i have a flash disk its 256mb but because of bad sector its is now become to 64 mb.anyone know how to clear a bad sector.

You're lucky to have 64M. I don't think that can be cleared - it doesn't have the firmware required for such. It's conceivable that you can re-write your drivers to remember that there's a bad sector somewhere, but then you wouldn't be able to have the same functionality on another machine.

bad sectors on pen drivers?
thats new for me...

 

[KillerShots]

It's conceivable. Think of it as a bad / damaged RAM chip.

 

[shahzaib]

any software to clean a bad sector.

Try a full format on it. It probebly wont reach the full 256MB again though. If the ram chip is bad then you wont be able to use it.
