Amazon.com: Solid State Drive MZ9LQ256HBJD-00BD1 Compatible Replacement Spare Part for Samsung PM991 MZ-9LQ256C 256GB M.2 2230 NVMe PCIe Gen3 x4 SSD : Electronics
I tried the Samsung PM991 hack and it didn't work. Validate drive before I cut. Cut past the chips like other posters. Now drive only shows up as 1.1gb and won't format. Not sure why it didn't work like the others : r/SteamDeck
