I'm not 100% sure, but I think I've seen SD click the "cancel" button for me -- e.g. the dialog goes away by itself, just like it does when it auto-mounts a DMG.

I have found what I think is a repeatable bug.

1. Connect an external drive that contains a DMG that you wish to backup to.
2. Launch SuperDuper 2.6.1
3. SD comes up with the "Can't find...

I found out recently that Apple's Migration Assistant does a wonderful job at skipping files on a failing disk -- I/O errors that stopped other backup programs did not affect it.

So, if you...

I guess this answers the question "why is it better to have fewer large files (like OS 9 used to do) instead of a larger number of small files (like Unix does)?"

If the bottleneck is in writing tons of small files and the problem is really due to drive head seek speed, is there any way to speed it up? Can you do the copies using a mode that says "it's ok to...

SD Appears to freeze on large file copies

SD appears to freeze when copying very large files (e.g. my 14 gig Parallels drive image). I finally figured out it was not in fact frozen by using the 'sudo lsof | grep SDCopy' terminal trick.

Reminder or auto-dismount DMGs?

As I understand it, copying a DMG file that is mounted (and writeable) is a bad idea, as you can get a corrupted filesystem for that dmg.

Would it be possible for SD to figure out if a mounted...

Repeating my tests on a drive with more free space seems to relieve the problem. So maybe fragmentation was to blame? See http://www.shirt-pocket.com/forums/showthread.php?p=4667#post4667
