I noticed that my current disk drivers are deprecated - use I20... I ran across a note a FAQ and a HOWTO on installing i20 disk driver support. I think I have a compatible SCSI adapter and disks. I guess the big questions are: 1) will I get any benefit from using i20 (i.e., faster, safer, more disk fail info, etc.) 2) will I risk screwing up my current disk data? 3) does smartd info work through i20 ? Thanks for any info Bob Gustafson
