Gail,

I too have experienced this "lost VCR data" error.  Tech support has
explained to me that the lost VCR error is not critical because once ADSM
uses that tape volume, the VCR header gets overwritten and corrects the
problem.  Yes this problem causes ADSM to become very sluggish but not hang.
We installed new 3570 microcode that helped reduce the number of errors.  We
still occasionally see them.
