Description Luis Enrique 2004-01-08 16:06:10 UTC

Distribution: Debian SID
Hardware Environment: Intel PIII 800 Mhz, with 2 IDE disks.
One disk (hda) has installed ontrack disk manager from Seagate because
my latest bios version doesn't support disk sizes > 32 GB.

Software Environment: 


Problem Description:  
At same distribution, using kernel 2.4.22 there was no problem with it, and hda
has every of his partitions.
My root is at /dev/hdb2, /dev/hdb3 is a swap, and my /home partition is at
/dev/hda5, with other swap on /dev/hda3.
When I tried to upgrade to 2.6.0, no partition in /dev/hda is seen as with
2.4.x: with older kernel, i have 5 partitions, and with 2.6 only one partition
that seems to be dm6 and it's size is disk's size.

fdisk sais that /dev/hda1 is of type 54, OntrackDM6.

Restarting with 2.4.x the filesystems still are there and with it it's information.

With hda=remap as a boot parameter I only get a disk with a bad partition table,
as fdisk sais.

As I haven't found information about this problem with linux, I think it would
be a bug.

Steps to reproduce:
Install Ontrack Disk Manager DDO in a hard disk.
Boot with kernel 2.6.0
That's all.

Try hda=remap63.

Comment 2 Luis Enrique 2004-01-13 15:49:10 UTC

Fine. No problem with remap63.
Perhaps it's better place to ask it, but...
Why this change in this new kernel version? 
Is there any benefit with this?

Thanks a lot, bzolnier.
