Can I manually move data from one hard drive out of a JBOD array to the others in order to replace it (or just leave it out of there)?

Update: It should not be so difficult right? JBOD is not like one file is spread out over multiple disks (striped), but only file A is on drive 1 and file B is on drive 2. I just need software that can read the individual drives in JBOD, then only move those files, and replace the drive (or leave it out of it totally).
