I have Windows 7 64b installed and recently also installed Ubuntu 12.04
Problem: 2 of 4 Partitions on the same harddrive are not visible in Windows.

Here is some info:

$ df -T

Filesystem     Type     1K-blocks      Used Available Use% Mounted on
/dev/sda7      ext4      77535900   8437852  65159316  12% /

/dev/sda1      fuseblk   51199120  49790596   1408524  98% /media/Windows




$ sudo fdisk -l

/dev/sda7       819202608   976751999    78774696   83  Linux

sda7 and sda6 are not visible in Windows.
I don't care about sda7 too much, but I really need sda6 on both OS's

Thank you!

  • /dev/sda6 is configured as a *nix swap space you would be able to use in Windows, or at least I have no idea how it could be possible. I am assuming you are trying to use the same space for both OS's? /dev/sda7 is configured with ext4 there are tools that will allow you to mount it under 7 but I am not sure how reliable they are.

    Why do you think windows should "see" linux filesystem? There's very bad situation in W with filesystems: it knows just "three with half" (vfat, ntfs, exfat and partially udf). The same with swap. If you computer is powerful enough and you use W just for 1-2 applikation, it's better for you to setup W under VirtualBox.

  • Define 'invisible'. Where are you looking for these partitions in Windows and what did you expect to see?

  • A Windows tool was able to show 2 Partitions where the files are not accessible. The partitions also don't show up in any file explorer. I expect to see at least sda6 since it still has all data that was there when I used it on just Windows. I can see all files under Linux.

Here is the solution, thanks to @Eddy_Em!

My sda6 partition was a Windows file system and still had all files on it.
I must have accidently marked it as 'swap' during the installation of Ubuntu.
The good thing is: The partition was not changed, it just had a false flag.

Changing the filesystem type back to NTFS (using linux) does the trick:

$ sudo fdisk /dev/sda6
> Command (m for help): t
> Partition number (1-7): 6
> Hex code (type L to list codes): 7
> Changed system type of partition 6 to 7 (HPFS/NTFS/exFAT)
> Command (m for help): w
