working.
Hard disk drive problems
1.
Remove the first drive not recognized and try the hard disk drive diagnostic test
again.
2.
If the remaining drives are recognized, replace the drive you removed with a
new one.
Not all drives are recognized by
the hard disk drive diagnostic
test (Fixed Disk test).
System stops responding during
