Fix USB disk undetected or write protected
How many of you guys had this issue at least once? Well, I had this problem yesterday and wanted to share with you the solution for this problem.
We need to open the command prompt in elevated mode (start -> Run -> type cmd but don’t press enter, right click on the cmd and select run as administrator). We need to enter the following commands:
Diskpart
list disk
select disk and the disk number. Please note that the disk size will be shown in MB.
attributes disk clear readonly
clean
create partition primary
format fs=fat32 quick (or ntfs). For usb drives with smaller capacity it’s recommended to use fat32. If you want to make a bootable usb format as ntfs.
* wait for the format to finish (100%)
exit
not format in this process
last order replies the following :
virtual disk service error:
the media is write protected
Hi
I tried but showing this error message
Diskpart has encountered an error: the request could not be performed because of an I/o device error
See the system event log for more information.
Please help me out
every step was going smoothly untill I reached the CLEAN command. It shows “the media is write protected. please check the log blah blah…”
I had the same with an usb-stick and windows 10. The USB-Stick was formated with an bootable image (ct’ Desinfect 2016).
I tried this instruction with Windows 10 and I had this problem. I tried Windows 7 and it seems to work, but after using the usb stick with windows 10, I couldn’t access the usb-stick.
I could solve my problem after using this instruction a third time with windows 10. the clean command had the same error but this time I wait a minute and executed clean once again and miraculous the clean command was successful. Now I can access the USB-Stick…
I tried the instructions abaove. Receive the following error:
The request could not be performed I/O Device error
Open a command prompt with administrator rights and type “chkdsk X: /f” no quotes and replace X with whatever drive letter your USB has.
Cant perform Check Disk function as its Write protected…
Did you ever find a solution? I have the same message on my comd!
Type in Run window regedit and click OK
After registry editor Open Goes to the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Storage Device Policies\
In the Right Pane Double Click on Write Protect and Type in Value 1
Write Protection is A
For Remove Write Protection
Double Click on Write Protect and Type in Value 0
write protection will be Removed
Or Simply Download the Application Called USB Write Protector
For Enable and Disable USB Port its worked for me.

Hi,
First of all, I had a suddenly write protection as well on my Kingston Datatraveller G3 64 Gb.
But I used (on Window 7 64) Minitool Data Recovery first and everything was just right there so I copied some directories with valueble data to another harddrive.
Than I did some other work and another program stalled and made me restart my laptop.
So, after reboot I tried to do the same trick with Minitool but it showed nothing. I tried several other things like cloning with Macrinum Reflect but it showed no partition that was formatted, hence no data.
I surfed around and tried solution as Regedit and so on…useless.
I watched a movie and as always, the answer came to me…..Recuva….good old Recuva did the job.
At first it gave errors on non-available data and so on but I pressed several time on Scan and tada….the files became visible in Recuva but more important: in my explorer as well. Now I had the chance to copy all the rest to a save place.
Now I’m ready to clone the whole partition on the Kingston USB to another partion on another harddrive.
I have not done this while I’m wrting here but I’m pretty confident it will work since EaseUS Partition Master Home Edition recognizes the USB. Afterward I hope that the USB wil be bootable as it should or else I’ll try to fix it with a bootrepair distro found on Distrowatch,com. Works like a charm to fix Grub and MBR failures.
So, hope that this post is usefull to you, otherwise you can reach me at [email protected] for questions.
Kind regards, Peer Gynnt
