Resolved Unable to format a flash drive

I have a SanDisk USB 32GB usb flash drive. Today its performance has been wild. Sometime the drive letter doesn't show up; sometime I can't delete a file even the drive is showing. I restart the desktop a few times, and it has no change.

The drive has a management software "RunSanDiskSecureAccess_Win.exe" with it.

I found that it is FAT32 type thus I think that maybe I need to format it. So I did something using "diskpart" command in Win 7. See the image attached.

Then I checked the event log files. There are two errors.
Error one:

Event ID:      1005
Task Category: (100)
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      hui-PC
Description:
Windows cannot access the file  for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program RunSanDiskSecureAccess_Win.exe because of this error.

Program: RunSanDiskSecureAccess_Win.exe
File: 

The error value is listed in the Additional Data section.
User Action
1. Open the file again. This situation might be a temporary problem that corrects itself when the program runs again.
2. If the file still cannot be accessed and
	- It is on the network, your network administrator should verify that there is not a problem with the network and that the server can be contacted.
	- It is on a removable disk, for example, a floppy disk or CD-ROM, verify that the disk is fully inserted into the computer.
3. Check and repair the file system by running CHKDSK. To run CHKDSK, click Start, click Run, type CMD, and then click OK. At the command prompt, type CHKDSK /F, and then press ENTER.
4. If the problem persists, restore the file from a backup copy.
5. Determine whether other files on the same disk can be opened. If not, the disk might be damaged. If it is a hard disk, contact your administrator or computer hardware vendor for further assistance.

Thank you.

 

Hi, have a look at this link from Scandisk: Formatting a memory card, flash drive or device using a PC

Have you tried another USB connector or tried to Format in another comp? Neil.

 

Have you tried going into my computer then right clicking on the drive and select "format" from the context menu?

 

More details....
It happened when I plugged a Sony Camcorder and a Sony software was running. By some articles online, the Sony software is conflicting with SanDisk. So I made a system restore, now it can show up in Windows explorer. But it is still not working properly.

Ex: right click the folder the delete command doesn't show.
clear readonly attribute failed.

See the image please.

 

Have you had a look at the link I Posted?
Have you followed/tried what Sandisk recommended? Neil.

 

@Neil, I did. But reformatted it failed. See the image.

 

Maybe this will help with the write protected status...

I read all threads. They all have the common solution--- "RETURN IT! ".

 

I was thinking the same thing. Sandisk must've gotten hold of a bad batch of drives.
