What code in FreeBSD &/or cdrecord > should be changed to avoid this misleading non- error ? I don't know that I'd call it a non-error. My suggestion would be to send mail to cdwrite@other.debian.org and inquire about the error. Joerg Schilling monitors that list, and it's possible that other folks there have seen the above error before as well. > PS I see the note in manual: > -------- > The following message is not an error: > Track 01: Total bytes read/written: 2048/2048 (1 sectors). > cdrecord: I/O error. flush cache: scsi sendcmd: no error > CDB: 35 00 00 00 00 00 00 00 00 00 > status: 0x2 (CHECK CONDITION) > Sense Bytes: F0 00 05 80 00 00 27 0A 00 00 00 00 B5 00 00 00 00 00 > Sense Key: 0x5 Illegal Request, Segment 0 > Sense Code: 0xB5 Qual 0x00 (dummy data blocks added) Fru 0x0 > Sense flags: Blk -2147483609 (valid) > cmd finished after 0.002s timeout 40s > ------- > Should we just add another error to the manual as another error to ignore ? I don't think so. The error you got is a hardware error, the above error is an illegal request. The former implies a problem with the hardware, the later seems to be mostly informational. (And is the result of something done by the software.) Ken -- Kenneth Merry ken@kdm.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
