HP Proliant Windows 2003 server

I have an HP Proliant Windows 2003 server with 3 300 gig scsi drives configured with raid 1
I have one bad hard drive.  The server shows the c drive, but cannot see any other drives.  It boots, but is very slow to log in, navigate around, etc.  Unfortunately I have no replacement drive because none was ordered when the last spare drive went.  Is there any way to get the E drive back.  The E drive has all of our applications on it.  I do not understand why it does not show up.  The drives are all supposed to be mirrored and I thought the server could function even with one bad hard drive.  Anything I can do to get the data and programs to show up?

RAID1 uses 2 disks in a mirror.

Could it be the E drive was stored on the third drive?

The third drive potentially was a stand alone drive with no redundancy.

RAID5 would have retained all the data if one disk was lost.

Here is a good site showing RAID.

Good Luck.

I hope not, but I can see the E drive when I go into Computer Management, just cannot get it to open.  The whole server just freezes up.  I am getting the new drive today hopefully and I hope all will be good.  I am not sure of the RAID set up and since the server is so difficult to navigate now, I am not sure how to check it.  I  inherited this .  I thought I was told that all three drives were mirrored.

It is  raid 5.  Got the new drive.  The new drive is lit up blinking - but I still cannot see any drives when I select My Computer except the C drive.  How long does it take to copy all and should I reboot it or no?

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

A rebuild can take many hours. I really hope your data returns.

I can only suggest you sit on it for a day.

Else you can look at installing a RAID utility to see whats happening but the server is unresponsive.

The server is not unresponsive.  I can log in - it is slow - I can see the drives, but cannot open them.  I will wait

I am still waiting.  I am not sure how long this is supposed to take with 3 - 300 gig sas drives.  The server seems to be gaining a lot of it's data back, but it still is sluggish and has not restored anything on the one partition.  The first drive (which is an original drive) flashes somewhat dimmer than the other two drives that have been replaced.  I am not sure if it is ok for me to replace that first drive now after almost 28 hours of trying to recover.  

Thoughts?  I do have another new drive for this machine, but should I risk inserting without having a full recover?   I was going to wait one more day but this is a critical machine and no apps can be accessed at this point.  Day 2.5.

I can look at the Computer Management and see the C drive - healthy and can access the C drive - but when I try to access the E drive which is where all my apps are, I get an i/o error and cannot access the drive.  I have now replaced all 3 drives on this server.  What now?

I did some research and found that there was a critical update for this particular server dealing with the exact problem I was having.  I downloaded the files and managed to run them on the server and it fixed the problem. The fixes just came out in late September and I am on the alert list, but I did not receive any emails from HP of this problem.  It was a controller update to the sas drives.  After I installed the fixed, rebooted, I could see my E drive again.  I am going to
