Hi Pauli,

Welcome to the forum.

The drive is replaceable, though it would typicaly be done by Meridian or a dealer.

Yes, a WiFi router is required (and internet access whilst ripping).

Backup is done to a 3rd party drive, using the supplied Meridian ControlPC/ControlMAC software and is fine to use.

Trust this helps.

Regards,
Carl
