Re: pdc metadata not detected on one older drive

  Hi Heinz,
I used dd looked at what was in the last 2048 sectors of my fujitsu drive and determined that the promise metadata was on a new offset 1775 sectors from the end of the disk.  I edited pdc.h to include the new offset and recompiled and now it works.  Smiles!
