Hi all
I have noticed that when doing cat /dev/cdrom > /dev/null on a Linux 2.2.x kernel (x=1,6), the following messages appear on the console right at the end of the CD: ATAPI device hdc: Error: Illegal request -- (Sense key=0x05) Logical block address out of range -- (asc=0x21, ascq=0x00) hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x50 end_request: I/O error, dev 16:00 (hdc), sector 300708 ATAPI device hdc: Error: Illegal request -- (Sense key=0x05) Illegal mode for this track or incompatible medium -- (asc=0x64,ascq=0x00 cat: /dev/cdrom: I/O error
Similar messages occur when using a SCSI CDROM and don't seem to be dependant on whether it is a CDR or a pressed CD being read.
This didn't seem to occur with 2.0.36 (or 2.0.30 for that matter). Is this a bug or is it just a deliberate design decision (if so, why was it done)? How can one cleanly read a CDROM image under 2.2.x (or can/should the above errors just be ignored)?
Regards jonathan
PS: please CC any replies to me as the kernel list archive i'm currently accessing may be missing some articles for some reason. Thanks. -- Jonathan Woithe email: jwoithe@physics.adelaide.edu.au www: http://physics.adelaide.edu.au/~jwoithe
