I stoped working yesterday and didn't try this comercial diskW*** i thought that would be free.
doesn't look good for my loved iMac, HardDrive doesn't get detected in FireWire Target mode. Now he's at the Apple Service provider. I hope I'll soon get the call that most of the data could be recovered and averything will be fine ....
Meanwhile I'm trying recover the data I could save....

at least the next week I think I'll only get a mocca cup of sleep ;(
