MS-DOS >1GB SCSI bug? Hard disk killer

Post by Andrew Richar » Thu, 10 Oct 1996 04:00:00



I've just had a hard disk killed by the ms-dos file system.

I'm running kernel 2.0.0 and the disk is a 1.87GB SCSI. With,

Disk /dev/sda: 255 heads, 63 sectors, 244 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot   Begin    Start      End   Blocks   Id  System
/dev/sda1            1        1      244  1959898+   6  DOS 16-bit >=32M

Whenever I write more than 1GB to the disk (as an ms-dos file system) it
seems to wrap around to the beginning of the disk and consequently
corrupt the file system.

Is this a known bug? Is there a patch? Am I doing something wrong?

More info
=========

- Blank disk
- Write X's to a BIG file (1024MB)
- dd the first 10k off the raw disk and you get X's
- filesystem stuffed

Win95 writes more that 1GB without problems.

Help!

When I installed Slackware3.1 with 2.0.0 it could not identify my harddisk
correctly (it could under 1.2.8, weird!), and when I tried a "fdisk -l" I
could see that there were some serious problems with my Quantum 1080MB IDE.
Solution: add a "hda=2112,16,63 hda=noprobe" to your LILO and/or bootdisk.

Of course you have to modify my parameters to suit your drive.
Hope this works.
