I am using the latest MacFUSE 0.2.1
MacFUSE Tools 0.17 r - 1 NTFS - 3G 20070207 Was these suppose to have automatic locale selection? if it did then it is not working ><. and the echo command wasn't working in terminal for some strange reasons. Edit: I figure out may be because my external name was too compliated. So to get around the problem you can manually create the ntfs-locale with the locale name you want in it. |

According to mailing list on NTFS-3G performance issue are related to MacFUSE rather NTFS-3G itself.

That said, I'm sure the same is true of MacFUSE. As I said before, FUSE isn't really intended for high-volume filesystems right now. Apparently I call the cops when I see people litter. |

On Linux the bottleneck is the disk, typically. That is, you can not notice if you use ntfs-3g or an in-kernel filesystem. The low performance on Mac OS X is probably due to lack of the buffer cache for block devices and MacFUSE's synchronous writes. More info and potential solution (ublio): http://code.google.com/p/macfuse/iss...id=65&can=1&q= Ntfs-3g is architected to exploit the Linux kernel's buffer cache and IO scheduler for high reliability and performance. This is one of the many reasons I prefer the hybrid driver naming against the user space one. The overall effect is the result of several user and kernel space subsystem intentionally designed cooperation. The lack of a component can result anomalies, such as low performance. Quote:
The optimization mostly refers to the high CPU usage which could be much less. E.g. 1-5% instead of the current 10-50%. There are only a few scenarios when the driver can't saturate the disk, e.g. if the disk is much faster (> 100 MB/s) relative to the CPU speed, or degrading performance writing several GB big file on a close to full volume, or very metadata intensive operations.

When MacFUSE will support asynchronous writes then the write performance may change significantly. |

Atm, MacFuse can't be compared with the fuse development under Linux. I just sit back with the latest macfuse/ntfs-3g stable and wait for an optimized package. |

Looks like NTFS-3G has reached an official 1.0, and MacFUSE website has a FAQ on NTFS-3G's slow write performance. Looks like this problem won't be solved any time soon...

All slow write performance issues aside, this is awesome!
Finally, we can make changes to NTFS disks. Many times, I just need to read from them, or make small changes like delete files or transfer smallish things. 1MB/sec is a lot better then not being able to do anything at all. It's livable. Most of my disks, external etc are NTFS because FAT32 can't do files larger then 4GB. Lately, I've been making some disks HFS+ since MacDrive for Windows is pretty good, but that's a hassle if the disk isn't ejected properly (MacDrive doesn't have a "check disk" utility to check HFS+, so they're mounted R/O.) NTFS-3g is very good software. It's amazing, in fact. It could turn NTFS into the next FAT - if everything can R/W NTFS without corruption (I never thought the day would come) then I don't see why not! Well, besides the fact that Microsoft could change the spec at any time.. ---- Update: I have observed performance for two local (IDE) NTFS disks (Seagate 500GB and Seagate 160GB) to be around 10MB/sec to 20MB/sec. Usually floating somewhere around the middle. That seems totally acceptable to me. Is it faster for me because the disks are local? I'm running MacFUSE 0.2.1 and ntfs-3g 1.0.

Upgrading to MacFUSE-Core-0.2.1 and running next to NTFS-3G 20070207 shouldn't break anything should it?

is there any way to mount a dmg image of an NTFS disk?
i need to restore this image. it was a backup made with copycatx. I am able to mount other ntfs drives with no problems. when I try to mount it i get this error: Code:
john-smiths-computer:~ johnsmith$ sudo /usr/local/bin/ntfs-3g /Users/johnsmith/Documents/"windows xp backup.dmg" /Volumes/windowsxp -o ping_diskarb,volname="windowsxp"
Bootsector checksum failed.
Failed to startup volume: Invalid argument
Failed to mount '/Users/johnsmith/Documents/windows xp backup.dmg': Invalid argument
The device '/Users/johnsmith/Documents/windows xp backup.dmg' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
john-smiths-computer:~ johnsmith$ mount ?
mount: ?: unknown special file or file system.
john-smiths-computer:~ johnsmith$ |

I'm having troubles getting write support on my Sweex externe hard drive.
I've tried the automatic package that circulates on the internet but no success. So I tried the more basic way as described earlier in this topic. It all goes well but in the last steps I encounter trouble (I'm not an hero in terminal). I get this message in the terminal. Code:
Joost$ ntfs-3g /dev/disk1s1 /Volumes/"Secundary CTU backup server" -o force ping_diskarb,volname="Secundary CTU backup server"
You must specify exactly one device and exactly one mount point.

After upgrading to MacFUSE-Core-0.2.2, I'm VERY happy camper. I managed to copy a 2.5gig Parallels virtual drive from HFS to internal NTFS drive & vise versa in under 2.5 minutes. This falls along the same time line as Fuse/NTFS-3G/Linux. Secondly, I can now mount my Parallels virtual drives residing on an NTFS host drive. We can now work on Windows guest OS and Linux Servers guest OS, in what ever host OS we prefer using as long as we have Parallels installed.
I don't know when these behaviors changed but I am definitely sticking with MacFUSE-Core-0.2.2 and NTFS-3G 20070207. |

Well, I'm still seeing about 1.1MB/s transferring from a local HFS+ drive to an external NTFS drive.
But, here's some good news. I've updated the Tools to finally work well with the new MacFUSE notifications. I know it's been a long time coming, but I'm a lazy bum. Also, I've built NTFS-3G 1.0, so here's the latest versions of everything:
As always, the normal .ntfs-locale and .ntfs-readonly files still apply; see the included documentation for details. If anything acts up, aside from known speed issues, please post here and I'll try to see what's going wrong. Enjoy! Apparently I call the cops when I see people litter.

Thanks for the new build! I agree that transferring HFS to ext USB NTFS is a bit slow. I did a tested on a 452MB ISO from ext USB NTFS to local HSF and it took exactly 5.5minutes. 452MB ISO from local HSF+ to ext USB NTFS to took 7min 20 sec.
Now I just have to make sure Apple didn't release a USB patch during 10.4's evolution. Quote:

I made an NTFS disk image (.dmg), and copying local files to that ran around 10 or 11 MB/s, which isn't bad at all. Seems to me that excessive demands are being placed on USB2.0 that slow it down, while it's not noticeable on the IDE and SATA interfaces used internally.
I'm on a Mac Pro with SATA drives. Apparently I call the cops when I see people litter. |

Having no background in this matter, the only thing I can compare with is FUSE/NTFS-3G under Linux since it's conception. I posted a Linux/NTFS-3G bench over at the Ubuntu forum and they say "it's about the average transfer rate that USB2 can accommodate". I guess time will tell. FUSE isn't even at it's .5 milestone yet |

I'll be going home to test out the new releases. As always, thank you for the binaries.
As for the external USB drives and speed problem, I should note that read/writes with FAT32, HFS+, and Apple's NTFS (this one, just with read capability) is quite fast with external USB drives, especially in comparison to MacFUSE + NTFS-3G combo's performance in my observation. I'll be reporting back with the new version's performance soon. Last edited by wesley96 : 2007-02-27 at 08:13. |

The performance seems to be a lot better now! Interesting. Moving 2.09GB's worth of video files, reading from the USB HDD took 29 minutes while writing to it took 32 minutes - 1.2MB/s for read and 1.1MB/s for write. Far better than 200KB/s write speed I got before. This feels quite bearable. Still about 10 times slower than with HFS+, but bearable.

Hi there,
Thanks for the builds! That makes the whole thing much more easier. The speed is not the only problem. In fact at the moment I don't care about the speed. Did someone tried to copy things on a NTFS disk with characters like äöüß oder other letters? it works great as long as you only use a Mac to read and write that files but if you use that disk with windows again... the file names looks very strange. the same problem also occur the other way around. There are also some other users at Macuser.de (a german mac forum) who has the same problem. CU AssetBurned |
