Question Mounting SATA hard drive to Ubuntu 24.04 not part of RAID array (sdb) ?

[rwrider]

I just installed Ubuntu 24.04 LTS on a Dell T7500 workstation with a PERC hardware RAID5 array of 2TB. It also has an ATA SATA drive of 2TB. When the system boots up, the desktop shows the "extra" SATA on the desktop mounted seperately and not part of the sda drive. It seems to me this should be simple to unmount the seperate SATA drive, and remount it to the rest of the sda filesystem as a unified volume, maybe mounted to /home as a "data" folder.

I cannot get this second drive to mount to the primary drive after I unmount it. Is this because the first drive (hardware array) prevents other mounts?

sda is not a file system
sda is the first hard drive found to mount and sdb the second. in your case sdb is shown as one logical drive, because of the array.
