Are UATA (ultra ATA) drives compatible with regular ATA/IDE? I'm wondering if a Vaio VGN-T370P, which claims to use 8mm UATA, will accept a 9.5mm ATA. Thanks.

Will performance be affected if I have to set an Ultra ATA/100 disc drive to a slower speed in order to maintain compatibility with my system?
Changing the transfer mode affects only the external transfer rate of the device. If an Ultra ATA/100 device is configured for a slower transfer mode, its maximum speed will of course be limited to the maximum burst transfer rate of that mode. However, the internal performance is not affected by the external transfer mode, therefore the sustained transfer rate will not be as drastically affected as the maximum (burst) transfer rate.

More of a problem here is will a 9.5 mm drive fit in your HD enclosure. Some laptops are made with enclosures to fit all sizes while others are made to fit only one size.

Yeah, I was essentially wondering if a) it was backwards compatible and b) if it would fit size-wise. Since I don't have the computer in front of me, I was wondering if anyone actually knew or knew how to find out. I'm not sure where to check. Any ideas?
