someone more knowledgeable than I may know the 'rest of the story': I am working on a little WD "My Passport" usb ext drive which works, except it seems to 'hang' sometimes when put to use, or runs very slowly as measured by 7's little time-estimator and kb/s or mb/s meter. When I run WD's own diags, it fails but without a real error code - in other words the test can't really run. when I try to flash the firmware, it fails... cannot complete. when I run chkdsk /r it will fly through until exactly 10% into stage 4 of 5, then simply stops. no errors or bail out, it just halts, or rather appears to be waiting on a task which never turns.
the drive inside has its own unique interface to usb port: not a conventional sata that is frontended with an adapter board so I cannot test it sans usb-interface.
anyone have a clue as to what the issue may be? its clear the drive is untrustworthy for anything serious but for occasional use, I'm trying to get it a tad more coherent
