    semaphore timeout period has expired

    hello again...

    dang this thing is a pain!!

    new issue today, trying to save a tiny .rtf file to external USB drive, and get "semaphore timeout period has expired" message and have to save to local drive instead. also get the message if i drag and drop into the desired location.

    perhaps related to the issue i occasionally have: the machine loses connection to the external drive and either the folder shows empty (it's not!) or doesn't show as even being connected. little blue light on the drive will sometimes go out, sometimes not, but still no access...

    EDIT: i have two verbatim USB drive attached... one or the other of them will occasional disappear from This PC and when i look at device manager there is an error on that drive. i disconnect and reconnect and the drives show up and the error in device manger goes away... there doesn't seem to be any rhyme or reason as to why this happens. when it does and i try to save something to the drive, that's when i get the "semaphore timeout period has expired"

    i have tried to update drivers using windows search online and it always says i have the best drivers loaded....

    the drives have been checked for errors and windows reports none... there is still quite a bit of available space on them (80+ gigs on each) and when they are connected and live, i can access files with no problem... it just decides to seemingly drop the drive randomly...

    thanks for any help...
