U disk write protects a repair process that cannot be formatted

Basic background: A Taiwan electric 128M old u disk (no lock on the USB drive), in the toy virus, has been killed. When you plug in a computer or write something in it, "the floppy disk is write-protected and cannot be written to the floppy disk, please remove the write protection from the drive deviceharddisk1dr46." cannot be formatted, and write protection is also displayed.

　　Repair experience (difficult):

Online Search shuttle u disk low-level format tools used 3.27, 3.20, Chinese version, English version, but do not recognize this U disk. Search again Mformat, can recognize, but still can't format, error is "DEVICE error code:0x0405" (By now I have fixed the U disk, these two top name software is still the same performance). Then HP what the format software I think is basically the same as Windows itself. Then think of the Internet has seen the use of Ghost repair U disk method, after the failure of the above thought can only use this method. Then empty out of the F-disk mirror, the specific process is not to repeat, still fail, ghost have not started can not continue, is still unable to write (at this time has been quite discouraged, because this is the last way I think). Take out the system installation disk, in the selection system installed in which disk where the format U disk, write protection can not be formatted (although it is not possible to know the success, but still try the following, and indeed failed). If this is my own U-disk estimate to give up, I think it is probably a hardware problem. But it was someone else's, and just after killing the poison I already thought good, once sent back once ... This time with usboot (the U disk is the tool to start the disk), because it can recognize this U disk, almost all of its functions have been used, but only one is successful, is the HDD mode format u disk, then the U disk will be changed to local disks, but the problem of write protection is still. Power grid Station Search for this drive, not found. Under a lot of other models of repair tools or drivers, tried, did not recognize this plate, almost desperate ... Finally the RP broke out, into my computer-management-Disk Management, the U disk that disk "delete disk Partition", U disk space is gone. Plug in the U disk, in the disk Management, like the addition of a new hard drive, so incredibly let me format, oh~yeah~, after the format of the remaining 109M, has been very happy. There's a little bit of a problem, the U disk changed to the local disk (although no use of the impact), but also with usboot to simulate the ZIP disk format, did not change back to removable disk, but there is an additional gain-free space to change back to 124M.

Repair process Over

　　Useful steps in this repair process:

1. Use Usboot to format the U disk in HDD mode

2. Delete disk partition on disk Management

3, the final use of usboot to simulate the ZIP disk format

Lessons learned:

1, a variety of u disk chips are different, various repair software strengths

2, first try to use the official repair software to repair or low lattice (I am suffering from neither the CD-ROM nor download)

3, Don't lose heart ~
