Trouble detecting >2.1 gb

[flashingcurser]

From the junk pile at work I am assemblying a backup of a backup server (just a few directories).

Anyway the mobo is an asus TX97-LE (socket 7) and the drive that will not play nice is a a fujitsu 6.4 gb (model mpc3064 at).


Clues:
Acording to asus this board should handle 32 gb drives, It currently has 3 drives in it (one is a 2.5 gb and working fine). The OS is slack 10 /w 2.6.9

The bios incorrectly auto detects 2 of the drives (one being this drive)-- I have updated bios and set the drives manually in bios.

Normal drive geometry is 13410/15/63 and an alternate is 4092/16/63-- I have set these both in bios and Kernel 2.6.9 still reads 2112. If I set 13410/15/63 in bios, bios shows correct gb (4092/16/63 shows 2112)

I have set append = "hdc=various,geometry,here" in lilo, I have tried all 4 combos of append vs. bios settings with no luck.

I do get an odd looking thing in my dmesg for the ide1 (the controler the drive is on)

then a little further down:

hdc: cache flushes not supported
 /dev/ide/host0/bus1/target0/lun0: p1
libata version 1.02 loaded.

I thought (maybe wrongly) that as long bios detected something that you could append to the kernel the correct drive geometry.

Anyone have any thoughts on what to do get the other 4gb of space off of this drive?

thanks

what are you using to partition the drive

[flashingcurser]

I just checked in fdisk

Command (m for help): p

Disk /dev/hdc: 2111 MB, 2111864832 bytes
255 heads, 63 sectors/track, 256 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1               1         788     6329578+  83  Linux

Command (m for help):

Though I may have used cfdisk and wasnt paying much attention-- the disk/partition can be reformated if that solves the problem. It only has /home on it right now. The file system is reiserfs.

Is there a jumper on the drive for dos compatibility or something? I know many had such a feature for backward compatibility.

search your junk pile or get a hold of an add-in I/O card umda 33 or higher, using this instead of the onboard controler should resolve your problem

I know - not the answer you were looking for -sorry

Yes there is a setting for 4092/16/63 which in the pdf they called "special mode" -- it equals 2111 kb. I have tried it and took out append statements then added append statements for both drive geometries with the jumper set. No luck.

Any other thoughts?
