I bought an external 2tra western HDD has a USB 2.0 port .It was working fine with the USB 2.0 connection. I could copy, delete, write files onto the drive. When I used the eSATA port I get the "Disk is Write Protected" warning. and my hard's kit is broken .now i have very importent thing in my hard and i cant use it and i use another kit or hard box for use it but all of them say "Disk is Write Protected" warning
