Hello,

Im struggling. Breakdown:

Got my ds923+ over a year ago. My reasoning was to use the WD nvme for containers and vms etc (vol2) for speed, keeping data in my 2-HDD shr vol1. I learned about the compatibility issue and found your fix. (Note: I also have a ssd vol 3 and nvme vol 1 cache in m.2 slot 2)

Initially I had a problem with restarting and the WD would be missing sometimes. This seemed to be config issue with the compatibility startup task I made, and haven't had a problem since correcting it.

Recently I've wanted to add a 3rd HDD to vol 1, so today I deleted vol 3 and removed the sdd to free up a bay. Didnt touch vol1 or vol2. I inserted the new HDD and on startup the WD nvme is missing. I tried to reapply your fix, update it and reapply. Different things, and its not working. I tried reseating, testing in slot 2. I cant tell that its being detected by the nas at all. Fearing the drive my have died I connected it in an old laptop, and it is detected in the bios.

I could really use some help. AI assistance has been bleak. Very much appreciated.

Drive is detectable and accessible on other devices just not in the synology nas (in either m.2 slot).

I gave up and rebuilt everything to the HDD volume.
