Mount-Probleme zweite Platte (4.11 -> 6.1) : incorrect super block

Hallo,

habe einen zweite Platte in meinen Server, der z.Zt. unter 4.11 laeuft,
gehaengt und darauf 6.1 installiert. Versuche nun von 4.11 aus auf
diese Platte zuzugreifen, um waehrend des laufenden Betriebs die neue
Konfiguration anzupassen und Daten rueberzukopieren.

Leider klappt das mounten der Partitionen nicht:

# mount /dev/ad1s1a /mnt/ad1s1a
mount: /dev/ad1s1a on /mnt/ad1s1a: incorrect super block

Beim Booten werden beide Platten erkannt:

ad0: 76319MB <WDC WD800BB-00DKA0> [155061/16/63] at ata0-master UDMA33
ad1: 78167MB <Maxtor 6Y080P0> [158816/16/63] at ata0-slave UDMA33

Was koennte die Ursache sein und wie koennte man das Problem beheben?

Danke,
Manfred

P.S.: Hier die Ausgaben von fdisk und disklabel fuer die beiden
Platten. ad0 ist die mit 4.11 und ad1 die unter 6.1 installierte Platte:
