heh, you call it low-level format? At most it is wiping the thing. As well often after wiping you need to tell fdisk the heads, cyls and sectors as reported by fdisk before wiping to have the same space to the byte.
pls send flash memeory low level format software
i want to download low lvel format to format my memory card. please help me
I want low level format for sd memory card
This is _not_ a low level format, and in fact is probably a good way to put an sd card into a state where it _needs_ to be low level formatted to recover the performance loss incurred by forcing every subsequent write to read and rewrite an entire erasure block.
For further explanation, see http://en.wikipedia.org/wiki/NAND_flash#Block_erasure
