Hi, I've got a flash drive with some document from my collegue few days ago. When I plugged the flash drive for the first time everything went well. I did what I needed and then ejected and unplugged the drive. After few hours when I connected it again Windows did not show anything and after few minutes it showed a disc with an grey icon and impossible to use or explore.
So far there are three flash drives I've tested. Kingston DataTraveler 4GB, brand new A-DATA 16GB and GOODRAM 16GB. All three are working perfectly fine on an older pc with Windows XP and on a laptop with Windows 7 32-bit. On my pc A-DATA is the one taking long time to appear and then working fine (shown and possible to explore) and GOODRAM is the same case. Kingston appears only with a grey icon after probably same amount of time and it's not possible to work with. In the disk management A-DATA and GOODRAM are shown normally. Kingston is shown but without the memory information. It shows G: as a letter of a drive but there is "no medium" sign.
It does not matter whether I connect the flash drives to both usb ports in the front panel or any from the rear panel.
I've been using the GOODRAM mainly in the past and it worked without any problem. The flash drive was shown immediately I connected it to the pc. Then there could have been a month I haven't used any flash drive because I somehow didn't need to. And then those problems started to appear. Meanwhile I've installed pretty old webcamera which was actually not working with the Windows 7 drivers so I made it work with drivers for Windows Vista. Could this be the source of the problems? But still..I've uninstalled all the drivers for the webcam already.
Other devices are working fine. Even external hard drive is working well.
It's possible to use the disc again if I uninstall all the drivers for it in the device manager, then it's connected as a new one but everything happens again if plugging again the second time.
I've also tried uninstalling all the drivers for devices which had been used sometimes in the past through the USBDeview software and also uninstalling all the usb drivers for the motherboard and then updating the drivers for chipset..but didn't bring any help :/
I'm running Windows 7 64-bit and having Gigabyte GA-H55M-UD2H motherboard.
Does anyone have an idea where the problem could be? Thanks a lot for any hints..
