Re: bit per bit copy! ext3

I think, however, that you should actually copy /dev/sda1, to /dev/sdba1 not /dev/sda. to /dev/sdb
If you copy /dev/sda1, you will also copy the partition table.  If your flash drives are different sizes you might end up with problems.

another solution would be, especially if you are making an intermediate copy on your hard drive, to use partimage.  Partimage will only copy the sectors on the partition that are actually in use.. thus saving both disk space and time for the copy process.

I have a flash memory stick that is formated with ext3 file system. NOw,
there is an application on it that I would like to copy to another memory
stick. I can copy it, but when I do so, that application does not work
properly (it won't start - boot problem???).  Is there a tool that can copy
an entire content from one flash stick to another? Thanks!!!

use dd

dd if=/dev/sda of=/dev/sdb


# original flash
dd if=/dev/sda of=flash_disk.img
# with second flash flugged in
dd if=flash_disk.img of=/dev/sda

They must/should be the same sizes though.
