i fried a hard drive from one of my pc's its a 250gb sata seagate drive, sometimes it works, sometimes it freezes and othertimes it jus dont want to be recognisd,
i think its fried, but jus thought id ask u guys while am here. its been sitting in a draw for a couple of months.
ran all seagate disk checks but with errors. but why does it work sometimes and others decided not to?
 
what makes you think you fried it?
I take it the warrenty is up right?
seagate retails is what 5 yrs
oem maybe 3 to 5 yrs
 
well i emailed seagate its way in the warranty but the thing is this hard drive came with a machine so wont honour the warranty there bizniches.
i fried the hard drive accidental quick swapping those in and out sata. my own fault really but i jus dont understand why it works sometimes and othertimes it doesnt.
 
check the connects from board to the internal parts of drive maybe bad contact
another words unscrew the cicuit board from the frame
lift off gently clean any contact point
some use a fine ribbon cable look close for burnt wire
 
ok well i did that unscrewed it, seagate use contact connectors so nothing wrong there.
im gunna try find the circuit board and fix it myself. thanks for the help, and btw would a non sata circuit board work on a sata hdd?
 
no sorry it will not
you can have 2 same boards with diff firmware and they will not work
the firmware updates the hidden written drive sector
and adding a board with diff firmware screws it up.
I use used drives and reflash firmware to the matching drive I am fixing
so far about 90% success
