Back in the old days of PC-DOS 3.1, computers are much simpler than today's. I can learn a lot of how File System works with tools like PCTools, Norton Disk Doctor, and debug.com. Have been working exclusive in corporate database application area for over a decade, my knowledge of how these stuff work is diminishing. Standard-clean OS (Windows, Linux) installation is all I can do now. And it starts to cause me many data-loss troubles, when I have to perform something that I don't have much insight, such as install and remove peer linux os or move and resize partitions.
I'm looking for books, web resources, or communities where I can educate myself on how various file system works, for which I can have in-depth answer to questions such as:
- How to remove ubuntu and grub2 ? (I recently did that, but with a lot of frustration when I was not really sure what I was doing and confront with some scary error message like "Missing BootMgr"
- What kind of disk-partitioning operation can be performed non-destructively, and why ?
- What is Active partition ? Primary Parition ? Extended Partition ? How it stored on the disk.
- There are many free partitioning tools out there, which one is safe to used ?
- NTFS, Ext3, Ext4, .. What the differences ? How to choose it wisely.
