Thank you for a wonderful tool.

You are welcome. :-)

I noticed I can't write a logfile to_/dev/hdb2/logfile_, but I CAN write to_/MEDIA/hdb2/logfile_ (Yes, DUH, I know, but)

I have added the following to the manual (as always, suggestions are welcome):

  'INFILE' and 'OUTFILE' may be files, devices or partitions.
  'LOGFILE' is a regular file and must be placed in an existing
  directory. If 'LOGFILE' does not exist, ddrescue will create it.

Also, do any of the drives need to be mounted?

Reading the manual one may notice that drives are rescued unmounted, but I have made it more explicit:

  Never try to rescue a r/w mounted partition. The resulting copy may
  be useless. It is best that the device or partition to be rescued is
  not mounted at all, not even read-only.

Does mounting matter when usingdirect disc access?

Mounting matters because other processes accesing the filesystem could interfere with ddrescue. Mounting read-only should not cause serious problems with or without direct disc access.

"So simple, so very simple, that only a child can do it." (New Math, Tom Lehrer)

I do not advise to let a child play with ddrescue. ;-)
