Cannot copy files to/from external drive

Hi All,
Bit of a cry for help. I run an iMac 3.06 Ghz Intel Core 2 Duo with 10.7.3 and I'm having some serious problems with an external drive. Some history first - I have a large iTunes library (~3Tb) of everytype of media which I stored on an external NAS (iomega StorCenter) with no problems - then this NAS started to report a drive error with imminent failure. I purchased a new DAS (Western Digital) drive and moved all my content from the NAS to the DAS and everything was ok. Then I started to get errors through iTunes about cannot find the file and cannot read the files - and then I couldn't access anything on the drive. At this time I thought this was a different problem because I was running preview Mountain Lion, or there was an actual fault with the disk. After investigation, and coughing out for Data Rescue 3 I found that somehow the entire file structure had been corrupted and all my files had been orphaned. So at this point I had one dying NAS drive and one DAS which wasn't usable and no space to recover any files to.
So - next step was to purchase another external drive (and returned the WD) - this time I went for a G-Raid 4Tb (non-thunderbolt) drive and I've been in the process of recovering files from backups and iTunes. I've had no problems until today when yet again I've started getting errors and now I have problems copying files to/from this G-Raid drive.
Technical details - OS-X 10.7.3 - G-Raid 4Tb formatted as Mac OS Extended (Journaled) - currently showing 1,163 folders and 15,452 files.
Symptoms - using finder drag and drop copy a file from the g-Raid to desktop results in 'The operation can't be completed because the item 'xxx' is in use. - 'The operation can't be completed because one or more required items can't be found (error code -43).' and the copy fails.
Using the cp command I get a 'Resource Busy' error.
However, this is not for all files - I've managed to copy all my books back to the desktop ok, when a couple came up with the above error I tried again and it copied successfully.
I have run Disk Utility - here are the details :-

and it's just got worse - in getting the info for this post I no longer have access to the drive.
This is the second time this has now happened on two different directly connected drives (USB and Firewire) - which means the problem is elswhere. I've a stack of errors in the system.log file

I'm now out of ideas and when I got in touch with G-Tech support I got "Unfortunately the drive seems to have been corrupted. You can try to retrieve the data using third party data recovery software such as Data Rescue 3. You can find the software at a discounted rate at the following page:http://www.thedatarescuecenter.com/gtech-data-recovery-software.html If you have any further questions, please feel free to ask."
any help/advice/pointers very much appreciated as I really don't want to have to start recovering again :-(
Thanks all.

Hi Ncat,
I might have had similar problems with yours. Finder stuck at 'Not Responding' while I boot my Macbook Pro with external HDD plugged in, my macbook heats up considerably maybe because it keeps trying to access the external disk. And Finder can only proceed after I unplugged my external hard disk.
So what I did was:
I rebooted my macbook into recovery mode (by holding cmd+R before / during the booting chime
I used the Disk Utility from there (instead of from normal booting)
Then I proceed to with 'Repair Permissions' and 'Repair Disk' for each and every partition of the external harddisk, and also my internal hard disk.
Rebooted after everything's done, and now it seems to work.
I hope that it will work for you

Copying Files To/From External Drive: Error -36

I recently purchased a WD 700 GB drive that I'm using as a network drive using AirportExtreme. Today, while trying to copy files from either of my internal drives to the WD drive, I get error -36 messages. If I'm copying a folder of files and click on the option "skip" after receiving an error message for a particular file then the entire copy transaction aborts. I have taken the following steps:
1) Disconnected WD from netywork and connected it directly to my G5.
2) Ran Disk Utilities and got 1 error on 1 of the 3 partitions which was repaired.
3) Re-ran Disk Utilities and got no error.
Tried moving folders of files and groups of files from WD to G5 and received same error -36 message.
Tried moving folders of files and groups of files from G5 to WD and received same error -36 message. Cannot move even a single file - of ANY size - w/o getting error -36 message.
4) Checked permissions and "ignore ownership" settings on volumes concerned then logged in under root.
Same problem continues. Tried moving files between my internal drives - no problem. Now here's the thing: the only files I have moved to the WD drive thus far are my music files. The iTunes Library on my G5 is pointed at an iTunes folder with these files inside. Last 2 weeks or so there's been no problem.
I NEED TO GET THESE MUSIC FILES OFF or COPIED or BURNED to another disk. In that vein I tried:
5) Unsuccessfully creating an image file of the files on the WD but always ended up with a much too small and empty .dmg file.
6) Burning files to DVD - same error -36 messages.
7) Repaired permissions on my G5 - just 'cause. No help.
8) Re-ran Disk Utilities on WD: repairs not needed.
9) Re-booted; error -36 messages continue to pop up.
I'm at a loss as to what to do and am especially peeved because I bought the WD at the suggestion of a clerk at the Apple Store even after I pointed out to him that the WD was getting very mixed reviews on Apple's site. I'm not angry with the clerk but at myself for purchasing the WD even with my misgivings.
How can I copy to another disk the ONLY copy of my music files from the WD drive so I can either reformat or return it?

A couple of ideas:
1. Do you have an iSight camera or an iPod connected to another Firewire port? If so, unplug them so that the only Firewire device is the drive.
2. Unplug everything except the keyboard and mouse and download and reapply the 10.4.10 COMBO update. Make sure no other program is running when you apply the update, and do nothing whatsoever until the update finishes.
3. Have you tried plugging the drive into another computer to see if it works? If so, copy files off on the other computer and burn them from there.
4. Does your iTunes work and access the files? Have you tried creating CDs from iTunes?
If all else fails and you have a spare drive slot in the G5 that will take the type of drive in the enclosure, you could always try removing it from the enclosure and putting it into the G5 and see if it works there. The problem could be the innards of the drive enclosure rather than the drive itself.

Cannot copy files direct from PC to DROID-Mini

Have direct connection to PC (Win7x64 OS) via USB data/charge cable. I am trying to copy MP3 files to the Music folder on phone but I get "Device might not be able to play this type of file", and then "Cannot copy file." I assume this phone can play MP3 files. I was able to create a subfolder in "Music", but cannot write to it or the main "Music" folder. The main reason I upgraded to this phone was bluetooth connectivity to my Sena motorcycle bluetooth wireless headset/intercom/phone system - mostly to play music. From what I can tell from the less than detailed manual, I should be able to copy files to the phone storage from a Win7 PC. Any help appreciated.

Easiest way I find to transfer photos/music is to use mass storage mode.
Plug in the device, it asked for mass storage mode permission..
Then it pretty much works for ur memory card in the device as an external harddrive/usb.
Get access direct to move things freely between memory card and pc.
Go to options> Media Card> Change Mass storage mode support to ON and Auto enable mass storage mode to prompt..
If your issue is resolved, put a checkmark in the green box that contains the resolution.

If it was just/or also really helpful - Give it a Kudos.. Go on Mate.. Help the rest of the clueless blackberry user world find their answer too..

Deleted Files disappeared from external drive but space is still occupied ( iMac )

Hello all...
I have this problem.
Whenever I delete items from my external hard drive, using iMac (running mavericks), the files disappear from the drive window but their space will be still occupied. if i format the drive using my mac, everything will disappear & the whole drive capacity would be available for use.
Thanks in advance for your help.
Luk

Unless you empty the trash while the external is attached, the files will remain in the trash. You will gain back your space after you empty it.

Cannot figure out how to copy saved library from external drive to new pc

I had to reformat the PC that housed my iTunes collection. I backed up my iTunes library to an external drive according to the instructions posted here: http://support.apple.com/kb/HT1751
Now, I am unable to get the data back on to my reformatted PC with the playlists, etc., intact. What am I doing wrong? Thanks.

Press *and hold* the shift key while starting itunes. When prompted, choose to open an existing library.
Browse to the ITL file you backed up on the exHD.
The ITL database file is what holds all the metadata you're missing.

Help! Error 36 When I try and copy files to my external drive

Yesterday morning I discovered that I can't copy files from my desktop to my external hard-drive. The last time I performed this action was Saturday afternoon were all worked as normal, and to the best of my knowledge I've changed nothing on my system since then.
When I try to drag a file from the desktop to a folder on the external drive I get the message
The Finder can’t complete the operation because some data in “X” can’t be read or written. (Error code -36)
The external drive is the drive I use for my iTunes music files, and I've discovered this morning that I cannot import a CD to iTunes, however I can burn a playlist from iTunes to a CDr.
I'm using an iMac, and the external drive is a Western Digital 1TB (Journaled HFS+) connected via firewire.
I've seen references to similar issues through Google searches, but no definitive answer, can anyone help?

I/O error -36 bummers!
It could mean that there are bad blocks on the disk. Backup everything on that external disk now, if you don't already have it. Unmount and disconnect the external. A -36 error could also be just a poorly connected cable, or a bad cable or port. Remove all cables and reconnect making sure the connections are tight.

Copying to and from external drive causes Finder Freeze

I recently purchased a Shintaro USB HD dock to archive my many Gigs of Video footage.
I plug it all in and powered up without problems. Plugged a SATA disk into the dock it showed up (it was previously formated in an FW drive)
The drive showed up on the desktop and the files on it were there as well. When I try to either copy files to or from the dock the copy window comes up works for about 40% of whatever file I'm copying and then Freezes.
I've tried several disks and all do the same.
I cannot relaunch the finder, I cannot stop the process in Activity monitor, all I can do is power down, restart and try again.
I have tried using both a USB hub and hooked direct to the USB card in my PowerMac but the same thing happens everytime.
When I look at the external drive it has all the icons there but all the files are Zero Bytes.
Anybody got any ideas ?

Hi Brett,
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
Use Disk Utility to Repair the external drives.
While still in Safe Mode, move these files to the Desktop...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.

Can't copy files to PC external drive

A PC-using friend gave me an external drive with AVI files on them. I can copy the AVI files to my desktop from the external drive, but can not save or copy any AVI files to the drive. I can't change Permissions in Get Info to access the drive.
Any ideas 1. Why this is happening?, and 2. What to do?
Thanks

Sounds like the drive is formatted as NTFS. If so, you'll only have read-only access to that drive.
If you need to write to the drive, it will have to be reformatted as FAT.

Unable to copy iphoto library from external drive to internal drive

iPhoto '09 8.1.2 (424)
I have a very large iPhoto library (282GB, 34k photos) spread between multiple computers, which as been consolidated on a single external drive now (1 TB Western Digital Mac OS Extended (Case-senstive, Journaled). I'm trying to get the big library on the external drive back on my Mac Pro so I can break the merged libraries into smaller libraries in a safe fashion.
There is nothing on the internal drive, but I keep getting an error about 62GB into the copying that reads: "You cannot copy "[Library Name]" to the destination because its name is the same as the name of an item on the destination, except for the case of some characters." ... But there's nothing on the internal drive!!!
I've renamed the library on the external drive, then tried copying it -- no dice. I've created a new folder on the internal drive and tried copying it to the new folder -- same error at exactly the same spot in the transfer. I've even reformatted then zeroed out the internal drive -- same error, same spot. Anyone know a solution or have ideas about what I'm doing wrong?
Many thanks!

I think the error report is bogus and the issue is not on the receiving volume but a locked or damaged file within the library.
Try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair Library permissions.
FWIW, I don't see what you gain by a: splitting the library at all and b: copying it back to the MacPro to do it.

Problem copying files between two external drives...

Hello, and thanks for any ideas on this one.
I have a punch of .m4v video files on a 1TB Lacie external drive, but re cently bought two 3TB Seagate drives and wanted to move all these media files over to one of the new drives. Most of the .m4v files moved just fine, but I encountered two different issues in the process that I can't resolve.
I'm on an Intel-based iMac (Core 2 Duo), running OSX 10.5.8.
1. Most pressing problem:
One of the video files, when I try to copy, causes the finder windows to completely freeze requiring a hard reboot of the machine to fix. I can get infomation on the file OK, and can play it off the original drive just fine, but try and copy it and all manners of computer death take place. There does not seem to be a permissions issue, and the file isn't flagged as locked.
This command produces no fruit either: $ lsof | grep videofile.m4v
2. Second issue:
This one affects two other files. When trying to move them over, they get approx half way there and then I get a notice that the operation cannot be completed because the files are supposedly in use.
All the googling I can do on that error seems to bring up cases where files can't even start to be moved... but in these two files, they get half there. Or maybe they're read OK but then can't write? Either way the status bars show about 1 GIG or 1.7 copied. I don't know.
I also checked the permissions, the locked setting, used the lsof command, etc... no luck.
About 100 other videos copied over just fine.
Any ideas are greatly appreciated.

Thanks for the response... I tried just now, no luck.
I did at least get an error this time for problem one above before the lock up... lol... error code 36. So far searching for that isn't coming up with any solutions either.

Files missing from external drive

I have a 4 TB G-Tech RAID drive attached via FireWire 800. It was formerly a backup drive for photos/videos, moved up to a main drive when the old drive it was backing up failed. Problems got in the way of replacing it....
Anyway, all of a sudden, my files were gone. Just gone. For some reason, the folder hierarchy is still there--every folder, as best I can tell is where it was, but any and all data is gone.
Disk Utility found nothing wrong with the drive; DiskWarrior didn't, either. I booted from another external drive running 10.6.x, no change in what wa(sn't) there, and ran TechTool Pro 5 (I'm running 10.8.3 and don't have a newer version so it ran off the older OS); no help.
I ran Data Rescue for a few days and it seems to have recovered a lot of files--but we're talking almost 3 TB of data, and I shudder at how many months it's going to take me to get it back into a semblence of order, as well as how much I've actually recovered.
The part that makes me hit my forehead is that I ran the Deleted Files function, which scans free space only. I did so because, at the time I ran Data Rescue, there still was data on the drive, about 600 GB of photos/videos. But when it had finished, all THAT was gone, too, and I wonder if I should have done a Deep Scan and missed files as a result.
But here's the thing: If I do a Get Info on the drive, it says that the capacity is 4TB. But, if I open a Finder window and show the top level (with all of the volumes shown) and use List view, it shows the drive as being 2.99 TB in size. So... is that data is still there, somehow? I.e., is there anything recoverable in a *useful* form--in the original folders and with the original names, rather than hundreds of thousands of undifferentiated files that DR presumebly found?
Side note, and perhaps a red herring. The drive had been running slowly for a while, though tests didn't show why; see here. The drive had seemed to recover itself, but then got slow again. I downloaded Drive Genius (demo) and tried to run the Benchmark function, only to find that it didn't run in eval mode. At some point, I found that my iMac was running slowly, and I opened Activity Monitor and found an odd process taking up a lot of CPU: dgse. Couldn't figure out what it was, and Googling didn't reveal anything. So, just in case I had a Trojan, I quit it. It was right after this that I found my data gone. I later tracked the process to Library>Application Support>Drive Genius
Sure seems darned coincidental....

Thanks. Ran it twice, but it didn't restore the files. Still, it gave me the following:
The original directory is damaged and it was necessary to scavenge the directory to find file and folder data.!
Some files that had been lost or thrown away may have been recovered.
Comparison of the original and replacement directories indicates that there will be no changes to the number or contents of files and folders. All files and folders were compared and a total of 807,104 comparison tests were performed.
• All errors in the directory structure such as tree depth, header node, map nodes, node size, node counts, node links, indexes and more have been repaired.
• Volume Information had to be scavenged from the file system journal.

HP dv6-6188ca windows 7 pro 64b amd chipset 8G locks up copying files to/from external usb drive

When ever I try to copy a large (>2G) file to or from a external usb drive the computer starts the copy but gets stuck. It has to be powered off and the battery removed to get it to work again.

Please repost your inquiry in the Microsoft Windows 7 Performance Forum.

Can't copy Iphoto library from external drive to hard drive

I have a 210 gig iphoto library that I am trying to copy from an external hard drive with 440 gig of avaliable space. I am getting a message say it can't copy because there is not enough space. The math doesn't add up

Try the following:
1 - run Disk Utility and repair disk permissions.
2 - launch iPhoto with the Command+Option keys held down and rebuild the library.
3 - Run Option #4, Rebuild Database, followed by Option #1.
4 - try dragging the library to your internal drive again.

Cannot copy file (From external HD, DVD, server) - iTunes 6

Yesterday I've updated iTune to 6 and de facto Quicktime to 7.0.3.
Just after this upgrade, I remark that I cannot copy files, using the finder, from external hard disk, dvd drive and network drive. During the drag, I've got the circle indicating that I can't copy.
I can copy files only from my main hard disk to this one or others.
(Note: With terminal applications I can copy theses files).
Anyone else have this problems... or a explanation/solution.
Thanks

I reinstall iTune 6 and now everything is ok

Welcome to Apple Support Communities
When you try to copy data to the external drive, what happens? If you don't see any error, the external drive is formatted in NTFS, and OS X can't write in it.
To be able to write on this external drive, you have to use an app like Paragon NTFS. Another solution would be to format the external drive in FAT32 or exFAT with Disk Utility > http://pondini.org/OSX/DU1.html Make sure you copied all the files of the external disk to the internal disk before doing it
