View Full Version : Cannot format USB flash driver using Gparted
childintime
December 22nd, 2013, 07:28 PM
I cannot delete or do anything with this USB. Here is the information error in Gparted: http://i.imgur.com/bwdxpXe.png
First it was all good, I created new MS-DOS partition table, formatted it, but now it's not working. I cannot format it in windows either, it says it's write protected.
When I try to delete it using Gparted it says: Input/output error during write on /dev/sdb
Thanks for any help!

Looks similar to the issues I had trying to re-format one of my usb sticks a while back. It wouldn't format thru anything GUI.
I ended up getting it done thur the mkfs command in a terminal window. btw, iirc, you cannot have it mounted when trying to format it.

mkfs builds a linux file system? I want to format it with fat32 so I can burn Windows 8.1 iso and then install it on new pc.

did you give your application root permissions by running sudo first?

Which application? If Gparted, then yes, it always asks for password.

Did you use an old version of gparted? Partitions now always start at sector 2048, but yours is the old start of sector 63. Windows changed to using sector 2048 with Vista and gparted changed serveral years later, but at least two years ago. Required for SSD & new 4K drives, so should not make huge difference on flash drive but old gparted may not now be correct?

For fat32 the command would be
mkfs –t vfat <USB-device-mount-point>
Don't forget you may need sudo with it.
There are other options in this article

Updated all my software, when creating partition table with Gparted I get: Input/output error during write on /dev/sdb
When I run
sudo mkfs –t vfat /dev/sdb
I get:
mke2fs 1.42.8 (20-Jun-2013)
mkfs.ext2: invalid blocks 'vfat' on device '–t'

You normally format a partition, not a drive. Some do format a drive and it is like a super floppy but they does not work as it has no partitions to mount.
This will totally erase the boot loader and partition table of a device. Be absolutely sure you have your flash drive as if run on wrong device you then have erased it. Then you can create & format a new partition. Change sdX to your drive.
dd if=/dev/zero of=/dev/sdX bs=512 count=1
Powerful command, but often misused and then nicknamed "dd" Data Destroyer
http://www.linuxquestions.org/questions/linux-newbie-8/learn-the-dd-command-362506/
If you have used the dd method of copying an ISO to a flash drive the dd erase is required as the image copy of a flash drive does not create a standard partition table.

I ran that command, and it finally allowed me to create partition table, and partition the drive. Everything was great, but then I tried to burn Win 8.1 iso to flash using Winusb and again got this error:
nstallation failed !Exit code: 512

I guess I need to try different approach for burning iso.
Also now when I run your command
dd if=/dev/zero of=/dev/sdX bs=512 count=1
again to clean the drive I still can't create new partition in Gparted, strange that it's not working now even though it worked minutes ago.
Anyways, thanks a lot.

Any idea how to solve it? Now I cannot do anything with flash drive. Windows XP cannot format it, says "Unable to format drive" and above program does not do anything. That's how it looks with Gparted: http://i.imgur.com/M6WKJQI.png
I don't need to burn iso into it anymore, all I want it to simply work.

Did you change the example of sdX to your drive the second time?
Not sure what the label error is. I often assign labels to partitions with Disk Utility or Disks in new versions. What does Disk Utility show?

Of course I did. I check label via Gparted every time and change accordingly.

By chance have you tried to format the usb drive on a different computer.
Time for a new usb drive? It is Christmas time afterall......Merry Christmas.

I tried formatting in both XP and 8.1 but it says unable to format.

Either the pendrive is failing (which is rather common with such devices), or the partition table and other general information is bad. In the latter case it might help to wipe the first megabyte (not only the first 512 bytes). This can be done directly with dd as adviced by oldfred (but slightly modified),
dd if=/dev/zero of=/dev/sdX bs=1024 count=1024
or safer with mkusb according to this link

I tried that command, but still, I gparted says "File system unallocated".
When I try to create new file system it says "No partition table found on device /dev/sdb".
If I want to create new partition table (msdos) it says: "Libparted bug found! Input/output error during write on /dev/sdb"

I think you have done what is possible with gparted now. It seems that gparted cannot write to that device. But you can still see it as /dev/sdb (as read only). It is typical of a failing flash drive (it remains read-only after writing does not work. The next step is that it cannot be read either).
But the problem might also be co-operation with that particular USB port or with the computer, so try in another USB port and try in another computer, if you are able to create a partition table and make a file system ('format' it).

Tried other usb port but same. I guess I will try to somehow test it on another linux machine :)

If you use the dd procedure to create an Intaller, it does not use standard partition table like all the other methods. And then because partition table does not exist partition tools see random data or think it is corrupted.
Sometimes then just writing 0 to MBR to totally erase boot loader and partition table info works.
Do not use this if trying to recover any data from old partitions on flash drive.
Erase - Make double sure you have correct drive & partition, Change X to correct drive.
sudo fdisk -l
dd if=/dev/zero of=/dev/sdX bs=512 count=1

Alright, I've done that, and it's still the same errors as before when doing something with Gparted.

As posted before, it just may be dead. They do not last a long time and may just fail at anytime.

But it was good usb until I started reformatting with gparted. If it's indeed dead then it's only because I did something, but again, what I did is just regular gparted or Windows xp format commands, I didn't even use command line.

I have been doing such operations (with gparted, dd, etc) thousands times. They do not destroy the drive. They may destroy data by overwriting the partition table or (parts of) some partition, but the drive itself survives. As said before, pendrives have limited lifetime, and this one just happened to die while you were running these commands.
-o-
This is what I think; it is hard to be sure when I cannot run the different operations myself. We have to rely on verbal conversation, and we might misunderstand each other.

Well everything was going just fine, until I used Winusb to burn Windows 8.1 to usb (1st page I wrote this) and it gave me error:
nstallation failed !Exit code: 512
Log:

Umounting and removing '/media/winusb_target_1387819477_11222'...
Then I tried to run same command again which I run few minutes ago and it won't work anymore:
dd if=/dev/zero of=/dev/sdX bs=512 count=1
again to clean the drive I still can't create new partition in Gparted, strange that it's not working now even though it worked minutes ago.
So it seems that something happened when I was burning Windows with winusb. Either way, chances of usb completely failing right at that momen without any reason are quite slim.

Well, there is a reason, some important memory cell is probably locked (does not respond when you want to change it). This can happen after a number of changes of the state between zero and one.

If you actually used this it does not work, you have to change the sdX to your drive like sdb, sdc. But be sure to use correct drive.
dd if=/dev/zero of=/dev/sdX bs=512 count=1
