Here is what I did.
First check the share file system for error.
Login with SSH, get into superuser with su.
Unmount the share partition: umount /dev/md4
Run disc check: fsck.ext3 /dev/md4
It took a long time. Probably faster to delete the partition and reload it.
I had lots of errors. I ended up deleting all files after error check cleaned up the driver.
I then reboot Mybook, too lazy to find out how to properly mounting the partition again.
I add the following line to: /var/oxsemi/smb.conf
under [global] section:
oplocks = no
case sensitive = True
read size = 16384
read raw = no
write raw = no
load printers = no
I believe oplocks = no is what make the different.
read raw and write raw is for performance
Feel free to try and correct me if I'm wrong.
I'm still copying 68G of movies now. About 2hrs for 30G.
I don't care about speed now, I just want it to work.
Note: DO NOT use alt-web interface to edit the file. You WILL brick Mybook. Login with SSH and use vi or nano.
