Issue with flashing a BU40N

[tpglitch]

Hello guys,

I was trying to flash LibreDrive firmware onto my BU40N drive which currently runs 1.02. I was attempting to flash it to LibreDrive-patched 1.04.

The commands I tried running are:
*

Code: Select all

makemkvcon f -d 'dev_21:0' -f ./sdf.bin rawflash enc -i ./bu40nfirm.bin

*

Code: Select all

makemkvcon f -d '/dev/sr0' -f ./sdf.bin rawflash enc -i ./bu40nfirm.bin

*

Code: Select all

makemkvcon f -d '/dev/sg0' -f ./sdf.bin rawflash enc -i ./bu40nfirm.bin

- Says it could not find /dev/sg0 although the kernel recognizes it.

I double checked it's not in use. `sr_mod` is builtin to the kernel on my distro.

Also I am running the OS via a SSD over USB and the drive is directly plugged in via SATA on the PC

If it is an Archgon, they changed the PCB in their enclosure which stops flashing. The drive should be taken out of the enclosure to flash and use.

Thanks for your reply! I am aware of that change and yes it is the Archgon BU40N. I did indeed take it out of its enclosure and directly use Slimline sata.

Some adapters still don't allow flashing commands to pass through. Check the Ultimate Guide 2026 (and possibly some other threads (use the search function)) as it may have some recommendations for products known to work.

When I first got some bare BU40N drives a few years ago, I used an AC powered SATA to USB adapter along with a SATA to slim SATA adapter.
