Thank you everyone! It turns out that I do have a Fusion drive. Since the two drives are "fused" and working as one, only one drive shows up in the
> System Settings > About>System Report/Storage
information file and in the "Disk Utility" program. But if you run
diskutil list
in Terminal, you get the following info, which shows that I have a Fusion drive, as the Fusion drive is the synthesized drive consisting of the Physical drives disk0s2 (the 1GB HDD) and disc1s2 (the 28GB SSD).
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *1.0 TB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_APFS Container disk2 1000.0 GB disk0s2
/dev/disk1 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *28.0 GB disk1
1: EFI EFI 314.6 MB disk1s1
2: Apple_APFS Container disk2 27.7 GB disk1s2
/dev/disk2 (synthesized):
#: TYPE NAME SIZE IDENTIFIER
0: APFS Container Scheme - +1.0 TB disk2
Physical Stores disk0s2, disk1s2
1: APFS Volume Untitled00 - Data 822.1 GB disk2s1
2: APFS Volume Preboot 1.7 GB disk2s2
3: APFS Volume Recovery 1.1 GB disk2s3
4: APFS Volume Julie's iMac 8.8 GB disk2s4
5: APFS Snapshot com.apple.os.update-... 8.8 GB disk2s4s1
6: APFS Volume VM 2.1 GB disk2s6
For those still reading, I don't understand why Apple, in the Ventura system, has changed the reporting of the hard drive on the
> System Settings > General/Storage Setting
page, so that it doesn't explicitly report whether you have a Fusion drive or SSD or HDD drive (as it did in Monterey and earlier). I guess it's because all new Macs in 2022 only have SSDs, but this seems wrong not to tell a user of older Macs, the details of their equipment.
Again, thank you everyone for your help!! And I want to note the post at
https://apple.stackexchange.com/questions/450851/how-can-i-confirm-my-fusion-drive-is-working
on a similar topic that provided useful information.
