|Agreed, check your BIOS and see what the size is showing there. If the drive is showing 1GB then your board might not support 2GB drives. Check your online manual and while you are at it, check to see if there is a BIOS update that LISTS specifically that it is for larger than 1GB drives. If it does not support it and there is no update that is specifically for that, do not risk just a BIOS update without that confirmation, just see if you can return the 2GB drive and purchase two 1GB drives or just get the one 1GB drive and wait for the prices to go down before purchasing the second one.|
I do not know if an add on SATA card would support the 2GB drive if your BIOS does not, but someone else here might know, or you can ask one of the card manufacturers.
You have to be a little bit crazy to keep you from going insane.
