hi ya donald

since the $1700 EFR240 is raid1 ( mirroring )...
and only for 40Gb ??? geez...

- just buy 2 40Gb disks at $130 each and use 
  dd/cpio/mirror.pl etc to mirror one 40Gb to the other disk
  and you'd have exactly the same function 

since its supposed to be raid1...
you should be able to remove the ONE faulty disk
and plug it back in and it should recover itself...
	-
	- if it does NOT recover... its NOT "raid"
	-

- might have to remove each of the 4(?) disks to see which
  one is the bad one...

- you might want ot take all 4 disks... and hook it up
  to a PC with hw raid controller and see if it can
  see the ext2 partitions...
	- remember the disk id ( master/slave,  scsixx etc )

- linksys might be able to take the 4 disks and plugg it
  into a different working box and pull data off for you ??
	( if there's nothing wrong with the disks.. )

lesson(?):
using raid does NOT eliminate backups... backup is still needed
