drive itself.

If the problem does end up appearing to be drive-related, as indicated by the presence of similar symptoms when it is connected to different computers, if the drive is formatted in FAT32 and Toby's good suggestion does not resolve the problem you could try connecting it to a Windows computer and running the Chkdsk utility. Post back if you'd like further information about that, indicating which Windows OS is being used. I have found Chkdsk to be very effective in repairing corrupted disk file systems, which may be what is causing the problem.

Good advice from Al. One thing to try before you go either my route, above, or Al's, is unmounting the external disk (drag its icon to the trash or use the Eject button), then reconnecting it to the computer. See if the same message comes up. Sorry I didn't think of it earlier.

Do post back with an update if you get the chance.

Ok guys. I have tried a few things so far. The HD shows up on the desktop but not when i look for it as a new library option.
I tried the disc utility a few times. It didn't work. I tried it on 2 different Mac computers and it says the same message on both.
I will try to do the time machine backup to see if i revert to before i made the update to the latest version of itunes, if that works.
Luckily i did transfer all the info to a new HD just the other day.
Refresh my memory, when i add the new HD, do i just "add file to library"?
