Disk is write-protected error, what to do?

I made a thread in the memory section, but I think it is more suitable here:

This is a problem I haven't seen before. I can't copy files to USB drives. I always get the disk is write-protected message, although the flash drives I use doesn't even have write protection feature/button. It happens with all drives and in all USB ports. The flash drives are fine and work beautifully in other machines. The funny thing is that it the case with all machines in my home network ! It started with my main machine but it later spread to others.

When it first started, I used the 2nd or 3rd machine in my home network to copy files to removable media. This was a temp work round. Now, I can't even do that !

Could this be related to my router? How? I don't think it is a virus or a malware. I made sure the disks I use are fine. I also followed instructions to disable write protection found in here:

but it didn't change anything.

I disconnected one computer from the network, restarted it and tried copying but it didn't work.

Any thoughts?


Thanks in advance

Hello Iamgenis,

Here are some of my recomandation:
- scan you computer for viruses and trojans
- have you performed the following steps:
* Check for ReadOnly setting
* Open regedit and search for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies and select WriteProtect key. Right click on it, select modify and change the value to 0

Dammit. It was a sneaky virus after all. All fine now!

Thanks to all.
