Just had the same happen with us, raid 5, 3200 controlle
took the drives out to clean, as it had not been done for quite some time and we are upgrading it to w2k for a non critical server.
placed all drives back, in the correct order. switch on and for a milli second , then all lights on the drives die.
and the error message comes up eventually 1783 error and the cmd error.
Any suggestions gladly welcome
