I have a 1 year old WD 2TB hard drive. It has been working just fine. I did a quick format on it and that took about 30 seconds. However when doing a slow regular format on a Dell T7500 I looked at the process bar and it was only 1 tenth complete after several hours. I took it to another new computer and started the same process. It has been at it now for 14 hours and it is about 50% done. Normal??
