I heard that western digital came out with a one terabyte hard drive
i want to buy it but i read this
“Of course, we can’t help but gripe that both of these boast unorthodox 12. 5mm form factors, which dwarfs the standard 9. 5mm-height slot found in most laptops”
I cant find out whether the m1530 dell laptop can hold a 12. 5mm harddrive
anyone know? please place your sources

I can only figure out how to adjust it using the control panel on Windows. Even though there are three keys on the keyboard that look like volume controls, they don’t work. Do I need to update some software, or is it simpler than that? Thanks.

i have a dell e1505 computer and my hard drive crashed about a month ago so am looking for a new one, but i need to know if the new hard drive must be from dell also or if it can be any brand
thanks
