I have a sandisk usb drive but I can’t remove write protection I tried diskpart and registry and neither worked. can I fix it? UPDATE: I think i need to reinstall the firmware how would i do that and how to back up my existing firmware
Open it up. The rattling may be the right protect switch has come loose. Here is a software option. There are others. https://www.easeus.com/storage-media-rec… If you don’t have any important data on it just reformat. USB Drive Factory Reset Tool v3.0 is a good one. More. . . @iliketechalot You’ll have to do the leg work. Re: partition managers newer freeware versions may not have all the full capabilities of older ones. This site archives some of the previous versions http://filehippo.com/ Look around. ChipsetGenius will give you the flash drive chipset and firmware versions details - use an on board USB 2.0 port directly (not an external Hub). Here is an example output from ChipsetGenius: “Description: [I:]USB Mass Storage Device(USB3.0 FLASH DRIVE) Device Type: Mass Storage Device Protocal Version: USB 2.10 <- Hint: This device can run faster when plugged to a USB3.0 port (Note - would NOT work from my USB 3.1 ports) Current Speed: High Speed Max Current: 300mA USB Device ID: VID = 1005 PID = B128 Serial Number: 0703677A1B7B1768 Device Vendor: USB3.0 Device Name: FLASH DRIVE Device Revision: 0100 Manufacturer: USB3.0 Product Model: FLASH DRIVE Product Revision: PMAP Controller Vendor: Phison Controller Part-Number: PS2251-07(PS2307) - F/W 05.01.10 [2016-03-16] Flash ID code: 983A94937651 - Toshiba [MLC] Tools on web: http://dl.mydigit.net/special/up/phison…. " Mainly in Chinese but utility names are in English so cut and paste and do google search. So you see it gives the controller brand, part number and firmware version. Cut and paste the results into a text file for reference. This is a good site. http://www.flashdrive-repair.com/ Remember the firmware must be exact. You will have to search yourself. If you are not having fun here I would suggest dropping it and moving on. You have to have a curiosity with a passion to investigate this kind of stuff. If you do please keep me posted on your progress.
I have the same problem. Same, it is a Sandisk Cruzer USB. It happened suddenly, 1 day I decided to format and hope , enable to write, or write protected. During my research peoples, I read that it happen after using something like secure vault, or dont know what. but I never used that $@$* secure vault or dont know what provided by Sandisk. Another reseach told me that those Cruzer USB are faulty and should be sended back, they gona provide another one. Except warranty is gone + in my country no warranty disponible or Sandisk store. I tried everything, even GParted through DOS. Nothing works!! Never ever buy again a Sandisk or Cruzer product!! Luckily there is no data on it. My best guess, internal software need to be flashed back, with something through DOS, not through Windows, cause Windows is very poor for managing other devices than itself. Maybe by Linux. Unfortunatly I could not find anything over the net for this problem, most people say it is locked by the small Switch present on the USB, except there is no switch!
