Not sure if I am posting in the right place so please feel free to correct me if not..
A client of mine has Dell Precision T3400 with Matrix Storage Manager version 18.104.22.1682 running RAID 1 on two Seagate 1 TB drives. One of the drives failed and the PC would not boot up after that (no boot device found). I was able to go into the configuration (CTRL-I) and break the RAID and now it boots up normally provided that the good HD and the failed HD are present. If I disconnect the failed drive I get "no boot device found". I purchased another 1 TB Seagate drive (not the same model as the good one) and I still get the "no boot device" message. If I go to configuration (ctrl-i) and attempt to Create RAID volume I get "error: Not enough available space". All I am after here is to rebuild the RAID 1 by adding a new drive. What am I missing here? Any help would be greatly appreciated Also, backing up the drive and re-installing Windows is a last option as there are many pieces of software on this PC and a lot of intricate configuration (dentists office). Thanks for any help anyone can shed on this issue.
