to

But after testing, I still got the same errors:

EXT3-fs error (device ubda): ext3_lookup: deleted inode referenced: 964816
EXT3-fs error (device ubda): ext3_lookup: deleted inode referenced: 964862
EXT3-fs error (device ubda): ext3_lookup: deleted inode referenced: 964786
EXT3-fs error (device ubda): ext3_lookup: deleted inode referenced: 964815
