I was having some quirkey things going on over the weekend with my imac and called apple support... went thru the steps, and got things working again. Seems that one of my two external hard drives was causing the glitches. Apple support had me power down my exdrives, and disconnect them. They told me to attach one at a time to figure out which one was giving me the issues and to run a disk utlity on it. WELL!!! NEITHER ONE WILL POWER UP NOW! One is a mybook from apple (about 1.5 years old) and other is a acomdata (about 3 years old) I have tried to plug them in in different outlets, etc with no results!!! ARGH! One holds all my archived jobs and one is just for TimeMachine!
Ok, try this first before you panic...one drive at a time.
Be sure the computer is shut down with one of the drives attached.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Then re-run the disk utility on the drive.
Unmount the drive, remount the drive, and see if it is readable.
If it is, back up the >Repeat with the second drive. See if it doesn't recover temporarily one or both.
Second, the disk utility on Mac is not the best, you may need a better recovery product. There are a bunch of them but one is Stellar Phoenix Macintosh Data Recovery. It isn't too expensive and it works well on FAT as well as HFS, HFS+, HFSX, HFS Wrapper.
Finally, you could try this. While I don't know about the Acom style="display:none;">Finally, you could try this. While I don't know about the Acomdata, the Mybook I believe uses a standard IDE drive. If you exhaust all other options and can get the casing of the drive open without damaging it, inside is has either a standard IDE port or the 44-pin laptop IDE...with some tinkering it can probably be mounted as a secondary drive and perhaps you will have better luck.
