I have 1TB external HDD, the file system is NTFS
and i need to convert it to Ext3.
My operating system is Ubuntu 10.10
is there anyway to do so without losing my data??
Thanks for your help
There's no way I know of to directly convert between these two filesystems.
Alternatively if you don't have a spare disk big enough to do that you may be able to
If you have spare room on the drive, you can shrink the NTFS partition using something like partition magic.
Then create a new volume group, logical volume and filesystem in the remaining space. Copy over your data.
Once you are sure your data is successfully copied, delete the NTFS partition, extend your volume group to reclaim space under ext3.
I think taking the disk-to-disk route is the way to go. Fundamentally, it is certainly straight-forward enough to create another partition, assuming you have room, but the far safer approach is to offload data to another drive, re-build your source disk however you want, and put data back.
