R-Studio is a professional-grade data recovery suite designed for advanced users and data recovery technicians.
(Free/Open Source): If you are on a budget and the partition table is gone, PhotoRec can "carve" files directly from the disk sectors. It is text-based but very powerful for individual drive recovery. Critical Steps for JBOD Repair JBOD data recovery - DiskInternals

Keep three copies of data on two different media types, with one stored offsite. Critical Steps for JBOD Repair JBOD data recovery
If you suspect physical drive degradation (clicking sounds, slow response times), do not run recovery tools directly on the live disks. Download a tool like Clonezilla or use R-Studio to create a bit-stream image (.img or .bin) of each drive. You can then load these virtual disk images into your repair software, protecting the failing physical hardware from further stress. Step 3: Reconstruct the JBOD Virtually
Add the component disks to the list. Ensure they are placed in the correct chronological order in which they were originally spanned. Select the correct JBOD/Spanned volume type. Step 4: Scan and Extract Data You can then load these virtual disk images

Before attempting a software repair, you must verify that the individual physical disks are not failing. Hard Disk Sentinel : Provides preventive hardware checks
A Just a Bunch of Disks (JBOD) architecture combines multiple physical hard drives into a single logical volume. Unlike RAID configurations, standard JBOD offers no data redundancy. If one drive fails, the entire file system can collapse, making data recovery highly complex.
