I'm running into a problem formatting a Tandon TM262 MFM disk drive with an Adaptec ACB-4000 SCSI->MFM controller. After issuing the normal SCSI Mode Select and Format Unit, the controller starts formatting the drive. I can hear the drive being stepped across the cylinders as formatting proceeds. After a while (maybe 30 seconds or so) Format Unit returns error status 02 00. A subsequent Mode Sense returns 14 00 5C A3, which is a SCSI 'Record Not Found' error according to the controller reference manual. The manual elaborates, "Logical block ID not on accessed tracks, but no ID CRC error". How can this error be returned on a formatting operation, which I expect to be writing the ID fields it's talking about? Also, does the 00 5C A3 have any significance? The controller manual says it's not a valid block number unless the first bit of the Mode Sense response is set (i.e., 94 for first byte). Maybe it has some other relevant meaning here? Thanks for any assistance by e-mail or posting, ..mark -- Mark_Geisert@L66A.LADC.Bull.COM Bull HN Information Systems Inc If this were an official statement from Bull, Los Angeles Development Center the From: header wouldn't contain my name. 5250 W Century Blvd - 2nd Floor "I'm shiftless when I'm idle" -- Replacements Los Angeles, CA 90045
