Hello, Dave! DW>> (ncr0:4:0): "SONY SMO-C501-00E 3.02" type 0 removable SCSI 1 DW>> sd2(ncr0:4:0): Direct-Access DW>> sd2(ncr0:4:0): ILLEGAL REQUEST asc:24,0 Invalid field in CDB DW>> sd2 could not mode sense (4).

DW>> sd2(ncr0:4:0): NOT READY asc:a,0 Error log overflow DW>> sd2: could not get size DW>> 0MB (0 512 byte sectors) DW>> DW>> Since it cannot get the number of blocks (block size is wrong, too. DW>> should DW>> be 1024 bytes), I cannot use the drive at all. (or does someone know DW>> better?). Anything I could do to use the drive? DW> DW>Beats me. This is just a shot in the dark, but is it possible that the DW>parameters to newfs can be used to override the detected size? 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). Using ficticious geometry 153MB (314569 512 byte sectors)
