I have been using an Attache 512MB flash/jump drive for a while with my computer, my lap top, and PCs at school. This was gifted to me after my last jump drive was broken beyond repair by my school's computer settings, so I have only used it in our school library (instead of the computer lab) which doesn't have crazy security. So, naturally, when the tool that does our computer networking found out, he upped the settings in the library, and after I tried to use my jump drive at school today it seems to only half-work. It works in my lap top (where I made a back up of its contents) but not on my home computer. When I plug it into a USB port (I have tried two, and both ports are working fine) the PC gives me an error message saying that a device has been plugged in but it doesn't recognize the device. When I click the message for help, the great advice I get is to reinsert the device, and then replace it if that doesnt work. So if anyone has any idea how to fix this, I will be much obliged.
