BTW HDD manufacturers are dropping PATA drives soon (Seagate is said to do so by the end of the year). While stocks will last for some time, and surely some manufacturers will run small batches of the PATA drives, it will soon become increasingly hard to find them. Eventually the prices will start to climb, too.
So in case you're going to buy a PATA HDD (for example amiga use), keep an eye of the availability and prices, and don't wait too long.
