Why two I appear to have two drives following the Catalina update?
I erased the disc and installed fresh yet this is what appears in disk utility.
Anyone?
Thanks
iMac 27" 5K, macOS 10.15
That's normal. The Mac HD - Data volume is where your files and apps are kept and you have access to them just like the older system volumes.
The Macintosh HD volume is where the system and system support files are kept and the user has no access to them. It's part of the new security that Catalina brings to the table.
What version of Catalina are you running? I have Version 10.15 (19A602) and only the -Data volume is shown in the Finder or in the Storage section of About this Mac but both are shown in Disk Utility.
See the Apple Recommended post at the top of this page.
and these instructions to undo the partitioning:https://support.apple.com/en-us/HT208496
I have the same problem. There are two Data discs. I can't back it up until I rename one of the discs.
No. They both show they have data on them.
I clicked on Mount, nothing happened...what next?
One is a read-only volume with the OS. The other is read/write for a user data.
I don't think so. I think there is an issue... please see my other response with images.
thanks
I restored data after installing the OS after formatting the drive.
They clearly show up to me as separate drives, am I reading the picture wrong?
thanks,
Gordon
Super confused by the "two" drives also. Going to do a clean re-install for other issues (bootcamp assistant failures (so many)) but not sure how the dual drives complicates their erasure.
Thanks H.W. So it turns out that I actually was showing 2 Data drives. One was empty. So at the Apple store, we looked at it, and deleted the extra data drive that was empty and it all seems ok.
If any good can come from your experience it would be a lesson for all of us to remember to manually back up then to back up that back up❗️
I would suggest, then, that Apple could have prevented a lot of confusion had they not made that Macintosh HD visible to users❗️
Yep, they both seem to have differing amounts of data. If possible, I'd take it to Apple store or Apple certified repair shop. Looks like there is a glitch in Catalina.
There’s no risk, it’s just that you will be wasting some storage space.
When you install Mac OS on the new drive it will partition it correctly.
If you install Catalina on the drive the installer will partition it correctly. And if you then restore a Time Machine backup to the drive it should put it in the data partition.
Macintosh HD and Macintosh HD Data?
