Getting an ibm as/400

I don't think there is any point on imaging AS/400 drives. The original AS/400 OS had "single level storage" so basically a the disks were an extension to ram, or more that RAM is just a temporary disk buffer. SO just as a program in virtual memory can be spread across any location of physical memory, a "file" on an AS/400 can be spread across any number of disk sectors on any drive, which is probably why RAID is common. There is a less worse explanation here:-
