FYI, I was chatting with Dominic Williams on IRC yesterday, he had an 0.7.4
install with the same problem see error stack here http://pastebin.com/YasPtEYj
He has not run nodetool scrub but I think it the 0.7.4 install had been there a
while so I the data file may have been fresh.

Remove main-f-5-{Index|Filter|Statistics}.db files. They make no sense
without a Data file and
Cassandra always make sure it removes those before the Data file (that
while it gets confused if it
finds one of those file without a data file).
Note that your error was with the sstable main-f-232-Data
Thanks for the answer Aaron.
There are Data, Index, Filter, and Statistics files associated with SSTables.
What files must be physically moved/deleted?
I tried just moving the Data file and Cassandra would not start. I see this
exception:
WARN [WrapperSimpleAppMain] 2011-04-11 12:04:23,23
The WARN messages are the "emergency pressure valve" kicking in, search for
that test in conf/cassandra.yaml. These are settings to reduce the chance of
going OOM. It means you should take a look at your memtable and cache settings
as you are getting close to running out of memory.

It appears we have several unserializable or unreadable rows. These were not
fixed even after doing a "scrub" on all nodes - even though the scrub seemed
to have completed successfully.
I trying to fix these by doing a "repair", but these exceptions are thrown
exactly when doing a repair.
