If you've already checked your cables
and ran fsck and got lots of errors,
then YES I agree. You probably should
replace the disk.
Sorry.

dcheck(8) System Manager's Manual dcheck(8)
NAME
dcheck - Checks directory consistency
SYNOPSIS
/usr/sbin/dcheck [-i inumbers] [filesystem]
OPTIONS
The -i option is specified with a list of inumbers. If a specified inumber is found in a directory, the dcheck command displays the inum-
ber, the inumber of the directory, and the name of the entry.
DESCRIPTION
The fsck command supersedes the dcheck command for normal consistency checking.
The dcheck command reads the directories in a file system and compares the link-count in each inode with the number of directory entries by
which it is referenced. If a file system is not specified, a set of default file systems is checked.
To get optimum performance, specify the raw version of the special file because the ilist is read in large chunks.
RESTRICTIONS
Because the dcheck command uses two passes to check directories, it may produce erroneous diagnostics if active file systems are checked.
ERRORS
If a file is found and the link-count and the number of directory entries do not agree, dcheck reports relevant information. Allocated
files that have 0 link-count and no entries are also listed. A potentially dangerous situation occurs if there are more entries than links.
If entries are removed and the link-count drops to zero (0), the remaining entries point to nothing should be removed. If there are more
links than entries or if there is an allocated file with neither links nor entries, some disk space may be lost.
