Hi
Andrew,
Thanks for replying. I was initially recovering to an NTFS filesystem. The
average rate never went higher than 27kb. I've read that writing a large
file to NTFS filesystem can get progressively slower. Therefore, I
formated my recovery harddisk to ext3. However, there was no improvement -
the average rate is still 27kb and the current rate never go beyond 30kb.
For the recovery harddisk, I had formatted it following the instructions
at
http://www.idevelopment.info/data/Unix/Linux/LINUX_PartitioningandFormattingSecondHardDrive_ext3.shtmlResult of mount of the recovery harddisk:
/dev/sde1 on /media/sde1 type ext3
(rw,nosuid,nodev,relatime,errors=continue,data="">
regards,
Ridz
