MacBook M2 External SSD Samsung T7

[Dak7385]

Hi

I am fairly new to Mac and would like to understand more about using my Samsung T7 with the M2.

I received my T7 and set it up with APFS. When I click on the T7 icon on my desktop, "get info", it does indeed show APFS and read and write. Image attached.

However, when I set up time machine time machine to use the T7 and click "get info", it shows APFS sensitive and is read only. Image attached.

I am very happy with the backup speeds on the T7, but would just like to understand why the system would change the T7 to APFS sensitive when adding it as time machine.

I noticed that when I added the T7 to time machine, the icon on my desktop changed from a yellow icon labelled T7 to an icon with the time machine showing.

I am hoping that this is quite normal and that someone will confirm this.

Thanking you in advance.

Regards

I noticed that the format for the drive changed to APFS case sensitive after you designated it as the Time Machine drive. From what I’ve read so far that seems to be the preferred format for Time Machine drives under Monterey. I’ll try to find a more definitive answer and post the link.

I am running Monterey on an M1 silicon mac and it shows exacly the same as you have found in relation to TM.
When set up It changed the format to Case Sensitive and also shows as Read Only in Get Info but, of course, TM can write to it.

I can't give you a link, but I can tell you that my two TM EHDs were automatically formatted to APFS (Case-sensitive) as were the two TM drives on my friend's Mac when he upgraded to Monterey.

@pineand @IWT . Thank you both for confirming my issue is quite normal. I was slightly confused as to read only, but yet was able to write to TM.

Many thanks.

It's read only to YOU, but read/write to TM. That's how it works now.
