I am using DW 2.0 to rebuild the directory on a hard disk.

I successfully rebuilt the directory once (this took a long time to do), but
when DW asked to back up the data it had found, I realized that I didn't have
enough auxiliary disk space to do this, so I quit DW.

After acquiring another disk for backup, I ran DW again. This time DW
reported this error just minutes after starting on the target (corrupted)

"Disk Warrior has encountered an unexpected error (3001,1)." The manual
doesn't say what this error is.

I hadn't turned on the target drive between successive attempts to rebuild
its directory.

Any ideas:
1. what this error means
2. why I could successfully reconstruct the directory only the first time?
