Reinstalled Catalina OS on a External Hard Drive. I had it partitioned with Mojave on my "Macintosh HD" - So how do I erase or remove the partition I had set up for Catalina.
Is there a way to "reclaim"the old partition space?
The total system seems to be working better by my isolation of the two OS's - It became so slow over time. Thanks in advance. jn

if you formatted using AFPS then select all the Catalina volumes and select - this will delete the volume so save your data first.

Thanks very much for your reply, Don H.
What does the "select -" mean? Is the dash an option or am I re-partitioning over the Catalina partitions? jn
Duh!!!!
Went to Disk Utility and "noticed" the minus sign - Mission Accomplished, thanks again. jn
if you don't do it then use Disk Utility to erase the volume and you reinstall Catalina or Big Sur you'll end up with TWO data volumes. Not good.
