I have a new (3 weeks old) WD My passport HDD 1 TB, and I use Windows 7. I run the HDD through a USB 2.0 port, since my computer doesn't have USB 3.0 ports. My mouse is connected via a USB port as well. It happens occasionally that when I try to access folders on the HDD, the mouse pointer lags and jumps in the direction I moved it to, specially if the folder have many files and folders, and when these folders change there shape according to there contents, also it sometimes happen when I check the size of a large folder.
When it happens it does when I move the pointer over an open window of this drive. I doubted the antivirus software I have (AVG) so I disabled it but still happens, maybe reduced not really sure but it happens.
Taking in consideration that the drive have shown no sign of other issues. All the WD utility tests, and data life guard tests I ran came out "Passed". The smart report is OK. But when this condition happened I began to suspect the drive. Do I have a bad drive here??
