Please run the following commands and post the console session:

$ cat /etc/debian_version

$ uname -a


Boot the Debian 9 or 10 installer, run the following commands, and post 
the console session:

# smartctl -i /dev/sda

# smartctl -i /dev/sdb

# smartctl -i /dev/sdc

# smartctl -i /dev/sdd


Mark your cables with labels and serial numbers, and keep track of your 
patching configurations.


The suggestions of re-patching and checking dmesg are valid.  I would 
connect the system drive to each port in turn, bootint the installer 
rescue shell, checking, booting the system drive, checking, and 
comparing results.  I would then put the system drive on the first port 
and try the problem drive on the remaining ports, both with the 
installer rescue shell and with your system drive.


Have you checked your drives recently using the manufacturer diagnostics 
utility?
