I just knew this. Do not place your flash drives close to magnets and cellular/mobile phones if you want your flash drives to remain useful.
Most of us place our phones in our pockets along with the flash drives we have. Or, we place our flash drives in the same place we do our cellphones for easier search.
I just watched this on TV and found out, the magnetic field being generated by cellphones and other magnetic devices can erase data on your USB disks, or even cause your flash drives to be broken and later on, useless.
Obviously, I have nothing good in my mind to blog about. Sorry. But this sure helps, yes?
