The drive may be damaged. Test with a known-working drive, or test the drive directly to a PC.
The operating system on the computer may not support reading and writing to the file system on the docked hard drive or SSD.  Remember, Windows cannot read Mac or Linux file systems. Also, macOS can read but not write to NTFS drives.
If the drives came from a RAID (Redundant Array of Independent Disks), they would not be accessible in our docking stations.
If the drive uses 4Kn sectors, check the technical specifications of the docking station, and ensure it can read 4Kn drives.
