I have a problem dealing with a system set up RAID 5 with 8 hard drives, hard driver 1st Damaged

I have a problem dealing with a system set up RAID 5 with 8 hard drives, 320Gb each.  Has a hard drive (1st) that has been damaged by a drop and impact and cannot be repaired with the PC3000.  7 hard drives good.  I have collected images of these 7 hard drives in E01 format.  Here can you help me find a method to get data from 7 hard drives, missing one hard drive with Raid 5 setting?  I tried to bring in R-Studio to re-install Raid, x-way forensics but it failed and reported an unknow file system error.  Any comments I would like to thank.

My PC3000 version is not the version Raid edition.
