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. <div class="gmail_quote">On Tue, Dec 2, 2008 at 5:55 AM, Justin Piszcz <<a href="mailto:jpiszcz@lucidpixels.com">jpiszcz@lucidpixels.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div><div></div><div class="Wj3C7c"> On Tue, 2 Dec 2008, milos rovcanin wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> 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!!! </blockquote> </div></div> use dd dd if=/dev/sda of=/dev/sdb or # 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.
