Soren has made major improvements to the ATA layer, and may in fact address any issues you're having in the past. Is the IDE disk an IBM/Hitachi drive per chance? I've seen this happen on them. It's a known ""feature"", which (from what I understand) was supposed to be removed in later models, but I haven't bothered to check. Also: after upgrading, consider installing ports/sysutils/smartmontools and enabling SMART on the drive/in the BIOS. You may have a drive that's going bad -- IDE isn't known for reliability these days. Hope this helps. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977. | On Thu, Aug 05, 2004 at 06:10:00PM +0000, Bjoern A.
