Error copying large files from USB HDD to MyCloud

I am trying to copy a some large files (several GB) from a USB HDD to mycloud drive using the WD My cloud software as described in this post:http://community.wd.com/t5/WD-My-Cloud/Transferring-Large-Amounts-of-Data-to-the-My-Cloud-and-a-Coupl-e/td-p/620219but the copy grinds for some time and then fails. Is there a limit on the file size or amout of data that can be copied in one operation. I am using latest software and firmware. Windows 8.1 if that is relevant. Thanks in advance.

No, I'm using copy and paste within WD My Cloud for desktop app to avoid having to pull the files across the network. Source USB HDD is 2TB WD Elements and I am using the original USB 3 cable supplied with it connected direct into MyCloud device. I have also checked the USB disk with chkdsk while plugged into Windows. The files seem to copy if I do it over the network, but its very slow.Ah that was one small detail left out of your initial post that changes things. It is generally NOT recommended to connect a USB drive directly to the My Cloud if copying a large amount of files (or files in excess of 30 or more GB's). Slow transfer speed over the USB port on the back of the WD My Cloud units are a known issue. Search this site and you'll find lots of threads on it. The previous posts indicate better ways to copy the data from a external USB drive to the WD My Cloud.

Can anyone share fix or determine methodology to fix?

Hi Joe,
Was the error gone when you turned off the Bitlocker from this drive?

Error code 8084 when copying large files from VNX servers

Hi,
We are experiencing problems when attempting to copy large files from our central VNX servers (EMC) using the connection format of smb://<host>/. With Mavericks this will be SMB2, presumably. Anything over a few MB in size fails with the error:
The operation can’t be completed because an unexpected error occurred (error code -8084)
Looking in the Console logs we see the following:
kernel[0]: smb2_smb_read_write_fill: len got reduced, must be running low on credits
If we attempt this on OS X Mountain Lion or below we have no problems.
If, with Mavericks, we connect using the format cifs://<host>/ then file transfers work.
Has anyone come across this before? Thinking I should also post a bug...
Cheers,

Keep losing connection to Time Capsule while copying large files from Vista

I keep getting "Error 0x80070079: The semaphore timeout period has expired" while trying to copy large (1GB+) files from my Windows Vista Business 64 bits laptop (this OS is running on a MacBook Pro using BootCamp) wirelessly connected to a Time Capsule. The wireless connection to the Time Capsule is interrupted when this error occurs and then I can re-establish the connection. The problem seems to only occur when I copy large files or when I copy many files at once.

I believe that this problem is resolved as I describe here:

Copying hangs when copying large files from DVD

I'm having trouble copying large files (>2GB) from DVDs to my built-in hard drive. When I drag the file icon from the DVD window to the desktop, the progress bar pops up almost immediately, and says "0 KB of 2.3 GB copied" and "Estimated time left: 1 minute" -- and then it just sits there, doing nothing. In some cases, after five minutes or so of inactivity, the copy finally begins... but most of the time it never does. Force-Quit doesn't help; the only way out is to do an emergency restart and try again.
This problem began when I upgraded to Tiger, and several members of my office group have been experiencing the same problem on their own computers as well.
I've poked around the forum looking for answers but the only thing I could find that looked related was a conflict between iSight and some third-party external hard drives... but none of us have iSight, and none of us are using third-party external drives, so clearly that's not the issue we'rehaving.
Any help out there?
iBook G4 Mac OS X (10.4.6)

Michael, I occasionally notice anomolous behaviour when files get dragged between volumes. Mostly the copying window shows an accurate and immediate indication of what's going on, but other times it just looks like nothing's happening, the display never changes, yet, it is in fact copying the files over. Now, if you're copying 2gb files from DVD to HD, it's gonna take some time, more than 5 minutes, so I'm wondering how long you've left it before forcing it to quit?

Help copy large file from iPhone to PC

Hello Everybody.
I’m coding the Record application. However, I have problem with copying the file from iPhone device to the PC after recording. I used Attach File function on Email but it doesn’t allow with large size > 10MB file. I haven’t found any solution yet for this problem. iTune 9.0 has “Include Voice Memos” function, can i do the same with my application ? “Include My App” e.g.
Anybody knows other solution for this problem?
Thanks for read

You could check your approach against this article: http://support.apple.com/kb/HT4083. If you are still having trouble you could try an app that will send it wirelessly, such as PhotoSync.

OS X 10.4.7 server: Samba leaking ram when copying large files from windows

Hi.
I'm having problems with:
Copying files from windows clients to OS X Server 10.4.7 uses up the RAM needed for the files to be copied.
If I copy a 3GB file, it uses 3GB of RAM
If I copy a 5GB file, it uses its 4GB of RAM, plus VM.
If I copy 11GB of files (that is several little files, plus some big by dropping a folder to the share), it consumes all the RAM the machine has, and because of VM paging, whatever other clients are reading from the disk (XRaid) start to have hiccups.
The RAM of the machine NEVER gets flushed after the copying has finished. So Samba is unusable as it is. I have four Xserves with 4GB of RAM, with 4 XRaids connected each one to each Xserve with its Apple Fiber Channel card and cables.
I already did the ack=0 thing, got the size of inet.tcp.sendspace and rcvspace to 8388608 and the buffer to 16777216.
The transfers rates are up to 70MB/s with 2 channel 1gb trunking, and at very sustained rates..
We are using these to edit video content (DV 25) in Sony Vegas with 2 or 3 clients for each server.
Any suggestions?
Thanks very much.

Can't copy large files from DVD

Hi all,
I'm trying to copy a 4.3 GB .tar file from a DVD onto my harddrive, but it will only copy about 1 GB before I get the error
Cannot read: Input/output error
I can copy smaller files just fine from the same DVD and other DVDs, but nothing too large.
Does anyone have any suggestions?
Thank you.

Brasero checks immediately after the burn. I presume your DVD is a bit older than one day . If not, you just burnt yourself a coaster.
I know there are some Windows programs to check the integrity of an optical disc, but I don't remember their names (nor do I know something like that for Linux).
I would do a few copy trials, with dd. If you always see it break on the same size and you have plenty of space left, then I think there really is a problem with the data integrity on your DVD. I have done copies with dd from optical media before, and I think you can be pretty sure the data is corrupt if dd can't pull it off.

I cannot copy large files from my hard drive

My MacBook Pro 15 is on OS X 10.8.5 (12F37) and I reformatted my external hard drive to Mac OS Extended (Journaled) but cannot copy my virtual machine 53GB file from my hard drive to the external drive.

If it was a partition it would not be a VM file.
This is what you said:
if you are trying to copy a virtual windows machine
I see no mention of a Windows partition here.
As I said before you should test your suggestions to ensure that they are correct, and you should do that prior to suggesting them, and It would help if you understood the difference between a file and a partition.

Error message -36 when copying large files from Firewire drive

I have kept several large audio files as backup on an external LaCie Firewire drive. When trying to copying them back, almost all of them starts to copy, then stops and (after a minute or so) report error message -36.
I have run both Apple's Disktools and the latest Diskwarrior, but no errors are reported. I gues the audio files must have become corrupted... What do you suggest that I do? The contain valuable audio information that I really don't want to get lost.

Airport Network goes down when copying large files to USB network drive

My apologies if this has been covered before. This is my first post and I am new to the forums.
For several months my wife and I have been using the Airport Extreme 802.11n (Gigabit Ethernet). I use Windows and she uses Leopard. We recently purchased a Western Digital MFL Pro (500GB). If the external drive is connected directly to my PC via USB I can copy to it without any problem. If the external drive is connected to the Airport via USB then if you copy files (generally) over 2GB it takes the whole network down. At that point we have to unplug the Airport wait a few seconds and then plug it back in. It's frustrating because the drive works when connected directly, but not when it's connected to the Airport.
Also, I am hardwired to the Airport (Ethernet) so it is not a wifi issue. Our firmware version is 7.2.1 which is the latest, plus I also updated the software that runs under Windows (5.3.1).
Does anyone know what is happening here? Is this a known issue? Is there a work around or fix available?

I've also experienced this problem with my AEBS and an Iomega 500GB MiniMax drive. My Iomega Drive was formatted for HFS+ from the beginning and I've had no problems accessing it from both my Mac and my Windows PC.
I've been monitoring these groups for signs of a solution, I've talked to the geniuses at one of the Apple Stores near me and so far there's no sign of a resolution. I've sent in feedback to Apple but had no response to it so far (don't know if that's usual).
The only suggestion that has been put forward so far is to take my AEBS, Iomega Hard drive and laptop to an Apple Store and demonstrate the problems there in the hope that a solution can be reached.
I've since purchased a 500GB Time Capsule but haven't had a chance to do the same test on that yet, but as far as Time Machine backups go its worked flawlessly so far (touch wood).
Regards,
Jason

Unresponsive system when copying large files drive-to-drive (x86_64)

I'm running Arch x86_64 on a quad core Xeon processor/P35 motherboard w/ 4 gigs of RAM. I also have two SATAII, 7200 RPM HDDs. For the most part, Arch is a VERY responsive platform. I am noticing some really odd unresponsiveness that only happens when I copy large files from one hdd to another hdd.
Symptoms:
-Mouse cursor skips (doesn't move smoothly)
-Windows such as firefox or shell don't move smoothly across the screen if I move them
-Keyboard lag - as I type this post ) my fingers are going faster than the text is appearing
Once the copy is finished, everything is normal again. I swear I read someone else reporting this behavior, I just can't find it. Two questions:
1) Is normal for the x86_64 kernel?
2) If not, what can I tweak to remedy it?
EDIT: Ack! Found the post I remembered reading:

if the file is bigger than 4gig(uncompressed) then u need swap partition, as the first thing it does is copy the file to memory and if it overflows it is bad. then your server is 1/3 options, either server/middle/desktop. if it is server, it doesn't care what framerate u get on X. then there is the timer. I'm running mine at 300 but arch's default should be 1000. the higher it is the more it "checks" what needs to be done with files, events, etc. then there is the file system type and block size factor. if ur block size is really low like me(1024k) then ur hd has to write more times(on and off) just to write out the huge file. so for huge files, format with huge block size(4096k?) so that the hd does less work.

Can't copy large files to airport extreme USB drive.

Hi Everyone,
I'm positng because I'm unable to copy large files to an AirPort Disk using Moutain Lion. I have the following setup.
AirPort Extreme:
- Firmware version: 7.6.3
- Airport disks secured by password
External Drive:
- Seagate 3TB External Drive connected to Airport Extreme thru USB
- Mac OS Extended (Journaled) Formated
Computers:
- MacMini(Mid 2010) - MacBookPro 13" Retina
- Both have Mountain Lion with latest updates
Airport Utility:
- Version 6.2
I am using the drive for a backup of .mv4 files. Files up to 4g transfer just fine. Files over 4g will get all the way to the end and throw a -36 error. If I plug it into my mac the files copy just fine. I have googled the issue and get all of these fat32 and win7 issues. Not really relevant from what I can tell.
I have also connected other drives the the Airport formatted the same and get the same problem.

That's not entirely unusual as using that port on the AEBS for backup is an iffy business, especially if you are trying to use Time Machine which is completely unsupported by Apple.
There may well be something wrong with the file you are trying to transfer, hence, the -36 error. I have no solution for you. Generally, there is no suitable solution. If you get the error while trying to copy several files at once, then try doing one file at a time which sometimes works. Archiving may enable you to transfer the archive, but then dearchiving on the destination may not work.
You can check the filename length and look for illegal characters or just rename the file, if possible. And, don't overlook the possibility that the file itself is corrupted even if it does not appear to be so from outward appearances. Lastly or firstly, try transferring the file to the external drive hooked up directly to the computer instead of the AEBS.

Back up - large files - external USB drive - copy failure

Just the facts:
I cannot backup my Music folder to an external USB FAT32 drive. I have no large single files over the FAT32 limit of 4GB. The copy process stops at various amounts progess: 500MB to 6GB. My Music folder is ~16GB total in size. I recently did a clean install from Tiger. I had no issues moving my 14GB Music folder in Tiger to this same external drive.
1) Has anyone solved this?
2) Has anyone talked to Apple support in a store or over the phone on this?
3) Anyway to highlight a (likely) important issue with Leopard to the Apple folks?
There are numerous posts all dealing with moving/copying large files. Seems to be a common issue to Time Machine, iDisk, external drives, copying large folders to Desktop, and others.
Cheers,

PS New Mac user and really like it so far. I realize these are just Leopard "birth pains."

This is the Windows forum, not the Mac forum.
But it's the same. Simply drag the iTunes folder to the external drive.
Or use a backup prgroam such as SuperDuper!
You do have a bootable backup of your internal HD, correct?
