    Ever since launch day i have always kept an HDD attached to my ibook. so today i decide i wanna take it out of my room (where the hdd is), so i try to eject it. it doesnt eject. so im looking if its transfering any files and it wasn't, so i take it out w/out ejecting it. later when i plug it back in, my HDD spins up and doesnt mount. i go to disk utility and see that the disk itself is mounted, but the data partition isnt mounted. i click mount and says "mount failed, try using first aid". so i hit repair disk and it doesnt find any errors and my disk still isnt mounting! is there a better, more thorough disk repair program i can use? plz help

    Have you relaunched the Finder, or restarted? I've found 10.5 Finder to get confused, at times, as to what is mounted or unmounted. It's happened a few times, and usually just relaunching Finder will "fix" it.

    Was this a new drive for Leopard TM, or one you've used before?

    If it's USB bus powered, some models can be marginal. Try using a/c adapter, if available.

    Just throwing ideas out there. It doesn't sound like a drive hardware problem, though.

    I had a similar problem which I think arose from trying to make an existing partition on an external drive into a Time Machine drive.

    It wouldn't unmount the disk for repartitioning... The solution was to move my non-TM files to another drive on the network, and then do an Erase Disk in Disk Utility, and reformat the entire drive. After Erase Disk, the volume was unmountable for reformatting/partitioning. I don't know how it fares with multiple partitions but I kept it all one partition after reformatting and it worked.

    I'm having a similar problem - my external Time Machine HDD has now become corrupt. I get the message "The disk you inserted was not readable by this computer" when I switch it on.

    It's a single partition USB2 disk with external power, used exclusively for Time Machine.

    I suspect I switched it off without unmounting it first. I've always had worries that OS X can be a bit fragile when it comes to disk handling. It really sickens me to say this, but I've never had a corrupt disk problem with Windows in more than 15 years, no matter how roughly I treat a disk. I guess I'm just going to have to be a lot more careful, but it's really easy to forget to umnount before switching the HDD off.

    I know it's my fault for not being more careful, but it just seems to go against Apple's usual "foolproof" approach, especially with something as critical as a backup.
