[comp.sys.att] Hard Disk formatting error on UNIXPC

todd@ivucsb.sba.ca.us (Todd Day) (01/14/91)

My dad recenctly had to reformat his hard drive after
it crashed.  When he tried, he got the following error:

Winchester: Error during disk format: Response = 4

Any clues as to what error 4 is?

You are seeing the (hex) contents of the error register of the
disk controller chip:

Bit 7:	Bad Block Detect
Bit 6:	CRC Error
Bit 5:	Not used
Bit 4:	ID not found
Bit 3:	Not used
Bit 2:	Aborted command
Bit 1:	Track zero error
Bit 0:	Data address mark not found

So response = 4 means Aborted command, and response = 10 would
mean ID not found.
