hi, i just got this really sweet modular hard drive for my latitude c610 latitude, but i haven't been able to format it or mount it or anything. the BIOS recognizes it, and i can see it in dmesg:


ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH3M: IDE controller at PCI slot 0000:00:1f.1
PCI: Enabling device 0000:00:1f.1 (0005 -> 0007)
ICH3M: chipset revision 1
ICH3M: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0xbfa0-0xbfa7, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0xbfa8-0xbfaf, BIOS settings: hdc:DMA, hdd:pio
hda: IC25N020ATDA04-0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hdc: HITACHI_DK23EB-40, ATA DISK drive
ide1 at 0x170-0x177,0x376 on irq 15
hda: max request size: 128KiB
hda: 39070080 sectors (20003 MB) w/1806KiB Cache, CHS=38760/16/63, UDMA(100) hda: hda1 hda2 hda3 hda4 < hda5 hda6 >

but fdisk won't see it. i've tried hdc, hdd and ide and many others just for the sake of trying, but no result so far.

i'm running debian unstable with kernel 2.6.0, help appreciated

Since on one else answered this I'll give it a shot. Isn't the line that says hdc: HITACHI_DK23EB-40, ATA DISK drive your CDROM? You only show two IDE devices hda and hdc.

Then it shows hda: 39070080 sectors (20003 MB) w/1806KiB Cache, CHS=38760/16/63, UDMA(100) hda: hda1 hda2 hda3 hda4 < hda5 hda6 > shows your stats for your first hard drive. I would think that if dmesg would show something similar to this if it recognized another hard drive.

I am not sure how modular devices are seen by Linux. I would think that it is seen as a SCSI or PCMCIA device. So have you tried fdisking /dev/sda1 or something like that?

yea... i tried every block device possible, and ended recompiling the kernel and updating my BIOS. this is what i get now:

ide0: BM-DMA at 0xbfa0-0xbfa7, BIOS settings: hda:DMA, hdb:pio

obviously the drive is not formatted, but i've tried fdisking hdc, scd0, scd1, etc.... and no luck
