>> would another ata drive work with my computer << yes, BUT... :
if your laptop is ann older one, the bios can have limitations for the disk size, eg the 48-bit LBA option; this is necessary for recognising disk sizes over 128 GB.
So - tell us : what is the old disk size ? and what size do you want to install ? and what model of PC do you have ?
in short :
-if your old disk is bigger than 128 Gb, you can use all sizes
-if you use the same disk size, or up to 120 Gb, it should be ok
-if the old disk is smaller than 128, and you want one over 128 Gb, you need to check first !
ATA normally means PATA. The term ATA comes from before there was SATA and PATA and at that point all drives where PATA or SCSI.
Pretty Safe bet the driove is a PATA. You have pictures above, so if yoy look you will know for sure.
As far as Bios limitations are concerned, get whatever drive is in the correct price range. Sometimes a 500 GB is less costly than a 40GB depending on supply and demand. If the bios can only handle 128 GB, the drive regardless of its size will only come up as 128GB.
2. You can look at the Bios post when you first turn on the machine in some cases.
3. You can use system info software like: http://www.holin.com/cindex.html
Also, PATA drives have a very wide cable. SATA drived use a very small connector SATA cables are usually Red, Blue, or Black.
Good luck.
