ntfs 3g input/output error


I have a strange problem when I try to mount one of my windows 7 partitions. I have a centos 6.6 with kernel 2.6.32-504.1.3.el6.x86_64.

On the one hand, I cannot mount the partition normally, meaning that if I simply do it with mount, it says 'unknown filesystem type ntfs'. But it does work with the mount.ntfs-3g command. It works only to the extent that it mounts it. However, when I try to access any folder, it says 'input/output error'.

My Windows 7 works just fine, I've never had any problems with my partitions or my hdds. For a while it worked fine, but after some time I came across this.

I tried to reinstall it, but that didn't work either. When I type modprobe ntfs-3g it says that there's no such module and I cannot find 'ntfs' in /proc/filesystems.

Any suggestions?

maybe something is wrong with your OS installaction, try with unetbootin created usb to sort that out.

BUT FIRST:backup important data!

How about something like:
ntfs-3g /dev/sda3  /mounting/point
Look at
parted -l
lsblk -f

Alright, I seem to have posted a little bit earlier than I should have. I've just searched the internet a little bit more carefully, and I've found this:

It seems that ntfs-3g-2014.2.15-6.el6.x86_64 is simply broken. So I updated it to ntfs-3g-2014.2.15-8.el6.x86_64:

yum --enablerepo=epel-testing clean all ; yum --enablerepo=epel-testing update ntfs-3g

Of course, to do that, you need to have epel.repo installed first. Hope that helps anyone else who might come across the same problem as I did.

Thank you for your very prompt replies

It's fine now, I've just written a reply (before your post) and I said that I found the solution. It seems that the current ntfs-3g version is broken.


fuse, ntfs, ntfs3g
