error in fdisk/cfdisk? (part 2)
Hi! Thanks for your help!
Bob> What is your current status? Is anything already installed on

Not really, I can delete everything on the disk again.
Bob> If some things are installed that need to be saved, it would be
Bob> advisable to back them up, and start over. If you want to try to
Bob> repair this instead of replacing it, please send me a copy of the
Bob> partition tables from fdisk (including the disk geometry data that
Bob> fdisk prints at the top of the partition table) _and_ from DOS fdisk,
Bob> noting which partitions have files installed on them.
Here's a little more detail:
At startup the BIOS recognizes the size of the first drive on the primary
controller correctly (519 MB), the second drive is a CD-ROM, and the first
drive on the second primary controller is another hard-disk, the one with
the 4-fold partition. BIOS does NOT recognizes the size correctly. It says
82 MB, really it is 4.3 GB ! It has 14848 Cylinders, 9 heads, 63 sectors.
I already did as you suggested and cleared the partition table, rewrote it,
but the effect was the same.
DOS FDISK doesn't even recognize the size of the whole disk (4.3 GB) it
says 283 MB !
DOS FDISK gets confused about the CDROM and the 4th partition. Its output is:
Partition Status Type Name MB System Percentage
1 Non-DOS 64 23% # used (Linux swap)
2 A Non-DOS 1200 100% # used (Linux native)
D: 3 Pri-DOS Chip 2000 CD01 100% # empty
E: 4 Pri-DOS Test 847 FAT16 100% # empty
You see, it recognizes the sizes of the partitions correctly, but it thinks
the CDROM is the third partition and gets confused about the drive letters
D: and E: !
Here's more info:
BIOS:
=====
User Size Precomp LANDZ SECTORS MODE
82 14848 9 65535 14847 63 NORMAL
82 524 255 0 14847 63 LBA
82 7424 18 65535 14847 63 LARGE
I'm running LILO. Maybe DOS FDISK is confused because Lilo rewrote the MBR ?
Here's what cfdisk prints:
======
# Type 1st Sec LastSec Offset Length Filysystem Type Flags
1 Primary 0 130976 63 130977 Linux Swap (82) None (00)

4 Primary 6684363 8418815 0 1734453 DOS FAT 16 (big) (06) None (00)
Here's what fdisk prints:
=====

/dev/hdc4 6386687 6684363 8418815 867226+ 6 DOS 16-bit >=32M
There's the errors (I guess): 2588355 - 2322431 = 265924
6684363 - 6386687 = 297676
(v)erify gives:
Warning: partition 2 overlays partition 3.
partition 3 overlays partition 4.
60 unallocated sectors.
(x)perts, then (u) and (p)rint gives:

Many many thanks for your help ! Helmut
