SSD installation on Raspberry Pi 4 failing

The guide is about SSD, not HDD. Don’t know, if this makes any difference. Also on the guide:

Boot meditation?

When you are waiting for the initial login screen you may experience extremely long boot times (>30 min).
If this happens to you you have multiple options:

1. Check the section “Use the right SATA to USB3 adaptor” above. Chances are that you are using a non-compatible SATA to USB3 adaptor or casing. Try the ELUTENG that I recommended above.
2. Try to connect your SSD through a USB 2 port (black) instead of a USB 3.0 port (blue). I know it sounds strange, but please really do! If this works for you, it may be your best option. Although USB 2 is much slower than USB 3.0 you will get a very fast system. But if option 2. works for you you should also reconsider option 1. It is very likely that your adaptor or casing is the culprit.
3. Check if your SSD casing or your SATA to USB adapter is based on a JMicron JMS583 bridge chip. There is a firmware update for this chip that solves the problem. For Sabrent devices the update for all affected devices can be found here . But I also remind you that my own Sabrent adaptor never really worked for me. Read 1. again!

The good news after that final trouble is:
You are done! Enjoy your new HA installation.

Did you check all of this?
