Failed PCB or Firmware Issues
Seagate ST9500421AS hard drive failure can result from many causes. Check out our video on identifying common hard drive failures. One of the most common causes of failure for Seagate drives is a burnt circuit board, or PCB. This can be caused by a power surge or other sudden electrical impact. If your drive does not spin up, or if you smell smoke coming from the hard drive, these can be signs of a burnt circuit board, which should be repaired as soon as possible.
Replacing a Failed PCB
If this is the issue, you can try to repair your drive by replacing the PCB. Make sure to use this donor matching guide for data recovery to increase the chances of compatibility. For instance, you should use a replacement PCB from the same model ( ST9500421AS ) and PCB revision. Also, check out the video to the right for some tips on trying to replace the circuit board. Don't want to attempt this yourself? Outsource offers a $60 hard drive Repair Service, which includes PCB replacement or repair with parts and labor!
Other Common Problems with ST9500421AS Drives
If your drive is clicking, power it down immediately! This could be a sign of a mechanical issue, such as a head crash.
Bad sectors generally signify surface damage, degrading magnetic head reading capabilities, or the end of life of the hard drive.
EPROM or NV-RAM becomes corrupt and locks out data access. The data will need to be manually adjusted and reprogrammed to the PCB.
Corruption of system area translator modules results in loss of data access and requires a “hot swap”.
