hey guys, i have a sony vaio tr2a, ultraportable laptop. ive had it for a few years and i think its time to change the hard drive. ive done some research and the hard drive is a Toshiba 1.8 inch PCMCIA hard drive. some sites indicate that it is a permanent hard drive, but ive also heard of ppl changing the harddrive for a new one. i cant seem to find it anywhere online, do you guys have any suggestions or thoughts? i really dont want to spend money on a whole new laptop. thanks!
