I guess I did it the wrong way... I upgraded the array on two of my web servers (W2003 SE, SP1) and copied the whole web-sites (wwwroot, etc) directory to the new drive. To do this, I copied everything once (a lot of files on our site that get ftp'd) and once I had copied everything, stopped everything (disabled), did a last update and renamed the drives in case anything was hard coded. Two reboots later, I have the new array as F: and the old as E: (what I wanted). Brougt everything back on line and all sites were up, happy and no errors. 29 hours later (Application pool recycle time), I start getting ""W3SVC 1009 with "exit code was '0x80'" errors and the final W3SVC 1002 with exit code "Application pool 'XXX' is being automatically disabled due to a series of failures in the process(es) serving..."
Help - I have done all of the right assignments again (.Net, IWUSR, etc.) and this two boxes continue with the weird random stops
