Dead SATA Controller on Motherboard? Or 2 Dead Hard Drives?

A couple of nights ago I moved everything over into my new case and ever since, my two identical Maxtor 300Gb SATA drives haven't been detected in the BIOS. My 40Gb PATA is fine, as is everything else.

I've made sure the cables are seated correctly, swapped out different data cables, tried different power connectors from the PSU but no joy.:(

Am a bit gutted as one was the backup of the other..

How likely is it that:
a) the SATA controller is broken?
b) BOTH drives have died?
c) the PSU is no longer supplying power to the SATA drives...but somehow is supplying it to the PATA HDD/DVD/Motherboard?
 
Maxtor..nuff said.
Still worth trying to find out if the drives or motherboard is faulty, do you have another computer to plug the HD into?
 
maybe worth a shot but try resetting the cmos or connecting the mimimum number of parts in to see if its a psu problem. also see of you can feel the drives spinning at all.
 
You haven't got the SATA controller disabled in the BIOS, have you? If the mobo has a discrete SATA controller as well as the one built into the southbridge (this will probably be shown by different-coloured SATA ports) then make sure you try both.
 
Cheers guys, will try resetting the CMOS and barebonesing it tonight.

badbob: :( Nup. If I did, that would make things much simpler though. :) I think I'm going to get a new SATA drive if I can't figure it out tonight. If that works, then the drives are kaput and I needed to replace them anyway, if it doesn't I can be fairly sure it's the motherboard/something else and I've got even more storage...but I don't think it'll be a Maxtor...

Mattus: Prone as I am to stupid mistakes...that was the first thing I checked :) There is a third connection on the board a SATA2 one..can't remember whether I tested it though..will try tonight...
