Asking the same question many times may get you a different answer but the
likelihood is that a different answer will be wrong. Many experts have
already answered your question and they all seem to agree. What you want to
do can't be done without losing data. It is most likely the drive is bad.
Your best option at this point is to backup what you can from the drive,
overwrite track 0 then try to repartition and format the drive. Do not trust
this drive with any data you don't mind losing.

One possible alternative is spinrite. It can be purchased here www.grc.com I
have never used so I don't know if it will do what you want. Make sure you
have the data on the drive backed up before using it.
