Finder Freezing During Network File Transfer

I have 2 external G-Drives daisy chained via FW800 on another Mac in the house.  Sometime when I try to look at the drive in finder from another computer on the network Finder freezes.  All I can do is a forced renoot and then things are back to normal.  Sometimes this happens when I try to look at the second hard drive in the daisy chain or during file transfers I will get an error code - 50.
Again after a reboot things are normal again, but it happens more often then not.

Just did that this morning, and it made know difference. 
After computer goes to sleep if I wake it up via the network drive 1 loads and 2nd daisy chain drive kills finder.
System reboot fixes it.

  • Windows 7 network file transfer absurdly slow

    I know there are plenty of other posts about slow network file transfer. Here, elsewhere, I can't say I read them all but most are referring to slow down to 1MB/s.
    I am getting <20KB/s.
    If I transfer a very small file (less than 100KB) it would start quickly then slow down to <20KB/s. all subsequently network file transfer would be slow, a reboot is needed to reset this. If I transfer a large file it would be stuck on calculating for
    a long time and then begin with <20KB/s immediately.
    This is a fairly newly built desktop. Realtek gigabit on-board LAN of ASRock Extreme3 gen3. I have tested network file transfer to and from a Windows 7 laptop and a MacBook Pro, so I am fairly certain it is the desktop's problem. The slow speed only happens
    with one direction, outbound from the desktop, regardless of whether I initiate the file transfer action from the origin or the destination. Inbound network file transfer and internet speeds are fine, so I don't think this is a hardware issue.
    Remote Differential Compression is off. Drivers are up-to-date from ASRock's website. I am getting 74.8MB/s internet upload speed from speedtest.net (http://www.speedtest.net/result/1852752479.png). Inbound network file transfer I can get around 10-15MB/s.
    I looked everywhere and can't find symptoms that fits my case well. I'd be cheering if I can get 1MB/s. Well, maybe not, but at this point it is more efficient for me to upload everything to the Internet and download them again than to use local file transfer,
    which is just absurd.
    I am hoping this community has some insight for me to troubleshoot this. I don't see anything obviously related from the Event Viewer, and beyond that I just don't know where else to look.
    Any suggestions are greatly appreciated, thank you in advance.

    Hi,
    Firstly, would you please try again to install the HotFix instead of disabling TCPAuto-Tuning and Windows Scaling heuristics via netsh manually.
    If issue persists, please try following:
    1. Test the issue in Safe Mode with Networking.
    2. Disable "Large Send Offload".
    How to:
    1) Open an elevated command prompt and press Enter:
    netsh int ip set global taskoffload=disabled.
    2) Disable and re-enable the network interface or reboot your system. 
    3) Run the following command in an elevated command prompt to confirm the command above is successful:
    netsh int ip show offload
    3. Check the value of “Speed & Duplex” is Auto in Advanced Properties of the NIC. If not, please let us know your value.
    4. Check if “Flow Control” is disabled in Advanced Properties of your NIC.
    5. Go to your Start Menu, search for “Local Security Policy“ and run it as administrator. Under Security Settings -> Local Policies -> Security Options.
    1) Open “Network security:Minimum session security for NTLM SSP (including RPC based) Clients”,
    unselect “Require NTLMv2 session security” and “Require 128-bit encryption”.
    2) Do the same operation to “Network security:Minimum session security for NTLM SSP (including RPC based) Servers”.
    3) Open
    the policy “Network Security LAN Manager authentication level“. Locate and select the option “Send LM & NTLM – use NTLMv2 session security if negotiated“. Click Apply, and close out of all
    policy management windows.
    Hope this helps.

  • NIO Network File Transfer Seriously Underperforming

    I've written a networked collaboration tool that implements client/server file transfer, and exhausted every NIO I/O option I can think of, yet my file transfers continue to run quite slowly on a 100-BT LAN.
    All SocketChannels are set to NON-BLOCKING mode. I started with FIleChannels and ByteBuffers using the following server code:
    // file transfer is running in its own thread
    File = new File(filePath);
    RandomAccessFile inputFile = new RandomAccessFile(file, "r");
    FileChannel fileChannel = inputFile.getChannel();
    ByteBuffer bb = ByteBuffer.allocateDirect(8192);
    int bytesRead = 0;
    while( fileChannel.read(bb) != -1 ){
         bb.flip();
         channel.write(bb);   // channel is the client SocketChannel
         bb.compact();
         Thread.sleep(20);
    }The client side code is basically the same. This implementation transfers to the client at about 500k/second. Next I tried using a MappedByteBuffer to map the file into memory on the server:
    File = new File(filePath);
    RandomAccessFile inputFile = new RandomAccessFile(file, "r");
    FileChannel fileChannel = inputFile.getChannel();
    MappedByteBuffer mbb = fileChannel.map(FileChannel.MapMode.READ_ONLY, 0, fileChannel.size());
    while( mbb.remaining() > 0 ){
         channel.write(mbb);   // channel is the client SocketChannel
         Thread.sleep(20);
    }The MappedByteBuffer actually works quickly, but only for small files. I can transfer an MP3 file in less than one second. This is the kind of performance I'm looking for. I can get 100-BT speeds on 10 or 20MB files. However, if I attempt to transfer a large file (500MB) using this method, I get the following exception calling channel.write(mbb):
    java.io.IOException: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
    I'm assuming this is because the call is attempting to write far too many bytes to the client SocketChannel, but I thought SocketChannel.write() would only write as many bytes as possible to a non-blocking SocketChannel, so I'm a bit confused as to why it would overflow the SocketChannel's buffer.
    I tried one more implementation, using FileChannel.transferFrom and TransferTo. Here's the code on the server side:
    File = new File(filePath);
    RandomAccessFile inputFile = new RandomAccessFile(file, "r");
    FileChannel fileChannel = inputFile.getChannel();
    long written = 0;
    long fileSize = fileChannel.size();
    while( (written += fileChannel.transferTo(written, 8192, channel)) < fileSize ){
         Thread.sleep(20);
    }This performs slightly faster than the first implementation using FileChannel and ByteBuffer, but only by 1MB/second or so on LAN. I changed the code to
    fileChannel.transferTo(written, fileSize, channel)But I get the same exception during runtime:
    java.io.IOException: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
    So... I'm lost as to how to get acceptable LAN performance on a network file transfer. If the MappedByteBuffer implementation didn't throw an exception, then I'd be set. But I have no idea what is causing the exception and cannot locate any information on it.
    Any input or suggestions would be greatly appreciated. Thanks much!

    A point of interest? When you tried the
    fileChannel.transferTo(written, fileSize, channel)
    and got the IOException (buffer too small etc) where you using non-blocking IO? If so try it with the Socket
    Channel set to Blocking mode (might help to narrow down the problem)
    Also have you checked the CPU usage of your program when its transfering data?
    as pkwooster said it could also be an issue with diskIO. There are many free apps on the net that will
    measure the throughput your hardisk can sustain.

  • Finder Freeze while copying files

    Hi,
    Recently my Finder freezes whenever I transfer big files (more than 1 gig) to my server through network. The Finder would freeze for 10 to 20 seconds and the copying bar freezes too. After 10 to 20 seconds, the copying bar continue to copy the remaining and the Finder back to normal. I am using Mac OS X 10.6.7. I have formatted and install the Snow Leopard installation disc and it seems ok but after I upgrade to 10.6.7. The problem comes back. Please share if there is any solution. Thanks.

    Can you try FTP. It is a just try and narrow your problems. Also can you access via a browser. I take it that they are mounted on a router, which one. Finally, are you having problems with smaller files on both AFP and SMB.

  • Finder windows not opening, file transfer box not showing.

    If I go to open Finder from the dock, or using Command + N a new window doesn't open, I have to open it using harddrive icon off my desktop. Also, when transferring files from drive to drive (either on my computer or across the network) the box showing how far the transfer has progressed doesn't turn up. These are causing me significant problems, so if anyone can help that would be hugely appreciated!
    Oh, as I've been writing this about 30 finder windows opened at once, so it appears soemthing is delaying the response, although not regurlary, as they all opened at once. They do now open but the file transfer isn't showing still. My computer has been on an hour and a half for finder to sort itself out, it's ridiculous!

    Hi MLansdell, Welcome to Apple Discussions.
    Create a new account, name it "test" and see how your Finder works in that User acct? (That will tell if your problem is systemwide or limited to your User acct.) This account is just for test, do nothing further with it.
    Open System Preferences >> Accounts >> "+" make it an admin account.
    Let us know and we'll troubleshoot this further.

  • How to increase the speed of network file transfer

    hi ,
    In my application i want to use the file from one system to another system.
    i am using stream reader to get the file over the network , its working fine for small file,
    but i want to access file size exceed 10 MB then i faced the problem. Its get very slow the file transfer over the network.
    so i am try to use java NIO for transfer file,
    Using NIO , While i am make server and client both are same system then the file tranfer is 10MB file in 10 seconds , but i am making server and client are different machine then its take so long to transfer file ie (10 MB file in 3 minutes).
    I want to reduce the time . If any chance to reduced the file transfer time then please suggest me.

    Data transfer rate for a single client is unlikely to be effected by using NIO or old blocking IO. The important factor is the maximum transfer rate you can get between the sender and receiver.
    You should be able to get 0.5-1.0 MB per second for each 10 Mbit per second of available bandwidth. Your timings suggest you are getting about a 10-20 Mbit/s link speed.

  • Finder freezes after multiple file copy

    Hi!  I recently bought an external hard disk drive (1TB) and had it formatted for use of the Mac.   I copied all the files in my All Images folder to the HDD by selecting all the files and dragging to the HDD.   However, it seems to have copied/duplicated the files in the same folder.   Now Finder freezes (the rainbow pinwheel keeps appearing).   I am still able to do some keyboard shortcut functions -- to shut down and restart only.   I tried to open in safe mode and go to Finder's Go tab but couldn't find the Libraries folder so that I could delete com.apple.finder.plist (I googled this solution).   Help please.

    I figured it out, it's so bizzare. I realized that for all of the problems I was having, the hang up occured right before the computer was supposed to play a sound. Anyway, I looked through my sound preferences and discovered my alerts were set to go to my jawbone headset, which I only connected to my computer a couple of times, but that was months ago. Anyway, I changed that and all seems well now. All I can assume is that the OS sees the sound is supposed to go to the headset, sees the headset isn't active (or connected), so it tries to connect and activate (which it hangs the app for), and that times out, at which point it routes the sound through the system speakers. This issue is probably uncommon, but doesn't seem to be anything unfixable.

  • 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.

  • Finder freezes and Networking and Locked drives will not unlock

    I have been having trouble with my Mini'S finder freezing when I try to connect to another computer. Sometimes it works OK but it often freezes, beachball and cannot relaunch finder, have to reboot. The mini is Intel Duo, Network is 6 windows machines and 1 g5 PPC 1.8 single. An Apple Airport Extreme, a Linksys router and a Buffalo router, I can connect to the Win machines no problem but , like I said, often when connecting to the G5 I get the Finder Crash, but only about 60 % of the time. I have sharing turned on, Personal and Windows on both machines. I am admin on both. Also the MINI drops Network connections which have been working for a few hours.
    I am beginning to think the MINI's Network card is bad.
    ANother maybe related issue, from the MINI, 2 drives on the G5 appear as Locked, I have repeatedly unlocked them with Xray and by the terminal, from the G5 (to which the drives are attached) the drives show unlocked but always from the mini they appear as locked. I have tried to unlock them form the MINIS terminal but get a long Beach Ball.
    Both the G5 and Mini are running the latest OSX and everything else is updated.
    Anyone else relate to these issues? thank you,

  • Freeze during large FW transfer from WD

    Just got my second MBP and having issues with freezing while doing FW transfer. System would lock up after about 20 - 30 minutes of transfer. Saw this with Finder, iTune, and Time machine. Never happened with my other MBP which is 13" unibody. So, I know my WD is fine. Both running latest version of Snow Leopard. Really annoying to see this after spending so much money on it. Has anyone seen this problem before? I have read some issues surrounding FW, but they don't seem to relate to what I am experiencing.
    Many thanks in advance.

    No. I don't have another FW ext HD. I am starting to hear lot of WD issue and planning to buy some Lacie. Odd thing is I never had the problem with my 13". Concern I have is that the laptop gets really hot by the left side (assuming where HD and FW board is). Read some stuff about graphicboards getting overheated and could freeze up the machine. Also, found very very long forum trail about the freeze up of new i5 and i7 MBPs. fortunately, i haven't experience any other issue beside the FW lock up. So, i am still happy with the purchase, but still worried...

  • Very slow network file transfer speeds

    We just moved and I've now connected our imac and macbook to our network.  This time rather than running cables I thought we'd run the imac and the macbook off of our airport extreme.  After a bit of repositioning and fiddling I've got a strong signal throughout the house and the internet connection is great.  The problem I'm having though is network file transfers are really, really slow.  I can't get anything over 2MB/sec on either mac, and it is way slower on the macbook than it was previously.  From NetStat it looks like there are some bad connections and overflows, is there anything here that might point to a problem?  Thanks in advance for any suggestions.  NetStat results for tcp:

  • 10.2.8 locks up during network file sharing

    Hi all,
    I am running 10.2.8 on a beige G3 with an Apple 100-T ethernet card. I am trying to copy files from one mac to another using file sharing. The destination mac is running 10.3.9. From the destination mac, I connect to the source mac. I select a set of files on the source mac, about 3 GB, and drag it to the folder on the destination. It works for about a minute, then the source mac locks up. The display goes blank and the monitor goes to sleep. Reboot is the only thing that brings it back.
    In /Library/Logs/AppleFileService/AppleFileServiceError.log I find:
    !!Log File Created On: 1/28/2006 2:13:23 27:6:0 GMT
    28/Jan/2006:02:13:23 -0600: Server shut down.
    28/Jan/2006:13:59:48 -0600: AppleTalk Listener closed because of ATalk error
    28/Jan/2006:14:47:24 -0600: Appletalk service couldn't be enabled.
    Seems like about the right time of day, but it doesn't tell me anything that would help solve the problem.
    Thanks,
    Scott

    Update - Here's what I've tried so far, none of which has had any effect:
    - Turned off AppleTalk since it is off on another 10.2.8 system that does work.
    - Tried both ethernet ports: 100-T PCI and 10-T built-in.
    - Tried different port on Linksys router.
    - Tried installing 10.2.8 combo again (already running 10.2.8)
    - Tried ssh from another mac to verify that it really is crashing - it is.
    The most I get to copy is about 400 MB, frequently much less. I doubt that it fails on the same file each time, but I haven't been paying that close attention.

  • 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.

  • Finder freezes when copying files to an external USB drive

    I am copying video TS folders from my Mac Pro to a USB 3.0 drive, and Finder keeps freezing up. Oddly, it doesn't always happen, and it doesn't seem to be the amount of data--I've successfully copied 32GB at once, and had Finder crash trying to copy 6GB. Other details: the external drive is brand-new, and set up for OS X, I have repaired the permissions on the Mac's drive and just for kicks did the same on the Seagate USB drive. I was originally copying the files from a folder I had on the desktop, and read here that the desktop being involved in the equation is a Finder-killer, so I moved the files to a different folder. I have done this a lot in the past to a different drive with no problems whatsoever. Lastly, when this happens, all I can do a hard restart. Everything is fine when it starts back up, but after a dozen restarts in a day, I'm about to shoot myself.

    Well, I can tell you this
    Mac's can't use USB 3 so it's dropping to USB 2
    If it's port powered, it could be drawing too much power and the Mac is cutting it off, use a powered USB hub.
    If the external drive is formatted MBR with FAT32 (MSDOS) then that's a issue with over 4GB sized files, you need exFAT or HFS+
    You may nee dot remove all data and Zero Erase the entire drive to map off bad sectors and before each time you copy a huge amount of data (if it hasn't ben done in the last 6 months) this catches new failing sectors.

  • Very slow network file transfer speeds with WRT310 + Powerline PLS300

    Hi guys-Thanks for looking!
    I have Charter hi-speed (10MBS) with my wireless N router (WRT310).  Connected to my router is the PLE300 Linksys powerline adapter.  I have two PLS300 powerline adapters.  One feeds my computer and my wife's computer in the den and the other feeds the playstation, xbox, NAS Black Armor media server in the media room. 
    In running speed tests online, I get >10 MBS on both ends of the powerline adapters so surfing the internet is very fast on both ends.  I also have very fast file transfers from my wife's computer to my computer across the same PLS300 adapter
    However, in transfering files to my media server from my computers, I get speeds of 500 kbs.  If I try to stream video files (non-HD) to my PS3, the video stutters to where it is unwatchable.  I have also tried to bypass the powerline adapter by just using a wireless N gaming adapter and that yielded similar slow results.
    I am running Windows 7 on both computers.  I have removed the firewalls and McAfee. 
    Again, thanks for looking and happy new year!

    Reduce the MTU to 1350 on the router and check if that helps...
