Seagate st32122a . My 500gb hard disc war slowing down so i have it for replacement. Pc specs:- i3-530 processor,dh55tc chipset,3gb ddr3 ram, gt440 gpu.|||You can.... but you also need a spiffy graphics card and enough memory to hold the OS and apps. 3 gigs of memory should be enough to hold 7. You can also install it on the back up as well.|||Yes you can|||yes u can, dont worry! go for it.|||NO. It takes 16 GB of space for w-7 32bit and 20 GB for 64 bit. The st32122a has 2.11 GB of space.|||No you can't. You can install Windows 7 on an old IDE drive but not one like this that only has a capacity of 2.1GB. This drive is only just big enough for Windows 95 or 98, even XP wouldn't fit on it.
