Graham is the king! Despite loosing out to Rupert in yesterday's Googlefight he got to the bottom of a thing that has bothered me and others for ages. If you have a striped array hooked to NT / 2k /WinXP and then you remove it Windows keeps a "ghost" record of the array and if you attempt to attach another array with the same name you get told where to go - once that has happened it seems that the disk manager gets less and less willing to see new SCSI devices. However, as ever there is a registry key that returns things to disk nirvana if you delete it!
