I had not used my venerable ThinkPad T400 for about 2 weeks. I booted normally but was told to run fsck manually because of errors.
I'm using 12.04 and the disk in question is ext4, a Samsung Evo 840, mounted
I ran fsck.ext4 on my / (mounted ro) and it fixed some errors:
- Inodes that were part of a corrupted orphan linked list
- Block bitmap differences
- Free inodes count wrong
fsck fixed these errors and the reports the partition to be OK.
Is it safe to use a disk after a successful fsck?
