| |
While doing a long mega-copy from one side of a DVD-RAM disc formatted with the vfat filesystem to an smbfs network share, I got lots and lots of these in the dmesg:
Buffer I/O error on device sr0, logical block 4396 lost page write due to I/O error on sr0 sr 6:0:0:0: [sr0] Result: hostbyte=0x00 driverbyte=0x08 sr 6:0:0:0: [sr0] Sense Key : 0x7 [current] sr 6:0:0:0: [sr0] <<vendor>> ASC=0x92 ASCQ=0x0ASC=0x92 ASCQ=0x0 end_request: I/O error, dev sr0, sector 17584 Buffer I/O error on device sr0, logical block 4396 lost page write due to I/O error on sr0
The DVD-RAM is detected like so (my system is an nVidia nForce 590 SLI, with kernel 2.6.22.1 and the new SCSI-using PATA/SATA drivers in use):
pata_amd 0000:00:0c.0: version 0.3.8 PCI: Setting latency timer of device 0000:00:0c.0 to 64 scsi6 : pata_amd scsi7 : pata_amd ata7: PATA max UDMA/133 cmd 0x00000000000101f0 ctl 0x00000000000103f6 bmdma 0x000000000001f400 irq 14 ata8: PATA max UDMA/133 cmd 0x0000000000010170 ctl 0x0000000000010376 bmdma 0x000000000001f408 irq 15 ata7.00: ATAPI: MATSHITADVD-RAM LF-D310, A123, max UDMA/33 ata7.00: configured for UDMA/33 ata8: port disabled. ignoring. scsi 6:0:0:0: CD-ROM MATSHITA DVD-RAM LF-D310 A123 PQ: 0 ANSI: 5 sr0: scsi3-mmc drive: 0x/0x dvd-ram cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.20 sr 6:0:0:0: Attached scsi CD-ROM sr0
Are the above errors related to media flaws, drive flaws, driver flaws, or usage flaws (i.e. "I copied $LARGE_AMOUNT from a DVD-RAM disc to a network share", "Don't do that.")?
