ls reports input/output error - strange file

[Mertens, Bram]

Hi,

A colleague of mine tried to ungzip a file but encountered an error
becuase there wasn't enough disk space available.

A directory listing now reports:
$ ll |grep 11.18-09-2007

mappsacc.mle.mazdaeur.com-access_log.11.18-09-2007.tar.gz

When running ls on the "unzipped" file I get:
$ ll mappsacc.mle.mazdaeur.com-access_log.11.18-09-2007.tar
ls: mappsacc.mle.mazdaeur.com-access_log.11.18-09-2007.tar: Input/output
error

Any idea what happened here?  And how to remove this strange file?

Kind regards

Bram
