Yeah I agree they are difficult to deal with sometimes. And expensive. I agree the restriction should only apply to the place where I install the application. I told them that two years ago and they said that's the way their software is designed, to prevent installation if RAID 1 is detected, that's what the tech support guy told me anyway. They want to prevent someone from taking a mirrored drive and giving it to someone else to use on a different machine. They told me this two years ago not sure if they have the same policy though - but my version is about two years old. I could clone just my data somehow on a seperate drive or backup (not the applications and OS), yet I also want to clone the entire OS and applications that's where most of the time goes into as far as restoring a disk or buying a new disk is concerned. I'm paranoid because I've had 3 crashes in the past 4 years and it's always a pain delays my work for days. SATA drives are made cheap compared to server grade SCSI's. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008
