Hi, I have updated my drives to the Seagate ironwolf pro 16tb. After initializing, adding, and rebuilding each drive I had tried transferring data from a CF card to the RAID 5 and got an Unmount error for one of the drives. I also experienced a pink flash & mac shutdown after rebuilding and trying again. I sent the drive back and just initialized a new drive and it is rebuilding now.
However, I am not seeing any indicator light on that drive, OR drive D. I can only blink the lights on A & C. I did see drive D's indicator when transferring data last night, but it no longer shows, even when all 4 drives are in and I start up I only see A & C lights.
Attaching a log from when the drive unmounted as well as a current log.
SO for me to be clear: you bought 4 drives, replaced them. One appeared defective and you replace it. (A good reason to "certify disks", even thought it will take a week on such large drives)
Your new drive appears to be working OK?
The panic log shows a time out, so it could have been a disk causing this. Lets see if your system remains stable.
Thanks for the reply! Yes that is correct. It is currently rebuilding, so I will see how it is once complete. TB4 was working fine after I removed that single drive and I was able to move data to it without issue.
Literally as I was typing my last reply, Softraid gave me a missing disk error, I hit OK and it started rebuilding again seemly at the same point it was at, no added time. I have a brand new thunderbolt 4 cable connnected 240w, switched from a working thunderbolt 3 cable when the issue happened the first time.

Perchance are the two disks (replacement and the one ejecting) next to each other, either AB, or in CD positions? You can use Blink disk light to check.
Hi, I just finished rebuilding today, everything seems fine until I transfer data onto the TB4. This time I got Disk 7 "D" unmounting, and then out of sync and rebuilding. The disk that was ejecting the first time was "B". I just tried blinking lights on all, and the only disks that will blink are A & C.
After the TB4 unmounted, I turned it off and back on, I got a magenta screen flash and kernel panic, shutting down my entire system. I have a i/0 error on disk 8? That is D but why do my disk numbers go 4,5,7,8 now?
Disks are randomly assigned disk #'s at startup.And if a volume mounts, any disk showing up later will get a higher number.
Note: Please do not post panic logs here unless asked, they are captured in the support file, which is more valuable. (I know the Apple forums encourage panic posting, that is because there is no Apple diagnostic that can capture them easily)
IO errors are any communication error, not necessarily a fault in a disk. A bad "address" will generate an error.
Is your enclosure really 7 years old? That could be the (or another) issue...starting to fail.
Yes I purchased in 2018. Would that be the cause even if it’s just showing up after swapping to new drives? Should I expect to need to buy a new enclosure every 7 years? What are my solutions now to diagnose?
If I buy a new enclosure, can I purchase it without softraid and then transfer this license to the new enclosure and go back to the free version on the old one? Can 8 just put these new drives in the new enclosure and have all my data that I transferred over?
