I am using the WD My Book World Edition 1TB as a transfer drive for data between geographically distant computers.
In both copying data to the My Book from a 64bit Vista OS and trying to copy data from My Book to a 64bit Windows 7 OS I keep getting problems where the copy stalls. In Windows 7 I get an error message of 0x80070016.
For instance, when trying to transfer a 2GB file from the My Book to Win 7, it will initially transfer at nearly 10MB/s, then pause and an error:
'An unexpected error is keeping you from copying the file. I fyou continue to receive this error, you can use the error code to search for help with this problem.
Error 0x80070016: The device does not recognize the command.’
When I press ‘try again’ the error message ‘Invalid file handle’ is shown.
When I press the ‘try again’ then the speed drops to 3MB/s and again fails to complete to copy after about 0.4Gb has been transferred.
It has been able to transfer files of this size in the past but with difficulties.
Smaller files are able to be transferred, but I haven’t determined the size limit.
Also when transferring large numbers of small files it stalls during the copy.
