I am trying to replace a laptop. Old one is a Toshiba MK6021GAS. the specs for it list it as a ATA-100.
the Samsung one I am insterested in listed on Newegg is ATA-6. In fact NE has NO ATA-100 hd listed. Can I get one of them ATA-6 in replacement or do I have to get the ATA-100 ones.
laptop is older Alienware 51M 5600 series with 1.8 Ghz p4

ATA-6 is basically UDMA5. Which is also called UDMA100, etc. The only difference is the fact that ATA-6 is a sixth generation spec that also supports 48bit addressing.

I am not trying to sound dumb...but then are you saying I'll be ok to buying an ATA-6 HD to replace the busted one.

EDIT : and it appears that the old HD is ATA-5......so where does that put me with me want ing to buy the ATA-6

No worries...

Yes, you should be fine even if the controller does not support 48bit addressing. Your core logic is recent and for the P4 which should easily support 48bit LBA. The only issue really is you would need at least Windows XP SP1 and a controller that does also support to create a single partition size of 137GB or greater.

I think I saw that you are looking into purchasing an 80GB drive. This is within the latter 28bit addressing limit and no need to worry anyways.
