[SOLVED] USB read-only mode (64 GB DataTraveler G4)

Hello guys!
My friend has a 64 GB DataTraveler G4 (kingston) and (nobody knows how) now is setted in "read-only" mode.
I tried to format, change permissions, software for remove read-only (on Linux and Winzoz) but nothing works.

I had already created a backup, so dont need to be careful about data on the USB.
Please help 8.(

Installing pmount may help, there is an option to force read write onto the drive.

sudo apt-get install pmount

sudo pmount -w /dev/xxx

Read the man page first though, man pmount.

Done, this is the command/output

sudo pmount -w /dev/sdb

NTFS signature is missing.
Failed to mount '/dev/sdb': Invalid argument
The device '/dev/sdb' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Here the USB in gparted

^ of course, you have to mount sdb1   

pmount -w /dev/sdb1

If mounted I have the same output posted before.

If not mounted, same output but additional line at start:

Can only open '/dev/sdb' as read-only

NTFS signature is missing.

The device '/dev/sdb' doesn't seem to have a valid NTFS.

Same:

sudo hdparm -r0 /dev/sdb

/dev/sdb:
 setting readonly to 0 (off)
 readonly      =  0 (off)

But still nothing

OK, let's try opening a terminal window and running this command:

dmesg -w

Then plug the USB stick in and post any (extra) terminal output that appears afterwards, hopefully the kernel will spew out some informative error messages.

Re: [SOLVED] USB read-only mode (64 GB DataTraveler G4)

Right, can we see the output of:

sudo parted --list

(With the USB stick plugged in.)

Re: [SOLVED] USB read-only mode (64 GB DataTraveler G4)

Solved!

Probably

sudo hdparm -r0 /dev/sdb

had succesfully removed the block.

So then i used

sudo dd if=/dev/zero of=/dev/sdb bs=512

At this point was all deleted.

Opened Gparted, created a new partion table (the default selected MSDOS), created the FileSystem and all work

Thanks for support guys!

EDIT: was solved, putted the USB in a WIN PC and BOOM, it's again locked.

EDIT2: working again O:
