Pm1643a firmware

Don't think so, it has to be done with a specific tool from samsung for a cryptographic reset.

Hi everyone, got refurbished ddn ssd pm1643a and i did not suceed to make them work , tried all fw version (gxa0 , gxa2 and gxa5) and all sector sizes. The ssd still refuse to be partitioned and writted after that :’( .. someone managed to get them work??
Regards

hi, mines worked from the start, fw gxa0, i'm not sure what is different
are there two partitions on each ssd ? not sure if it makes a difference, if you need first to format/delete each partitions, and only then format the disk ?! ... maybe there is some protection that activates when trying to format the disk directly ?!

That is the question?
Had one ssd that i tried to format and did not work! And the others i deleted each partition first, then it could format.

Also, you have better chances if you try to format in command line; Maybe try these commands:

# Erase all blocks if supported
sudo blkdiscard /dev/sdX

# Low-level format (quick format: doesn't overwrite everything, just reinitializes)
sudo sg_format --format --size=512 /dev/sdX

# If you want to secure erase (can take a long time), use:
# sudo sg_format --format --size=512 --six /dev/sdX

# Reset SAS device
sudo sg_reset /dev/sdX

# Identify the drive
sudo sg_inq /dev/sdX

# List current partition table
sudo fdisk -l /dev/sdX

# Create a GPT partition table
sudo parted /dev/sdX mklabel gpt

# Create a single primary EXT4 partition
sudo parted -a opt /dev/sdX mkpart primary ext4 0% 100%

# Format the partition
sudo mkfs.ext4 /dev/sdX1

Nop it keep to refuse to be partitioned

it's was a ddn disk so it might be a lock in issue.
