RAID 5 Data Recovery

HP PROLIANT 370 RAID 5:

I am using an HP ProLiant 370 server which has been set up with a RAID 5 array. There are 5 hard drives in the array, all of them connected to this RAID. I used them mainly for saving work from my home business. This has worked well for a while, but now there is a problem with the drives not showing up on the computer, and not displaying the data that is on there. The computer has sent a message, saying ‘Drive array failure’ when the server is booted to the OS. I have tried removing the drives and testing them individually, and there are three drives, actually the first three in the sequence, which are apparently ‘OK’. The last two in the sequence have a notice by them which is saying ‘replacement’, I assume this means that a replacement is needed for this portion of the system. I thought that I could take out the bad drives and replace them with new ones, but the system is not rebuilding the array as I expected. I am concerned that much of the data on the server will be lost, and I don’t want that, and am worried that making any more changes could make the problem worse.

HP PROLIANT 350 SERVER RAID 5:

I need help with an HP ProLiant which is in the 350 G5 server series. The server contains 5 drives configured into a RAID 5 array. I am suffering a problem which means that the server will not boot up into the computer. I get an error which says 1776, single-ended enclosure or device attached. When I have tried to test the system, it is clear that the computer thinks that the array is a SCSI, but in fact I don’t have any drives in my server using that particular code. The RAID 5 controller which I am using will only support devices and enclosures which operate on LVD. Since I don’t understand what the matter is, I have disabled the controller for the moment in order to prevent it from writing over the data while I try to find a resolution. I have a lot of data stored on the drive, and some of it relates to a conference which I will be attending soon. I need that data as part of a company display, and can’t go without it.
