My ISC 2.0.2 has been producing the following NOTICE since I reinstalled it after repartitioning the hard disk: NOTICE: bad free block count in free list block on Primary AT Hard Disk unit 0, partition 4 mount: possibly damaged file system Partition 4 is /usr2, a 40M partition on a 200M IDE HD. The message is produced on booting the system, when it mounts this partition. Apparently, there is no other problem generated by the supposedly damaged file system. I am not an expert on system administration but tried to use the checkhdfsys sysadm script to check the partitions on my HD and all I got was a message saying that there were no partitions which could be checked by that script. The Famous Manual (for version 2.2 -- ISC gave me version 2.0.2 because version 2.2 does not support IDE drives, but this is a long story) says nothing about this message. How can I fix the bad free block count? Is it possible to fix it? Do I have to reinstall the whole thing? Another question is what is `gendev', the device which uses interrupt vector 5 on /etc/conf/cf.d/sdevice ? Can I disable it to avoid a conflict with my Microsoft Bus Mouse? The Famous Manual doesn't have anything on `gendev' either... Thanks in advance, J.R. Setti - The Transport Group, Civil Engineering - U of Waterloo

If the system is automatically mounted during start-up, it should be auto-unmounted unless you have some processes that are getting locked up on that partition, or have mounted something else on top of that partition. Anyway, this message is not a bad thing because the way that ISC works (with it's fast file system) you will always get this if the file system was not unmounted properly and it doesn't indicate any damage in itself. >How can I fix the bad free block count? Is it possible to fix it? You need to figure out why the partition is not being unmounted. >Do I have to reinstall the whole thing? Shouldn't have to. This, by itself, is not an indication of any problems with the system installation. >Another question is what is `gendev', the device which uses interrupt >vector 5 on /etc/conf/cf.d/sdevice ?

The Famous Manual doesn't >have anything on `gendev' either... gendev entries are part of the High Performance Disk Driver (HPDD) and all the extra entries will be removed when you configure it.
