NEED HELP ERASING HD beta 10.15.5

[Taz Mangus]

Still not right. That's what happens when I try to erase the HD

Try click in APPLE SSD, click on the Partition button. Select each entry in the pie chart and select ‘-‘ button. Once all deleted try doing an Erase on APPLE SSD.

diskutil apfs <verb> with no options will provide help on that verb





stevenrandolph@Stevens-Air ~ % diskutil apfs deletevolume


Usage: diskutil apfs deleteVolume <apfsVolumeDisk>


where <apfsVolumeDisk> = APFS Volume DiskIdentifier


Remove the given APFS Volume from its APFS Container, losing all of its data.


Ownership of the affected disks is required.


Example: diskutil apfs deleteVolume disk5s1


stevenrandolph@Stevens-Air ~ % diskutil apfs erasevolume


Usage: diskutil apfs eraseVolume <apfsVolumeDisk> -name <newName>


[-passprompt | -passphrase <passphrase> | -stdinpassphrase]


[-passphraseHint <passHint>]


[-role <roles>]


[-group[With] | -sibling <apfsVolumeDisk>]


where <apfsVolumeDisk> = APFS Volume DiskIdentifier


<newName> = Required replacement volume name


<passphrase> = Passphrase if encryption desired


<passHint> = some string that can be shown even while locked


<roles> = "0" or one or more of B|R|V|I|T|S|D|U|N|E|X|H|L|C|Y|G


<apfsVolumeDisk> = another APFS Volume in the same Container


Erase the contents of the given APFS Volume, losing all of its data. Unlike


deleteVolume, the APFS Volume is not removed from its APFS Container. The "new"


APFS Volume will inherit case-sensitivity or not status, but not any other


attributes. If you supply a passphrase, it will (re)appear as encrypted, with


an initial user of the "Disk" user; otherwise, it will not be encrypted.


Ownership of the affected disks is required.


Example: diskutil apfs eraseVolume disk5s1 -name Bar

@justabrake That doesn't look right. I've updated my previous post with more information and I think that the advice by @Taz Mangus is a very good bet on a succesful erase.

 

[Taz Mangus]

I am surprised that doing an Erase on the APPLE SSD device does not work.

diskutil apfs deletecontainer disk0


You must specify either an APFS Container Reference or Physical Store

What happens if you select APPLE SSD device and then press on Erase button?

EDIT: Try Erasing Container disk1.

 

[allan.nyholm]

this is what you have to look for - this is my Internal HDD - could just be an SSD - so take a look at the disk identifiers there. Try using disk1 or disk0s2 instead.

it doesn't let you erase it stays unlighted where you can't use it

The Apple support doc for erasing a disk was posted already in Post #5. OP said it did not help.

I don't see anywhere that you tried this while booted to Internet recovery - different from the recovery system.
Reboot, with Option-Command-R. You will see a spinning globe, not an Apple icon during boot. Try the HD erase when booted to that internet recovery. Remember to choose "Show all devices", so you can pick the Apple SSD from the Erase tab.

I think that worked it let me erase the Apple ssd now I’m installing on the untitled

Post #14 and #15 already tried internet recovery.

Post #14 and #15 already tried internet recovery.

Yes but it didn’t tell me to look at viewer for all devices

 

[Taz Mangus]

Still surprised not able to erase in recovery mode. Unless the beta created a recovery partition that acts differently then the normal recovery partition.

There were a lot of issues with the beta a couple of times a few things wouldn’t work and took them two weeks to send out a fix

 

[LuisN]

Boot from internet recovery or from usb installer. Open disk utility and in "View" select "View all devices". Select the top most and erase it.

Maybe you can try erasing it MBR + HFS+ first, then erase it again with GUID + APFS ?

 

[justabrake]

There's definitely some hardware issue with this mac air it doesn't completely erase the HD it can't find my iphone in itunes all my screen icons that I downloaded still show up after an erase, I even erased all settings on my iphone to see if this mac would recognize it it doesn't anymore, As soon as apple opens up it's stores i'll bring it in and have them look at it
So thanks for all the help !
I'll report back and let you know what they say is the problem

 

[justabrake]

So this is a known issue it seems, found this tutorial on youtube

one person said this >
I had to take mine into a shop. They told me there is a problem with some mac hardrives that lock you out when you try to reset it. He had to take my hard drive out and manually reset it. Hope any of this makes sense, I don’t know much about computers

 

[justabrake]

I just bought a 16" macbook and it comes up with the same erase process fail

 

[Taz Mangus]

That does not seem good. I had to reinstall my computer with 10.15.4. I did a clean install and erased the drive using Disk Utility. No issues with erasing and I did it multiple times without a single error.

I would give Apple support a call and arrange to have the computer returned.

EDIT: I am wondering if what you are seeing is related to the T2 chip security. Maybe you need to disable SIP before you will be able to erase the drive. Just a thought and I could be off base here.

 

[justabrake]

I bought a new SSD yesterday(AURA SSD 240GB) and removed my macbook air SSD and replaced it came up with the same issue
what is SIP ?

Sorry, but there is no problem and there is no fail.
You try to erase your system which you are currently running and booted in. How should it work? You need to boot into the recovery partition or the internet restore.

but it’s not possible that you delete the system which you are currently running.

 

[justabrake]

How do I do that

You need to boot into the recovery partition or the internet restore.

How do I do that ?
