Hello friend, I have a Seagate external hard drive. I am having it since 20 months and it was working fine without any problem. It is 500GB Hard drive; I also have a laptop of an Acer with windows7 operating system, and I have desktop at my home with Windows 7. I used this external Seagate hard drive for data transfer from my desktop and laptop. But now I am facing a problem with my laptop. Now I can use Seagate hard drive to my desktop not in my laptop. Last week my laptop was crashed so I restarted and install the OS again. Now laptop is working fine except it is not detecting my external hard drive. Any suggestion please posts on this forum. Thanks in advance.
