Package: e2fsprogs
Version: 1.39+1.40-WIP-2006.11.14+dfsg-2
Severity: normal
Error messages add one to a too low 'lastblock':
% badblocks -vs /dev/hdb1 1 2
badblocks: invalid blocks range: 2-2
% badblocks -vs /dev/hdb1 1 99
badblocks: invalid blocks range: 99-2
Too high values vary more:
% badblocks -vs /dev/hdb1 200 3
badblocks: invalid blocks range: 3-0
Thanks for your bug report. The following check has been checked into
e2fsprogs, and will be in the next release of e2fsprogs.
