Hi, > Drive type : vendor 'HP' product 'DVD-ROM 305' revision '1.01'
No listing of profiles ? (The GET CONFIGURATION command appears first in MMC-2 together with the first mentioning of DVD. So a DVD drive should know it.) It's probably a Pioneer DVD-305 drive. cdrdao lists it as as exception from "MMC compliant" drives needing the "plextor" driver and not "generic-mmc". http://cdrdao.sourceforge.net/drives.html So it might really be too old for telling MMC profiles. > http://h30499.www3.hp.com/t5/HP-9000/DVD-ROM-305-supports-which-types-of-DVD/td-p/3506773#.VAbTnESKnZ8 > "I've had issues with the HP DVD-ROM reading CD-RW and CD-R discs." This might indicate a systematic problem or just be some deterioration of an individual DVD drive. Because the drive is quite surely old old and possibly worn-off, it might be worth for Jawahar Panchal to try different media. DVD+RW or DVD-RW would be no waste. CD-R would be wasteful but also give hope for better physical readability than CD-RW. Helge: Since you have a drive, you can make own read tests. I have googled for LIF and HP booting. (I actually operated storage devices with this no-hierarchy filesystem of HP in the 1980s.) http://www.hp9845.net/9845/projects/hpdir/ Your README confirms that the PALO boot block is indeed supposed to bear the LIF magic number 0x80 0x00. So if the firmware complains about the lack of this magic, it is probably unable to read the first block with these two bytes from the CD-RW. This block is not used by mounting. The first two bytes could just be inquired by: dd if=/dev/cdrom bs=2 count=1 | od -c which should yield 1+0 records in 1+0 records out 2 bytes (2 B) copied, 0.0105 s, 0.2 kB/s 0000000 200 \0 0000002 If this does not yield "0000000 200 \0", then it should report some i/o error.
