View Full Version : [ubuntu] [SOLVED] IDE drive recognized as SCSI drive (not working) by Hardy

May 4th, 2008, 08:13 PM
Neither Hardy Live CD or hardy Heron fresh-installed let me work with the two partitions I got on my IDE drive. Notably on that IDE hard drive there is a windows partition (that was, obviously, removed from GRUB, and I had to add it manually) and an archive ext3 partition. My Ubuntu partition, the swap one and another ext3 archive partition are on the primary SATA drive.

Please note that :

1) If i boot with the option "all_generic_ide" the partitions are visible, but the general performance is compromised and I experience system lock-ups.

2) Everything worked ok with Gutsy

3) During the installation of Hardy the install program recognizes the partitions.

4) In nautilus i can't even see the two partitions on the IDE drive, but just a SCSI drive that ubuntu is unable to mount.

here's the output of "sudo fdisk -l"

sda is the IDE drive, sdb the SATA one

output of "lsb_release -rd"

Description: Ubuntu 8.04
Release: 8.04

i attached the output of "sudo lshw".

Well, today we discovered on launchpad the final solution:

the ide cable!

the new modules absolutely require a 80-wire ide cable (the one with coloured pins), everyone of us who experienced this bug had 40-wire ide-cables...

...and of course a good cable plugging (blue plug on motherboard, gray on slave and black on master) and a correct setting of the jumpers of the hard disks (disk set as master if it is connected to the black plug of the cable, ecc ecc).

A manually setting of the dma speed and pio mode in the motherboard bios is also a good idea.

Best regards.
