By crash you mean physically broken right? There is no way you can reuse a physically broken HDD. But I encourage you open it up to have a look. The platter are pretty cool shiny looking disk and the magnets in there, they are strong one.
no just the system part of the drive. just would not boot. so I got a bigger hd but want to retrive data from old drive but don't know the setting of the pins to make it a slave.
