Here's your answer...

It never got any faster. Unfortunately, after getting back only 7GB of the 
500GB, the drive ultimately experienced internal, mechanical failure (i.e. very 
loud clicking). Repeated attempts to resume were futile because the system 
would not recognize the drive drive following the internal failure. And now the 
next stop is a pro data recovery service which will charge hundreds/thousands 
to get the data back.

I can't help but feel that this could have been prevented if there were some 
way to make ddrescue jump past large chunks of bad spots. I thought that was 
how ddrescue was supposed to work. Instead, I just experienced ddrescue bogging 
down at the first bad sector(s) it encountered. And there it remained until the 
drive gave up and died completely.

Really, what could I have done differently? Please educate me.

James

Subject: Re: [Bug-ddrescue] Slowness during recovery

Regarding the post from James W. Watts

I am curious to hear if it ever went any faster. 
I started today around 11:00 and at 2:00 I have a measly 32megs from a 500 gig 
260 used Western Digital piece o crap. 

I swapped it into a new shell and sit here on a macbook pro running ddrescue 
1.9 using this as my command
sudo ./ddrescue -B -n -v -r1 /dev/disk1 
/Volumes/LaCie/testtwo/savepleasetwo.dmg savepleasetwo.log
Log file
Initial status (read from logfile)
rescued:   25857 KiB,  errsize:       0 B,  errors:       0
Current status
rescued:   31170 KiB,  errsize:       0 B,  current rate:     2148 B/s
   ipos:   31170 KiB,   errors:       0,    average rate:     2607 B/s
   opos:   31170 KiB
Copying data...

With 0 errors what is up with it's current speed? Did I do something wrong? 
It's transferring the data to a Lacie Raid 1 terabyte drive as firewire from 
the WD hd via usb 2.0

Either way I am ultra happy to find a tool that seems to work compared to 
diskwarrior and the like


Hello all,


I kicked off a recovery this morning of a 200GB IDE hard drive. I issued the 

following command:



sudo ddrescue -v -n /dev/sdb /media/wd500gb/blc.img /media/wd500gb/blc.log



As you can see below, it is going very slowly. After running all day, it has 

recovered less than 2GB from the drive. Please tell me what I am doing wrong. I 

have started and stopped ddrescue several times and rebooted, unplugged/plugged 

the drives several times, too. But it continues to be slow.


I keep waiting for ddrescue to just leapfrog past the bad area(s) it is 

obviously stuck in, but it just keeps slogging away. How can I make it go 

faster?


At this rate it would take months for the drive to finish recovery.


Thank you,


James
