Network Drive Losing Connection During Large File Transfer...

Hey, everyone.
Recently bought an Airport Extreme and LaCie USB HDD/Hub for my hybrid Windows/Mac home network. I formatted the drive with FAT32 as instructed, and hooked it up.
My first order of business was to back up all of my media on my Windows desktop machine, but it hasn't been working out so well. A short while after starting the 35+ gig transfer (a few minutes at most), I get an error message saying the the destination folder is no longer there. Sure enough, checking 'My Computer' shows that the drive is now a 'Disconnted Network Drive'.
Cycling power on everything and rebooting Windows restores the network drive, but the core problem remains.
Anyone else seen this and have any idea how to deal with it?
Thanks in advance for any help.

Hi,
I'm having the same problem. Here's the relevant parts of my setup:
Airport Extreme
HP printer and Western Digital "My Book" 500 G USB drive connected by 4/1 usb splitter
MacBookPro connected via Gigabit
Windows XP PC connected via Gigabit
My media I loaded on the usb drive by directly connecting the usb to my PC, I've also loaded other iTunes media to the usb drive from the mac book. If I point iTunes on the PC at the usb drive I can play the media just fine. When I try to copy large files (700 MB) from my PC to the usb drive (via the airport) I'm told the destination folder isn't there. I've also noticed the windows tooltips telling me that it lost the internet connection, and if I have the airport utility open on my mac it also looses the airport for a few seconds. I am able to copy small files (largest that's worked so far is 1.6 MB) the usb drive via the airport.

Network Drives Losing Connection from Server 2012 to Windows 7 64bit Machines

I have about 20 users at my facility and recently upgraded our server from one running server 2003 to one running server 2012. Since that occurred, I have had numerous issues that I did not encounter on the old server.
Lately, users have been losing connection to the shared network drives randomly and constantly. The drives will come back on-line on their own but it could be 2 minutes or 30 minutes before they do and when users are in the middle of working on a document
from the network, they are unable to save until the drive comes back. Manually disconnecting and re-mapping them works sometimes but then the problem will re-occur. I have tried re-doing the shares and security settings and run a couple of supposed hotfixes
on the client side and the server side to no avail.
Now our regional office is suggesting that I re-connect the old server and then rebuild the new one with server 2008 r2, something I would like to avoid if possible.
I feel like this is a simple setting that I am missing, no conditions have changed except for the new server.
The server is a Intel Xeon CPU E5-2609 2.40GHz with Server 2012 64 bit on it. All computers (except on on 32 bit) are running Windows 7 Enterprise edition 64 bit.
Please help.

I made this change to the registry on the server and am waiting to see if I have any more drops.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters
Value:
autodisconnect
Data
type : REG_DWORD
Value:
ffff (Hex)
There was a client side change suggested but I am missing that value for the client side change and others in the organization who don't have it are not experiencing this problem.

I have an iPod Touch but I currently don't have a PC. I found an app that would allow me to connect to my network drive and I was able to transfer music files to it. These files do not show under the Music app and I can't find any way to do it.

I need help from some Apple people. I have an iPod Touch and I wanted to load it up with some fresh music but I currently don't have a PC. I found an app that would allow me to connect to my 2TB network drive directly and I was able to transfer a bunch of music files to the iPod. Unfortunately, these new files do not show under the Music app and I can't seem to find any way to convince the iPod that they are music. I can play them through the file manager only. Android doesn't have this problem, any music I put on my phone is recognized as music and can be played through any of the music apps. Am I missing something or is Apple to inflexible to handle this?

You can't. The only way to get songs in the Music app is to sync from a computer or to download from iTunes.

Slow large file transfer speed with LaCie 1T firewire 800 drives

I am transferring two large files (201gb and 95gb) from one LaCie 1T firewire external drives to another one (using separate connections to a PCI Express firewire 800 card in my Quad G5. The transfer time is incredibly slow – over for hours for the 201gb file and over 2 hours for the 95gb file.
Does anyone have any ideas why this is so slow or what I might try to speed up the transfer rates?
Thank you.

External USB Hard Drive disconnects during large file transfers.

I have a Western Digital 2TB USB Hard Drive that Ive been using perfectly for a couple of years on my MacBook Pro. A couple of months ago I bought a 27inch iMac and started using it as my main computer. So I had that hard drive connected to my iMac.
I started to notice that during large transfers (be it many files or 1 big one), usually into the Gigs, I suddenly got a warning message saying that the Hard Drive was inappropriately disconnected. It doesnt appear in Disk Utility so I have to manually connect and disconnect the drive in order for it to show up again on the iMac. I tested it again on my MacBook and the same thing happened.
Another problem:
Sometimes it will dissappear from the iMac without a warning message, it just doesnt show up. (Usually after long periods of inactivity). I then have to manually disconnect and connect for it to show up.
So what do you think? Is my Hard Drive Dying?

I've been having similar problems with Lion on both external USB2 drive docks and more recently a Mediasonic 4 bay Firewire RAID drive. It was suggested that powersaving mode shut these down but changing that didn't completely solve the problem. I'm returning the Mediasonic for a replacement but suspect that it is something in the OS that is causing it.
If the replaced drive still causes the problem, I'll do a rebuilt of the system, eliminating apps that were migrated over, even though the system is only 5 months old. If anyone has solved similar issues, please let me know as well. Thanks.

IPad (3rd gen) losing wifi connection during large downloads

Hi,
I am having a problem with my iPad 3rd generation (wifi only, 64GB) running iOS 6.1.3.
When I download large files (e.g. via the iTunes app, the BBC iPlayer app, The Economist app), my iPad almost always loses wifi connection a minute or two into the download, and often stays disconnected until I go into Settings > Wifi and select my home network again. If I resume the download in relevant application, the same issue will typically recur within a minute or two.
I am not having any other problems with this iPad - general internet browsing / streaming of video has been fine. I originally thought the issue was only with the BBC iPlayer app, but sadly have found it to be more widespread.
I have tried to "forget this network", resetting network settings, restoring my entire iPad (twice), and resetting all settings - none of these have stopped the issue. Interestingly, during the first restore of the iPad I received ugly BIOS-esque messages relating to AppleBCMWLANCore, which disappeared after a hard reboot (power + home buttons together), and did not recur on the 2nd restore.
Anyone else experiencing something similar? Any suggestions to fix this?
Cheers,
James

Locate the iPad as close as possible to your router.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

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).

Jason

Java.io.IOException during large file processing on PI 7.1

Hello Colleagues,
for a large file scenario on our PI 7.1 System we have to verify with big file size we are able to process over PI.
During handing over the large file (200 MB XML) form the Adapter Frame Work (File Adapter) to the Integration Engine we receive following error:
Transmitting the message to endpoint http://<host>:<port>/sap/xi/engine?type=entry using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error transmitting the message over HTTP. Reason: java.io.IOException: Error writing to server.
The message processing stopped and message still lies at Adapter Frame Work. Large files up to 100 MB we are able to process successfully.
Please, could you tell me why this happened and how we are able to solve it?
Because there is not a java.outofmemory exception however a IO exception i think it could be an memory issue?!
Many thanks in advance!
Regards,
Jochen

Hi Jochen,
Indeed the error is IO Error and it is because the Adapter engine was not able to send the message to Integration server. But it happens due to memory/heap size issues.
Look at these thread, they are having the same problem. Please try the remedy measures suggested by them
Mail to Proxy scenario with attachment. AF channel error.
Error with huge file
problem with big file in file-to-proxy scenario
Is there any additional information in Adapter messaging tool.?

IdeaTab A2109A - large file transfer

Hello,
Trying to transfer a large file (4.5GB) to tablet IdeaTab A2109A connected to a laptop, this gets truncated to 1.2GB and transfer stops. Smaller files are copied fine, but seems that larger files have problem.
Tablet has no SD card attached, thus I'm transfering directly to its internal storage (11GB free space).
Android ver. 4.1.1/ kernel 3.1.10
Please share your ideas/experience/solution on transfering large files for IdeaTab A2109A.
Thanks!

I've never tried transferring a file that big, but I've found using adb push and pull to transfer faster than using MTP.

When my Bluetooth disconnects during a file transfer where is all the data? why do i have to start over?

while transfering a large video file from my phone to my imac i lost the bluetooth connection so where is all the data that was already transfered and how do i delete it?
can i pick up where it left off? if not why is it that i have to start over?
also it would be nice if the imac warned me of the file transfer when i try to put the computer to sleep. i put it to sleep out of habit right in the middle of a 3 hour transfer.

Large file transfer drop

Hello,
I cannot transfer large files from an iMac (Vista/Win7) to another windows share. I always get a disconnection at some point before it's done.
I have checked some older threads where an alternative broadcomm driver provided by HP did the trick. But those threads are rather old and the solutions suggested there are not working for me.
Any ideas?
Thanks.

Losing connection during call and get no reconnection for hours

Hi, I use my iphone4 (not iphone 4S) with ISO5 latest version. Since some weeks during calls I lose connection to provider and cannot reconnect to network. Restarting doen't help. After some hours the iphone get again connection not knowing what has happend. Losing connection happens while I'm on a fixed place (not travelling in a car or something similar) and making a call. It also happens at different places. Vodafone changed my SIM-card but it doen't help. I also backed-up and renewed the the iphone-software by using iTunes. The vodafone-support explained that with renewing the software a new software-patch will also be installed that should help. As you can imagine - I still have the problem! Who can help?
Thanks for answering!

#1 Did the problem start occurring after any particular weather event?
#2 What light turned/turns red?
#3 Do you have Voice service, and if so, do you have noise or static on the line while in a call that was never there before?
#4 Lastly, visit http://192.168.1.1/ and visit the System Status section of the ActionTec. Provide the Transceiver Statistics it shows.

P45 Neo2-FR hangs during large file moves

Hello all,
I have a newly built system that I moved my old XP install onto. ( Removed old Video and hardware drivers then did a repair install on the new hardware. ) That process appears to have been successful. The system runs normally most of the time, including resource heavy 3D apps like SecondLife. I have also accumulated over 32 hours running memtest86 with no errors found. ( a 24 hours session and an 8+ hour one. )
During the upgrade/rebuild I backed up almost 0.5TB of data onto an external drive and I'm not trying to move those files onto the new RAID array or a partition on the main hard drive. During any large copy operation, the system locks up. It's usually several minutes into the copy, and a hard reset is required to recover. The external drive is formatted to FAT32, so I've already addressed file size limitations as I copied the data to the external. The external drive is USB/Firewire/eSATA, but so far I've only used USB on the new hardware due to a lack of cables.
Anyone seen something like this before ? I'd really like to get the files back onto my internal drives. The external is a loaner from a friend, so there's a little time pressure. Any help will be appreciated.
Thanks
Todd

Update on this. I have not done a reinstall to date since I don't have a spare hard drive on which to do so.
However, I can eliminate a windows or driver problem from the list. I see exactly the same symptoms - random hangs of the machine - under Ubuntu 8 as well as windows. The Linux install is clean from a downloaded image and updated as recommended by the package manager.
It seems that the most likely time for the system to hang is during periods of intense IO activity. I had thought it was large file copies because that was what I was doing a lot of at the time of my original post.
I have tried moving my video card to the first PCI-X slot. No change.
I have removed 2 of the 4 memory modules, leaving 2x2Gb installed in bank 0. No change.
I have added extra fans - a large on on the side of the hard drive bay ( The case is an Antec Sonata III ) and a smaller fan aimed at the memory. No change.
I am using the J-micron Raid controller - is this still problematic ? I seem to recall some mentions of this.
Any suggestions to help isolate the problem would be appreciated.

SMB Network Drive not connecting

I have an SMB NAS drive that connected fine in 10.4. However, with 10.5, on my MacBook Pro I can connect to it and can see the 2 volumes on it but can't do anything with them, and can't disconnect from it once connected. On an iMac G5 also upgraded to 10.5, it starts to connect and then locks up. I can connect to the NAS with FTP with no problem but not through sharing.

Ok, I got it working at 3am last night, and I'm embarrassed to say how. Case sensitivity. My logins differ by the case of the first letter, so I used the syntax to add that and it worked. And I'd swear I did that already at some point, and/or when using the full mount syntax, so I don't know.
The thing that now ticks me off is, why did this all work fine in Tiger??? I have a theory which I won't get to explore until after work - perhaps the Keychain corrupted? I wonder since whenever I try mounting via the go menu (that still doesn't work, by the way), it prefilled my long name as the user. Now, logically, when I first connected months ago, I would have added the capitalized username in that dialog the first time and been done, which is why I took it for granted that it just would work. So now I'm wondering if no matter what I type, it's ignoring me and trying to log in with my long name from the go menu or the network thing in the finder. There have been some rumblings about some people's Keychains getting borked a bit, so maybe...
Strm, since you asked specifically, I was using (I hope this is right, I'm not on the Mac right now) mount_smbfs //User@machine/sharename /Volumes/whatever
If I'm wrong, the @ is a colon. It's annoying that there are all these subtle differences in syntax Also, when I trashed the volume in the UI, it seemed to automatically delete the directory I mounted to, so you may have to keep recreating it. Anyhow, that brings up something else interesting (or not)...I'm not having the IP problem...I can refer to my PC by it's network name in the command line no problem. I think that may be further evidence that my problems, at least, aren't in the smb setup per se, but in the Finder interaction.

Bandwidth control druing large file transfer

My user has an application that requires him to transfer hugh files from one location to another location.
our whole company is connected via ipvpn tunnel each office has a 20Mb ethernet WAN link.
when this user starts his file transfer, it will choke up the whole 20Mb in that particular office.
we have checked at the application layer, but there is no option to control the file transfer speed or bandwidth
is that any way, I can control the bandwidth usage of this user?

Your options for bandwidth control depend much on your platforms. Some devices would allow you to police or shape your traffic, but at Vasilii describes, probably the best solution would be to deprioritize this bulk transfer traffic using QoS. (For 20 Mbps, you might need a hierarchal shaper. Also for this to work well with Internet VPN, you cannot have anything else sharing Internet ingress.)
