Can't Access NTFS HD with windows...

[c0m4ndo45]

I was able to access the HD normally but then i had hardware problems and had to replace motherboard. Then, tried to start windows 7 and had bsods and such (problems probably related to new MB) so i have to format and reinstall w7, but i want to back up stuff and now when i booted up from linux (which still works, same installation as before) it does not open the partition anymore, with the error: According to mtab, /dev/sda1 is allredy mounted on /.

I googled for this problem, heard about some saying to delete some entry on mtab or something like that, but i don't know what to do.

Here's my mtab, in advance:
/dev/sda1 / ext4 rw,errors=remount-ro 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
none /sys sysfs rw,noexec,nosuid,nodev 0 0
none /sys/fs/fuse/connections fusectl rw 0 0
none /sys/kernel/debug debugfs rw 0 0
none /sys/kernel/security securityfs rw 0 0
none /dev devtmpfs rw,mode=0755 0 0
none /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0
none /dev/shm tmpfs rw,nosuid,nodev 0 0
none /var/run tmpfs rw,nosuid,mode=0755 0 0
none /var/lock tmpfs rw,noexec,nosuid,nodev 0 0
none /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0

Thanks for the assistance.

Re: Can't Access NTFS HD with windows...

Do you only have one hard disk drive? If there are more than one, you need to go into BIOS and make sure the sequence is the same as it was before (i.e. that /dev/sda is the same physical device as it used to be).

When you reinstalled Windows, if you let it format the partition, it may have changed the UUID. So, depending on how you have /etc/fstab set up to boot it, it may need to be changed to the new UUID.

I have more than one, windows 7 is in one (but i have not reinstalled/formatted it, its still broken and i have to back up things before i format and reinstall).

well, there's 2 HDs total, the sequence was changed when new MB installed, but then grub was not working, so i changed it and grub worked again... so i believe the sequence is now same as it was before.

Re: Can't Access NTFS HD with windows...

It's good that you fixed Grub, but I think there's still some issue with the enumeration of your NTFS partition, either the sequence number or the UUID.

If you open a terminal and run

sudo fstab -lu

you can see what Linux thinks it is, then check /etc/fstab and see if it matches. Use

sudo blkid

to get the UUID number if you need it.

Re: Can't Access NTFS HD with windows...

fstab gives command not found

blkid gives 3 entries:
/dev/sda1 ext4 where linux is
/dev/sda5 backup which is the backup partition for the windows installation (in the same HD as linux is) - this one is working.
/dev/sdb1 , only shows UUID and type ntfs. I suppose this is the HD im trying to access?

etc/fstab file only has:

proc /proc proc nodev, noexec, nosuid 0 0
/dev/sdb1 / ext4 errors=remount-ro 0 1
/dev/df0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0

puhh -- I am a dunce!

sudo fdisk -lu

is the right command. I should be drinking ....

Re: Can't Access NTFS HD with windows...

There seems to be some confusion about your set up.

You state "/dev/sda1 ext4 where linux is"

but your fstab disagrees with you:

"/dev/sdb1 / ext4 errors=remount-ro 0 1" means THIS is where linux is.

Just to be sure:

do sudo fdisk -lu and compare the output to the results of mount.

The fdisk command will list all your partitions on all drives and the mount command will tell you what is mounted where. Post the output of those two commands and we'll go from there

Re: Can't Access NTFS HD with windows...

I have booted using the live cd feature and made my backup, and am now installing w7. I will then recover grub and check that again, that may take a while, tho. But if the problem persists i will do that and come post again.

Thanks for the help so far, tho! Much appreciated!
