I also had a disk failure of my FreeBSD 1.1.5.1 drive somewhat recently.

I also see this.  At first I thought it was because I was trying to
restore a FreeBSD 1.1.5.1 dump tape under FreeBSD-current as of August,
but even after re-installing FreeBSD 1.1.5.1, the restore still fails
in this same manner.  So I've concluded that the tape itself was corrupt.
However, if you also see this same behavior, it may be a software
bug after all and my tape may still hold valid data.  Another data
point is that an old FreeBSD 1.1 dump tape restores fine under both
FreeBSD 1.1.5.1 and FreeBSD-current.

This fails for me.  I get a resync error message and the restore process
appears to hang w/ the tape drive light always on.
