How do I change the /dev/sdx number of a drive ?


Hi there,

I am running Kubuntu, and I have just wiped all my disks clean for a fresh install. However the disks don;t have /dev/sdx numbers to my liking.

I currently have the following disks this is how they appear in the BIOS under Hard Drives.

1st SATA: 250 GB - 1st SATA Master
2nd SATA: 80GB - 2nd SATA Master
3rd SATA: 320 GB - 3rd SATA master
4th SATA: 500 GB 4th SATA Master

They however appear on my computer when I try to install as

/dev/sdc = 250 GB
/dev/sdd = 80GB
/dev/sda = 320 GB
/dev/sdb = 500 GB

However I would like them to look like this.

/dev/sda = 250 GB
/dev/sdb = 80GB
/dev/sdc = 320 GB
/dev/sdd = 500 GB

Does anyone know how to accoplish this without changing the order in the BIOS ? Id like the sdx numbers to match the order in the BIOS.

Any help greatly appreciated.

Thanks
C

You would need to change the other they are plugged into the SATA controller, not the order they appear in the BIOS (Linux largely ignores the BIOS, and generates it's own hardware information).

The device nodes are designed so that they don't arbitrarily change like drive letters under Windows, so to get them to change you would need to physically move around the drives.
