Raspberry Pi OS • Re: Trixie does not see/mount USB-SD card adapter

Used the RPI imager to clone the OS to the SSD. Shutdown.

How? Imager doesn't support direct clonig of an SD card.

Thank you for pointing out my error in documentation. Fixed in post #1 (used SD Card Copier)

Same HARDWARE. Running Bookworm, it sees/mounts the device. Running Trixie, it does not see the device.

There was a change with Trixie so that ext4 partitions no longer get mounted automatically in the Desktop.

As stated, I used Rpi imager on Windows to place Trixie on the SD card. I am pretty sure Windows can make, let alone rear/write an ext4 partition.

Stated now. It wasn't stated when I quoted your post.

I'm guessing that you meant "can't" not "can". Imager doesn't create the partitions it just does a block level copy of the contents of the OS image (which includes partition information) to the target drive than writes customisation data to the FAT32 boot partition.

At no point does Windows have to deal with ext4.
