I found a bunch of old USB MP3 players that are knockoffs of the iPod Nano.
They have no logos on them. Some of them have a hold switch and on the computer it appears to offer write protection and read-only function.
I want to know how strong are those write protection switches. Are they truly hardware read only protection? I want to use those USB MP3 players to store antivirus softwares and clean computers.
How do I check if they are hardware or software write protection? Is there some commands I can use to try to disable the write protection and see if it works?
