I added cc: freebsd-fs at freebsd.org as it's about file systems & Ext2 & offsets.

An extract re FS.

] FreeBSD will by default not accept the Finnsat generated partition
] for mounting. The trick is that Finnsat creates partitions with
] slack alignment. FreeBSD knows that a live ext2fs has to be a
] multiple of 4kB, 4096 bytes in size, i.e. 8 disk blocks, 8*512
] bytes. If the partition size is not perfectly aligned, FreeBSD does
] not allow read-write mount to an ext2fs instance. With all likelihood
] it might be a broken file system. Why should FreeBSD help making
] things worse?
] So, you will have to adjust the partition size such that its length
] will be a multiple of 8 disk blocks. The tool for this is gpart
] (geom partition) which both modifies the partition tables and shows
] their contents. First use the command

Thanks Jukka,

I've bcc'd a friend who I discussed Humax TV recorders with a while
back, on similar issues, some time when I'm visiting the town where
my 3 Humax owner friends are, I hope to find time to experiment
with my USB to SATA converter.
