      I would say, that this is a more secure way, but there are usb drives which aren't made to store data. There are USB drives which could destroy your computer hardware, inserting a high voltage back into your computer.

    Why wasting a USB drive, when you know how to properly wipe it before using it ? I do the following under Linux (of course):
    1. Disable auto-mount
    2. Get the list of storage devices with "fdisk -l"
    3. Wipe clean the USB device by using the dd command at the device level. That will wipe the partition table, the data, everything.
    4. Create new partition, preferably non-FAT/NTFS, for the entire disk, using GParted.

    Even on windows, why would one have autorun turn on by default especially on usb drive?

    Last time i checked, autoplay doesnt exist anymore. If you still have autoplay, and it is enabled, you kinda deserve to get a virus. but disable that then format it. Just dont run any programs on it and you will be fine.

    What an IDIOT. He assumes that we all run windows. My missus foud loads of sticks in the hotel she works. Usually there are documents (company files or student's files). One in particular had a hidden folder caled "WORK" He had a few gigs of hardcore porn. I found that hilarious. No viruses there, that's for sure. All clean and vaccinated.

    I'll pick it up and reformat it using my office mate's personal laptop :-)

    Ubuntu will ask you before auto-opening anything (like an executable)

    I can open it safely in Linux. Then I'd poke around the files before reformatting. Yes, I'm that curious.

    Back in the late '90s and early 2000s, you wouldn't put a stray floppy disk into a floppy disk drive on a PC as it could contain a virus and some schools or businesses would prohibit you from bringing in a floppy disk for this reason. Same thing here with USBs.

    Send them to me! I have an old PC loaded with a security distro based upon Debian linux. On accessing any media it performs a scan. Reformatting a USB device is generally easy, but if it was engineered to deliver a payload it will not format properly. In that case it will be pretty obvious.

    (Do NOT try that on a Windows machine! )

    Why let good hardware go to waste!

      Of course, you and Danny are gambling that the USB drive does not contain some Linux-based malware. :-)

      ow ditto!! I'm in UK and can clean them and donate to schools / youth groups. As for linux malware? well, learn a simple command... it is called copy and compare ... sadly, cc was already in ues, so they called it dd ... now known as disk destroyer... and, it actually will do that to data when asked. If any one in UK has any and want to donate email me on phillw (at) phillw (dot) net
