Currently I have an Ext4, 1TB hard drive in a Linux system where personal files are saved. The system files, including home folder, are in another (SSD) drive.
I want to format the SSD to install Windows, but then the Ext4 drive would at best be read-only (of course I am sorry for having chose Ext4 back then..)
Then I got the following idea, but I don't know how dangerous that may be:
- Make sure to free a lot of space and leave the 1TB disk with at least 40% free space;
- Use GParted to shrink the Ext4 partition;
- Use GParted to create a NTFS partition occupying all free space;
- Mount both partitions and move some folders from Ext4 to NTFS
- Unmount both, srink Ext4 further, and expand NTFS to catch up with newly freed space;
- Repeat steps 4 and 5 until every file has been transfered;
- Delete (now empty) Ext4 partition;
- Expand NTFS to occupy all available space.
Specifically, I'd like to know about risk of losing some files, or worse, losing all content from a partition or from the whole disk.
Besides that, I'd like to know how I could perform this operation in a safer way, if you think that is more recommended (I don't have spare disks around. I have a paid Dropbox Account, bit still I'd like to spare the weeks I would need to upload everything.
