Boot from the CD-ROM
Install de Mini-root
run fsck on the boot disk
run de format utility
re-label de disk
mount the disk
By the way, I checked the disk on a Sparc 5 with Solaris 2.5.1, wich seems
to
handle this type of problems in a better way.
I'm not shure what caused the problem but it disapeared when I formated
the drive.
Thanks to all who reponded.
