I have a HP Netserver LH II, that I want too reuse to back up some smaller personal files. I want too take out the OS drives so that I have them too put back with the OS on them. I also, need too get the data off the other drives if it's important. I KNOW that the unit has a password and wondered if the drives aren't RAID in any way.I don't quite understand the question here, you will need to go into the RAID CONTROLLER and see if the drives are in an array then go from there. If the OS disks are in their own array you can remove them, if it is all ONE big array you can't. To recover files you would need to boot into some sort of live OS and copy them from there to some other safe location.

I'm also confused as to why you would want to use that to back up files - It's well over 15 years old, will be slow, ridiculously expensive to power and I'd DOUBT its reliability. You would get better speed, capacity and reliability for backing up your files from a $40 external hard drive and would make that money back in a few months due to the power savings.How will I be able too tell? Would a Hiens Disk work? If it's a hardware RAID controller you would need to boot the machine and press the appropriate key to ENTER the controller's management system. We really can't hold your hands with this, you need to get used to looking at documentation and working things out yourself. And as I said, the machine is useless so you are pretty much wasting your time doing this if you want to have useful storage on it.
