(Awesome site, just registered!)

My CD/DVD player drive worked fine until I installed a CDRW drive.

The CD player is: hdg: _NEC DV-5800A, ATAPI CD/DVD-ROM drive

The CDRW is: hdc: SONY CD-RW CRX215E1, ATAPI CD/DVD-ROM drive


Linux (fully patched RH8) sees them both, but won't read any CD in the player drive.

I've got an IDE controller card, and the CDRW and zip drive are on one bus, and the cd drive is on the other. CD is jumpered to master.


This may help:

root@samson:~# dmesg | grep hdg

hdg: command error: status=0x51 { DriveReady SeekComplete Error }
hdg: command error: error=0x54
end_request: I/O error, dev 22:00 (hdg), sector 64


Thanks for any ideas.

Side note -- what's the best software for burning CDs on RH8?

dma problem? check hdg with these command:

hdparm /dev/hdg

and post the output

# hdparm /dev/hdg

/dev/hdg:
