Re: Write-protection on 16GB cruzer blade

Iposted this in another section but I will repost here.

 

I have had this happen as well on several occassions the best way to fix it (if you are on vista/7/8) is to use diskpart, it is built in to all 3 of the windows OS that I listed.



1. open a command prompt with admin rights

2. type in "diskpart" and hit the enter key (no quote marks of course) it will open a new window.

3. type in "list disk" (no quote marks)

4. I dentify the number of the disk that matches your flash drive, on the example below mine would be disk 7



DISKPART> list disk

Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 465 GB 1024 KB
Disk 1 Online 931 GB 0 B
Disk 2 Online 298 GB 0 B
Disk 3 No Media 0 B 0 B
Disk 4 No Media 0 B 0 B
Disk 5 No Media 0 B 0 B
Disk 6 No Media 0 B 0 B
Disk 7 Online 14 GB 0 B



5. type in "select disk N" (again no quotes with N being the number of your drive). be very very careful here as disk part is a powerful command line tool and assumes you know what your doing and will easily wipe out a drive you don't want it to if you select the wrong disk number. Example:



DISKPART> select disk 7

Disk 7 is now the selected disk.



6. once you confirm it has selected the right disk number; (example above, second line), type in " Clean" (no quotes), this will completly remove all partition information and set the disk up to be reformatted



7. at this point you can either create volumes/partitions and format it with diskpart or close diskpart and use your format tool of choice.

I tried with DISKPART as you said and it  does not work at all (it had an I/O issue does not specified)...
