![]() Whether you write to your Windows C:\ partition or a shared NTFS data partition, be aware that if you are using Windows 7, and Windows 7 is in a hibernated state when you write to the NTFS partition from Ubuntu, you will lose all your changes. If you have data which you want to access regularly from both Windows and Ubuntu, it is better to create a separate data partition for this, formatted NTFS. Since it is all-too-easy to accidentally modify or delete files which are essential for Windows, it is advisable to mount your Windows C:\ partition as seldom as possible, preferably not at all, or read-only by configuring /etc/fstab (see below). Consequently, important hidden system files in the Windows C:\ partition will show up if this is mounted. Ubuntu will show files and folders in NTFS/FAT32 filesystems which are hidden in Windows. You will also see FAT16 on other devices. These partitions are normally formatted with NTFS, but are sometimes formatted with FAT32. This is still on 2012.1.15, I didn't try the latest version after the old version worked, but I suspect the problem is indeed with the UBLIO and thus it should be disabled by default (at least) or perhaps even annotated as BROKEN.Ubuntu is capable of reading and writing files stored on Windows formatted partitions. Surprisingly, it helped! I was able to fill the NTFS partition until "No space left on device (28)" without getting "Input/output error (5)". Then I've searched our Bugzilla and stumbled upon this PR, which suggested to disable UBLIO, albeit for another reason. I've tried that but the problem did not go away. Today I've hit it again and tried to google some solution.Īt first, I've found this rather old Debian bug which suggested that downgrading to version 2012.1.15 might "fix" it. I think it occurs more often when partition becomes closer to full. To sum it up, I think devel/libublio doesn't need fixing/patching but RECREATION/FORK with current port as a good template.įor quite a while (several years), I've been occasionally getting weird problems with writing to NTFS partitions: rsync(1) would abort file copy with infamous "Input/output error (5)" message. Libublio has been created at 2006 and file has in it name 2007 Sugar on top is it's size of only 17K, so no one is going to get lost in code. It uses BSD style data structure macros via queue.h(taken from OpenBSD as is) and tree.h(taken from FreeBSD with some mods) Regarding it's code it is all from *BSD, so no linux "translations" required. Library of only 17K in size used by BSD and derivatives including Mac OS X.Įxists only because BSD doesn't have a block, but character devices. Regarding it, all points to it's obsolescence: Then new bug dedicated to devel/libublio should be opened and resolved. , ok you get the point.īased on above facts, this Bug 206978 can be closed, as well as Bug 194526 and all other submitted bugs relating to libublio if existing. ![]() Second or higher attempts would catch silent errors: $ diff -rq. So I had to use diff tool for verification and it too would sometimes had an issues, like:ĭiff: /mnt/ntfs/file.mp4: Operation timed out In worse case scenario, some files completed without emitted errors, but i.e file of 4G ended up being copied as 1.3G file Second copy attempt of above file succeeded. I.e During copy of >100 GB files from RO mounted ntfs:Ĭp: /mnt/ntfs/file.r05: No such file or directory Regarding See Also: Bug 194526 (sysutils/fusefs-ntfs: ntfs-3g with libublio lost files) Libublio doesn't ONLY breaks mkntfs, but it also makes I/O operations on mounted ntfs unreliable. Tested on exactly the same HW with same CMDs. ![]() Without libublio, ALL issues from my previous post are gone! ) # gpart add -s 120g -t ms-basic-data ada0Ĥ1943080 251658240 ada0p2 ms-basic-data (120G)ġ1.2-RELEASE-p9 i386 with fusefs-ntfs-2017.3.23 and WITHOUT libublio (at a time of a previous post, there was no option to choose) # mkntfs -vIf -p 40 -H 16 -S 63 -L 'NTFS_slice' /dev/ada0p1Ĭluster size has been automatically set to 4096 bytes. 11.2-RELEASE-p4 i386 with fusefs-ntfs-2017.3.23 & libublio-20070103_2 (deinstalled BOTH and recompiled JUST NOW)Ĭompiling sysutils/fusefs-ntfs AUTO installs devel/libublio (no option)Īccording to test and fixes(?) below, there are TWO possible reasons for failure:Ģ) Partition/slice's length spreading to the end of deviceįailure always occurs by hanging at 'Creating backup boot sector.', so that is a place to look at in the source code.
