We all know that one. IB often hangs when writing cache and corrupts the sensitive FFS.
If you got RAM (>64MB) then re-direct cache to ram:.
DO NOT SPEND MONEY ON PFS3! Go with Smart File System SFS. It's free and have never ever caused me any trouble (I kicked out FFS a long time ago). Note that SFS gives a huge leap of HDD performance if you got a modern HDD (yet another reason to dispose of FFS). FFS partitions can be converted to SFS without hassle.
