Hi ssaulino,
From your posting, I understand that you are having trouble with the error 'This drive is write protected, Remove write protection or try another device'. Below are the steps to fix it for Windows 7 platform.
1) Go to Start > and Type "cmd" (without quotes) in the run box at the bottom
2) When the Prompt Comes up type "diskpart"
This will open a new command window after a few seconds with the Diskpart program running.
4) From there you need to find out which drive volume your write protected drive is. Type "list volume" // you may need to use "list disk" if problem still persists
This will list all the drives on your computer and give them all volume numbers.
5) Next you want diskpart to set focus on the write protected drive (For Eg: If volume 5, then you have to type in "select volume 5"
6) Now diskpart is focused on the volume/disk you can check the attributes no by typing "attributes disk" and "attributes volume"
Disk is for the actual physical disk volume would be for partitions. The setting for Each can be different BE SURE TO CHECK BOTH
My particular situation was the actual DISK was Write protected so look at both Volume and Disk attributes to find out where your write protection is set. By looking at the "Read-only" setting.
Sometimes the displayed setting may be incorrect due to Caching of the attribute, so do the below on both disk and volume anyways
To remove the write-protection you then type in "attributes disk clear readonly" or if it is the volume that the attribute is set on then you can type "attributes volume clear readonly"
Recap:-
Start > Run "cmd"
type< diskpart
type< list volume (type< list disk )
type< select volume # (type< select disk #)
type< attributes volume clear readonly (type< attributes disk clear readonly)
Do post the results (if working or not)
