Hi world, 

We have a big hardisk problem on our Linux 2.0.21 box (P120 32M)

Our fdisk repartition is the following

Disk /dev/hda: 16 heads, 63 sectors, 2100 cylinders
Units = cylinders of 1008 * 512 bytes

   Device Boot   Begin    Start      End   Blocks   Id  System
/dev/hda1            1        1      204   102784+  82  Linux swap
/dev/hda2          205      205      611   205128   83  Linux native
/dev/hda3          612      612     2100   750456   83  Linux native   

Disk /dev/hdc: 16 heads, 63 sectors, 1240 cylinders
Units = cylinders of 1008 * 512 bytes

   Device Boot   Begin    Start      End   Blocks   Id  System
/dev/hdc1            1        1      305   153688+   6  DOS 16-bit >=32M
/dev/hdc2          306      306     1240   471240   83  Linux native  

Linux boots on /dev/hda2
Disks are declared in the BIOS as follows 

                  Type  Size   Cyl   Head  Precom  Landz Sector Mode                
Primary Master:   User  1083   2100   16   65535   2039   63    Normal
Primary Slave:    None   0      0      0    0       0      0    
Secondary Master: User  640    1240   16   65535   1239   63    Normal
Secondary Slave   None  0      0      0    0        0     0     

Linux detects our drives as follows: 

hda: WDC AC21000H, 1033MB w/128kB Cache, LBA, CHS=2100/16/63
hdb: FX300_01, ATAPI CDROM drive
hdc: WDC AC2635F, 610MB w/64kB Cache, LBA, CHS=1240/16/63   

We have also tried to configure our system following the large IDE Howto
to fix the kernel's problem for IDE drives with over 1024 cylinders
but we have also error messages :

When checking disks with fsck, Linux generates reports like:

Can somebody explain us what is the problem? and give us a solution
to fix errors?
Are there physical damages on our hard disks?
Or is it only a hard drive configuration problem?

Thanks in advance
