I am trying to format a hard drive that I put in an enclosure, I have two of these drives and the other one works, but when I tried to format the other one, I get an input/output error, I have tried to format it on a windows, and linux box, the windows says it formats it but it just well doesnt, and the linux box would display an error message, dont remember it though. This is really getting on my nerves, It will just freeze the mac, and I get the spinning beach ball. Anybody know what to do? Thanks.
