Question: disk utility entries

maybe someone can clarify this?...

I have 2 internal hard drives, same brand and size, I'm on 10.13.3 and Disk Utility shows this:

User uploaded file

I understand that the first entry is the drive itself, and the second is the partition, but why do I see it? Or, if I must see it... why doesn't the "Media Drive" have a similar entry?


For the record, I would like to switch to APFS, but the conversion fails with error -69860.

Also for the record, when I upgraded to 10.13 I did it with the option to keep the old file system.

Logic Pro X, macOS Sierra (10.12.6)

thanks for the advice, John... yes, I'm morbidly curious, besides, they're SSDs, so they should convert, unless the computer remembers my initial decision to install 10.13 without converting to apfs, and now it's taking its revenge :-)

The macOS installer will recognize storage devices eligible for APFS conversion and automatically convert them with no user intervention required. If it did not recognize your device as eligible, then there is a reason. Most likely, it does not recognize that device as eligible, or cannot update its firmware, or both.


Apple has absolutely no interest in testing macOS installers on any hardware they do not incorporate in the products they sell. That has caused a lot of misery for those making unapproved hardware modifications, so if you choose to do that you're on your own.

hi John, yes, that's exactly why I am posting in this user forum and not calling Apple on the phone. If you want to know, this is a 17" macbook pro that they stop manufacturing back in 2011, I need every inch of the screen, and with the SSD's, it runs, I think, as fast as a new mac. Bottom line, it's not a big deal, and probably not worth the time of everybody involved here (mine included)

I'm a little in trouble :( but: the first looks an unformatted hd (physical volume). The second (Macintosh HD) is your startup disk (logical volume) and the third... another logical volume. 3 hds and not 2?

A more skilled pal may help you.

neither. When I first installed 10.13, when it came out, it converted the ssds to apfs, then I realized that my other computers in the network can't see that, running older os', so I erased, reformatted and reinstalled 10.13 from the command line with the option not to convert. Now i'm ready for 10.13 and apfs... but apparently this one isn't :-)

I don't know how to install H Sierra on HFS+ via terminal but I did it booting from an external clone, erased the first and last 100 sectors of the destination HD (a feature of SoftRaid) and then I got the HFS+ option in Disk Utility->Erase. So if you don't have SoftRaid I can't help.

thank you... don't waste too much time on this...:-) I can always erase and start fresh.

for the record, here is the command line I used:


/Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/startosinstall --converttoapfs NO
