So I run fsck, and it reports
FATs differ but appear to be intact. Use which FAT ? 1) Use first FAT 2) Use second FAT
Choosing either one gives a long list of errors like
Cluster 1471730 out of range (164977891 > 1980013). Setting to EOF. Cluster 1471732 out of range (252397720 > 1980013). Setting to EOF. Cluster 1471734 out of range (18601458 > 1980013). Setting to EOF.
Then it says,
Reclaimed 93886 unused clusters (769114112 bytes). Free cluster summary wrong (1034047 vs. really 1221912) 1) Correct 2) Don't correct
If I choose (1), it just exits with no action:
Leaving file system unchanged. /dev/sdb1: 53 files, 758100/1980012 clusters
So how do I fix this?
