• Updated to support newer drive db versions.
  • Synology added size_gb in a recent host v7 version (in SynoOfflinePack 764).

"Storage Manager > HDD/SSD > Settings > Advanced > Update Now" then run syno_hdd_db with your preferred options.

  • Previously only supported DSM 7.2.1
• Changed to enable creating storage pools/volumes on NVMe drives in a PCIe M.2 adaptor even if PCIe M.2 adaptor not found.
  • This may allow creating NVMe volumes on 3rd party PCIe M.2 adaptors.
• Bug fix for when there's multiple expansion unit models only the last expansion unit was processed. Issue #288
• Bug fix for when there's multiple M2 adaptor card models only the last M2 card was processed.
