Drive count problem

i’ve been recovered a 8TB dx4000 (4x 2TB) by iso recovery successfully , but after recovery the pcd displays Drive Count = 0 and network speed is too slow.

what is the issue ?

If you look in the dashboard WD tab, does it show 4 drives initializing?  May take up to 5 days to initialize/speed up/return to normal

It seems, that your Sentinel rebuilds your Array in background. Normally you can see it in the Monitorsection of your Dashboard.
