I have an XFS partition, which is
1) Mistakenly quick formatted as FAT16.
2) At first, I couldn't see in "fdisk -l" that it is set to FAT16, instead of Linux. Hence tried to fix it with xfs_recover. xfs_recover returned 0, and mount operation succeeded; but mounted fs size appeared as 20GB (despite it is 350GB) and almost every the file is missing.
3) Later set the type of /dev/sda1 (the only partition in /dev/sda) to Linux, re-run xfs_recover, but nothing changed.
I open the system with Knoppix, and below are the details of the current status. I need urgent help to recover the files. I will be really, really appreciated for any help!
