I read few in the net about the ahci-driver of the A20-Board. I have a Cubietruck and I want to use a hdd with more than 2TB. Is it - theoretical or in principal possible? My HDD is found but only 2TB of it.

It is possible. At least for banana pi M1 (A20) it can handle a 3TB hdd with no issues.

Just remember that you have to change your disk partition table to GPT instead of standard MBR because the latter is limited to 2.2 gb.

This is regarding SATA connection, if you use some kind of usb-to-sata adaptor, check that it is able to handle >2.2 TB

You should put "formatting 3tb drive linux" or similar to the Google. Not related to Cubietruck.

So I tried it and it works! Thanks !
