Newbie: slow coping between from NTFS volume to EXT2

Hello guys,

First of all thanks everybody for your precious forum and wiki...
It helped me truly a lot.

I'm having this problem copying from a NTFS filesystem on an internal mounted 750GB HD to the other EXT2 750GB HD.

I'm currently using:

DNS 323 firmware 1.04 (not beta)
fun_plug 0.5 experimental
ntfs.ko from modules_v1.03

I installed the two HD into the DNS and formatted the first using the web interface (I had the 94% formatting issue as well and I fsck the file system after installed fun_plug)
then issued the following commands from the CLI

insmod /mnt/HD_a2/lnx_bin/ntfs.ko
mount -t ntfs -o umask=0222 /dev/sdb1 /mnt/HD_a2/NTFS_drive
mkdir /mnt/HD_a2/Storage
rsync -avzP  /mnt/HD_a2/NTFS_drive/ /mnt/HD_a2/Storage/

Now I'm not expecting to have a light speed file transfer, but rsync reported an average speed of only "600Kbytes per second" (4Mbit/s!!!).
My only guess is the ntfs.ko module is made for firmware 1.03 and not 1.04, am I right?

At the moment I solved coping the files throught the GB network connection using a laptop and having the NTFS drive conneted via USB... now I'm having an average of 16Mbytes/s.
But would be nice to find the reason and possibly the solution to this.
Any idea?

Then I'm wondering if we can format the main drive using fun_plug to avoid the 94% problem.
I guess is possible using "fsck reload" image, but when I tryed it was missing of some modules and it didn't let me do it.

I also noticed that the main disk some time is not cleanly dismounted. I guess it was because I tried the "thouch /tmp/shutdown" command, but I'm not sure.
Do you know were I can look to find any clue?
Doesn't the DNS check the filesystem if it is found not unmounted properly?


Plenty of questions for a newbie, isn't it? big_smile

Thank you,

GB

Take out the 'z' in your rsync command line.  z makes rsync use compression, which slows things down on the DNS-323, since the processor isn't beefy and neither is RAM.
