Drive listed as unknown device by mac os ...




By mfeldman on Feb 13, 2008

" "
Terabyte drive connected to iMac 2.8 GHz dual core Intel by an 800 to 800 firewire hums but does not light up and is listed by the computer running Leopard 10.5.0 as unknown device, model and manufacturer.Computer does say max speed is 800mb/sec but connection speed is unknown. I think my connections are good and proper and I powered up as the last step. Apparently the startup software WD states is on the disc did not install the drive so I assumed I needed an upgrade for compatibility. I tried WD button manager software to no avail. I need help to find the proper software if indeed that is the problem. Thanks

- to lovepirat:
I assume you mean I should format the WD drive.How do you format a drive that is not recognised by your motherboard? If I succeed in doing this and it does not work, won't the software WD says is on it to install it be gone, leaving me with a blank, unrecognised drive? You can see I have never installed a new hard drive on any computer so please be patient with me. Thanks

- After posting my question, I got through to a Wd service manager who checked everything out with me and finally suggested I tap the drive sharply on the back since a power button would sometimes stick. I did that and the button must have released since the drive then became bootable, recognizeable and has been working since. Sorry to have been such a bother for so simple a solution; I had tried to work the button but I quess it needed a slap--maybe I do too!

-   Suggest you try Disk Warrior before anything drastic. Had similar issue and after trying all else tried disk warrior. This fixed my entire disk n data loss in 10 minutes
