Re: [Bug-ddrescue] Need help - ddrescue very slow - avg 27kb/s

Hi Ridz.

What do you mean by "I've formatted it to type 83".

Did you just change the partition type or did you actually format the filesystem?  I ask because writing a large file to an NTFS filesystem can get progressively slower.  If you just changed the partition type, that will have no effect on the filesystem at all.

In another terminal, type
mount

and post the output.  That will show what devices are moutned and what filesystem is in use.

Hi,

Need help. I've ran ddrescue for a few days and it only rescued 10G out of
500GB. I've tried various command of ddresue but I find the average rate
to be very slow as compared to other examples that I've read in the
archives. I've installed ddrescue 1.8 and 1.13. I'm new to Linux and I'm
not sure which version I'm using now. I've also formated my recovery
harddisk to ext3 in hope that the speed would increase. But unfortunately
it didn't.

My hard disks configs are as follows:

Problem drive : /dev/sdc  500GB NTFS - Windows detected it as unallocated
Recovery drive: /media/sde1  1TB ext3 - I've formatted it to type 83

Command:

./ddrescue --no-split --cluster-size=1024 /dev/sdc /media/sde1/rescue.img
/media/sde1/rescue.log

Current status:
rescued:   226559 kB,  errsize:       0 B,  current rate:    27594 B/s
ipos:   226559 kB,   errors:       0,    average rate:    27431 B/s
opos:   226559 kB,     time from last successful read:       0 s

Is there anyway for me to speed up the process.
Please help. Thanks.

regards,
Ridz
