the firmware is the one I dl from the 3ware page 1 week ago, when I
installed the system, the kernel is 2.4.19, so I guess that shit fit.

yeah, mostly true, tho I need that for an ftp server, its unconvinient
to guess how big a dir will get an "waste" a partition on it when the
space wont be available to other dirs.

Anyhow, I know now, I shall never enable the write cache again, i kinda
pi.. me off to waste performance..well security goes first. Since its an
ftp server speed is not all that important - the line aint THAT fast.

Anyone know where to get those tools to disable write cache on my IDE
hds ? I hope I dont need windows for that...

thx again
