Post Problem exactly with Vista or ntfs-3g ??
Some time ago I was downloading some files with a torrent client on Linux. I had a power outage. Since then I had no problems with anything on the partition (formatted with NTFS of course) under Linux. But under Vista crap every time i tried to write something to specific folder it had a BSOD with ntfs.sys problem. Even running chkdsk didn't work so my question is what could be the problem as I cleaned log file under linux (it didn't help). As a last resort I copied whole content of the disk to another disk (it took a bit as it was about 300GB of files) and then copied back on freshly formatted partition on that "faulty" disk. Disk was and is ok and it was definitely a problem with a filesystem, what could the ntfs-3g have done to cause a BSOD under Vista??

Power outage can cause this, independently of the used file system.

Hello,

Same problem here, It seems to be caused by sparse files. Whenever i create that file in Linux, currently only reproduceable using Bittorrent on both sides, with different programs azureus(linux, windows) and utorrent(windows).

No power outage while being in Linux.

Please take a look at the minidump that was created. I now selected to create a file filled with zeros, that apparently solved the problem.

Using last advanced version, but also happened with one of the last stables.

(minidump) http://rapidshare.de/files/41132479/Min ... 2.dmp.html

(OFFTOPIC) also detected that VMware is locked (writing) in Linux much more in the 1TB that in a 100Gb drive. I cotig several times the drive, created a fixed disk, no solution and no clue. Any test/trace you may want?

Best regards.

VistaX64 Ultimate, 8Gb, all drivers updated, happened on a RAID1 and on a single 1TB drive.

Vista crashes with sparse files is a known Vista problem which is independent of NTFS-3G. People can reproduce it purely on Vista too. Please report it to Microsoft. The more people do, the better chance they fix it sooner. You can find more information here:
https://bugs.launchpad.net/ubuntu/+sour ... bug/279017

About the VMware problem: if you think it locks then please submit a bug report to VMware. No program lockup is reported with any other software.

I also suggest to check for hardware problems by diagnostic/testing tools and in your logs. It could be that both of your problems are caused by a hardware problem: http://ntfs-3g.org/support.html#ioerror

What i meant by "lock" is ntfs-3g at high cpu% for some time, and repeating after some minutes. Disk was defragmented and vdisk fixed size.

Anyway, great thanks for developing ntfs-3g.

I seriously hope you're using one of the very latest NTFS-3G releases: http://ntfs-3g.org/releases.html

VMware uses a sparse file which means the extent list of the file is highly "fragmented" (data, hole, data, hole, etc). This list must be regularly decompressed and compressed which results the higher CPU use.

If VMware preallocated the entire image then this performance issue could be avoided. Using fixed sized image is not enough.

We will also optimize the driver for such scenarios but it's not yet the highest priority at the moment.
