[Bug-ddrescue] Fwd: Error writing logfile - Invalid Argument

[John Parr]

Ok looks like more bad news for me unless someone can figure out how to
edit the log to get things going again.

Here's what happened:
I checked the console and saw device wasn't ready. I figured the log was
hosed but then I tried to unmount the drive and it wouldn't. I figured the
log was toast so it didn't matter. I checked the drive and the .DMG file
and log were now missing. I was using a new drive dock and thought maybe it
was problematic. So I forced it to unmount. I put the drive on another USB
dock that I have used many times before with success and the log and DMG
file were there! So I started it up again and it looked like it was going
to work but then it stopped and is just sitting there.

I have a hunch that it's because the log couldn't write and stopped. Is
there any way to edit the log to get it to pickup again or is my best
option to start over? The log doesn't really seem to contain much anyway.
It also appears to be missing the previous 7 hours plus of entries.

I am also wondering if there are any issues with version 1.19? Anyone have
any ideas?

Here's what's in the log:

I was seeing "Device not ready" for the disk I am writing my log and image
to.
Looks like TimeMachine fired off. I also disabled spotlight for the volume
I an writing to.

It does seem to have cleared but when I press "Enter" it doesn't start up
again. I did Q+Enter and then tried to startup again and got:


ddrescue: Write error: Invalid argument

mac:ddrescue-1.19 jn$ sudo ./ddrescue -v /dev/rdisk3s2
/Volumes/RecoveryDisk/MHD.dmg /Volumes/RecoveryDisk/MHD.log

Password:xxxxxxxxxxxx

ddrescue: error in logfile /Volumes/RecoveryDisk/MHD.log, line 0.

mac:ddrescue-1.19 jn$

Looks like my log is hosed.

The disk I am writing to is a 1 TB with plenty of space and it's showing up
fine.
