You need to make sure the Drive is ATA 2,3,4,5,6 compatible. That will cover all your bases. Check with http://stores.ebay.com/www-krex-com They have Drives that will work. On the other hand if the ATA 6 does not work put it in a USB mini case and use it as a spare.I have found that some newer drives load just fine under USB but will not load as internals.
