I have a 500GB Passport Essential SE.
Lets give an example. I will copy a 500MB file over. It starts out fast then just seems to stop. Sometimes it will show its transferng at 50MB/S or most times it shows 6 or less KB/S Or even if it starts at 50MB/S it drops to 11,5,3, after about a minute. It often times gets to where it says there is only 30MB or LESS to transfer with 5 seconds left. And I will sit another 15 minutes or more waiting for it to fnish those 30MB…
2 PC’s. Windows 7 x64. WD drive completely updated to latest firmware. I’ve tried multipe USB ports on each PC I ca’t figure out what the issue is. I hate using this thing.
