Hi all, I'm having real trouble writing normal CDs on this drive. I would really appreciate some advice.
I used to be able to write CDs on this box, but recently I have made nothing except coasters. Perhaps the drive is wearing out due to age? Old media? (how long does unused media last?) I built 2.01.01a06 myself using smake on this box.

Notes: * driveropts=burnfree and driveropts=forcespeed make no difference; * It still tries to write with at least 8 speed, whatever I do, even with driveropts=forcespeed; * Accessing the drive via ATA rather than ide-scsi makes no difference. * New media makes no difference. * Media is blank generic CD-Rs, about 1 year old. * CD writer is /dev/hdd, system runs off software RAID on hda and hdc. I can change this but performance will suffer so I would rather eliminate all other options first. Running on: * Fedora Core release 2 * Linux ndiyo.int.aidworld.org 2.6.9-ck2-aidworld #1 SMP * Intel(R) Pentium(R) 4 CPU 3.00GHz, 2 GB RAM. Using "hdd=ide-scsi" kernel command line and ide-scsi driver. Thanks in advance for any help or advice!
