Can anyone explain to me what this issue solves? It sounds like some issue i have. I have found that some AVI files on my MyBook cause the network connection to drop. But these avi's can be as 'small' as 175mb. Is this the same problem?

Hi there, not sure if I have the same problem, but I got the WD My Book World 500GB for 2 days now and I have problems writing files to it.
After a few minutes it goes in error and after that I can't write files in the directory anymore. Anyone knows what that is?

Everything looks good. Double check oplock is off in mybook and Windows PC.
I'll take a look at my smb.conf and see what I'm using now.

I removed dev/md4 completly from /etc/fstab, rebooted the NAS, and then I run fsck.ext3 /dev/md4

fsck.ext3 /dev/md4
e2fsck 1.38 (30-Jun-2005)
/dev/md4: clean, 94/60555264 files, 16251787/121081888 blocks (check after next mount)

so I guess thats a good thing?

too bad I still cant transfer any large files without that "nice" I/O error

Re: Large file copy problem solved?

Mon, 18 Aug 2008 09:13:37 +0000

hi Pineapple sorry for the late reply. I can't run fsck hell i cant do anything anymore. for some odd reason I can't no matter what unmount my /dev/md4 volume, it's always the same thing:

sudo umount /dev/md4
umount: Couldn't umount /shares/internal: Device or resource busy

I've tried killing my NFSD completly, removing /etc/exports completly etc etc… booting into kernel - user mode only …still it complains the unit is busy..

Heh…. any ideas friend?

Thanks

Your drive is probably corrupted. Delete all the files in the share and:
Login with SSH, get into superuser with su.
Unmount the share partition: umount /dev/md4
Run disc check: fsck.ext3 /dev/md4

Re: Large file copy problem solved?

STILL having issues.. for crying out loud. :(

I just transfered 2GB = input/output error, give me a break.. i mean seriusly wtf

sorry for language guys but this is getting to my head

Not everyone has this problem so your experience is unlikely to indicate a solution but rather the plain fact that you have not been affected. Both the PUBLIC folder and your new BACKUP folder reside on the same partition and in addition this problem is not restricted to /dev/sda4 anyway.

I think it is quite clear that some drives are shipping/or develop over time corruption making it necessary to reformat the drive. Has anyone just tried asking for a replacement drive from WD?

Re: Large file copy problem solved?

Sun, 03 Aug 2008 05:36:20 +0000

This is maybe totally dumb idea, but so far I have 8 DVDs on it (=cca 30GB) without any crash or problem.
But - reading few previous posts about PUBLIC partition - that was the one pre-created on the drive. Well, I did not like the name, so I ignored it and created "new shared folder" (named BACKUP) and it is in the list of folders side by side with PUBLIC. I never used that public one and I'm copying and copying all my data into that backup folder.

Apart from creating that one shared folder, the unit is straight out of the box standing here in front of me. No other hacking, setting, formating or anything else.

Anyone thinks, that simply creating a new, (untouched by bad WD guys) might have solved the problem in my case? Could someone WITH the problem of copying try it as a test and post the result? Or they really fixed it in WD, since I have it only since yesterday (have no clue, how long that lied at the seller's shelf, I bought it of eBay)

Re: Large file copy problem solved?

Sun, 03 Aug 2008 05:24:46 +0000

Well, I've got my drive yesterday. Reading a bits and pieces before, I never tried the stupid WD anywhere, just set static IP in my router (not even inside the My Book), typed that IP in my browser, set "backup" shared folder in that My book admin program. Then opened that folder in windows explorer and moved home made 5 DVDs into it in the row without hiccup. (regular VOB size of 1GB). I turn it off then (was too late), turned it back on today and moved 3 DVDs (actually the 3rd is copying as I write this), no problem again.

So - do you think WD actually fixed some of the bugs? Or where "should" be problem of copying large files? Is it only when using the WD anywhere? (but if I understand correctly, people here are not using it anyway..?)

Since I'm writing, can I have question which belong in some other post I guess? I have totally ZERO knowledge of linux apart from knowing it exists somewhere in the universe. How much knowledge do I have to get before I should try to hack WD and install FTP? (I'd love to share and access my own video/audio over the Internet and that is not possible using the stupid WD anywhere.)

i've tried all of the solutions mentioned in here, and im still getting I/O errors moving my 9GB files.

Seriously im begining to regret I bought this piece of junk in the first place

Re: Large file copy problem solved?

StreetUrchin you are 100% on the spot. I formatted the partition and am up to about 100G so far…No issues.
I will submitt an edit to this post in day or two with step by step. (the step by step is a copy from another post but I am not sure where)

Thanks to all for he help!!!!!!!!!!!

Re: Large file copy problem FINALLY solved?

Sat, 19 Jul 2008 17:19:28 +0000

I finally gave in and reformatted the partition containing "PUBLIC". So far this seems to have solved the problem. Over 50GB copied [with a few files that are over 5 GB each] with no problems.

As soon as sure - will post step-by-step.

Thanx for the GREAT help…LW5

Re: Large file copy problem NOT-solved (yet)?

Sat, 19 Jul 2008 13:26:12 +0000

I did format as described in the 'troubleshooting' section of this site and everything seems to be fine now. Sorry, can't help you with the step-by-step guide you want, but a format is the way.

Re: Large file copy problem NOT-solved (yet)?

Fri, 18 Jul 2008 02:12:23 +0000

I have tried everything posted except formatting the partition
and I am concerned about trying this without being able to
back-up the entire drive first AND because I do not have any
other Linux machine up and running.

Anyone have a step-by-step on how to format ONLY the PUBLIC partition ? and
anyone know any way to do a binary backup using a windows platform ?

Thanx……LW5

Add this in your XP registry to turn off oplock in XP:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
"EnableOplocks"=dword:00000000

Re: Large file copy problem solved?

Thanks for updating LakeWater, gets me a stage further also - let me know how you get on.

Re: Large file copy problem solved?

Sun, 13 Jul 2008 22:19:39 +0000

I also have the same problem as StreetUrchin.

No /var/oxsemi/smb.conf file.

Anyone have a sample smb.conf file I can load ?

Thanks…..

UPDATE ……………………………..!!!!!!!!!!!!!!!!!!!!!!!

After additional research I found the missing smb.conf file referenced in a line of code within /etc/inetd.conf.

I have edited: /var/oxsemi/smb.conf to add (per Pineapple's recommendation):

oplocks = no
case sensitive = True
read size = 16384
read raw = no
write raw = no
load printers = no

So far GREAT. Have now tranferred 46 GIG with no problems!

A BIG thanks to Pineapple!

BAD NEWS !!!!

Unit is back to old tricks and is failing again…

Seems to be time related and not related to size or quantity of files transferred.

Back to drawing board………..

Hi All

Thanks for the invaluable advice on here, much appreciated.

My problem is that my MyBook deosn't have the /var/oxsemi/smb.conf file?

Any advice or am i missing something?

Many thanks

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.

Re: Large file copy problem solved?

Mon, 23 Jun 2008 15:08:32 +0000

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?

Re: Large file copy problem solved?

Mon, 23 Jun 2008 05:38:54 +0000

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!

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.

Re: Large file copy problem solved?

Sun, 15 Jun 2008 15:12:00 +0000

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?

Re: Large file copy problem solved?

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.

Re: Large file copy problem solved?

Thu, 29 May 2008 07:42:12 +0000

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! :)

Re: Large file copy problem solved?

Mon, 12 May 2008 21:06:36 +0000

Looks like some of them come with bad partition?

Re: Large file copy problem solved?

Sun, 11 May 2008 12:49:23 +0000

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

Re: Large file copy problem solved?

Fri, 02 May 2008 10:53:41 +0000

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

Re: Large file copy problem solved?

Thu, 01 May 2008 21:35:26 +0000

yep copied well over 90GB now not a hint of a glitch…………. you are now considered as a god in my house pineapple. top marks!
if it was'nt for you the kids would be playing football in the street with the drive right now.
cheers

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.

Re: Large file copy problem solved?

Tue, 29 Apr 2008 18:40:16 +0000

Ive been reading up on optlocks for about an hour now, I was thinking I had to disable it in Vista.. but I just done your steps above and so far I have copied 3GB and still going.. I have 32GB in-line 3 hours it says over a 54mb wireless connection…. ill tell you all about it later

Large file copy problem solved?

Fri, 25 Apr 2008 07:25:11 +0000

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
