i have a Toshiba Portable Hard drive. DTP 110 is the model i think. recently i copied some movie files to it from a friends usb stick and immediately after this it wouldnt open. it trys to but comes up with an error msg. what could this be?
As Mattios said, it would be really helpful if you could provide a screenshot of the error message or at least tell us what it is about.
Apart from that, you can provide some more information on how is the drive recognized by Disk Management and Device Manager.
