So, would a serial number starting with K6… indicate a drive manufactured in June 2019?OneDay wrote: Tue May 12, 2026 3:43 amLooks like manufacturing date of April 2021.skyrider wrote: Mon May 11, 2026 11:32 pm Have you ever come across an Asus BW‑16D1H‑U Pro with a serial number starting with M4…?
I'm wondering what's inside that unit.
If the BW-16D1H-U follows the same pattern as the BW-1601X-U then it should have a Pioneer inside.
Do you happen to know whether LG or Pioneer drives were being installed in 2019?
6=June
Pioneer or LG? Maybe a LG BH50N
Usually if the Month code is 1-4 it's a Pioneer and anything after that its a LG. I've also read someone had a Pioneer drive with month December.
Honestly all drives i bought have been from 2024 to now.
If we could get members to post their manufacture date with what type of drive they have it could help eliminate the guessing.
Just wanted to add if your buying from someone on ebay you could ask them to show the sled ejected and if it has Asus on the sled front panel it is a LG.
