Hi, Sorry about delay in replying. I am CC:-ing ntfs-user as other people may run into this problem and would want to have the answer in the archives. Hope you don't mind.

Are you sure the driver is compiled with r/w support? Type: "dmesg | grep NTFS" and it will tell you if the driver is compiled r/o or r/w. Assuming it is r/w then the mount should succeed. Again after mounting run: "dmesg | tail" and you will see any error messages it output if it failed to mount r/w. Assuming that worked, you cannot use dd just like that on a file as it tries to truncate the file to 0 size first and then extend it again. You need to use the notrunc conv option to dd, instead of "dd in=blah of=pagefile.sys ..." use "dd conv=notrunc if=blah of=pagefile.sys ..." and it should now definitely work.
