[Bug-ddrescue] Bad sectors initially marked as non-trimmed

[Scott Dwyer]

I have a drive that has many single sector errors (think the head flew 
across during a write). So after figuring that out, I used the -d -c1 
options in ddrescue to read sector by sector so as not to have to come 
back again. But to my surprise, the rescue log is showing 512 byte 
blocks as non-trimmed. How can that be? That is the default sector size, 
so it cannot be trimmed. Please explain this action by ddrescue.

I am using ddrescue 1.16 x64 on this, and the recovery is about 15% done 
after 3 days, so it will take about 20 days to finish. But I am worried 
that ddrescue will try to read all those "non-trimmed" areas again, and 
add a bunch more time.
