Did you replace the USB cable? Is your hard drive detected within Windows Disk Management? If so, does it show your hard drive as RAW? Does it have a drive letter? Disk Management access instructions are available in the following link:

when i plug it into computer go to disk management its online D healthy primary partition when i try to open it i get D:\ is not accessible. Access is denied.
cheers for all your help

Does it list the file system (NTFS, exFAT) of the volume? If it does not, then the problem is the volume has lost the file system.
