When I try doing anything to the disk, kernel keeps reporting Input/output errors. For example when trying to mount an msdos - formatted MO, it reports: sd2(ncr0:4:0): extraneous data discarded. sd2(ncr0:4:0): COMMAND FAILED (9 0) @f084ae00. sd2(ncr0:4:0): extraneous data discarded. sd2(ncr0:4:0): COMMAND FAILED (9 0) @f084ae00. sd2(ncr0:4:0): extraneous data discarded. sd2(ncr0:4:0): COMMAND FAILED (9 0) @f084ae00. sd2(ncr0:4:0): extraneous data discarded. sd2(ncr0:4:0): COMMAND FAILED (9 0) @f084ae00. sd2(ncr0:4:0): extraneous data discarded. sd2(ncr0:4:0): COMMAND FAILED (9 0) @f084ae00. sd2: error reading primary partition table reading fsbn 0 (sd2 bn 0; cn 0 tn 0 sn 0) DW>Oh, here's a thought... Is there a disk in the drive when you get that DW>error? If not, try booting with a disk in there. I tried it, and it works. Now it recognizes at least the number of sectors. Only the sector size is still wrong: (ncr0:4:0): "SONY SMO-C501-00E 3.02" type 0 removable SCSI 1 sd2(ncr0:4:0): Direct-Access sd2(ncr0:4:0): ILLEGAL REQUEST asc:24,0 Invalid field in CDB sd2 could not mode sense (4).
