You don't need to run fdisk first, since you copy an entire disk

That is, with the flash drive inserted, do a shutdown and then restart the computer again. (Many Linuxes have a 'reboot' command you can run as root. You may also have a menu item in your GUI for shutting down and/or rebooting.) During the reboot process, you'll want to check the computer's BIOS to make sure that whatever the flashdrive is plugged into (USB, I assume) is an acceptable boot device and that it is checked before your normal boot device (which, I'm assuming is your hard drive). If you don't know or are unsure about how to do settings in your BIOS, then please read up on that before changing anything. You should have gotten a manual with your computer-- or perhaps you can download the manual from the web. rosenberg:/media# fdisk -l Disk /dev/sdb: 4051 MB, 4051697664 bytes 64 heads, 32 sectors/track, 3864 cylinders, total 7913472 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00077d8f Device Boot Start End Blocks Id System /dev/sdb1 * 32 63487 31728e W95 FAT16 (LBA) You didn't have to do the step above, but it doesn't hurt anything.

Was there another command you ran prior to running the one below? If not, perhaps there's some automount script which ran in invisibly in background.

Re: Problem with flash drive
Input/output error It might be a software issue only. I don't remember the messages I got, when an USB stick was borked. A long time ago, when I formatted a new INTENSO USB stick, it gets broken. They said the controller gets broken, because I kept it connected, while turning the computer on and off *lol*, possible but unlikely, I guess nobody disconnects mouse, keyboard or printer. I got a new one and never formatted/partitioned it, now it's very old and still working. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

If your FreeDOS image is really a boot image (as the name of the file suggests), then you need to start the copy at the very beginning of the media, i.e., sector 0.
