Hi there and welcome
Whats the make and model of the computer?
to be honest, I don't know. I'm not sure how to find out, and i think some of the hardware may not match exactly what you would expect, as i bought it refurbished from a local computer shop.
Ok, then its going to be Sata, so any Sata drive up to 1TB will safely work in the computer.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
