Note that doing this will erase all data on the drive. You might be able to recover the drive hardware by using a tool such as Bootice to manipulate the MBR.Īdditionally, if the drive uses a Phison controller, you may be able to use the Phison USB Mass Production Tools to reprogram the controller and restore normal operation. Drives failing in this manner will often show up as a storage device with 8MB capacity.įrom this answer: You can obtain more information about the drive and its controller using a tool called ChipGenius. It is also possible that the drive is fake and the cheap memory chip in the drive has failed. Again, from the standpoint of the computer, there is no medium in the drive to be formatted or repartitioned. To the computer, the drive is not much different than a floppy or optical drive with no disk inserted.Īs a result, it is not possible to access any data on the drive, nor is it possible to repartition or reformat the drive. This is usually caused by the NAND flash failing. Because of this, it appears to the computer as an empty disk drive. 'No Media' means the flash memory controller cannot communicate with the NAND flash memory on the drive.
