What you call 'fact' is simply limited information as to what is going on.

'dd' a 'before' and 'after' copy of the first MB or so of it to some other media.

Go onto that media and diff those two files.

Take a hex editor to the area(s) of difference and see what is actually 
happening on-disk.

Likewise look into your logs and see what ~/all.log, ~/messages, ~/dmesg and 
~/console.log have to tell you.

DragonFlyBSD just might be a tad smarter than first meets the eye...
