NTFS write

Hello, I am unable to write to USB (External) drive formatted in NTFS format. Does anyone know if this is possible ?
Using iMAC w/ OS version 10.7.4
Thanks.

After purchasing a New IMAC, we ran into the NFTS problem. It was odd because this never happpened before on our old Apple. Tada. Remote Disk doesn't work, none of the old games work, migration assistant was of no help because our computer was too old, but this happened after hours of trying to figure it all out.
So today, day 3 of ownership and what we really received was another problem. We tried many solutions that didn't work but the final one did.
The external drive was a Seagate, went to their website download the file and restarted and it worked fine. Now able to read and write, on a disk drive that we used to be able to read and write with under the old computer.

It is safe to enable ntfs write support in Lion?

Hi,
I wonder how stable is the unsupported ntfs write feature of Lion?
http://forums.macrumors.com/showthread.php?t=785376
Has anyone tried this?
Thanks

There actually is no problem with running it with the display lid closed as demonstrated by the lid-closed mode…
http://docs.info.apple.com/article.html?artnum=86286
Just be sure that youo do not block airflow out the back of your MBP as this is the new exhaust point as opposed to in front of the display and the grilles when the display is open.
However, it's not recommended without an external display as there is no way to indicate its operational state. A running MBP in this state looks just like one that's off which can increase the chances of damage.

Ntfs write not working

when i try to write to my windows partition, it says "Operation not permitted" and "Permission denied" even as root! Here's my fstab!
/dev/hda1 /mnt/windows ntfs defaults,umask=0,rw 0 0
It works fine with captive-ntfs, but not with the write ntfs i compiled in the kernel![/code]

In the present version of the NTFS utilities, it is not possible to write to NTFS partitions. DO NOT WRITE TO THE NTFS PARTITION: You risk VERY serious damage to your NTFS partition if you write to it.
For more information about NTFS utilities, see:
Linux-NTFS Project
http://linux-ntfs.sourceforge.net/misc.html
WRT: Writing to NTFS volumes, here's a quotation from the FAQ at this site:
"3.2 Can the Driver write to an NTFS volume, too?
Not really, but if you only need to copy files from Linux to Windows on a dual-boot machine, see "How to write to NTFS" below for a possible way to work around the lack of write support. For write support in Linux, read on.
There are two drivers, currently. The original driver, in 2.4 has some write code in it, but it is extremely dangerous to use it. The possibility of destroying your filesystem is very high.
The new driver, introduced in 2.5.11, has some write code, but it's very limited. The driver can overwrite existing files, but it cannot change the length, add new or delete existing files.
Adding write support will take a long time. NTFS is built like a database. Any changes you make, necessitate making changes in many places, for consistancy. Make a mistake and the filesystem will be damaged, make too many mistakes and the filesystem will be destroyed. Also, the current developers are only working on NTFS as a hobby, during their free time. If you'd like to help, please email me: [email protected]
How to write to NTFS. If you are using a dual-boot machine and just need NTFS write support to transfer files from Linux to Windows, you can instead use a Windows driver for ext2/ext3 and, while running Windows, read the files from the Linux partition instead. This way, using two read-only drivers, you can still copy files from one file system type to the other."

External hd ntfs write from bootcamp windows

I have been using a PC and it recently died on me. I store many files on external drives. Now I am thinking of going to a Mac.
My question is if I use bootcamp and install Windows, can I read and (more importantly) write to my old NTFS external drives.
I understand that NTFS is read only on OSX but since bootcamp is formatting the Windows partition to NTFS, will I be able to read a write to those external drives if I am in Windows using bootcamp.
Thanks.

You want yes or no.
I am giving you that but also other things to consider.
For OS X you can always use them by buying Paragon Software NTFS for Mac OS X which I have used and use $19.
USB2 - never used it for disk drives, newest Macs have USB3 and Mac Pro most people use FireWire or eSATA or just pop a drive in one of the four drive bays to access and use it which will work fine.
For Windows you can migrate your Windows into Boot Camp by going through and buying WinClone.
Use WinClone for Windows
http://www.macwindows.com/Winclone-4_1-can-create-Boot-Camp-installer-package.ht ml
Yes you can use them as is. But why use USB2 when you are talking about a Mac that has drive bays for extra storage??
NTFS drives on USB, when accessed from within Mac OS are iffy and even read-only does not work well.
They should work. I just want to be sure:
You have a Mac Pro tower and not a notebook MacBook Pro (we get tons of such users posting here)
And if you want to use an interface other than the very slow clumbersome USB2.

[Solved] Very strange problem with kernel-modules & NTFS write speed

I was getting very low copying speed when copying files to NTFS partitions, around 8-10 MB. But, when I commented the modules section in /etc/rc.conf file, the speed dramatically improved upto 5-6x.

Sorry for replying late.. Was very busy.. So, the thing is that I disabled every module & loaded only microcode & powernow-k8 in /etc/rc.local. Now, I'm getting good speed while copying data but the problem is that the processor is running & full speed i.e. 3.0 GHz. I checked it via cat /proc/cpuinfo. Also, there is a message in the bootime, that i'm posting here..

FATAL: Error inserting fuse (/lib/modules/2.6.9-42.ELsmp/kernel/fs/fuse/fuse.ko): Invalid module format..
i also tried other versions of fuse, same errors.

dnot know what happened? plz advise.

Try the following steps...

How can I write to a ntfs formatted drive?

I know there are some third party apps for a fee but this seems like a simple enough and popular request that Apple should address. Can you tell me if apple has a solution for this?
I appreciate your help.
Thanks,
John

No Apple solution (well, the solution would be for you to only buy Mac stuff and reformat your hard drive to Mac ).
NTFS drivers for Macs (there may be others):
Paragon NTFS - http://www.paragon-software.com/home/ntfs-mac/ - recommendation: https://discussions.apple.com/message/18708633
Tuxera NTFS 2012.3.2 - http://www.macupdate.com/app/mac/33122/tuxera-ntfs
NTFS for Mac OS X 9.5.3 - http://www.macupdate.com/app/mac/26288/ntfs-for-mac-os-x
There used to be NTFS-3G which I believe was free, but it looks like it is now Tuxera. Maybe an old version would work (or maybe not).

Can't write to NTFS partition [RESOLVED]

I want to use an NTFS partition to contain all of my data.
I created a directory in ~ and mounted the NTFS partition to that directory.
I can read it but I can't write to it.
How do I get NTFS write support? Do I have to manually load a kernel module or something like that?

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.

How can i write on ntfs volume ?

Can you help me to mount ntfs volume in R/W.
Thank you!

But if one day Apple add support of ntfs write
I seriously doubt Apple will ever do that. It isn't worth their time to put that much development into supporting NTFS write capability.
Paragon went through Microsoft's validation testing and approved it.
Note that I already stated NTFS-3G is free. Also note that there are two different versions of NTFS-3G on the page I linked to. Tuxera NTFS is not free, but is twice as fast as the free version towards the bottom of the page. Both support 64 or 32 bit OS X startup.

Why can my friends MBP write to a NTFS external hard drive and mine cannot?

I bought and formatted my friends 13" 2012 MBP which is running on Mountain Lion and I did not download any extra programs or software to enable his MBP to write on a NTFS external but for some reason he is able to write to it and I cannot, I have a 15" 2011 MBP. I assumed it was the OS since I was running on Lion, but I just upgraded to Maverick last night and it still won't let me write.
So what's the deal? How can he write to it while I can't?
Thanks,
John

There is (was, don't; know if it still works) a hack you can use to enable NTFS writing on OS X. However as it was never officially supported by Apple it really is best to consider this experimental and not rely on it. If you need to use NTFS drives for real work you should look into the many 3rd party extensions.
For the native OS X hack see:
How to manually enable NTFS read and write in OS X | MacFixIt ...
How to Enable NTFS Write Support in Mac OS X - OS X Daily
10.6: Enable native NTFS read/write support - Mac OS X Hints
among others. But as I wrote this is really a parlour trick.

I cant write on NTFS!

hello
i have a imac with a external hard drive (cgate) that it is not for mac!!
i active ntfs write with terminal: sudo nano /etc/fstab ...
it was active but now it is inactive!!!!!!
when i write that again it is on terminal but in info of may drive see:read only!!!

I suggest reformatting the drive to HFS+ as long as there is no need for a PC to access it. NTFS is a proprietary file system created by Microsoft for Windows. They have never released any specification on how NTFS is to be implemented so all of the software to use NTFS on OS X or Linux are reversed engineered implementations to NTFS.
Reformatting the disk will destroy all information on the disk. So backup first.

Windows NTFS network drive no longer able to edit files in Osx 10.9

In the OSX 10.8x and before, the network drive hosted by Windows 2008 server in our .local domain was able to be modified by my imac under a local user account with the same user name without any problem. The only issue was not able to join the AD due to the existing .local domain setup. Upon upgrading to OSX 10.9 today, the network drive still connect properly, and the files on the share drive is still able to be opened, read, copied and deleted as before. However, any attempt to save the changes to the opened file display an error message saying that it is been locked and I have no privilege to modify the file. The funny thing is now that the mac computer is able to join the windows AD without problem, although under the network account, the same problem exited. Something has to do with the SMB right/ share has been changed in this release. Anyhelp on how I may resolve this problem?

I'm hoping you or someone can solve this. We're using Tuxera to add SMB NTFS write capabilities to Mavericks and it works great for everything ... except for iWork 2013. iWork 09 still reads and writes perfectly, as does every other app I have on my Mac.
At this point, I fear using iWork 2013 in a mixed Windows/OSX environment is dead if your server is NTFS. It's another quiver in Microsoft's argument that iWork is for children only. Despite all the griping about deprecated functions in the new iWork, there's no show stoppers as far as I'm concerned, and I use Pages, Keynote and Numbers in serious ways daily.

HELP !!! External hard drive MBA/PC read/write

HELP !!! I have justbought an MBA and want to be able to read/write to an external hard drive netween both the MBA and PC. Help! Do I need to partition the hard drive or is FAT (FAT 32 ?) format still the best method? Grateful for any advice

Welcome to the Apple Support Communities
As you know, OS X hasn't got NTFS write support. If your external drive is formatted in NTFS, you can install a third-party application to be able to write in the external drive like Paragon NTFS.
However, in my opinion, that's not the best option. OS X supports two filesystems which are compatible with PCs: FAT32 and exFAT. FAT32 is a filesystem which is limited to files smaller than 4 GB, and exFAT is like FAT32 but without this restriction so, if you can, format the external drive with exFAT.
To do it, first you have to copy all the files you have on the external drive to a Mac or PC, because you will lose them from the external drive. Then, format the external drive on a PC. If you do it on a Mac, PCs won't recognize this external drive. exFAT is compatible with Windows XP SP3 or newer and Mac OS X 10.6.5 or newer

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.
