Backup'ing a wrong partition size

Postby Thorun » 14 Jun 2008, 10:12

Hi.

I have used partimage and this rescue CD with great success the past few years. And allways without any problems.

Now i will backup my girlfriends computer and i can mount the ntfs-drive, locate the /dev/sda2 device and go to the partimage-part without problems .

But when i'm going to backup the C: , partimage tells me, that there is 42% used of the C: partition (25GB total). That is aprox. 10GB used space. But both in gparted and several other programs tells me, that there is only used ~5GB. Not 10 as partimage tells me.

After i have backed up the c:, my backup-file is comperessed with the middel-option - but contains 6GB of data.


Why isn't partimage registrering the right amount of used data?

Regards
Rune.

Denmark.





EDIT:

The computer is an Acer Travelmate 5510.
Windows XP Pro as OS.
Newest version of System Rescue CD.
Using the startx-boot.

defragment the drive and check again. ntfs is very sophisticated and sometimes the linux tools are buggy upon it.
