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?

  • I'm confused: the devices have a hardware switch, and you want to know if the physical switch controls a hardware or software-level write-protection trigger? It would seem obvious that it's a hardware-level switch .... – schroeder Jul 21 '17 at 7:49
  • Well you know, SD cards also have switches, but those can be overwritten by software methods – Jay Wise Jul 21 '17 at 8:04
  • @JayWise no, I do not know - can you provide a source for the claim? – schroeder Jul 21 '17 at 9:17
  • @schroeder There is something I must miss in your answer, as the SD-Cards "read-only" switch is widely covered even here, on Security.SE (for instance Is the SD card write protection hard-wired or optional?) – WhiteWinterWolf Jul 21 '17 at 10:15
