Hello guys, my hdd died yesterday, the exact same stuff like mentioned in the first post. Not recognized by bios or windows, takes long to boot with XP and the defected hdd as slave. Now I am really lost, I don't know what to do. Send it to seagate, will they get my data back? The data is extremely important. Or do I have to try something else? I am afraid of killing my hdd and i don't know what to do, please somebody point me to the right thing. Thanks The hdd is a 500GB 7200.11 with SD15 firmware. If the firmware is SD15 and you have some technical ability, you will be able to fix the drive after reading through this thread. If you don't feel safe in performing the fixes outlined here, then Seagate does offer free data recovery and firmware upgrade for this drive model. Only for that one? Mine is a ST3500320AS. I don't even know how the error is called. I'm pretty desperate, is all the stuff gone now? I emailed them but is it likely that they offer free data recovery? Oh ****...
