Maybe you forgot to set corect current directory? 2 - error file not found.
Indeed, I did. I forgot to include the folder "ISO". I can't believe I've made such a basic mistake.
The new command being:
CDArchive.exe --mode=ext --extrdiscmode=dvd --extrdrive=F --extrsectdir="I:\CDArchive\ISO\SH5" --extrstart=461733 --extrend=493055 --extrrefcue="I:\CDArchive\ISO\SH5\SH5.cue"
However, this did not work, and I still get the same error.
I'd also select different directory for extracted sectors...
Is enough to extract them in a different folder outside of "I:\CDArchive" within the I:\ partition or it would be better to have them extracted in a different partition or hard disk?
Edit: Tried three options ["I:\ISO\SH5\SH5.cue", "M:\ISO\SH5\SH5.cue" (different partition, same disk), "J:\ISO\SH5\SH5.cue" (different partition and disk)], neither worked out.
