Thanks for your help Phoenix32 but I feel I may have misled ppl , the unit isn't a 4100 as I described but a 4000 ( has 4 drive spaces but only 1 led for disk , and it's a 2U size unit ) .
My apologies for this and thank you for the info , just in case the same applies for a 4000 I zeroed a WD 20 gig drive and put it in the IDE 1 slot as a master drive and turned it on.
After leaving the unit for 10 mins no lights came on or flashed ( network wasn't connected but I assume that won't make a difference ) so I imagine that because of this things aren't as well as they could be
Does the 4000 series have the OS on flash? , I have looked at the mobo and can't see a flash chip.
Thanks guys , Mike 8)
