Third update: The offending disk just died

Second update,
How easy it is to fool oneself.
After more experimenting, I used the disk that gave me problems and installed Ubuntu 8-10 on it.
No Problem, Ubuntu sees the ide disk as a scsi disk and this works somehow.
So it must have something to do with the Lenny distro.
As a newbie that's how far I can analyse it

Hi, I have just installed Lenny, encountered a small problem...
During the first boot I get the following messages and then the boot process stops:
Aperture beyond 4GB. Ignoring
[8458569] end_request: I/O error, dev hdc, sector 0
[8458603] Buffer I/O error on device hdc, logical block 0
[8516757] ldm_validate_partition_table(): Disk read failed

I have an AMD64 X2 processor
3 disks 2 SATA, 1 IDE
2 cdrom players

Lenny is installed on the IDE drive which is the second master IDE so this should be the hdc disk.
I installed Grub on hd0
Cheers


Just an update, your replies got me thinking and experimenting.
I Switched the IDE cables, turned off SMART added irqpoll and noacpi. Nothing
I removed the other drives, Nope.
I removed the IDE drive, which is in a swap tray and put in a very old 20gb drive.
This worked, Lenny installed so easily, even easier and quicker than xp
So it's either the drive or the tray it's installed in.

It would be helpful if you could indicate whether you have other OS's on your system and if so, which you use to boot. If it is the Debian Grub, did you install Grub to the mbr of the disk which is first in boot priority?

It seems Lenny thinks your hard disk partition table is messed up.Try booting after adding the modifiers "irqpoll" & "noacpi" against the GRUB entry for Debian Lenny. Also, try disabling the SMART option from the BIOS setup of your computer.
