You could use a more complex delimiter. Juding from your error message,
you are usingh DTS, which I don't know much about. In BCP, my
favourite for character-based export is
-c -t @!@ -r "\n<->\n"
which sets the field separator to @!@ and the record separator to
<-> alone on a line.

Here is a Perl script that you could use to track down problematic
lines in the file:
use strict;
my $no_of_fields = 5;
my $delim = qr/\|/;
my $lineno = 1;
my $file = 'E:\temp\slask.txt';
open(F, $file) or die "Cannot open '$file': $!\n";
my $line;
while (defined ($line = <F>)) {
my @fields = split($delim, $line);
if (scalar(@fields) != $no_of_fields) {
warn "Line: $lineno, no of fields: " . scalar(@fields) . "\n";
}
$lineno++;
}
close F;
To do it in T-SQL, you could import the file to a one-column per
table, with one line in the file per row. You could then find the
odd rows with:
SELECT * FROM tbl
WHERE len(data) - len(replace(data, '|', '') <> @no_of_fields
