Impossible de monter une partition

Bonjour j'ai un problème sur une partition et je ne sais pas comment la remonter voici le message :

/dev/md/rdsk/d1: BAD SUPER BLOCK: MAGIC NUMBER WRONG
/dev/md/rdsk/d1: USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
/dev/md/rdsk/d1: eg. fsck [-F ufs] -o b=# [special ...]
/dev/md/rdsk/d1: where # is the alternate super block. SEE fsck_ufs(1M).

/dev/md/rdsk/d1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
/dev/md/rdsk/d2: is clean.
/dev/md/rdsk/d3: is clean.
/dev/rdsk/c1t0d0s3: is clean.
/dev/rdsk/c1t0d0s5: is clean.
/dev/rdsk/c1t0d0s7: is clean.
/dev/rdsk/c1t0d0s6: is clean.

THE FOLLOWING FILE SYSTEM(S) HAD AN UNEXPECTED INCONSISTENCY: /dev/md/rdsk/d1 (/
cdrdata)

WARNING - Unable to repair one or more filesystems.
Run fsck manually (fsck filesystem...).
Exit the shell when done to continue the boot process.


Type control-d to proceed with normal startup,
(or give root password for system maintenance): resuming mountall
mount: /dev/md/dsk/d1 is not this fstype.

quelle est la solution ? Merci cordialement
