How much were those drives and where did you find them?
Well…I'll tell you, but I don't believe you can replicate my experience any more simply because they are not being sold in stores any longer.
I got the 320 at my local Fry's Electronics for my birthday in September 2009. It was on sale so I paid $109. Fry's is a giant West Coast electronics firm and they were still selling PATA laptop drives then.
In mid-2011 I think is when I got my wife her 250. Her PowerBook came without a HD so I went back to Frys to get her a 320 and…found nothing!
After visits to two different Best Buys in the area it became very apparent that the highest capacity I was going to find was a 250. So, I bought one at the second Best Buy for $109 (it wasn't on sale).
I have of course, visited Frys many, many times since that last in-store buy and on occasion checked to see if they might still carry PATA laptop drives. The last time I checked was maybe a year or so ago and the ONLY PATA drives they had were desktop drives.
Intell says that none of the manufactures make PATA drives anymore. Any PATA drive you find is coming out of the dwindling stock that was still on hand when the drive manufacturers stopped making them. This is why you can't find them in a store anymore. Finding them online new is getting impossible now too. Pretty soon all that we'll be able to find is refurb/remanufactured or used.
P.S. When I got my 320 it was for my old TiBook 400. I quickly discovered the 128GB barrier. I was forced to buy Intech's HiCap driver to see the full 320GB. Of course, my TiBook died (the first time) about two months after I got the drive, so the 320 went into my 1Ghz 17" PowerBook when I won my first auction on eBay in November 2009.
