Hello All, I am having a bit problem here . I asked a friend
to burn a cdrom of the RH sparc 6.1 iso image . He did so .
I can mount the image & appears I can 'find /cdrom -type f -ls'
the dir. structure without error . But several (if not all)
files if I 'cat filename >/dev/null' gives me .

cat: 'filename': I/O error

And I just found these in the dmesg output .

scsi0: MEDIUM ERROR on channel 0, id 4, lun 0, CDB: Read (10) 00 00 04 9a
74 00 00 01 00
Info fld=0x49a74, Current sr0b:00: sense key Medium Error
Additional sense indicates Unrecovered read error
CD-ROM I/O error: dev 0b:00, sector 1206736

And later on reading another file .

scsi0: MEDIUM ERROR on channel 0, id 4, lun 0, CDB: Read (10) 00 00 04 9a
09 00 00 01 00
CD-ROM I/O error: dev 0b:00, sector 1206308

Definately not a good thing .
Just wondering if anyone else may have had this happen ?
and/or If anyone may have found a way around this .

What I am hoping is that the data may actually still be there
only the timing of the cdrom drive may be off or somesuch .
Tia, JimL
