CheckSum errors?

I get the following error with the latest nigthy build of
nutch:
 
WARN  fs.FileSystem - Moving bad file
/data/nutch/crawl/tmp/mapred/local/reduce_ur2fab/map_1.out
to
/data/bad_files/map_1.out.-1786551$
WARN  mapred.LocalJobRunner - job_ofp9by
java.lang.RuntimeException:
org.apache.hadoop.fs.ChecksumException:
Checksum error:
crawl/tmp/mapred/local/reduce_ur2fab/map_1.out at
33316864

Someone else said this is because of a bad harddisk? But I
can't do
fsck because my data is being stored on a cifs mount.
When I did a chkdsk on the drive partion on the remote
machine there
are no errors. Is this anything else that can cause this
error?
 

Usually this is due to bad memory, not harddisk.
