Enterprise SSD Showing 0B in size

My suspicion is they're one of the models of SAS drive with a fatal firmware bug.

Have seen mention of that a few times in my hunting for cheap sas ssds on Ebay. Some models with firmware bugs that once they hit ~32k or ~72k hours of runtime which just die on the spot after tripping an internal counter.

Most of them are mentioned in the same breathe as "here's the firmware to fix that: (etc)", but it seems like if the drive hits the magic mark before the firmware is upgraded then it's as good as dead.

Though I kind of wonder if someone with electronics skill could flash the firmware chip directly (ie prom burner) and get them functional again.

They were all connected to supermicro servers, my server did have a failed powersupply but the other 2 servers that had 6 drives each did not have failed power supplies. There were 7 drives total in both machines and both machines had 6 drives effected. It is very strange and I am unable to come up with an explanation on what happened to the drives because they were working just fine right before the reboot.

Edit: Also there are battery backups between the power outlet in the wall and the servers.

I'm curious if you ever found a fix for the Toshiba drives. I have 16 of those drives that are all now showing a size of 0B. So far Toshiba/Kioxia support has been a dead end.
