hard disk nomenclature
I have P5GC-MX motherboard which has on one IDE hdd slot and two SATA HDD slots. I have installed primary IDE DVD drive, secondary IDE IDE HDD 80GB and Primarty SATA 160GB SATA HDD. BIOS shows as FIRST IDEMASTER DVD FIRST IDE SLAVE80GB IDE DRIVE THIRD IDE PRIMARY MASTER 160 GB SATA HDD Debain ETCH shows 80GB IDE Drive as hdb and 160 GB SATA drive as sda. KUBUNTU 0710 shows 80GB IDE Drive as sda and 160 GB SATA drive as sdb. I would like to be enlightened why this happens. -- L.V.Gandhi http://lvgandhi.tripod.com/ linux user No.205042

Hey, As of Ubuntu 7.04 they have a unified their disks as sdX for both IDE and SATA which is why the 80GB IDE drive is now showing up as a sdX device. As to which becomes sda and which is sdb that is now AFAIK considered to be 'luck' as Ubuntu is moving towards parallel detection which does not guarantee detection order. This is possible as they now use UUIDs to identify all the filesystems: i.e. instead of '/dev/sda' it would be more like UUID=b1f711c3-e86b-4d63-a14f-ec2e2f377a12. IIRC Grub has recently added support for UUIDs too which helps removes reliance on BIOS' disk ordering also. Ubuntu is based on Debian but is a much faster moving distribution. Debian Etch is now several years old and being a stable release no major changes like this would be pushed into it. I haven't looked into it as yet, but If Debian follows the same path then at the very least these changes will not appear until a future release (lenny, sid, squeeze, etc). Hope that helps, Cheers, Owen. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Sounds like it's just changes implemented after etch in Lenny that Ubuntu is using. Lenny has all my hard drives listed as sdX and 7.10 was almost 6 months after the initial Etch release.

My mistake... younger than I thought... The point still stands: it is an evolutionary change which is post Etch. cheers, Owen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
