I have a dual boot system with Vista and Ubuntu. I use Ubuntu 99% of the time and have the Windows partition mounted for read/write.
I just ran Diskeeper 2008 while in Vista to "clean up" the disk a bit. I ran a boot time defrag as well as defragging the C: drive a few times.
However, back in Ubuntu I'm no longer able to write to the Windows partition. Any ideas what gives?
A little more info: the partition is NTFS as you'd expect. Running
mount on Ubuntu shows the partition is writeable, I think:
/dev/sda3 on /media/OS type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
Here is my /etc/fstab if it helps. The last line is the Windows partition.
proc /proc proc defaults 0 0 # Entry for /dev/sda5 : UUID=dc57d1f6-e720-47ee-86e2-c24fa4e24dff / ext3 relatime,errors=remount-ro 0 1 # Entry for /dev/sda6 : UUID=fdf33781-b661-4216-a2a2-6fe61e27f399 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 /dev/sda3 /media/OS ntfs-3g defaults,locale=en_GB.UTF-8 0 0
As previously noted in my own answer, I thought I'd solved this by running chkdsk in Windows across the drive. However, I'm still getting occasional errors, mainly when using Transmission (Bittorrent).
If I run nautilus as root, go to a folder on that partition and view the properties of some files, I get this error:
