[Bug-ddrescue] Disk size wrong?

[David Morrison]

Hello

I am trying to copy a 500GB disk from an iMac that was damaged by a 
lightning strike. I have it in a USB case connected to an iMac 
running OS X 10.6 (Snow Leopard). (It is my disk recovery machine 
which has all the tools set up and ready to go.) ddrescue is 1.23

It has been running for about 10 minutes, but the pct rescued is still zero.

Then I realised that non-tried is not MB but PB, presumably 
Petabytes, a very, very large number.

bash-3.2# time ddrescue -n /dev/rdisk3 ./Orr500GB.dmg Orr500GB.log
GNU ddrescue 1.23
Press Ctrl-C to interrupt
     ipos:   10100 MB, non-trimmed:        0 B,  current rate:  15138 kB/s
     opos:   10100 MB, non-scraped:        0 B,  average rate:  15563 kB/s
non-tried:    9223 PB,  bad-sector:        0 B,    error rate:       0 B/s
  rescued:   10100 MB,   bad areas:        0,        run time:     10m 49s
pct rescued:    0.00%, read errors:        0,  remaining time:         n/a
                              time since last successful read:          0s
Copying non-tried blocks... Pass 1 (forwards)

So it seems that somehow the disk is reporting itself as much larger 
than it really is. Presumably this means the controller is damaged?

I guess I can leave it going until it has reached at least 500GB in 
about 9 hours then stop it?

Or if it stops for some reason, I can add -s 520GB to the command 
line when I restart it.

Cheers

David
