Can i get a new hard drive for my A105-S2194?
Yep..you can get a new hard drive. You need to know what type, though. "SATA" or the older (and more expensive now) "IDE" type interface. It can get more involved such as size (GBs), RPM speed (5400...7200) and ultimately how much $$ you can afford. Generally, you can upgrade for around $50-60 and up.
