I have a broken Toshiba HDD MK3265GSX and I was looking for another hdd for my laptop and I found a Toshiba MK3259GSX...
I don't know about HDD but they look like the same...
But before I buy it, I really want to make sure that It's compatible with my laptop and I know you guys can help me

...
and maybe can explain how work those compatibilities...
My laptop is a Dell Inspiron M5010 if that help with anything
Thanks in advance!
