partition table, but there was 1 fat32 and 1 ext4 partition.Now I want read-only file system while setting up superblock to format it fat32 clean, but I get the errors.When I open GParted, it saysGParted wrote:/dev/sdb contains GPT signatures, write protect is on indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand http://askubuntu.com/questions/182849/how-do-i-format-or-partition-a-read-only-usb-drive GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table?If I click yes - it shows partitions, but creating new partition table fails, as it is read-only.If I click no - it does not show up in the device list.Here's a picture of the structure of the device.What also strange, I https://bbs.archlinux.org/viewtopic.php?id=171056 remember making 1 GiB ext4, and rest fat32. But it shows the opposite.So I tried formatting it with fdisk$ fdisk /dev/sdb o n w fdisk: cannot write disk label: Bad file descriptorI made sure they are unmountedumount: /dev/sdb1: not mounted umount: /dev/sdb2: not mountedThen I checked the filesystems. The second one appears to be read-only# fsck /dev/sdb1 fsck from util-linux 2.23.2 fsck.fat 3.0.22 (2013-07-19) /dev/sdb1: 18 files, 96978/698280 clusters# fsck /dev/sdb2 fsck from util-linux 2.23.2 e2fsck 1.42.8 (20-Jun-2013) fsck.ext4: Read-only file system while trying to open /dev/sdb2 Disk write-protected; use the -n option to do a read-only check of the device.# fsck -n /dev/sdb2 fsck from util-linux 2.23.2 e2fsck 1.42.8 (20-Jun-2013) /dev/sdb2: clean, 860/65664 files, 56633/262144 blocksTried the zero trick, but failed as well.# dd if=/dev/zero of=/dev/sdb dd: failed to open ‘/dev/sdb’: Read-only file system# dd if=/dev/zero of=/dev/sdb2 dd: failed to open ‘/dev/sdb2’: Read-only file systemTried to disable the write-protection# hdparm -r0 /dev/sdb /dev/sdb: setting readonly to 0 (off) readonly = 0 (off)After that, fdisk still fails to format.In Windows 8, it mounts only the fat32 part.diskpart can't erase partition table as well.

Or if it is missing putting some tape around the side where it used to be to make the reader think it is no longer write protected? –Anthon Jul 15 '15 at 10:58 It is a USB flash drive. –kRiZ Jul 15 '15 at 10:59 If there is no data on it, have you tried to make a partition table on it or just write something with dd if=/some/file of=/dev/sdc to see what happens? –Anthon Jul 15 '15 at 11:03 dd: failed to open '/dev/sdc': Read-only file system –kRiZ Jul 15 '15 at 11:09 There was data on it.
