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.

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?

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,

How can I copy mp3 files from my Itunes library to an SD card for use in a non-apple phone?

How can I copy mp3 files from my Itunes library to an SD card for use in a non-apple phone? I can physically copy the tunes as mp3's but the phone does not seem to be able to play all of them. Do I need to copy an entire album or can I just pick & choose individual songs? The phone is question is an LG running who knows what for an operating system.

AAC is Advanced Audio Coding. Basically it's a format that sounds better than MP3 but doesn't take up as much space as a lossless format (like you'd have on a CD). More than likely you've had that encoding turned on when you ripped your music into itunes (it's the default encoder). Therefore your LG phone won't play them.
You need to turn off the AAC format by going to the iTunes menu, Preferences, General (at the top), then clicking the "Import Preferences" button. Change the AAC Encoder to MP3 Encoder. After that you'll have to make MP3 copies of your songs by right clicking them and selecting "Create MP3 Version." You'll get a copy of the song that should transfer to your SD card and have MP3 encoding. Hopefully your phone will play that.

Can you copy/paste files from the Finder to Mail in Lion, or drag them onto the Mail icon in the Dock to create a new message and attach the files to it?

Message title says it: Can you copy/paste files from the Finder to Mail in Lion, or drag them onto the Mail icon in the Dock to create a new message and attach the files to it?
I can't find anything in the Knowledge Base that says these two options no longer work or still do.
I do not have a system capable of running Lion, but I need to know the answer nonetheless.

Gee, I don't know: "paste attachments mail Lion"? ;-)
One further question, if I may: in Panther (which is where I've aggregated nearly 7 years of mail), if you copy more than one file in the Finder, switch to Mail, and paste the files into a new message, only the file names paste in. If you copy one file and paste it into a Mail message, you get the file, not just the name. Is that still true, or has that (IMHO) bug been fixed since 10.3.9?

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.

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.

Can't copy large files to AirPort Disk Using Windows 7

Hi Everyone,
I'm positng because I'm unable to copy large files to an AirPort Disk using Windows 7. I have the following setup.
AirPort Extreme:
- Firmware version: 7.6.1
- Airport disks secured by password
- No guest access allowed
- Airport Disk Preferences:
- Automatically discover airport disks is enabled
- Show Airport Disks in the system tray is enabled
External Drive:
- Western Digital 500 GB MyBook External Drive connected to Airport Extreme thru USB
- FAT32 Formated
Computers:
- 2 Toshiba Proteges, Both with 4GB RAM
- Both have Windows 7 Home Premium with Service Pack 1, 64-bit version
- (Sorry we have no MacBooks at home, just iPhones and iPods!)
Airport Utility:
- Version 5.6.1
Airport Disk Preferences Utility:
- Version 1.5.5.3
A week ago, I was able to copy over large files (videos <4GB in size) to the drive. Now, when I try to copy over these large files to the drive, the copy dialog box hangs. I receive a message stating that Windows is calculating the size, but then it doesn't copy over. Windows then gives me a message that it is unable to copy to the drive. When I test the drive connection by copying a small text file over, it copies over quickly and seamlessly. This problem occurs on both computers.
I am able to do the following with the drive connection:
- Read files
- Change file names
- Copy files from the drive to my computer
- See the contents of drive
I've tried all the combinations of the following with no success:
- Turning off Windows Search
- Downgrading the firmware
- Reconfiguring wireless adapter
- Rebooting computer
- Rebooting wireless router
- Rebooting external drive
The drive seems to be working fine except for when I want to copy <2GB files over to the drive. Does anyone have a solution that seems to work?
Thanks!

I'm happy to report that, after reformatting the drive to HFS+ (aka Mac OS Extended), there are no problems writing/copying large or small files to the AirDisk drive. I'm also happy to report that I am copying to the drive at a rate of roughly 4MB/s.
As I mentioned earlier, the only catch is that I am unable to plug the external drive directly into a Windows computer via the USB port as Windows is unable to read HFS+ formatted drives. (I can, however, plug the drive into a Mac computer as they can read HFS+ formatted drives. The only problem is that I don't own any Macs at this time! LOL!)
You're probably wondering how I formatted the external drive to HFS+ since I don't own any Macs. (Windows only allows you to format drives in exFAT, FAT, NTFS and the like.) That is a good question. Basically, I downloaded an open source formatting tool called, Gparted, which allows you to format any USB drive to any major file format system. Since Gparted is an open source tool, it is a little cumbersome to use. Once you figure out how to use it, it is a cinch to format the drive to HFS+. (Of course, an easier method would be to borrow a friend's mac, plug the drive into their mac, and format it to HFS+ using their mac.)
For a step-by-step guide on how to solve this problem, see the steps below:
1) Backup all data from external drive
    a) Fortunately, I have a 1TB ultraportable USB drive which has enough space to backup all data on the drive
2) Format the external drive to HFS+ using one of the methods below
    a) Plug it into a Mac and format it
     b) Use Gparted (free) to format it
3) Plug the drive back into the Airport Extreme
4) Start copying files over to your networked drive!
I hope this helps you! Cheers!

Can't copy all files from a CD-R

I have a number of CD-Rs of family photos. I made the disks on a Dell PC with a horizontally mounted CD-RW Drive in 2005. I recently tried to load them onto my iMAC, but I could only copy about half of the files before the drive hung-up. The drive would often make noise and then slow to a near inaudible crawl and then say the file(s) could not be copied.
I was able to copy the missing files to a memory stick at a local library on an HP PC with a horizontally mounted drive, so the disks are OK. Interestingly, I had trouble with the disks at a library with iMAC-like HP PCs, i.e., all-in-one monitor/pc/optical-drive with a vertically mounted drive.
Other drive-related problems: (1) friends have trouble playing Audio CD-Rs I've made for them, (2) I can't copy a DVD-R with MackTheRipper (PowerPC), the DVD-R plays fine.
Is this a drive issue, a drive orientation issue, or something else?
Thanks for your help.

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.

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:

Can't copy some files from Windows 7 to Mac OSX over network

Hi,
I'm running the latest version of Max OSX v10.8.4 on a brand new Macbook Pro.
I have followed the setup instructions at http://www.7tutorials.com/how-change-workgroup-mac-os-x-easy-networking to access my Macbook from Windows, and http://www.howtogeek.com/howto/24950/how-to-share-a-folder-in-os-x-with-windows/ to share some folders from my Macbook to Windows.
I am now trying to copy some files from my Windows 7 Pro (SP1) computer to my Mac, and have hit the following problems:
I can view my Macbook in my list of local networked computers on WIndows, but I cannot access it. Clicking on it causes Windows 7 to try and access it, but then I get a message after a minute saying the network path could not be found. However, if I manually enter the IP address of my Macbook in the Windows address bar (\\192.168.0.191), I can view and access all the shared folders. I can never access the Macbook via it's computer name (\\MACBOOK-ROB).
I cannot copy some files from Windows to my Macbook shared folders via Windows. There is nothing to distinguish these files from the hundereds of other files that I have successfully copied to my Macbook. They are pictures and music with no special characters in the filenames, not overly long filenames or folder paths, no access restrictions, or any other security restriction that I can see. However, every single attempt to copy these files to my Macbook results in WIndows reporting that access to the destination was denied.
I have tried both these above scenarios on WiFi and Ethernet, and the results are the same.
So:
Why am I unable to access my Macbook by it's computer name on the network? How can Windows see it, but not access it?
What are the limitations on transferring files over SMB that is (presumably) causing these specific files to fail?
Thanks for any help you can offer.

I have a fix for inability to copy files. I had the same problem moving a lot of old files across my LAN from a Windows XP machine to a Mac Mini running Mountain Lion. After confirming copy of some special file, I would get an error that terminated the copy operation, and info on the Mac side would show a locked folder.
I finally decided to eliminate all special files on the Windows side, before copying, by running
attrib -s -h -r /s /d [drive or folder]\*.*
in a command window. Running attrib /? tells what the arguments mean, but it doesn't explain that you need the *.* to make the command go through the hierarchy clearing the special attributes on all the files.
After I did that, and then used drag and drop between two Windows Explorer windows (one on the Windows drive, on on the target drive on the Mac), the whole move operation ran to completion without stopping either for error or to ask for confirmation.
I do not have a fix for the inability to access some computers by name rather than by IP address. I'm looking into the possibility of activating bind on the Mac but I haven't done anything yet.

Can't copy large files to NAS

I have a Cirago USB NAS adapter that I have one 120 GB external drive connected to.
The external drive is FAT32 formatted.
I can connect to the drive just fine and can copy small files to it without a problem.
When I try to copy larger files to it (~700 MB or greater) it gives me an error saying there isn't enough space on the drive.
The drive has over 40 GB of space available though.
Not sure what the heck is going on...

I ended up having to connect to the NAS differently.
The nas automatically showed up in the Finder when I started it up for the first time.
It just showed up as "nas"
Well, I needed to go to the Go menu in finder then click "Connect to server"
I then had to enter a specific address
http://nas.local:9880
It then asked for login credentials.
The only difference is it connected via WebDAV this time around.

Can't copy multiple files from compact flash via USB3

Problems on MacBook Pro Retina 15-inch with Mavericks installed...
I am not able to copy multiple files from an attached Lexar USB3 Compact Flash reader (card is 128GB Lexar UDMA 7 compliant). Files are video files and when I try to copy more than one at a time the screen of my MacBook Pro flashes "off" and back "on" and the copy process ceases...
Any fixes for this???

See: https://discussions.apple.com/thread/5471050?tstart=60
Update the firmware of your USB 3.0 card reader. It's weird to think there is firmware on the thing, but it worked for me!
