First off I just want to say a massive thanks to pugwash75 and his fantastic hard drive removal tutorial. A great guide and very easy to follow.

Having successfully removed the hard drive, I am now looking for a compatible replacement. The one I have taken out is a 30GB Hitachi Travelstar Model HTC423030F9ATD0.
The one I have seen that I am hoping will be compatible is a 40 Gb Toshiba MK-4008GAH ATA-6, 4200 rpm, 2MB Cache 15 ms. Supported interface standards: ATA-2; ATA-5; ATA-3; ATA-4; ATA-6.
I dont understand the interface standards but Im guessing if the one I took out is either ATA-2; ATA-5; ATA-3; ATA-4; or ATA-6, then the Toshiba MK-4008GAH should be compatible?
Also once I do get a compatible drive, am I going to have any issues reinstalling the operating system? I know some laptops have a hidden system partition for use with a recovery cd/dvd and obviously this will not be on a new hard drive!
I should also mention this is not my laptop. I am just trying to sort it out for a friend. Any help would be greatly appreciated, thanks.
