Joining multiple disks to form one large disk: Any idea how?

[Outsider]

I'm looking at what options I have to fulfill the following requirements, in terms of storage:
- join multiple pre-formated (with the FS of my choosing) partitions (on different sized drives) into one large accessible space.
- If one drive dies, only the data on that drive is lost. All other data remains.
- If I pull one drive/parttion out, it should be accessible like a regular partition on another system. (this means that the original FS is not modified, and remains accessible when the drive is removed)

I know there's JBOD. What I 'm looking for is kinda like that, but not exactly.

Prefer if this was linux based, but will take any OS.

Check out Dynamic Volumes (Windows). I've never tried it, but maybe it will suit your needs.

Why not just map a drive/partition as a folder in linux?

JBOD lose all data if 1 disk dies.
Any level of RAID is not suitable in your case since you wanted the drives to be accessible when you pull them out and connect into another computer.

You might wanna look into Linux EVMS or Linux LVM

Edit: Havent used this before, but check out Diskpart..

Dynamic Volumes/Disks won't work, because you cannot convert them back to Basic and still be able to keep the data.
Also, Dynamic Disks = Software raid in Windows.
