[SOLVED] usb stick size reduced to 10 mb after dd

Hello.
I've recently updated BIOS using this tuorial. I've created custom image and made a bootable pendrive using this:

sudo dd if=freedos.img of=/dev/sdb

Now when I try to:

dd if=KaOS-2016.11-x86_64.iso of=/dev/sdb bs=4M; sync

I get:

dd: error writing '/dev/sdb': No space left on device
3+0 records in
2+0 records out
10485760 bytes (10 MB) copied, 0.0105674 s, 992 MB/s

I tried to fix it using GParted but I can't change the partition size over 10 Mb no matter what i do. It was 16Gb before that. What can I do with it?

Re: [SOLVED] usb stick size reduced to 10 mb after dd

Try:

sudo hdparm -r 0 /dev/sdb

If that doesn't change the situation, plug in the stick and post the output of:

sudo parted -l

Almost there! The full result of:

sfdisk: If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)

Re: [SOLVED] usb stick size reduced to 10 mb after dd

Has it worked then?

Do you need to wipe the MBR?

sudo dd if=/dev/zero of=/dev/sdb bs=512 count=1

Re: [SOLVED] usb stick size reduced to 10 mb after dd

For some magical reason it has worked now. I could've sword I wiped out the MBR many times using this command, testdisk and whatnot. Tt's solved. Sorry for making so many topics about very basic things. Thank you.
