Probably the controller. When the unit is plugged in it shorts out the powersupply ( only the power plug not the IDE ). I've since placed a new harddrive in the system and the system is up but I have to access his business data file.AFAIK, there's no such thing. Is it a physical problem with the drive or might it be the controller card?
If it's the controller card you can try to find the exact same model / revision and swap them out to get the HDD up. If it's a physical problem with the HDD then you're talking platter swap in a clean environment or something similar.
Well if that's the case then it's not worth fussing around with. Any suggestions on a recovery center?It might be the controller, but I'd be more inclined to look at the drive motor in that case.
edit: Did you try the drive connected outside of the case? Small chance that it might be a case ground short which only shorts the PSU through the case.....
I might be able to help, got a couple WD80's laying around, and I've (successfully) performed controller swap data recovery in the past(long story, HDD PCB caught on fire). What revision number is it and PCB revision?Its the Western Digital WD800.
