Do i get it right that it's a computer attached drive, not a standlone video player ? If so: By what program do you try to read from it ? If not: You are probably at the wrong place to ask. > I was also curious if there is any generic > utility that could probe the drive firmware as well? Any pointers are > appreciated. :) The computer attached drives get operated by the SCSI protocol. The sub-protocol MMC does not provide means to inspect the firmware or the drive's health directly. But possibly an inspection of the medium state by a burn program can tell how the drive presents itself via the protocol. With a medium, which is supposed to be readable, do: xorriso -scsi_log on -outdev /dev/sr0 -toc 2>&1 | tee -i /tmp/xorriso.log (assuming that you only have one drive which then is /dev/sr0). The messages will be shown and also caught in file /tmp/xorriso.log which then would be interesting to see. Expect about 100 to 200 lines of text. Send the xorriso.log to me in private so i can look for clues. I will then report to the list. Some of the SCSI commands used by xorriso will also be used by the kernel or programs which access the drive directly via SCSI/MMC. Have a nice day :) Thomas
