Hi,
 Receiving these error codes.  Is drive failure imminent. Can you answer if SPINRITE may fix this or chkdsk /f?

Thanks,

SKahan,

The HD521-2W indicates a SMART failure, this is the drive itself indicating it is going bad.

The HD535-2W indicates the test is encountering an error during the surface scan test.

Neither of these are a good sign.  I would back up data and replace the drive as soon as possible. Chkdsk /f may correct errors temporarily however the combination of the SMART flags being tripped and the problems reading the entire disk surface point to impending doom.
