External disks issues on MacOS 13.5.2 (22G91)

Hello all,

I have an issue while reading or erasing external hard drives on my MacBook Pro M1, 2020, issues I don't have on my older MacBook Pro:

Old:

New:

Here is an example of a disk I can open, read, write, execute and erase on the old Mac when I cannot do anything on the "recent" one:

On the new Mac when I see it on the side panel but i cannot open it. I get this:

And when I try to erase it from disk utilities I get that:

I also tried to format it from the terminal following the well known instructions but it failed also...

And again it happens with 3 different disks (all quite old but again they are working fine on the old Mac)

So I am lost, and need help :)

Thanks in advance,

Maxime

MacBook Pro 13″, macOS 12.6

The below link from Apple on Erasing and External Drive

The trick is in Disk Utilities >> View >> View all Devices

Then choose the Upper Most Manufacture's Name of this drive

Erase and reformat a storage device in Disk Utility on Mac - Apple Support (CA)

Well I did that some many times :(

Every single time I performed these actions, it failed.

And again I can read all the disks I tested on my old Mac but also on my Windows machine.

There is something on the computer itself that causes this issue.

I tried in recovery mode >> fail

I tried with FileVault off >> fail

I am now thinking about reseting my Mac to factory settings but guess what, I need to backup my data and I can't :D...

I can only suggest to try again as per the Very Specific Instructions given

I just now, used the very same instructions on 1 USB PenDrive, USB SSD drive and a Rotational USB Drive and it does work here on an Apple Silicon Computer running Ventura 13.5.2

Thanks

Not really sure what “ Did it also . . . “ means ?

If you mean taking the drive to the Other Apple computer and Reformatting does not work. Then there is possibly an issue with the Drive itself ?

File a Bug Report to Apple here Feedback - MacBook Pro - Apple

Hi,

Well... I bought a new SanDisk SSD drive and this is the same...

I definitely don't get it.
