## Firmware upgrade procedure
### Samsung EVO 840

For the EVO 840 I downloaded the firmware for Mac, which was an ISO file.
I mounted the ISO to a local directory, copied out the *.img* file I found,
then wrote the *.img* file directly to a USB flash drive.
My USB flash drive specified as */dev/sdx*.

```
# mount Samsung_SSD_840_EVO_Series_EXT0BB6Q_Mac.iso /mnt
# dd if=/mnt/isolinux/btdsk.iso of=/dev/sdx
# sync
# umount /mnt
```

Download from <https://www.samsung.com/no/support/model/MZ-7TE500LW/#downloads>.

I rebooted the system and enabled *Legacy USB boot* in my UEFI (BIOS),
and followed the procedure. At one point, I was asked to power cycle the
disk before confirming I had done so. I pulled the power plug of the disk
and put it back in, before I confirmed with `Y`.

### Samsung EVO 850

For the EVO 850, the firmware update ISO can be directly written to a
USB flash drive.

```
# dd if=Samsung_SSD_850_EVO_EMT02B6Q_Mac.iso of=/dev/sdx
# sync
```

## Tools

To check the firmware version of my disks, I use `smartctl` from the
*smartmontools* package in Arch.

```
# smartctl /dev/sdb --info
smartctl 7.0 2018-12-30 r4883 [x86_64-linux-5.3.4-arch1-1-ARCH] (local build)
