Det ser ud til at det gik godt. Output fra de 2 kørsler af ddrescue og den
efterfølgende kørsel af e2fsck er indsat nederst i denne mail.

Mit næste spørgsmål er nu: Er der en automatiseret måde at checke
resultatet på? Hvor gerne jeg end ville, så har jeg nemlig hverken tid
eller overskud til at gennemgå 361 GB data i hånden, for at finde fejl.
