The Solution to this is above, but it will require a little digging. For those who want the digging done for them, here's the TL'DR. - This thread is what I used to find the answer (it's a link to another thread which you can get to in the thread posted above) - This page with the actual solution. Ultimately once I confirmed there was protection, this was the only thing i needed to do... sg_format --format --fmtpinfo=0 /dev/sda where /sda is the name of the disk you want to format. There was a lot of talk about sg3 tools etc, but i didnt need those in the end. One tip ... Formatting these drives takes a long, long time. Im not familiar enough to know how to see the status of the format if you start it in an Unraid terminal from the web interface and then close that terminal, so i'd recommend doing the format on the actual bare metal linux terminal when you start the machine.

I was trying this once more and checking logs as it happened. This section seems to be the error: Nov 26 19:26:42 odyssey kernel: protection error, dev sdf, sector 0 op 0x0:(READ) flags 0x80700 phys_seg 4 prio class 0 Nov 26 19:26:42 odyssey kernel: mpt3sas_cm0: log_info(0x3112043b): originator(PL), code(0x12), sub_code(0x043b) Nov 26 19:26:42 odyssey kernel: sd 1:0:4:0: [sdf] tag#2758 UNKNOWN(0x2003) Result: hostbyte=0x05 driverbyte=DRIVER_OK cmd_age=0s Nov 26 19:26:42 odyssey kernel: sd 1:0:4:0: [sdf] tag#2758 Sense Key : 0x5 [current] Nov 26 19:26:42 odyssey kernel: sd 1:0:4:0: [sdf] tag#2758 ASC=0x10 ASCQ=0x3 Nov 26 19:26:42 odyssey kernel: sd 1:0:4:0: [sdf] tag#2758 CDB: opcode=0x7f, sa=0x9 Nov 26 19:26:42 odyssey kernel: sd 1:0:4:0: [sdf] tag#2758 CDB[00]: 7f 00 00 00 00 00 00 18 00 09 20 00 00 00 00 00 Nov 26 19:26:42 odyssey kernel: sd 1:0:4:0: [sdf] tag#2758 CDB[10]: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 Nov 26 19:26:42 odyssey kernel: protection error, dev sdf, sector 0 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0 Nov 26 19:26:42 odyssey kernel: Buffer I/O error on dev sdf, logical block 0, async page read Nov 26 19:26:42 odyssey emhttpd: error: ckmbr, 2291: Input/output error (5): read: /dev/sdf Nov 26 19:26:42 odyssey emhttpd: ckmbr error: -1

Hi everyone. I'm brand new to Unraid (seriously, I just got a supermicro CSE-846 and got it running unraid 20 minutes ago). I also have 3 14TB Seagate Exos drives, 4-4TB drives and an SSD I want to use for cache. The strange thing is, when i try to mount any of the 14TB drives as a parity drive or as drives in the array, the page refreshes like it was successful, but then the drive disappears. If i reboot the system it shows back up. I did some searching in this forum and it seems like i'm having the same problem as this post, only I (am ashamed to admit) i dont really how to hook these up to onboard stata ports when I want to put them in the hot-swappable bays. Is there another path to troubleshoot this that lets me take advantage of these drives? I did see in other posts that tools --> Diagnostics are helpful, so attaching mine. Thanks everyone for help in advance. odyssey-diagnostics-20221126-2122.zip
