Sometimes I have to reset NVRAM to get internal drives to mount

Hello All,

When I starup my 7,1 Mac Pro, sometimes one of the additional internal drives won't mount without me resetting the NVRAM. It'd be either the TimeMachine 2TB HDD in the Fusion Flex J3i, the Accelsior 4M2 card in PCIE slot 3 (with 2 drives RAID 0), or the Amfeltec SQUID 4x M.2 in PCIE slot 5 (with 4 drives RAID 0). This never seems to happen with the other Accelsior 4M2 card in PCIE slot 4 (with 4 drives, no RAID). It's a mystery to me every morning as to if it will startup with all drives, or if I'll have to reset the NVRAM to get going - sometimes more than once.

Any ideas on where to begin to diagnose this?

Thanks in advance,
Paul
 
Depends did you probably unmount these drives at one time? Also look at if you have a bad cable or the drive is not blessed to boot from that drive or it has password on it!
 
No, I've never unmounted the drives, and as I've mentioned these are PCIE cards. The only cable is the one that came with the J3i which is brand new. And while those drives have had this issue- it's the rarest. None of these drives in question are used for boot purposes, and none have passwords.
 
Then look at the cables because some cables are made cheaply these days, even from so called manufacturers of externals! If they were made before 2015 were made to fail after a few years! Also if this traditionally external make sure the drive it are still good bad use most plater drives fail after 3 years these days!
 
Thanks for replying again, Satcomer. The J3i (the only thing related to this with cables) was made after the 7,1 was introduced in 2019 - but like I said fails to mount far less than the PCIE cards in this situation. For every 10 fails I'd say the J3i would account for less than 2 of those. Also, there are 3 PCIE SSD cards in the 7,1 and 1 of those never fails to mount. Happens to not be a RAID. Looking into that found threads on other forums speaking of the same problem, which according to them points to an issue with Sonoma.
