Jupiter,

You asked:

"So if I want a HD for the Yamaha 9000 - all I have to do is ask the computer shop/dealer or whoever -....for a 2.5 Laptop drive ..right?"

Well, I already posted before you aked (not just any 2.5" IDE laptop drives, but the ones with less than 12.7 mm in height, and preferrably close to 8 GB in size so you don't waste your money on extra GBs):

"Yamaha PSR9000 uses 2.5 inch IDE drives (laptop drives). The largest disk size that PSR9000 recognizes is 8 GB, with maximum partition size of 2 GB. For example, if you install a 12 GB disk in PSR9000, you will only be able to format it to 4 partitions of 2 GB each. The disk should not be thicker than 12.7 mm to be installed in PSR9000. Most of the current laptop drives are either 9.5 mm or 12.5 mm and thus most of them can be installed inside the PSR9000. In U.S., an average 12 GB 2.5" IDE drive is about US$150 - US$200."

Did I post in such a way that you did not understand what I was talking about the specifics of the 2.5" laptop drive for PSR9000?
