# Updating a Samsung SSD (840) Firmware with Linux

If you are lucky and have an (external) CD drive you can burn one of the ISO images provided on the Samsung SSD page. However as I bought the SSD (a 840 non-pro) for my netbook and had already installed the SSD and didn't want to remove it again I didn't have this option.

After some trial and error I succeeded by extracting a part of the ISO image and putting it on the FreeDOS stick that I created using UNetbootin. Neither using the executable for Windows on FreeDOS nor creating a USB Stick using UNetbootin and the ISO image worked for me.

I read that under Windows you can create a bootable USB stick using Magican (can be found on the same download page). I didn't know this before and haven't tried it but if you have a Windows somewhere this might be a safer option than what I suggest here.

For those of you who don't want to repeat the trial and error, here is what worked for me. Updating the firmware is a dangerous procedure, your SSD could be damaged irreparably if the update fails. If you follow these instructions you do that at your own risk.

I have a Samsung 840 (non-pro) SSD but I could imagine that this could work for other Samsung SSDs, too.

## The short version

You need the samsung directory from the isolinux/btdsk.img image inside the ISO, copy it on the USB stick. Once you have booted the stick, change the directory to C:\samsung\DSRD\ directory and execute DSRDGUIO.exe.

## The long version

1. Use UNetbootin to install FreeDOS on the USB stick
2. Download the ISO image. I assume it is in /tmp/Samsung_SSD_840_DXT07B0Q.iso
3. Mount the ISO image. I've create a directory /mnt/test for this purpose:
mount -o loop /tmp/Samsung_SSD_840_DXT07B0Q.iso /mnt/test
4. Copy /mnt/test/isolinux/btdsk.img to /tmp.
5. Unmount the ISO image: umount /mnt/test
6. Mount btdsk.img: mount -o loop /tmp/btdsk.img /mnt/test
7. Copy /mnt/test/samsung on the USB stick
8. Unmount btdsk.img: umount /mnt/test
9. Reboot from the USB stick
10. Select one of the live versions of FreeDOS
11. In FreeDOS execute:
C:\
cd samsung\dsrd\
DSRDGUIO.exe
12. Follow the instructions that appear
