I recently used Diskpart to setup a bootable USB stick. However when I used ASSIGN, I didn't include a drive letter, and Diskpart ended up hanging. I killed the process, but Windows 7 refuses to assign a drive letter to the device. Under Device Manager\Portable Devices, it shows the WPD FileSystem Volume Driver with a warning icon on top of it, and looking under Properties would show that the device could not be started. I used GParted in Linux to reformat my drive once as NTFS, and the second time as FAT32, and it still wouldn't be detected.
I've performed this procedure twice in the past before I saw people using ASSIGN with a drive letter. The first time my USB stick was detected by Windows after a few attempts of unmounting/remounting the drive, and disabling/enabling the driver. No such luck this time.
Anyone know how I can fix this?
