![]() I ran the following code: sudo wipefs -a /dev/sdc Keep in mind the dd command works with gpartedlive. the drive is fine: I went into windows and with the same 'wrecked' usb drive, copied over the same file and verified that it boots up and works fine.one damages the partition, while the other makes it seem like the whole drive is unallocated. whether I chose sdc1 or sdc seems only to affect how badly the drive is wrecked.dd does write the files and filesystem, and it is readable in linux (I can open the files) but it is useless and lsblk and gparted both say there is nothing there!.Regardless of how I do it, I noticed the following: (I dropped the byte size in case that's a problem). pv Windows10.iso | sudo dd of=/dev/sdc conv=fdatasync bs=512k Then I run: lsblkĪnd make the NTFS filesystem with this command: sudo mkfs -t ntfs /dev/sdc1Īfter which, I tried running dd, but with an additional option:conv=fdatasync (which some folks say insures nothing stays in the cache and may solve this problem). That should format a new partition and change it from the default (linux) to the ntfs partition I need. I rebooted, and ran the following commands sudo umount /dev/sdc1 This was upsetting, but I decided to start off fresh. This appears to nuke the entire partition, as you can see from fdisk: my terminal output showing the command and fdisk. (which to those familiar is the same command, piped through dd, and with sdc instead). I'd read in some places that you're not supposed to output to the partition (sdc1) but to the drive (sdc), so I tried this: sudo pv Windows10.iso | sudo dd of=/dev/sdc bs=5M ![]() Gparted shows this:īy comparison, another normally working usb flash drive (i got 4) reads like this: I get a partition that seems to mount on Debian, but is otherwise unrecognized on windows and mac. When I try to create a Win10 image in the terminal, I tried this command: sudo dd if=Windows10.iso of=/dev/sdc1 bs=512k Though I can easily create a bootable Windows 10 usb with rufus, my goal is more educational: I want to understand what is going on, and what is the source of my failure, and if possible, to make it work. ![]() I've read instructions on various sites (besides here) and they all seem to be missing something. My goal is so simple, the title says it all, but every way I've tried, I've failed.
