weird problem while recognizing dvd-rw


hi there. i have a weird problem while setting up my dvd-rw drive and here is my linux box consists of 3 hard drives, 1 DVD-RW(/dev/hdc) drive and 1 CD-RW(/dev/hdd) drive. i already double check the jumper settings.

if i remove the CD-RW drive, the DVD-RW can be detect as /dev/hdc and able to read data as usual. however, if i plugged in both the drives, only the CD-RW can be detected as /dev/hdd. here's the section from dmesg :-

Code:
Aug 23 19:29:33 lucifer-v1 kernel: hda: MAXTOR 6L040J2, ATA DISK drive
Aug 23 19:29:33 lucifer-v1 kernel: hdb: Maxtor 5T020H2, ATA DISK drive
Aug 23 19:29:33 lucifer-v1 kernel: blk: queue c03bb3e0, I/O limit 4095Mb (mask 0xffffffff)
Aug 23 19:29:33 lucifer-v1 kernel: blk: queue c03bb51c, I/O limit 4095Mb (mask 0xffffffff)
Aug 23 19:29:33 lucifer-v1 kernel: hdd: HL-DT-ST GCE-8320B, ATAPI CD/DVD-ROM drive
as you can see in bold words, i dont understand what that lines mean. by the way, i dont have this problem while in my windows xp. both the drive can be detected and use. for your information, im using slackware 10.2 with stock kernel 2.4.31. could it be kernel issues?

hi again. sorry for late reply though. i aint got time to test it out. so, i booted up my BackTrack v1.0 livecd and both the drive can be recognized correctly. this livecd is using kernel 2.6.x, as you can see from it's uname -a output :-

Code:
slax ~ # uname -a
Linux slax 2.6.15.6 #1 SMP Fri Mar 24 16:46:23 GMT 2006 i686 unknown unknown GNU/Linux
slax ~ #
and here is the output of dmesg :-

Code:
...

hda: MAXTOR 6L040J2, ATA DISK drive
hdb: Maxtor 5T020H2, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14

hdc: HL-DT-STDVD-RAM GSA-H20N, ATAPI CD/DVD-ROM drive
hdd: HL-DT-ST GCE-8320B, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
...
well, i think it is quite safe to say that it could be the kernel 2.4.31 problem. kernel 2.6.x, here i come!
