/dev/hda problem with samsung hd

[pacho baratta]

i'm working with a disk (samsung sv1022d) that my system cannot see. i
have a live cd with kernel 2.4.20 and glibc-2.2.5.

now when i boot i find in dmesg:

hda samsung sv1022d my100 ata disk drive
hda: task_no_data_intr 0x51 {DriveRady SeekComplete Error}
hda: task_no_data_intr 0x04 {DriveStatusError}
hda: 1 sectors (0 mb) w/480KiB Cache CHS=1240/255/63

....

hda : hda : bad access : block 0 count 2
end request I/O error dev 03:030 (hda) sector 0


so i tried parted, this is the response:
/dev/hda disk label not recognized
the operating system think the geometry on dev/hda is 0/255/63

and doesn't give me acess to the disk.

same for fdisk:
it simply prints: impossible to read /dev/hda.

hdparm -iv /dev/hda says:
multcount	0 off
i/o_support		0	
unmaskirq	0
dma_supprt		1
keepsettings		0
readahead		8
readonly		0
geometry		1240/255/63 sectors 1 start 0

disk samsung v1022d my100
drive conform to ata-atapi-4


so i inserted my redhat sysadmin cd.
by that (it a kernel 2.4.14) i have access to the disk, fix the label by
parted, rebuild the partitions but when i reboot with lfs i see
everything as before. 
simply lfs system has not access to the disk

well i tried to change setting in bios and put CHS=1240/255/63 with same
results.

ideas?

I fixed this some time ago, the patch is in 2.4.21-rc kernels. So please
try 2.4.21-rc2 and see if it works.

Can you try kernel >= 2.4.21-pre7 (latest is 2.4.21-rc2) ?
It contains fix for some Samsung drives which don't abort unknown
commands.
