one of my clients has a SanDisk 2 GB USB flash drive that he uses to work on files in and out of his office. it seems that he is able to create and add data to the drive without a problem, he then goes home and is able to plug in the drive from his home pc and read and write to the drive with no problem at all. the flash drive is readable in every other machine in his office without any issue BUT when he comes back to the office, he plugs in the drive into his pc, it shows up under my computer and in disc management (healthy/active). BUT he gets the following error when he clicks on it under My Computer "ONLY PART OF THE READ PROCESS MEMORY OR WRITE PROCESS MEMORY REQUEST WAS COMPLETED" and is unable to see any folders on the drive. however, a search for a known file on the drive, shows the files which he can then click and open. this happened to 2 drives already (we replaced the drive last week with another-transfered his data and it was okay). the first drive was recently reformatted and we then transfered his recent data from the "unreadable" drive to it (on a second pc) he was able to once again read from it. helpful, but a lot of work each time he gets to the office. what can be done at his office machine to address this. i have suspicion about the home pc but have to think the problem lies with his office pc only as it is the only one having an issue reading flash drives suggestions/help??
