I don't fully follow the description but you can usually remove
partitions in Disk Utility and it reallocates space to other disks.
And/or you can resize disk 2 to occupy the freed-up space. I don't quite
know how you ended up with so many! See if you can reduce the number
(when you can see them all there should be + and - signs at the bottom).
Come back eg if you get it down to 2 but can't remove the last one.
cheers

Hi Jason,
I followed your advice and it worked - thanks again!
However, being unfamiliar with partitions I have got into a muddle by
trying to erase things. The operating system is now called Disk 2 and
it is 338.5 GB. 550GB is occupied by green “untitled” and 5GB is
orange “untitled” and 50 GB is red “untitled”. The (now) empty
“Mackintosh HD” is 14.21GB
You can probably clearly see how I’ve messed things up by sliding
around the pie chart!
How do I get rid of all the partitions now and let the operating
system (now called Disk2) have access to the whole drive?

Is it that you want to ensure your data is erased? You could
partition the disk, creating a small extra one and install macOS
onto that, then start up from that recovery disk and erase the other
partition....

Dear SMUGs
(Especially Sam)
I’m trying to wipe my old iMac. It has an SSD in it replacing the
original hard drive. I get to the Disk Utility, choose SanDisk
SDSSDH, give it a name, click “erase” then get the message
“erase process has failed”
Can anyone advise?
Thanks, Phil
