If Drive B fails, the file system’s pointers (the metadata that says "File X is located at sectors 1,000,000 to 2,000,000") are now pointing to a black hole. The operating system sees the array as "RAW" or unformatted. Standard chkdsk or fsck will not fix this; they will make it worse.
JBOD configurations are the wild west of storage. They offer maximum capacity utilization by spanning a logical volume across multiple physical drives. However, this architecture has a fatal flaw:
Unlike RAID, where you can hot-swap a failed drive and rebuild, JBOD repair is a forensic art. It requires a specialized set of software tools and methodologies. Here is the definitive guide to the tools you need to resurrect a failed JBOD. Before we discuss tools, we must understand the pathology. In a standard RAID 5, parity allows data reconstruction if one drive fails. In a JBOD (also called SPAN or BIG), data is written sequentially: Drive A fills up, then Drive B, then Drive C.
