chewitt,
it looks to me, that the D4-320 works like a USB->SATA adapter with SATA port multiplier or something like that. Not as the "usual" JBOD volumes of simple software raid adapters. Maybe Gar90 should look for kernel messages regarding the USB devices first?lsusb
lsblk
dmesg | egrep -i "usb|ata|seagate"
I’m afraid but i’m a very beginner, how can I check this?
