Hi all,

I'm looking to replace my hard disk, which is a Seagate Barracuda 7200.11 ST3500320AS 500GB.

My friend told me to get a SATA HDD, not a SATA-II. What is the difference between the two? And is my old HDD a SATA or SATA-II?

The new HDD I'm looking at is a Seagate 7200.12 ST3500418AS, which the store assistant told me is a SATA-II. However, the Seagate website labels both as SATA only.

I'm afraid that I'll buy a HDD which is incompatible with my system, especially since I'm going to install Windows 7 on it and I previously had the problem of Windows (Vista) setup not recognizing my hard drive. Would the new HDD be compatible?

Thank you.

Regards, Rayne
