General discussion • Cloned sdcard to SSD - doesn't work

Hi,

New to the forums.
Bought PI model 4 recently.
Spent fair amount of time (days) setting up the OS and everything, but it was set up on sd-card.

I now have external USB SSD that I'd like to use instead.

However, when I clone my sdcard to SSD (tried with both Macrium Reflect and Rescuezilla), it won't boot from SSD.

Now, I know there's stuff that needs to be tweaked first to get it to work.

I did everything that I can think of, but it still won't boot from USB SSD.

What I did:

1. Set USB as priority in bootloader
2. Enabled quirks in cmdline.txt according to this guide
3. Extracted its PARTUUID via "sudo blkid" command, mounted the SSD in my other Debian machine and manually changed it in /boot/cmdline.txt file

So, now my RPI is set up to boot from USB, quirks have been enabled and PARTUUID was set to match that of USB SSD's.
I plug it into USB 3.0 port, nothing.
Tried USB 2.0 port, nothing.

Tried the same on my other RPI, nothing.

Tried reinstalling fresh RPI OS onto that SSD, plugged it into USB 2.0 port and it works.

So:
1. SSD is not faulty
2. USB ports on RPI are also not faulty because I've booted USB3.0 devices on them before (just not this one, which is the only one cloned. Others were fresh installs)
3. Bootloader and cmdline.txt are not the problem, they were properly prepared

Still, it won't boot, unless it's a fresh install. What am I missing and doing wrong here?

Thanks
