It is probably way too old,the seagate prevents windows from booting up and the WD is not detected in windows but detected by the POSThow old is the drive?
can you see if it works in other PC?
Seagate have an app you can use to test drives but if you can't even start up with it in PC, its going to be hard to test if it works. the signs would be it doesn't work, as one thing PC does at start up is check on the drives, and if drive never replies, the PC just sits there and waits. It will eventually time out but it sure could lead to slow boot times.
could check the cables too, try another data cable maybe
No,it doesn't show up in the disk management at alldoes WD show up in disk management at all?
you could try running Data lifeguard for windows and see if it can see the hdd
I think its time to buy a new pc because this one is already old and need a replacementhow old is the drive?
