Hi, if you remember, I had troubles with one Mammoth2 drive some time ago. At now, I think I can say that difficulties have been solved by firmware upgrade (in my opipion v03a was the first usable firmware for M2) - I can not repeat FreeBSD freezes any more, because medium errors disappeared... However I have one question/micro-announce: Does anybody know about any "more mature" tool such as "camcontrol modepage ...", which can communicate with SCSI devices and write out data from them in a human readable format? Just for FreeBSD of course (I know about M2 monitor for Windows.) camcontrol does know mode sense command only (log sense would be great), numbers are only up to 4 bytes and so on and I'm not sure if it is desirable to extend libcam further, because it is in a base system. I have written very small and simple perl wrapper around camcontrol to get some interesting information from Mammoth2 drive: Number of read/write errors, hardware compression information (! great thing !), drive usage statistics and an environmental temperature. EZ17 is the next on the plate...
