OS X :: Large Amounts Of Data Copying?

Oct 29, 2009

I have 1.9TB on one drive, 645GB on another; I want to copy all that data onto a separate 6TB drive....

What's the fastest way to do this? I have already begun w/ 2 cp -pR commands, running in different Terminal windows, but seem to be getting lower disk activity numbers in Activity Monitor than I was with a brief test of a Finder copy... is that possible?

Any suggestions? Also looking for a (relatively) efficient way to verify the copied data after the fact.

Apr 22, 2009

I was just wandering if there is any software that people use for copying large amounts of data, or whether you just drag and drop/copy and paste with Finder?

Windows On Mac :: Sync Large Amounts Of Data?

Nov 26, 2010

I use robocopy (command line copy utility built into windows) to sync ~150GB of data between multiple windows machines. I've never had any issues, it will run and check the data to make sure it is synchronized, if there are no changes it can check the 150GB in a few minutes.

Now I have a Mac 10.6 that will have a copy of the data on an HFS partition. I'm connecting to the Mac from a Windows 7 machine via file sharing in Mac to Windows. I have robocopied the data onto the Mac system. However when I re-run robocopy all the files show up as Older or Newer time stamp so it will have to recopy everything making it useless for synching just changes.

I've tried the /fft switch for use with fat32 and file systems that don't store the time as precisely as NTFS

I've tried the /dst switch to check and see if Daylight savings is messing it up.

Anyone else have this issue?

Can you suggest any utilities that you use to sync large amounts of data between mac and windows?

Applications :: Mail - Incoming Messages In Large Amounts?

Nov 23, 2009

I have a 13" MBP running 10.6.2 and for some reason I randomly get Mail bringing in like 3,400 messages and i have not been able to figure our why. I have the following Mail accounts:

1. Work - this is pop and I know it can not be this account causing it as I only leave 1 day on server so there is not that many in there
2. .Mac - (mobile me) however i only have 2,784 messages in it so the numbers dont match up
3. gmail - this account only has 26 messages since i only use it for GV and syncing an Android phone

It does this very quickly for supposedly bring in that many messages and when it finished nothing has changed and i notice nothing new in my Mail accounts?

Applications :: How To Delete Large Amounts Of Deleted Duplicate Mp3s

Oct 21, 2010

ive got a decent sized itunes library, 20,393 songs/125.5 gbs of music in the program, but over time as i have added files a lot of times id get duplicate files so i would delete those, and when i deleted them i didnt always press the move to trash button, and just for what ever reason would sometimes press the keep file button, so now at this point after doing this for a while i now have a music folder that is 168gbs of music, when i really only have 125 in itunes so is there any program or way to automatically delete those duplicates, because it would take a rediculous amount of time to go and find and delete each one individually obviuosly.

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 :: 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!

OS X :: Copying Large Files To USB Hard Disk?

Jul 2, 2009

I recently picked up a USB Hard Disk, I plan on copying large files to it (for example 20gb VMs), I am wondering whether or not finder can copy files as large as 20gb one at a time because the last time I tried to do this on a USB Stick, the file transfer would either freeze or would end up taking way too long to transfer and in the end I had to pull it out and having to reformat it. DOes anyone here know if such things will happen again copying these files?

OS X :: Copying Large Files To Network Drive

Nov 22, 2009

I've recently purchased a NAS drive and would now like to copy about 500 GB of files onto it. Obviously this is a slow process! Is there a way I can set up the copy so that if it gets interrupted I can resume the transfer? At the moment the I just know X of 100 GB has been transferred. On the destination drive you can't see any of the files being transferred across until the entire operation is complete (on a pc you can normally see the files that have been transferred immediately) ... I'm a bit worried that if I turn my laptop off or I have any network issues the transfer will fail..

Hardware :: Speed Test For Latest Time Capsule / Copying Large File Of Over Giga

May 18, 2010

I'm wondering if someone with the latest Time Capsule (announced last week) can post the results of copying a large file (such as your iPhoto library or equivalent - ideally over 500MB) from the HD on your Mac to the HD on the TC over GigE.

Please report the time in seconds for the copy to complete and the size of the file. I'd like to understand if they changed the QoS on transfers to the TC HD.

OS X :: Copying Nearly 400 GB Worth Of Data From One Mac To Another?

Dec 4, 2009

I can rule out the home network for this job - way too slow, even at wireless-G speeds. Therefore, I'm going to be using an external Firewire 400 HDD to do the copy. I've already copied the data on the source Mac to the drive. How long will I have to wait for the copy job to complete (ignoring time spent setting up the drive and getting its cables moved/connected)? The destination Mac runs Snow Leopard, and supports Firewire 400. The source Mac runs Tiger, and is PowerPC-based (it's a Rev C iMac G5, with its memory upgraded to 2.5 GB and HDD upgraded to 320 GB), if that makes any difference - it's limited to FireWire 400 only, and lacks a FW 800 port.

MacBook Pro :: Ate Data When Copying Folder?

Jul 2, 2010

I'm a new mac user coming from Windows. I was copying a folder called Projects from my external drive to my MBP over the existing Projects folder thinking contents will be added to the existing content. However it seems that the old contents were deleted and new ones added. Is this how Mac OS operates? Is there a possibility to recover all this lost data? It's really annoying and it seems like a bug.

OS X V10.7 Lion :: How To Move Data Without Copying It

May 24, 2012

A few days ago, the Apple Store gave me a free "upgrade" on my MacBook Pro, from 10.6.8 to 10.7.3.However, Apple's gift has turned into a nightmare for me.I'm far too busy with work deadlines to have time for the 10.7.3 learning curve at the moment.Instead, I just want to go back to the pleasingly predictable 10.6.8.Therefore, I'm going to back up all my data onto an external hard drive, then completely erase the internal hard drive, and just start again, with a clean install of 10.6.8.

However, in order to do that, I first need to retrieve a 200 GB folder from the Trash.The folder which is in the Trash has NOT been deleted.Instead, it's just sitting in the Trash, waiting to be deleted.However, when I attempt to drag the 200 GB folder out of the Trash, and put it back on the Desktop, 10.7.3 starts copying the entire folder, instead of what 10.6.8 would have done, which would have simply moved the folder onto the Desktop without copying it.

In plain English, all I want to do is MOVE a 200 GB folder out of the Trash, onto the desktop, without copying the folder.Simple in 10.6.8.An apparent impossibility in 10.7.3.I've tried holding the Command key down while dragging the folder out of the Trash, but that doesn't work.Any workaround, which would apply to the entire hard drive, plus all external hard drives, even if it has to be a Command Line which I type into Terminal, that would be brilliant.

OS X Technologies :: Time Machine Just 'stops' Copying Data

Jun 12, 2012

I have Time Machine set up to backup my laptop, and it works just fine. I then decided, having enough space to spare, to point Time Machine of my girlfriend's laptop to the same backup location (she had been backing up to an external drive).

After setting everything up (network location, password, and everything), Time Machine happily starts backing up: Until it just stops copying/transferring data. 

I start with a fresh, new, clean backup and I get no error message of any kind; after Time Machine selected the files to back up (= first run, so everything gets selected; that's about 40gb) it starts copying everything. But then it just stops. No errors, no progress, no anything.

This usually happens after having copied between 1 and 3 gb (I tried multiple times). Being on a gigabit ethernet, the copying is pretty fast; the first gb takes minutes. I even proceeded to letting the laptop run its backup through the night; even after a dozen hours, the indicator still is stuck at "1.27 gb of 40.24 gb" (or whatever). 

I went so far as to check the laptop's hard drive (no errors). The backup system appears to work just fine; after all, Time Machine starts the backup just fine and doesn't report any errors or issues. (Also, if there was something wrong with it, it shouldn't work with my own laptop, either.) The only difference I could think of is that my laptop runs Lion, while my girlfriend's still runs Snow Leopard (both to their respective newest versions; could this discrepancy be the cause of any incompatibilities?).

Power Mac G5 :: Copying Data From Dual 2.0 G5 To Formac Raven 1TB Ext FW400/800 HD?

Nov 9, 2007

1. I've just purchased the Formac Raven 1TB Drive (Firewire 400&800)
(Formatted into 2 Partitions Mac OS Extended Jour)2. I'm trying to copy large amounts of data (100-200GB) from either my 2 internal drives on my Dual 2.0Ghz G5 (OS 10.4.10) or from the USB 2.0 Freecom 500GB Drive to the Raven 1TB Drive.

3. After 4-20GB of data has been copied the copy window just sits there and won't go any further! I have to turn the Raven off and then back on again to stop it!

4. I have tried both FW400 and FW800 ports on my G5, but still the same problem.

5. I have verified all drives and repaired any errors and fixed permissions.

6. The Raven have been low level formatted, and split into 2 partitions.

7. I have a MacBook Pro Core 2 Duo (OS 10.4.10) , and have copied 200GB from it to the Raven without any probs!

8. Any ideas why the G5 won't allow me to copy large amounts of data?
Single file copying is fine! eg. Disk images of 4-7GB

Hardware :: Time Capsule To "Beep" Copying Data

Oct 19, 2009

I just bought a new Time Capsule 2To from an Apple Reseller in my town. I'm running Windows Vista here & copying some 17GB files on it. While it's transferring, i hear some beep, but it's not cyclic, it's like 2 beep then nothing & 1 minute after, 3 beep, then 2 beep and nothing for 2 minutes or 2 beep & 4 beep & 2 beep. So here is my question : I bought this Time Capsule to have more HDD backup & save documents on it. is that a sign of defectual disk? Second question : how can i backup the Time Capsule ? If i go 500Go on it... ? I just don't want to change it, if i get the same bip with all TC when i transfer files on it.

Windows On Mac :: XP And OS X Report Different Amounts Of RAM?

I was running the Windows 7 upgrade advisor and it gave me a result for RAM that I wasn't expecting. My MacBook Pro has 4 GB of RAM. At least that's what I ordered, and that's what OS X says.

When I look at the RAM on Windows XP under VMWare Fusion, it tells me I have 512 MB of RAM.

Where I look at the RAM on Windows XP under BootCamp, it says I have 2.73ish GB of RAM (which doesn't even make sense).
