 on mounted ext3 filesystem

 I have a similar problem... but not with ls.
 
 # md5 biglonguglyfilename.zip
 MD5 (biglonguglyfilename.zip) = 511fdc3352d9265ffac0d472de7bb994
 
 # md5 differentbiglonguglyfilename.zip
 md5: differentbiglonguglyfilename.zip: Input/output error
 
 These files can be read with no problem in Linux, whether I mount the
 system as ext3 or ext2.
 
 I did not create this file system; it was from a 3rd party.
