Virus checking of large file
Just had a quick look at an email that was received today that had a large attachment. This mail was skipped 'cos of its size, but actually it contained a virus.
I guess this is expected behaviour?
Is that a way to change to that attachments are always checked for virus and keep the 'limit' for spam checking?
mmm... I regularly get those postcard.exe mails picked up by clamav.
More to the point, to test, I sent a 5M zipped attachment which contained an Eicar test virus and this got caught fine...

Hello,
I want to use the MD5 function to check very large files, but the Labview MD5 function does'nt return the same value as other programs on large files:
File master_ftyplavb.bin.tar.gz >> size (compressed 800MB) 897 435 615 bytes

MD5 with md5sums (Win7) 609e698b87e10ec4506e1eb465461d06
Is there an issue with this routine?
RegardsThe built in function is strictly written in LabVIEW, it may have something to do with your file size exceeding max for U32.
I've attached a VI that calls the .NET MD5 function to evaluate a given file name. (LV 8.6)
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T
If you don't hate time zones, you're not a real programmer.

IPod cyclical redundancy check/Parameter Incorrect error on large files
I’ve started getting errors on some large files (seemingly random) that I copy to my 5.5G 40GB iPod. (They’re .tivo files from my Tivo so I can watch shows on another computer, and my iPod is FAT32 used only with Windows.)
The files will copy without error, but then when I try to copy them off the iPod, on one system I’ll get a “cyclical redundancy check” error, and on another in the same spot with the same file I’ll get “Cannot copy <name of file>: The parameter is incorrect.
It seems to be happening just recently, and randomly. Maybe I’ll copy 8 shows over, and only one will give me that error.
When I get the error, the iPod’s disk activity indicator will have stopped spinning. It’s like it’s quit trying to transfer anything. I’ll get errors for a short while after that if I try to access anything on disc, but then it’s like the iPod wakes up again, the disc spins back up, and my computer can access files again.
I’ve restored my iPod recently, and run a basic check on the disk using Windows’ built-in disk utility.
Any other ideas what’s going wrong? Nothing’s changed about my systems since this started yesterday.I’ve started getting errors on some large files (seemingly random) that I copy to my 5.5G 40GB iPod.

While testing a MacBook pro in the Apple Store, I checked iPhoto. Looking at what was said to be 42Mb file I noticed that zooming caused immediate pixellation, so clearly a 42Mb RAW file was not what I was looking at. In my PS Elements on my PC when I zoom, the photo remains unpixellated until quite a lot of zoom is used (marked as 100%). This depends on the file size of the photo of course. Maybe the displayed photo in iPhoto is a low res. jpeg. This is not too good for me. I wanted to see how the base model of MacBook would handle photos esp large files and I need to zoom in. Will the base model cope with this in PSE for Mac?
iPhoto will happily zoom to 300%. The quality at that magnification will depend on the quality of the image. But if it's a sharp image - of any size - it will zoom to 300% with no problems.
PSE for Mac has nothing to do with iPhoto. I have used it with no problems, but for best information why not ask over at the Adobe forums? -
Can't download file - it's being Virus checked?
Hi,
I have a file in acrobat.com called 'vidplayer.zip' which I
cannot download. When I try to do so, I always get the page that
says "There was an error while processing your request: The
requested file is being
scanned for viruses.".
The file was uploaded a few days back but I still get this
message - any ideas?
Jamie.Hi Jamie,
At the moment, the easiest suggestion would be to try
deleting the zip from your share, re-uploading it, then seeing if
you experience the same issues.
If you still experience troubles after that, let us know and
we'll look deeper into the file and see what's causing the trouble!
Perhaps something happened (maybe an interrupted connection)
during the upload process and caused some troubles in the virus
scanning process.
Good Luck!
Best,

Downloading a specific file installs a keylogger not detected by virus checker
I recently downloaded "Optifine" for Minecraft from www.minecraftmine.org, and since then, every time I tried to log into any website, a window popped up asking me to enter my "password for the security software" - I thought this was due to me recently uprating my security settings in my virus checker (Trend Micro Titanium Maximum). The download was "powered by iLivid" and wanted to install a load of junk on my PC - I declined them all.
However, since then I found my profile got deleted from the forum I run, along with a few other member profiles, plus I've been unable to log into a few other websites I use as they say my password is invalid. Therefore I believe this iLivid install program is installing a key logger in Firefox (the security password box does not pop up in any other browser I have installed - I use them for testing my websites, but Firefox is my default browser).
I ran a full system scan using my virus checker, with nothing found apart from a few dodgy cookies, which were deleted. But the pop-up password box still persists in Firefox. The only way I removed it was to completely uninstall Firefox including all saves sites and preferences, and then re-installing Firefox (and now it's not asking me to enter my password anymore - even on sites I haven't visited in ages).
I'm now having to go through ALL my accounts to change their passwords (just to be on the safe side).
I will also be reporting this to Trend Micro, but as of yet they still don't have a compatible toolbar for Firefox :-(Hi there
I am glad you managed to resolve your issue. For future reference, you might want to take a look at this page: [[Troubleshoot Firefox issues caused by malware|Firefox issues caused by malware]] . It is also recommended to always download and install the latest security updates for optimum protection. -
I have 2 folders under Profiles with many files. The number of and larger files are slowing my virus scans. The 2 folders are 1enhkbms.default and heql0bzl.default. Can I remove one of these default folders and how do I determine which one along with how do I do it? Can I put limits on file sizes too, ie. the urlclassifier3.sqlite file is 56KB in each folder and the scan seems to slowly slug through it.
It may be better to adjust your virus scans so that they do not check Firefox as frequently.
urlclassifier has been involved in memory leaks in the past, but I am not aware it causes problems at present. The file is involved with Firefox's phishing protection. I am guessing that as it has lists of problem sites the file looks dangerous to your AV and maybe because of that takes longer to check than other files of a similar size.
Unless you have reset Firefox, or have multiple versions and thus multiple profiles a default install ordinarily has just one profile. I usually recommend users disable rather than remove any such unwanted additional profiles. Renaming or deleting profiles with profilemanager may be dangerous in that you may very easily''' stop Firefox from working &/or destroy all your personal information (passwords and bookmarks etc)'''
The default profile is called default. The actual folder itself is xxxxxxxx.default, the xxxxxxxx represents a pseudo random string added to make the folder name unique. You should be able to delete one of the profiles, but make sure it is the correct one. (I suggest initially manually renaming it rather than deleting it).
The easiest method of discovering the current profile is to use
* '''Firefox Button -> Help -> Troubleshooting Information -> <br /> [Show Folder]'''
On the other profile initially just rename it, add ''old'' in front of the name so it becomes ''oldxxxxxxx.default'' Once you are sure it is not needed you may delete it, and the best method to do that is by using the profile manager (remove the old from the name first) and be very careful that you delete the correct one. I suggest opening and trying each one first. NOTE profile names and folder names may not match. The safest method may be just to delete the folder manually.
(There is a file profiles.ini -- which should not be edited unless you know the rules it uses,-- that )

Does apple carry out a virus check remotely?
My Macbook is becoming very slow, I am constantly being requested for passwords for a variety of reasons mail, accountsd, and many more, i cannot open preview for some unknown reason. It is now driving me crazy. Any Ideas what is wrong? Whilst discussing this with my web designer he suggested a virus. I replied that Apples do not have virus attacks to which he replied that was a myth.
TomNo, they don't. It's your responsibility. Tell your web designer he hasn't a clue. There are no extant viruses.
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to: OS X Maintenance - MacAttorney;
The X Lab: The X-FAQs;
The Safe Mac » Mac Performance Guide;
The Safe Mac » The myth of the dirty Mac;
Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Under no circumstances should you install so-called maintenance software from MacPaw or ZeoBit (CleanMyMac/CleanMyDrive or Mac Keeper, respectively.) You do not need special software to maintain your computer.
Helpful Links Regarding Malware Protection
If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide and AdwareMedic.
Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
Fix Some Browser Pop-ups That Take Over Safari
Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
Quit Safari
Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
Relaunch Safari
If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

About file quarantine in OS X
If you require anti-virus protection Thomas Reed recommends using ClamXAV. (Thank you to Thomas Reed for this recommendation.)
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect everything targeting the Mac.
3. The very best way to prevent the most attacks is for you as the user to be aware that
the most successful malware attacks rely on very sophisticated social engineering
techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
your computer is intended to entice you to install their malware thinking it is a
protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
used to manage backups and to restore backups. Time Machine
requires a backup drive that is at least twice the capacity of the
drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file. -
Network speed affected by large file copy operations. Also, why intermittent network outages?
Hi
I have a couple of issues on our company network.
The first is thate a single large file copy imapcts the entire network and dramatically reduces network speed and the second is that there are periodic outages where file open/close/save operations may appear to hang, and also where programs that rely on
network connectivity e.g. email, appear to hang. It is as though the PC loses it's connection to the network, but the status of the network icon does not change. For the second issue if we wait the program will respond but the wait period can be up to 1min.
The downside of this is that this affects Access databases on our server so that when an 'outage' occurs the Access client cannot recover and hangs permamnently.
We have a Windows Active Directory domain that comprises Windows 2003 R2 (soon to be decommissioned), Windows Server 2008 Standard and Windows Server 2012 R2 Standard domain controllers. There are two member servers: A file server running Windows 2008 Storage
Server and a remote access server (which also runs WSUS) running Windows Server 2012 Standard. The clients comprise about 35 Win7 PC's and 1 Vista PC.
When I copy or move a large file from the 2008 Storage Server to my Win7 client other staff experience massive slowdowns when accessing the network. Recently I was moving several files from the Storage Server to my local drive. The files comprised pairs
(e.g. folo76t5.pmm and folo76t5.pmi), one of which is less than 1MB and the other varies between 1.5 - 1.9GB. I was moving two files at a time so the total file size for each operation was just under 2GB.
While the file move operation was taking place a colleague was trying to open a 36k Excel file. After waiting 3mins he asked me for help. I did some tests and noticed that when I was not copying large files he could open the Excel file immediately. When
I started copying more data from the Storage Server to my local drive it took several minutes before his PC could open the Excel file.
I also noticed on my Win7 client that our email client (Pegasus Mail), which was the only application I had open at the time would hang when the move operation was started and it would take at least a minute for it to start responding.
Ordinarlily we work with many files
Anyone have any suggestions, please? This is something that is affecting all clients. I can't carry out file maintenance on large files during normal work hours if network speed is going to be so badly impacted.
I'm still working on the intermittent network outages (the second issue), but if anyone has any suggestions about what may be causing this I would be grateful if you could share them.
ThanksWhat have you checked for resource usage during one of these copies of a large file?
At a minimum I would check Task Manager>Resource Monitor. In particular check the disk and network usage. Also, look at RAM and CPU while the copy is taking place.
What RAID level is there on the file server?
There are many possible areas that could be causing your problem(s). And it could be more than one thing. Start by checking these things. And go from there.
Hi, JohnB352
Thanks for the suggestions. I have monitored the server and can see that the memory is nearly maxed out with a lot of hard faults (varies between several hundred to several thousand), recorded during normal usage. The Disk and CPU seem normal.
I'm going to replace the RAM and double it up to 12GB.
Thanks! This may help with some other issues we are having. I'll post back after it has been done.
[Edit]
Forgot to mention: there are 6 drives in the server. 2 for the OS (Mirrored RAID 1) and 4 for the data (Striped RAID 5). -
Can't Copy Large Files To External Drive
This is driving me nuts. I'm running 10.4.11 with an external Newer Tech Ministack 320GB hard drive that's only ten weeks old. Yesterday I downloaded some large (50mb or so) QuickTime files to my desktop, which is to say my internal drive. I then tried to copy them to my external drive, since that's where I keep my movie files since they take up so much room. One copied over without any trouble, but numerous attempts to copy the others result in the process freezing after anywhere from 1/4 to 3/4 of the data has been copied, or else I get the "error 36" message. My first thought was that the external drive was failing, but I can copy small movie files (10mb or so) back and forth between the two drives with no problem. What's the point of having a large external drive if you can't use it for your large files? Repaired permissions on both drives, no improvement.
I have repaired permissions and run disk repair on the internal drive as well. Yes, I've played the clips in their entirety, but I'm going to do it again and look for any hiccups. That's an interesting theory and I want to check it out.
It has occurred to me that a workaround, although it by no means addresses the underlying problem, is to use QuickTime Pro to chop the clips up into several smaller files, copy them to the external drive, and then reassemble them via QuickTime Pro on the external drive.
FWIW, I neglected to mention (although I don't know if it's pertinent or not) that immediately after installing the external drive ten weeks ago I used SuperDuper to clone my entire internal drive onto the external firewire drive. I then erased the movies from the internal drive, which was bumping up against maximum capacity. I am able to boot from the external drive, and I want to retain this capacity should the internal drive (which is, after all, six and a half years old) fail. -
Beach Ball of Death on OSX while trying to upload large files(updated)
Hi,
I did a search on this and while I got lots of hits none on this issue.
We have a web portal that allows customers to upload files to a DAM server, we have control server.
The issue is not the back end, the back end is php and all set up correctly, we have 2gb ram assigned to php, the upload_max_filesize is set to 1.8gb max post size is set accordingly.
The flex app loads, user selects large file say 1.6gb ( we do file size check to make sure its below the limit), click upload button, beach ball of death shows, a little while later the file uploads.
Great so far, now the user tries another files same size, beach ball of death, script times out (we capture this and end gracefully). If the user restarts safari then the file will upload just fine.
Seems you can upload a large file first time and small files subsequently below 1.2gb, but you can not upload multiple large files.
Seems some sort of memory leak, I was looking at converting this upload app to send files via ftp, but if the flash player needs to process/load the files first then I don't think this will work looking to increase the file size ceiling to 4gb via ftp.
Code is a bit involved but in the end just calls file reference upload, then beach ball appears
Any ideas? player version 10.0.32.18 debug
UPDATED 09_17_09
It appears to be a memory leak in the player when in safari, the file is read but the memory not freed up after completion. Firefox frees the used memory after upload and you can continue. Not sure if Apple or Adobe issue.
However why bother reading the file first? can we have an HTP stream file upload in the web flash player like AIR as. This way the player would not care on the file size and the limitation would reside on the server, which we can deal with.

Airport Extreme, Airdisk, and Vista - large file problem with a twist
Hi all,
I'm having a problem moving large-ish files to an external drive attached to my Airport Extreme SOMETIMES. Let me explain.
My system - Macbook Pro, 4gb ram, 10gb free HD space on macbook, running latest updates for mac and vista, external hard drive on AE is an internal WD in an enclosure w/ 25gb free (its formatted for pc, but I've used it directly connected to multiple computers, mac and pc, without fail), AE is using firmware 7.3.2, and im only allowing 802.11n. The problem occurs on the Vista side - havent checked the mac side yet.
The Good - I have bit torrents set up, using utorrent, to automatically copy files over to my airdisk once they've completed. This works flawlessly. If i connect the hard drive directly to my laptop (macbook running bootcamp w/ vista, all updates applied), large files copy over without a hitch as well.
The Bad - For the past couple weeks (could be longer, but I've just noticed it recently being a problem - is that a firmware problem clue?) If i download the files to my Vista desktop and copy them over manually, the copy just sits for a while and eventually fails with a "try again" error. If i try to copy any file over 300mb, the same error occurs.
What I've tried - well, not a lot. The first thing i did was to make sure my hard drive was error free, and worked when physically connected - it is and it did. I've read a few posts about formatting the drive for mac, but this really isnt a good option for me since all of my music is on this drive, and itunes pulls from it (which also works without a problem). I do however get the hang in itunes if i try to import large files (movies). I've also read about trying to go back to an earlier AE firmware, but the posts were outdated. I can try the mac side and see if large files move over, but again, i prefer to do this in windows vista.
this is my first post, so im sure im leaving out vital info. If anyone wants to take a stab at helping, I'd love to discuss. Thanks in advance.Hello,
Just noticed the other day that I am having the same problem. I have two Vista machines attached to TC w/ a Western Digital 500 gig USB'd. I can write to the TC (any file size) with no problem, however I cannot write larger files to my attached WD drive. I can write smaller folders of music and such, but I cannot back up larger video files. Yet, if I directly attach the drive to my laptop I can copy over the files, no problem. I could not find any setting in the Airport Utility with regards to file size limits or anything of the like. Any help on this would be much appreciated. -
Copying large file sets to external drives hangs copy process
Hi all,
Goal: to move large media file libraries for iTunes, iPhoto, and iMovie to external drives. Will move this drive as a media drive for a new iMac 2013. I am attempting to consolidate many old drives over the years and consolidate to newer and larger drives.
Hardware: moving from a Mac Pro 2010 to variety of USB and other drives for use with a 2013 iMac. The example below is from the boot drive of the Mac Pro. Today, the target drive was a 3 TB Seagate GoFlex ? USB 3 drive formatted as HFS+ Journaled. All drives are this format. I was using the Seagate drive on both the MacPro USB 2 and the iMac USB 3. I also use a NitroAV Firewire and USB hub to connect 3-4 USB and FW drives to the Mac Pro.
OS: Mac OS X 10.9.1 on Mac Pro 2010
Problem: Today--trying to copy large file sets such as iTunes, iPhoto libs, iMovie events from internal Mac drives to external drive(s) will hang the copy process (forever). This seems to mostly happen with very large batches of files: for example, an entire folder of iMovie events, the iTunes library; the iPhoto library. Symptom is that the process starts and then hangs at a variety of different points, never completing the copy. Requires a force quit of Finder and then a hard power reboot of the Mac. Recent examples today were (a) a hang at 3 Gb for a 72 Gb iTunes file; (b) hang at 13 Gb for same 72 Gb iTunes file; (c) hang at 61 Gb for a 290 Gb iPhoto file. In the past, I have had similar drive-copying issues from a variety of USB 2, USB 3 and FW drives (old and new) mostly on the Mac Pro 2010. The libraries and programs seem to run fine with no errors. Small folder copying is rarely an issue. Drives are not making weird noises. Drives were checked for permissions and repairs. Early trip to Genius Bar did not find any hardware issues on the internal drives.
I seem to get these "dropoff" of hard drives unmounting themselves and other drive-copy hangs more often than I should. These drives seem to be ok much of the time but they do drop off here and there.
Attempted solutions today: (1) Turned off all networking on Mac -- Ethernet and WiFi. This appeared to work and allowed the 72 Gb iTunes file to fully copy without an issue. However, on the next several attempts to copy the iPhoto and the hangs returned (at 16 and then 61 Gb) with no additional workarounds. (2) Restart changes the amount of copying per instance but still hangs. (3) Last line of a crash report said "Thunderbolt" but the Mac Pro had no Thunderbolt or Mini Display Port. I did format the Seagate drive on the new iMac that has Thunderbolt. ???
Related threads were slightly different. Any thoughts or solutions would be appreciated. Better copy software than Apple's Finder? I want the new Mac to be clean and thus did not do data migration. Should I do that only for the iPhoto library? I'm stumped.
It seems like more and more people will need to large media file sets to external drives as they load up more and more iPhone movies (my thing) and buy new Macs with smaller Flash storage. Why can't the copy process just "skip" the parts of the thing it can't copy and continue the process? Put an X on the photos/movies that didn't make it?
Thanks -- JohnI'm having a similar problem. I'm using a MacBook Pro 2012 with a 500GB SSD as the main drive, 1TB internal drive (removed the optical drive), and also tried running from a Sandisk Ultra 64GB Micro SDXC card with the beta version of Mavericks.
I have a HUGE 1TB Final Cut Pro library that I need to get off my LaCie Thunderbolt drive and moved to a 3TB WD USB 3.0 drive. Every time I've tried to copy it the process would hang at some point, roughly 20% of the way through, then my MacBook would eventually restart on its own. No luck getting the file copied. Now I'm trying to create a disk image using disk utility to get the file from the Thunderbolt drive and saved to the 3TB WD drive. It's been running for half an hour so far and appears that it could take as long a 5 hours to complete.
Doing the copy via disk image was a shot in the dark and I'm not sure how well it will work if I need to actually use the files again. I'll post my results after I see what's happened. -
Privileges problem when transferring large files
This just happened, and I don't know what changed. I cannot transfer large files from my Macbook Pro to my MacPro desktop, neither on the network nor by a USB hard drive. I get the infamous "You do not have sufficient privileges" message. The files start copying, and after about 1gb or so, the message pops up. Small files no problem, there's no restriction on those. It does not matter which disk I am trying to copy it to.
I thought it was just a problem with iMovie files and folders (these get big fast), but it seems to be an issue with any large file. I have repaired permissions on both disks, I have made sure that the unlock key is unlocked and that all the boxes are checked "Read & Write".
And this problem just arose today. Nothing has changed, so far as I know.I assume I am always logged in as administrator because I have never logged in as anything else. It also does not matter from what folder, or even disk drive, I am trying to transfer from. If the file is above a certain size, it stops transferring and I get the error.
What interests me is not that I immediately get the "insufficient privileges" error when I try and transfer a forbidden folder or file. I've seen that. This happens after about a gig of data has transferred over already, then that error pops up. -
Copying large files hangs at "less than a minute"
hi,
When copying large files around my intel mac mini system the Finder appears to freeze just before the end - when the dialog window is telling me that there's "less than a minute" left. It doesn't happen ALL the time, just enough times to be a real nuisance.
Killing the finder doesn't help - I need to power off to regain control of the Finder.
This recently started to happen after I opened up the mac mini to add more memory. Not sure if this is related - everything else seems to be ok. I have a mixture of USB and Firewire external drives - the mac mini is used to hold all my HD camcorder files and process the iMovie rendering to disk.
I'm running the latest version of os x with all the updates.
Any suggestions?

Mac Intel Mini Mac OS X (10.4.8)Hi,
Hello! It's likely a firmware issue with an external
drive. Check the ext drive's site to see if there's a
firmware upgrade. Tom
Thanks for the reply Tom. I've downloaded a firmware updater from the Lacie site, and I'm apparently uptodate. However, I also have a USB Seagate external drive, but the Seagate site seems to only provide support for Windows. grr.
Is this a known problem with certain drives/firmware?
thanks,
