Hi John,

The use of ddrescue in Mac OS X is a bit different than other systems.

1. I haven't got the --sparse option to work properly in OS X. So i dont use it. Maybe others will say otherwise.

2. You should use /dev/rdisk0s6 this way you will be using the raw device. Much faster recovery.

3. You are already using a log file, this way you can stop ddrescue just by pressing ctrl-c and resume it by running the same command pointing to the same log file.

For normal rescues this should cover it. For unnormal cases you should play around with it.

Happy rescuing. :-)

Greetings friends,



I have run into a tricky recovery. I have never needed more than the following 
to recover most drives âEUR¦



"sudo ./ddrescue -v /dev/disk0s6 MyRecovery.dmg MyRecovery.log"



Things didn't look like they were rolling along so I went to check the manual 
for starting and stopping. I noted there was a --sparse option which I know Mac 
OS X would likely support but I am not sure how to implement it.



I am also not sure how to stop ddrescue then later resume. I think this would 
be handy to know.



Does anyone recall seeing any sites that have some good examples of usage as it 
applies to Mac OS X?



I originally started with tips from the Mac OS X Hints website so if there are 
other sites that anyone knows of I would appreciate being pointed in their 
direction. I know this isn't a bug but I don't know where else I can find the 
information.



Regards,

John
