Large file copy problem solved?

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.

Update: 18-June-2008
Trying to copy 400GB from MyBook to another computer. the PC keep shutting down on its own. Add the following registry key if you have same problem:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
"EnableOplocks"=dword:00000000

Good to know it helps.
Oplocks works only when both side have it enabled. So as long the the one in MyBook is disabled, its good.

I wasn't aware there was a problem? Been backing up my 250GB hard disk with no problems? :)

The "straight out of the box" version didn't work. after+1gb my my book world edition 500gb freezes.
I really needed to format the /dev/md4 partition. and now it works really well!
I'm uploading now with a speed of 4 mb/s +8gb

Looks like some of them come with bad partition?

If anyone gets error message after trying to fsck:

Error allocating icount link information: Memory allocation failed

Here is solution: make 1gb empty file, mount it as swap, then run fsck.

Hi - first time on here and complete newbie on WDWE- I have the II 1TB.

I bought it last wk and formatted it RAID 1 as soon as I got home. Got 2 computers to see the drive (one XP, one Vista) even though I have to reset the router every time before I turn on the drive (haven't looked at fixing the ip yet). So far so good…

Now I have the same problem of the drive dropping off network disrupting large files transfers and reconnects by itself. To copy my 80GB of photos little bit at a time would take me all week - I'd rather buy a new drive which works straight away. TBH, I have no clue what you write above as I've never used linux nor all that computer literate.

Contacted support and they suggest updating firmware - but I believe I already have the latest. I've tried to search around before wasting people's time on forums but can't really find much help. Is there anywhere helps me solves the problem in laymen's terms?

I thought this product was aimed at consumers who can plug it in and follow included instructions - now I'm finding that the product is very poor in this regard - should I just give up and use it as a bookend? (I'm in Thailand and bought it at a computer fair so no return policy). It still frustrates me so much that such a big company with so much resource still make really shoddy, relatively simple products.

Thanks!

Hello!!

This also fixed my issue: When I was writing many files, it said the disk was write protected and I wasn't able to write anymore unless I rebooted the disk.

You're great!!! Thanks a lot!!!!!!

/edit: ooooooops problem continues… I'll continue looking for a solution :(

/edit II: trying after reformating, it now seems to work! :)

Hi,

ok, this will sound lame but would you be so kind and write down how you reformated? I'm asking because I'm hoping that you'll reply in the way which will let keep my things on a hdd. I have half of my 1TB MyBook full and no other place where to move everything. Is there any way?

Don't reformat if you want to keep all the files.
Run the disk check to see if any files are corrupted. If they're corrupted, you can use them anyway.

Hi,

I've tried to run fsck.ext3 but when the disk check gets to the phase4 it says that there is incorrect size of: "i_node… is 938423948732 and should be 0". Than it asks if I want to fix it and if I say yes the fsck immediatelly quits without fixing my hdd :( Any ideas?

You got corrupted files. You'll need to delete the corrupted one to get it going again. Move as many as you can out of the drive. You can run fsck.ext3 with option to answer yes to all question. I gave up on mine and just deleted everything.
