Hi. It was great, my USB flash drive. Once without transfereing anything to it. The orange light (it's pqi) went off. After replugging, windows didn't recognize. I followed your FAQ but after that windows recognized it and it was visible in "my computer". But upon double clicking a message appears telling "insert disk into drive k:\" which is the usb drive! It's no virus because it's totally inaccessible to format. ANd the PC won't start when it's plugged after restart. *** I tried to format it using the HP tool but it tells there's no media in the drive. *** I uninstalled the HUBs and Controllers...in vain. *** What is shocking me is that the "unrecognized msg" stopped and everything seems to be OK! ***Every time I plug it in and remove it my other one stops to work but works again from a different USB plug. If it's fried please tell me! Removed bold.
