Ac3M,
You have my sympathies. I ended up retiring the server ( mentioned in my first post above) last year. Apparently random problems with damaged file systems on the hard drives started to turn into destroyed partitions. Server comprises Xeon E3-1245 v3 Installed on a ASUS P9D WS motherboard with an Intel C226 chipset. And a Windows 10 Pro OS. And DrivepooI. I simply could not work out what was causing the damage.
A few months ago I pulled the thing apart and removed every hard drive (apart from the boot SSD) leaving just CPU, RAM, and power supply. And put things back in one of the time to see if I could recreate the fault (s). Eventually able to show that the problem was a dodgy SATA extender card. (And just to show that sometimes the technology does work. When the server was originally set up, I installed 3 Toshiba 3 TB 3.5 inch drives in RAID 0 Running under Intel RST. Sure, the hard drives have not exactly been hammered for the last seven years. But even after being ripped out and reinstalled as part of the fault finding, they still ran like a charm.) With hindsight, it should have twigged that the SATA drives connected to the motherboard chipset were fine - it was the remaining drives that were playing up.
Have you had any more problems on your server since you replaced the cables?
Returning to my original thread of hard drive stack stuck on 0.00%. After poking around, and reading the advice above, I opened the "Disc sectors" window on one of the recalcitrant hard drives. On the left-hand side (between two drop-down boxes) is a little button. Placing a cursor over the button brings up the useful bit of information that it will "start test".
Everything worked as it should after that. When the (manually started) scan on that drive finished, it automatically went on to the next one. My problem is now solved. Best of luck sorting out yours.
Cheers,
ALH
