I have three partitions: one with Ubuntu 12.04, the other is a data partition (the largest of the three) and the last one has Windows 7.
First I installed Ubuntu, then I formatted the data partition as ext3 and chose it as my home folder. Like a month after I installed Windows 7 on the third partition, and realized that it can't read the data partition (ext3). So I just want to reformat it from ext3 to ntfs with gparted.
I thought of just copying the entire home folder (with hidden and system files) to an external hard drive I have, unmount home, reformat the partition to nfts, and just copy everything back and mount again. But I don't know if this will be the wise thing to do.
