	Done last week on both disks. No smart error was reported.

	I have forgotten. /var/squid/cache was recreated with following command :

legendre# newfs -O2 -o time dk5
/dev/rdk5: 102400.0MB (209715200 sectors) block size 16384, fragment
size 2048
        using 554 cylinder groups of 184.84MB, 11830 blks, 22976 inodes.
super-block backups (for fsck_ffs -b #) at:
