Hi scsi@freebsd people,
cc "Dirk Froemberg" <dirk@FreeBSD.org> (MAINTAINER= for ports/sysutils/cdrtools) (Dirk, please feel free to forward to Joerg Schilling if appropriate).
With
standard FreeBSD 4.4-RELEASE & GENERIC kernel &
standard port for Cdrecord 1.10 (i386-unknown-freebsd4.4)
& with just 3 things on scsi bus:
ahc0: <Adaptec 2940A Ultra SCSI adapter> port 0xe800-0xe8ff mem 0xfebff000-0xfeb
fffff irq 11 at device 18.0 on pci0
aic7860: Ultra Single Channel A, SCSI Id=7, 3/255 SCBs
cd0 at ahc0 bus 0 target 3 lun 0
cd0: <YAMAHA CRW4260 1.0h> Removable CD-ROM SCSI-2 device
cd0: 3.300MB/s transfers
cd1 at ahc0 bus 0 target 4 lun 0
cd1: <TEAC CD-ROM CD-532S 1.0A> Removable CD-ROM SCSI-2 device
cd1: 10.000MB/s transfers (10.000MHz, offset 15)
& with no activity on cd1 device, just using cd0,
I see the following error:
-----

I have done an md5 of the resultant burnt cdrom, & it contains an exact copy
of what's on hard disk, so the cd burn (to a cd-r media, not a cd-rw)
worked OK, but the message is worrying.
The drive reports 3.300MB/s but my controller only goes down to 5,
I was writing at double speed, a cdrom reported as:
Manuf. index: 13
Manufacturer: Multi Media Masters & Machinary SA
Anything else I should state ? What code in FreeBSD &/or cdrecord
should be changed to avoid this misleading non- error ?
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

Should we just add another error to the manual as another error to ignore ?
