OS X :: Copying Large Files From A Bus Powered USB External?

Jun 18, 2008

I think I have found a bug in Finder where I cannot copy large files from a bus powered USB external. I get this error:

"The Finder cannot complete the operation because some data in "..." could not be read or written (Error code -36)"

I think I have eliminated hardware as an issue:

1. The problem is repeatable (and always happens) on my Intel Macbook Pro, Intel Mac Mini and G4 Mac Mini

2. The problem happens whether I have formatted the external as HFS+ or NTFS (I can't use FAT32 for files over 4GB, e.g. VMWare disk images)

3. I can copy the files off the external with my Windows Vista machine (mostly dormant these days) and an XP laptop (I use for work), using Explorer.

4. The same problem happens with two different external enclosures (An Xtatix Portadrive and a Beyond Micro mobile Disk). I have also tried 3 different 2.5" drives in these enclosures.

5. If I boot my Macbook Pro into Vista using Bootcamp, I CAN successfully copy the files using Explorer.

6. I CAN also copy the files OK if I use Terminal and the 'cp' command (it works for all 3 machines)

7. I have NO problems with large files and Finder if I use a powered external with 3.5" drives via USB or Firewire (HFS+ or NTFS) on any of the Macs.

As you see, I think I've been pretty thorough. It seems as though Finder must be at fault when used with a bus powered USB external.

I should also mention that all 3 of my Macs are on Leopard 10.5.3, though I did also boot a my Intel Mac Mini into Tiger with the same result (Finder failed, 'cp' worked).

I have reported the problem to Apple, but wondered if anyone else has had a similar issue...and hey, a solution would be a great bonus!

MacBook Pro :: Errors When Copying Files To External HDs?

Jun 22, 2014

I have two WD Elements external HDs. I use a Belkin powered 2-port USB hub to connect them to my Airport Extreme (used as a server). I started out with one of them, a 1.5 TB, and purchased the second one when the first started to get really full. I use them exclusively for storing music files. My plan was to move files from the  nearly full drive to the new one. I began moving files, folder by folder (a painstaking and time-consuming process) from the one drive to the other. 

The first problem that popped up was this: in the process of copying a folder to the new drive, an error message appeared saying that the "operation could not be completed because you do not have access to some of the items." I in fact have full custom access to both drives, and am the only one who uses them. Another message I would sometimes get would be, "[file name] could not be moved because its name contains too many characters." 

I found this annoying but bearable until it started happening more frequently. What's more, when a folder failed to copy completely, that would leave me with an identically named but incomplete folder in the second location. An attempt to delete it would be met by another error message, "[folder name] could not be deleted because [folder or file name] is in use.

OS X :: External Drive Stopped Copying Files - Cannot Cancel Process

Aug 5, 2009

I am backing stuff up to an external drive (G-Raid 1TB, if that matters), and the process will randomly stop and not allow me to cancel out the copy process once it does so. I have had multiple problems with many drives (lacie and g-raid) in the past before, on different machines (G5 tower, mac pros, intel imacs, etc) so for some reason in my head I figure it as random. I'm guessing there's a hiccup somewhere.

They're all formatted correctly to handle large files, and I know it's not good, but if it hangs up and I pull power or shut down, it'll unfreeze and remount (about 80% of the time success rate, 20% of the time it wont even show up, not even in disk utility). This also occurs when I am going from external drive to external drive and internal drive to external drive. It seems very random. And finder seems to stall out too (like it is now) and when I try to relaunch it, it will not come back until one of the drives that is causing the problem is disconnected from the computer.

MacBook Pro :: Copying Users Files To External Disc - Some Data Can’t Bet Read Or Written

Jun 20, 2014

My Macbook pro wouldn't turn on. I booted to the installation DVD and installed OS X to the external drive. Once the installation was done, I was able to access my laptop without any problem and I retrieved all my files from the USERS Folder. I tried to copy my old files to the external disk, before formatting the system’s internal drive and reinstalling OS X.

However, at every attempt, I’d get “some data can’t bet read or written (Error Code -36)”. I ran a Verify/Repair Disk Permissions and this is what I got:

Software :: Files Disappearing After Copying / Newly Copied Files Missing From New Location

Dec 25, 2010

This only happens when she copies files between internal hard drives. After copying the files, she verifies that files exist in both locations. She then deletes the files in the old location. Then, newly copied files are missing from the new location.

I've never heard of this happening before, except for with improperly unmounted external drives. I have run disk utility and verified that there are no problems with either drive.

IMac :: Stop Downloading Files/copying To Clipboard And Saving Files To Desktop?

Nov 29, 2009

Why does my mac stop downloading files, copying to clipboard, saving files to desktop, etc?

iMac g5 1.9 ghz 17" running 10.5.8. Had a hard drive crash and bought a new one. Loaded new OS leapord. Everything works fine at first, but after the computer has been on for a while, it will stop downlading files, disk verify doesn't work. I can't copy and paste stuff. It seems as if the hard drive is full, but I have only used 32GB of 300GB.

When I restart, it works again, then slowly not. Is it an overheating issue? How do I know if my fan is running? Is it a bad hard drive I put in it? Bought it new with three year waranty.

Software :: Files Disappearing While Copying / Newly Copied Files Missing From New Location

Jul 2, 2009

On several separate occasions, one of our users has had trouble with files "disappearing."

This only happens when she copies files between internal hard drives. After copying the files, she verifies that files exist in both locations. She then deletes the files in the old location. Then, newly copied files are missing from the new location.

I've never heard of this happening before, except for with improperly unmounted external drives. I have run disk utility and verified that there are no problems with either drive.

Could anyone help explain why this is happening or how to prevent it?

OS X :: Copying Files From Windows To Mac?

May 6, 2009

I am in the process of buying a new MacBook Pro. It will be my first Mac, though I use one everyday at work (typing from a new iMac now).

My question is, when I get the MacBook, how can I copy all my files from my current Windows-based external HDD, onto the MacBook?

I am mostly concerned in saving my pictures and songs if it makes a difference.

OS X :: Copying Files Without Redundancy?

Jun 4, 2010

When backing up files to an external drive, I end up overwriting the older versions of files that were previously backed up. Is there a way to copy files from one place to another, but just have files that have been changed to update?

Kind of like how Time Machine or Drop Box works. It just senses changed files and overwrites those, but doesn't recopy unchanged files.

Software :: Copying Files From X86 To Ppc?

Jan 15, 2009

I am trying to move some files from an x86 machine to a ppc machine. Both are running Mac OS X 10.4 The files have some extended attributes set for them.

Hence, I used the tar utlity to create an archive and then moved the archive.

However, the file data is moved correctly but all the extended attributes are lost Why is this?

I learnt that all extended attributes are stored in the resource fork.

Both the machines have the HFS+ filesystem.

Hence, even the resource forks must get copied right?

OS X :: How Not To Lose IPhoto 09 Settings When Copying To External HDD

May 2, 2009

I've been storing all my pictures in an external hard drive, from which I linked my pictures to iPhoto '09. Now I have a new hard drive and would like to transfer my pictures to it but don't know how to keep all the information associated with the pictures in iPhoto (such as the "Places" and "Faces" info I've added).

I've copied all the pictures to the new HD, then opened iPhoto while pressing "option". Then I selected the folder in my new HD to be used by iPhoto, but it didn't work.

What should I do with the file in my Pictures folders (a file named 'iPhoto library')? Do I copy that to the new HD as well?

OS X :: Copying Files Over The Network To A Windows PC?

Dec 15, 2010

I have 13 files totalling about 4.5GB on my new MBP that I've tried to copy over the network to my Windows PC. The actual copy process itself indicates that all 4.5GB of data has been copied across, but on the Windows PC only 6 of the 13 files actually appear, so somewhere in the process the other 7 files have been 'lost'. Has anyone got any idea what could be going on here and how and where the other files have vanished to even though the MBP indicates the data has been copied over?

OS X :: Mac Extremely Slow At Copying Files

May 28, 2009

I just did a clean install of the mac and I'm noticing it is extremely slow at copying files back from an External HDD. It is on USB 2.0 connection, and still going maybe 10MB/minute. This is the speed I'd expect from a 1.0 connection. I've checked the wires, everything is connected. I thought maybe I'd speed it up by using an External DVD drive to copy the 20GB music library back from the DVDs rather than the external -- but the external DVD drive showed the same slow speed. The drive didn't even seem to spin up to read faster (like it normally would, it reads/writes quicker than the slot drive on the imac).

It just ran as slow as possible, with the same slow transfer rate. I've been going for a couple hours or more now, and only have 4GB of 16 copied over. I'm guessing there could be a reason for this that I'm missing. It's a fresh install, all updates installed on this Tiger 10.4.11 OS X. External is formatted HFS+ and the iTunes library does not contain any single file over 4 GB, or even close to 1GB. (just music/library files). There has been no problem with the media before.

IMac :: Copying Files From DVD Cause Restart

Sep 23, 2009

I'm having a problem with my Mid 2007 iMac. Some files copying from a DVD (Logic Express 9 Demo Content), cause my iMac to restart. I know the files are fine as I can copy from another mac. I've had this problem twice before since I've had my mac (Oct 2007), but it was in reverse (trying to burn to a DVD). Everything else works fine copying to and from the drive. I want to ring Applecare, but I can imagine that they will say don't worry about it, since its only them files, and everything else can copy fine.

I've tried all the basic stuff:

OS X :: Copying Files From NTFS Hdd To MacBook Pro?

Jul 16, 2010

While coping a lot of files from the NTFS drive(to a MBP13" '09) it caused my computer to freeze up, and I had to force a shut down via the power button . Anyone else have problems like this copying a large quantity of files?

Is there a GB limit you can copy at one time, or maximum number of files? FYI, my MBP locked up while it was "preparing to copy." It was stuck on just over the 40,000th file (was the large number of files the problem?).

MacBook Pro :: Copying Large Files From Old To New One?

Jun 19, 2012

I am having another problem transferring some larger folders from my old MacBook to my new MacBook. I am trying to move some very large folders and individual files from my old Mac to my new Mac, both running the latest Lion. I have tried this with both USB Flash drives and with external hard drives. Whenever I drag and drop from Finder to either the flash drive or the hard drive, the copying begins, but always gets stuck with the pinwheel at almost exactly 4.17GB. At first I thought that the formatting of the flash drive might be the culprit, but it also happens on the external hard drive that is formatted for Apple Extended. 

A very "time and effort" intensive workaround is possible if I just copy fewer than 4 GB at a time, which is what I have been resorting to. But this won't allow me to transfer my Windows 7 Parallel virtual machine, since that one file is over 90GB. As additional information, it appears that Time Machine isn't bothered by this limitation, since I can backup and restore these huge files from a backup. Unfortunately, Migration Assistant doesnt seem to permit the granularity of restoring just one file. why the system hangs at 4.17GB of transfer? By the way, this happened with Snow Lion too. It didn't just start with Lion.

OS X V10.5 Leopard :: Files Disappeared While Copying?

Jul 6, 2012

I copied 219 files (JPEG photo files) to a flash drive from my hard disk.Only 135 of them copied and the rest of them disappeared - completely.  No trace.They are just gone.They do not show in any searches. I ran the MacKeeper File recovery program and they do not show up there either. It seems impossible that they could just disappear while being copied but that is what has happened.
