Mac writes files as compressed to ntfs external drive

I bought an external hard drive and formatted it to ntfs.  Whenever I copy files from the Mac to the external ntfs drive it automatically converts it to a compressed ntfs file.  This is very frustrating because my media player only plays uncompressed files, so I can't play my files on it.  Is there anyway to *prevent* my mac from automatically compressing the files when they are copied to a ntfs drive?

NTFS files can have a "compressed" attribute to them.  It saves space at the expense of processing power.  If I were in windows, I can check a box that makes the file compressed or not.  I don't think I was using a utility to do this, I read here (http://en.wikipedia.org/wiki/Ntfs#Mac_OS_X) that "Native NTFS write support has been discovered in Mac OS X 10.6 and later, but is not activated by default, although hacks do exist to enable the functionality".  If I've been able to copy to the drive doesn't that mean I'm writing to it?  In any case, the files I copied to my NTFS drive were all compressed.  I read somewhere else that if you copy a file from OS X to a compressed folder on NTFS, then it will automatically compress the file as it is copied into that folder.

  • HT1549 How do I read write to an external drive?  I am under admin account and cannot read write to any folder on the external drive.

    I have a Mac Mini with Mavericks installed, as well as a PC running Windows 7.  I want to be able to read write from both computers to an external drive on the Mac.  I created 2 folders on the drive and named them Movies, and TV Shows.  The content of those folders are the respective files. I set up both folders to be shared on the Mac under system preferences, and then mapped the drives on the PC.  I also created a user account with admin privileges on the mac that matched my PC.   I then copied a Music folder to the root drive instead of using external, and set up sharing as well.  File Sharing is selected for all three folders, however the music folder is the only one which allows me to change the permissions to allow read write to everyone, or to create individual user accounts to connect with read write permissions.  The options to add users or change permissions are simply grayed out for the two folders on the external drive, so not only can I not write from my PC, but I can’t even do it on the Mac with the administrative user logged in. The folder on the root drive is fine but I cannot make any changes to the external drive at all.  Get info for any folder on drive shows read only.  SMB and AFP are selected for all folders under options.  I can access all three folders from PC, but can only add files to the Music folder. I cannot do anything from either computer to the folders on the external drive.

    Try Applications/Utilities/Disk Utility - select the drive and run Repair Disk.

  • Itunes is copying/converting 500gb of music from .wma to .m4a files that are on an external drive onto my laptop which doesnt have enough room. how do i reroute these newly converted files somewhere with enough space for them?

    itunes is copying/converting 500gb of music from .wma to .m4a files that are on an external drive onto my laptop which doesnt have enough room. how do i reroute these newly converted files somewhere with enough space for them?
    new to itunes, used windows media player before that and always ripped music directly to an external hardrive and accessed it through the player. now that i downloaded itunes it is taking from the external hardrive and copying a second file for each song onto my lap top hard drive which does not have the capacity for all my music. as itunes converts music files i want them saved back onto my external drive or another location i have space for rather than the lap top. how do i change the setting to move the itunes media folder to another location. assuming that hitting copy and past and dropping it in a random location will cause a few errors.

    When I have done this, all I did was network the two machines and copy the contents of the iTunes folder to the other machine, and that's it.
    My understanding (which may not be 100% correct) is that the one file that is absolutely necessary is iTunes Library, and that the XML file is actually a copy auto-generated from the iTunes Library, appearing in a different format only for non-iTunes apps that take advantage of the iTunes Library data.
    As far as I know, if you simply have the Library (database) file and all your original music files, iTunes on that computer should operate as it did on your old computer. I believe that the Album Artwork, Genius Data, and XML files can be regenerated from the Library file. Not sure about the Extras file.

  • Deleting files permanently through LightRoom on external drive

    My LR files are stored on an external drive and the drive is called Buffalo NAS and it has a "trashbox" for deleted files.  My IT says I should clean out the trashbox using LR and I can not figure out how to do this.  I do not want deleted files eating up hard drive space on the external.  This forum as been great for answering my other questions and I thank all in advance who might help with this.
    JWT

    Hi JWT
    LR only manages the folders you have selected for import and development (editing).
    If you want to use LR to delete “managed” folders it’s possible to select them in the Library (Folders tab) and then remove and optionally delete from your hard drive or NAS.

  • I'm attempting to transfer files, address book, etc from an external hard drive to my new Mac-mini using migration assistant.  The external drive is showing up on my desktop but Migration Assistant is not seeing the drive when searching for devices

    I'm attempting to migrate files, address book, maile, etc to my new Mac Mini using an external hard drive and Migration assistant.  I followed the instructions on using Migration Assistant to do this but Migration Assistant is not seeing the external drive, which is displayed on my desktop

    I've been chasing this problem all afternoon. I had to reformat my internal drive on my MBP and reinstall Mountain Lion   Start up assistant wouldn't see my extrnal drive with the Time Machine files on it.  After many tries, I skipped the restore there and let the system boot.  I could see my external drive from Finder and the files looked OK.  I was told to use Migration Assistant and it had the same problem.
    I saw a hint on one of these posts that the icon that you see and is label Macintosh HD is actually your backup disk and it is telling you that it has a copy of your internal Macintosh HD.  I went ahead and told it to continue and it started to restore my apps, settings, and documents.  It's been going for a couple of hours, and is close to being done.  I expect to see my old system restored when it is finished.
    Wish that Apple would put some type of note that it is seeing the backup. That is most confusing and seems to be a problem for lots of users.
    It's been a month or so since your post  Did your get it to work?

  • Mac Formatted Time Capsule w/ PC Formatted External Drive Via USB?

    I use a Mac-formatted Time Capsule to run Time Machine backups on my MacBook Pro.  My wife backs up her PC laptop on a PC-formatted Western Digital "My Book" hard drive which is powered via A/C wall adapter.  I connected the Western Digital PC drive to the Time Capsule via USB so it would be available on our home network and my wife could run her PC backups wirelessly, BUT the drive is not showing up on our network.  Anybody have any idea what I'm doing wrong?

    Thanks for the in depth clarification.  A few follow up questions:
    1) Are you saying that even though I am only using the TC (in this instance) to make the windows drive available on the network, the drive still needs to be formatted in HFS+?
    HFS+ or FAT32.. the later having severe issues with large disk and large files.
    Great.  I'll do HFS+
    2) If I format the windows drive in HFS+, will the windows laptop be immediately able to write/read to it over the network?  Or will I have to install some sort of program on the windows laptop that allows windows to read/write to HFS+ (which I've always undewrstood to be a mac only format)?
    The format of the disk connected to a NAS is totally irrelevant.. if it offers windows networking file protocol.. ie SMB then it can store files on the hard disk.. it is just like sharing the disk in the Mac.. you can write to that directly from the PC. Try it.. The disk is controlled by the Mac. But it presents SMB to the Network.. On your Mac, go to system preferences.. sharing.. it should be in Internet and wireless.. but on Lion I have no idea. Open file sharing which should be ticked..there should be a public folder by default.. you can add others.. go to options, turn on SMB.. then from the windows computer you should see the disk available in networking. If not fix the names to SMB standard.. you will need to do this on the TC as well.. short, no spaces.. pure alphanumeric names. Copy some files from windows to your Mac.. you have now copied to a network drive.. with the drive format totally irrelevant to your windows computer.
    I'm sorry, but I don't know what "windows networking file protocol" and "SMB" mean.  Also, when you say "NAS" are you referring to the Time Capsule or another device?  Can you please explain things like "The disk is controlled by the Mac but it presents SMB to the network" in a less advanced way.  Pretend I'm a child.  You won't be far off.  It seems like this technique you're explaining is a way for the windows PC to write to the external drive via my MacBook.  Is that even close to correct?  The setup I must create needs to work regardless if macbook is on/off/out of the house.
    3) Does plugging a USB drive into the TC never work properly or is this just a semi-common problem that happens sometimes?  My odds of success will probably dictate whether I try this or not.  I already own the windows USB drive and would like to avoid buying more hardware if possible.
    It is problematic enough that I recommend you try it before committing to it. Even if you have to copy the files off to another location and then reformat the drive. Test it for a couple of days.. the issue happens especially when you are using Lion.. but will also happen with windows. Especially when the disk spins down it will not spin up again and become available to the network.
    Got it.
    4) What do you mean by files being in "native format"?  And what does a dead TC have to do with whether or not they can be recovered to the windows laptop?  If the TC dies, can't I just plug the windows USB drive directly into the windows laptop and it will be the same thing as connecting the drive and laptop via network?  How does a dead TC make things more difficult?
    Thanks for your continued help.
    HFS+ is not windows native format... so files stored by the TC on the USB drive.. when the TC dies.. they all die eventually may be difficult to recover unless you plug it into another TC.. as the PC cannot natively read them. If you format FAT32 then the windows computer can read it.. just there are other issues. eg the disk can be slow.. very slow and it has far less protection. eg a power failure can corrupt the drive.. this was an issue before we moved in windows to NTFS.
    Why do you say "files stored BY THE TC on the USB drive"  Why is the TC storing files on the USB drive?  Isn't plugging the USB into the TC just making the USB available on the network to my windows laptop?  Why is the TC storing files?

  • Opied files got corrupted in USB3 external drives connected to Macbook Pro, how to fix it?

    I use USB3 connected external hard drives in my Macbook Pro mid 2012 (Yosemite 10.10.1) frequently. I had no problem until two months ago. This week I noticed a lot of corrupted files in one ext drive connected to USB3 port. Luckily  I have a backup, and I copied back the files. But the files copied recently were also corrupted even though source files are fine. I spent a whole day trying to fix it using different methods of copy and options, e.g. erasing the drive, using cp, rsync, ditto and a combination of their options. I figured out that if I use cp or cp - R for copying single file or folder, it works fine, but using of rsync, ditto or recursive cp or finder's drag and drop result into a lot of corrupted files in the target drive.  This is not the problem of external drive.  I was surprised to notice that all files are copied perfectly when I used a old macbook (2008 model, it only has USB2 port, and OSX Mavericks). Since I have almost 2TB data to write, USB2 is very slow. I want to use USB3 of Macbook Pro 2012, but I am very disappointed to find out that USB3 in Yosemite is causing the trouble, writing out corrupted files. If anyone has a solution to this problem, or a second thought, Please suggest.

    Disk is formatted to Paragon NTFS

    My guess here is there is some issue with the use of Paragon NTFS. Perhaps updating it or using another NTFS driver (like Tuxera, or its free alternative NTFS-3G) will work. All in all, using NTFS in write mode with these options will be using a non-supported approach for accessing your drive, which could lead to odd problems if Apple makes a change that interferes with the functions of these drivers. At other times, such drivers use inherently less stable approaches (such as the FUSE environment) that could lead to problems if not formatted correctly.
    If your drive is working, and the formatting is checked out properly in Windows and other systems, then I'd suggest you check on your NTFS driver and update or replace it. Alternatively, if you only use the drive with your Mac, then consider formatting it to Apple's native Mac OS Extended. Lastly, if you use the drive with multiple operating systems, then consider using FAT32 or ExFAT as the format, as these are fully supported in OS X (unlike NTFS, which is only supported for reading).

  • Yosemite - Spotlight NTFS external drive indexing issue

    Good morning!
    Yosemite's spotlight doesn't seem to find any of the files on my external NTFS hard drive. I would like to know whether there is  a way or not to get it done.
    PS: I've added it to the privacy tab, removed it and it still not indexing. Also used the  "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist" code in terminal.

    By default, OS X ships with NTFS read capability. OS X would need a third-party (Tuxera, Paragon) NTFS driver package that enables NTFS write functionality in order for Spotlight to index the NTFS drive.

  • AirPort Extreme and USB NTFS External Drive and Canon MP810 printer

    The AirPort Extreme works great as a wireless router. And with the additional AirPort Express, I now have a WDS in my house. I can also stream my iTunes downstairs. This is all great, it's working.
    What's not working is:
    1. Adding a USB NTFS-formatted external Maxtor drive to the USB port Extreme.
    2. Able to copy, scan, and use "all" printing functionality of the Canon MP810 USB printer when connected to the USB port of the Extreme. Please I note I can choose File, Print from most applications and it works, but I can't use Canon's My Printer tool to access the printer wirelessly.
    I guess I'd like an unofficial confirmation that this is correct. I am a little disappointed that Apple didn't communicate this correctly in any of their specifications.
    I will begin looking into the comparable Linksys wireless router, but I have the strange feeling that I will get the same results.
    I don't know how Dell is able to do it with it's AIO 966 printer.
    Thanks,
    Frank

    1. Adding a USB NTFS-formatted external Maxtor drive to the USB port Extreme.
    Problem arises as OS X can not write to NTFS formatted drives and therefore you need to use HFS+ or FAT32.
    2. Able to copy, scan, and use "all" printing functionality of the Canon MP810 USB printer when connected to the USB port of the Extreme. Please I note I can choose File, Print from most applications and it works, but I can't use Canon's My Printer tool to access the printer wirelessly.
    Can I scan using my all-in-one when it is connected to the USB port of an Airport Express or Airport Extreme Base Station?

    I guess I'd like an unofficial confirmation that this is correct. I am a little disappointed that Apple didn't communicate this correctly in any of their specifications.
    As you can see from this page
    http://www.apple.com/airportextreme/specs.html
    It does state quite clearly
    +For shared printing with a USB printer +
    If it allowed scanning, I am sure it would have said
    +For shared printing and scanning with a USB all-in-one+
    or similar.
    If it doesn't explicitly say it will do something I would assume it can't.

  • Partition NTFS External Drive to work with Time Machine

    Hello Apple Support Community,
    I use a 1TB External NTFS hard drive to backup the contents of my Desktop Windows computer. I was wondering if I could use Disk Utility (or another tool) to partition the external hard drive so I could use TIme Machine on it. That way, not only would I have my desktop backed up, but also my laptop.
    I'd delegate around 700GB for my Windows Desktop and 300GB for my MacBook Pro.
    Is this possible? Or do I need to erase the entire external harddrive and backup everything all over again?
    Thanks,
    David

    Requirements to use Time Machine
    Time Machine is only available with Leopard or later.
    External FireWire or USB 2.0 drive
    Time Capsule
    Drive shared by a Mac running 10.5 or later using File Sharing
    Drive shared by a Mac running 10.5 Server
    SAN volume managed by Apple's Xsan file system
    A TM drive must be partitioned with either APM (PPC) or GUID (Intel) and formatted Mac OS Extended (Journaled.)
    Clearly you cannot use Time Machine with an NTFS formatted backup drive. Furthermore, Disk Utility cannot partition an NTFS formatted drive. In my opinion you should use separate drives for separate backups.

  • Paragon NTFS and copying to NTFS external drive-won't copy just makes alias

    Hi,
    So I got Paragon and it allows me to go into my boot camp and external hard drive and edit, copy, write to those drives.
    When I first set it up, I moved some folders and files over to my external drive. When I went back to those files later on, the folders were there, but all my video files were just an alias.
    If I have paragon turned on, I can open the files and it shows them as actual files (not an alias file type) and it plays perfectly. But if I have paragon turned off, it returns to just an alias and does not open.
    So, to test what was going on, I deleted the alias and recopied the file onto the external and deleted the original off the mac (and emptied trash). Still the same problem and result (there if paragon is turned on). I tried the same process but doing a move and still didn't work.
    But the other folders were able to be copied and accessed.
    So is there a limitation to file size (smallest file is only 125mb)? Or is it just video files? Or am I doing something wrong? I have yet to try the same process above with a non-video file.

    I suggest you ask this on the Paragon support forums. this is clearly a problem with Paragon not OS X itself.

  • Moving files from iMac to an external drive

    I have a 250 gb iMac and a 1 tB external drive (Seagate). My iMac is getting quite full, so I tried moving some files to my external. It told me that I couldn't because these files needed OS X to operate. How can I move files to my external so I can clear up my iMac drive?

    Greetings,
    Is the drive you are moving files to the drive you use for your Time Machine backup? If so, don't do this. Any files you put on that drive are not backed up by Time Machine (Time Machine cannot backup it's own drive. That would be like performing brain surgery on yourself.) If you are running out of space, get an additional external drive to store them on so that they can still be backed up by Time Machine.
    Here are some general ideas on how to free up space: http://docs.info.apple.com/article.html?path=Mac/10.6/en/8358.html
    The most common items that people tend to have that use up all their space are iTunes (Music/Movies), iPhoto (Pictures), and iMovie (Movies).
    You can move all 3 of these to an external hard drive if you like. Again, do not use your Time Machine backup drive for this purpose. That is for making a backup copy, not for holding the originals.
    Once you have another drive you can move the afore mentioned large items if they are indeed taking up a large amount of space.
    iTunes: http://support.apple.com/kb/HT1449
    iPhoto: http://support.apple.com/kb/HT1229
    iMovie: http://docs.info.apple.com/article.html?path=iMovie/8.0/en/19555.html
    Hope that helps.
