This data should already be in the cache if you're running with caching turned on, reducing the number of reads while writing.īTW, I, too, tried the new fuse-ext2, with the dmg package installer: seems to work very well, indeed (at least on an Intel Mac with Leopard)! It receives all data from MacFUSE in blocks up to 64 KiB in size, and the current default cache block size (provided that caching is enabled) is 64 KiB as NTFS-3G has been determined experimentally to perform best under these conditions.ĭata needs to be read even when writing to a volume, for looking up the next block in the file, allocating additional space and so on. You shouldn't expect NTFS-3G to completely match or surpass the performance of a well optimized kernel driver like OS X's HFS+ driver though, but we should at least be able to achieve a 1:0.9 or 1:0.95 performance ratio to HFS+ in the future.Īs to what blocksize NTFS-3G uses, that depends. Your performance numbers are roughly what one could expect from the current NTFS-3G build, but we're working on redoing the I/O layer for the next version (hopefully).Īt that point, NTFS-3G should be able to better match Apple's HFS+ driver in performance. As for myself, I'm permanently running with caching turned on for all my drives. This flexibility has rendered the so called 'stable' build obsolete. for instance you may see data integrity for your internal drive in the event of a system crash as high priority, while you may be more interested in high performance when communicating with external USB drives. You can also turn off caching for individual drives. However, under normal operation (no system crashes, no power cuts, no accidentially disconnected cables prior to unmounting the volume.) your data is equally safe in cached mode as it is in uncached mode. You will achieve the same amount of data safety as the old 'stable' build, at the cost of lower performance numbers. This is useful if you're worried about losing data in the event of a system crash. The caching layer isn't at all experimental, but if you're concerned about data integrity you can turn off caching through the preference pane in the new 'unified' build. The 'stable' build was in the end built from the same code base as the 'ublio' build, but with a few features turned off at compile time. 'ublio' was unfortunate, and didn't at all reflect the actual maturity of the code. Using the command line utility bless (see man bless for more information).Intel users only: Install the rEFIt boot manager for better control of the boot process.Holding down the Option key during boot (or Alt for non-Apple keyboards).It seems that this issue can't be solved, but only worked around since the Startup Disk preference pane doesn't recognize file system drivers that are not provided by Apple. Disabling or uninstalling ntfs-3g brings them back. After installing ntfs-3g, all NTFS drives will disappear from the "Startup Disk" preference pane.Packaging, patching, Mac OS X-related development and testing is done in the context of my development efforts with the Catacombae projects. If you are having problems with NTFS-3G, write a forum post about it in the NTFS-3G Forum (or post a question as a blog comment if you're just unsure of how things work). Information on how to install and use NTFS-3G for Mac OS X can be found in the User Guide. The package has been tested with Mac OS X 10.4.11/Intel and Mac OS X 10.5.6/Intel. Mac OS X 10.4/10.5, running on an Intel or PowerPC computer.The 'legacy' build will probably be removed in the future, unless anyone has a good reason that it should be kept maintained.Ĭertain patches such as the caching layer are omitted in this build. We now have a 'standard' build, and a 'legacy' build in case anyone is still interested in the limited feature set of the old 'stable' build. The 'stable' and 'ublio' labels are dropped.When asking for confirmation before mounting a volume with an unclean log file or a hibernated volume, the dialog informing the user that the mount succeeded has been removed.The NTFS-3G system preferences are now retained between installs, and limited support for automatically repairing damaged NTFS-3G settings has been added.New preference pane version, 0.9.8: The user can now choose to always mount (recover) uncleanly unmounted volumes without user confirmation. Simplified install procedure: NTFS-3G now installs MacFUSE (2.0.2/2.0.3) with it, so that users don't have to download two different packages to get read/write NTFS support working.
