To copy is OK, To move display inproperly

WD elements portable 1GB , Win 7

Does it happen to you all also?? What to do…?

If i copy a file from/to it, everything goes well

But if i move – just cut and paste-- from/to it, it can’t display the processing rolling, the remaining time and speed and other information. To move the file still work, and takes the same time with to copy the same file, just can’t display the information, just like caculating the time, the process bar rolling from left to right again and again…

Do you guys know why? does it happen to you? i use HD tune, windows tool to test it, seems nothing wrong

Does it happens with another computer?
