Basically had terrible performance on my 2x1,5TB and 1x1TB, support recommended i did a clean sweep, so spent 2 days (oh dear god yes it does take that long to transfer), then a reset. The soft reset didnt actually reset, and the drobo got all confused and kept restarting and spooling the drives infinitely until i removed all the drives or finally doing a hard reset.
Now finally doing the format in progress bit, but its taking HOURS. I remember first time it did literally take 2 minutes? Would the drive having random data on cause this, and how long am I looking at?
