    How is data stored on a USB drive?

    It may be a silly question for some, but I'd like to know:
    "How does a USB drive store data?"
    The HDD stores data magnetically, RAM stores data electronically, USB stores data ?
    Also, is the data safe from X-Ray, or magnitism or other elements?
    Regards,
    Rudi

    Since I don't have one, I probably shouldn't be responding, but perhaps this will provide a clue: Howstuffworks "How Removable Storage Works" (looks to me like it's the same as "regular" hard drives.)

    Re: How is data stored on a USB drive?

    Hi BigAl,
    Thanx for your reply. Your link does talk about USB portable drives (hard drives), and these store data magnetically. The USB drives I'm querying about is the flash disks. I have a 128MB flash disk. I have searched some pages, but still cannot find out how these store data, and what can corrupt the data on these, eg, X-ray, magnitism...etc!
    Regards,
    Rudi

    Re: How is data stored on a USB drive?

    Try here and on linked "Next page" pages...

    In your definition, the storage is more "electronic" than magnetic, and is susceptible to cosmic rays flipping bits. Possibly to high-intensity X-rays, but probably not to airport scanners...

    Good luck!

    I think they're also susceptible to nuclear blasts, orange juice, small rodents, smelly blue cheese and reality TV shows.

    But I could be wrong. <img src=/S/confused3.gif border=0 alt=confused3 width=45 height=45>

    What a combination.... <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15>

    Let me guess...you can up with this combination of items due to the fact that you were watching a reality TV show about nuclear blasts while you were feeding your small rodent the smelly blue cheese that was on your sandwich that you had as an afternoon snack with some orange juice!!!!! <img src=/S/yum.gif border=0 alt=yum width=15 height=15>

    I am intrigued by what is clearly Life As We Know It, chez Lyra J... ("How unlike the home life of our own dear Queen").

    PS Perhaps you thought I was joking about cosmic rays flipping bits...?

    No, I knew you weren't joking about cosmic rays, but thought I'd add some irreverence to this thread, just for the sake of it...

    Re: How is data stored on a USB drive?

    Mine went through the washing machine to end of cycle and still works. Moderately impresseed with that, will check pockets more thoroughly in future. Not sure how it would have gone if it did a trip through the dryer, luckily it fell out when I removed the jeans from the washing machine..

    I too managed this trick recently, it didn't even wash the data off the USB Disk!
