You don't need new disk or partition to do so. Just install FUSE 2.5.2 and ntfsprogs 1.13.0 then
Code:

mkdir /mnt/ntfs-test
ntfsclone -o ntfs-test.img /dev/ntfs-partition
ntfsmount ntfs-test.img /mnt/ntfs-test

and you're ready to test NTFS write support in /mnt/ntfs-test. Your real NTFS partition won't be affected. BTW, if you don't have enough space for a full clone image then you can use ntfsclone --metadata but then all your data will have only zeros in the cloned image.

If you don't have NTFS partition at all then you can still test it:
Code:

mkdir /mnt/ntfs-test
touch ntfs-test.img
mkntfs -fF ntfs-test.img 10000000
ntfsmount ntfs-test.img /mnt/ntfs-test

I'll report back here but if anybody has any suggestions please feel free to make them.
Done :-)

Thanks igu for these info, I will try it as soon as I reboot under windows (when, thats the question). I wouldn't really like to run things in userspace but I'll maybe try.

OFF TOPIC

Hi Davcefai, do you know iozone?
I've been doing some tests on Ext3,FAT32,NTFS,ReiserFS,XFS with iozone for read/write speeds for different file size/record size. I then generate some 3d graphs using OpenCalc.
Would you be interested to make some tests for benchmarking these filesystems?
On my computer,the results do not show so much differences between all, but there are so many combinations (filesystem mounting parameters,iozone parameters,file size,record size,cpu) that it's not easy.

I think I will open a thread in general if somebody is intersted/have time in testing on their configuration.
