A colleague of mine has a Sony notebook with a faulty one of these in it:

HTC423030F9ATD0 - Hitachi Travelstar 1.8" 30GB 4200RPM ATA/100 Slimline Hard Drive (DK13FA-30D)

It's a 1.8" drive that has the pins on the long side of the drive. Anyone know of anywhere in the UK I may be able to get a replacement? com-com list it as a 2.5" drive with no price, so i'm not convinced of their stock/accuracy.
