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



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)
