Situation - Server: SBS 2003 R2 SP1 Premium - Full install without ISA. All updates and patches installed Workstation: Windows Vista Ultimate 64 (patched for SBS) on a Nvidia 590SLI/AMD motherboard. OS and user folders areon a Raid 1 array butthe "My Music" folder wasredirected via shortcut toa Raid 5 array. Both arrays are SATA. I set SBS to use home folder redirection to a file server and then logged off the Vista Workstation and then back on. While logging on the server initated the copy normally and transferred all of "My Documents" including the"My Music" files via the shortcut,to the file server.The music files were not readable but when I copied a couple of the back they worked fine. I then changed SBS to not use home folder redirection and logged off and back on the Vista workstation. The file copy transferred the files back to the workstation and put them all on the Raid 1 array. Fortunately there was160gb available and they all fit.I checked them and they were not fully accessible. Assuming that the copy had not completed fully, I left the system running overnight and then checked them again in the morning.The files were still not accesible and no longer existed on the server. They appeared to exist on the workstation but could not be opened. I could not access any of my files irregardless of the file type. Even .txt files were not available. I rebooted the system and the hardware could not find a bootable device. I booted back into repair mode with a repair disk and the system couldn't find anything to repair. I booted into DOS and found the files that I had transfered appeard to have overwritten or corrupted drive's boot partitiion (nvidia raid). This was the first reboot since performing the above changes. I first suspected that the Nvidia Raiddrivers were overwritten and not the OS but when I tried to rebuild the array at the BIOS level it failed to rebuild. This is just a test workstation and server so I'm not sweating the rebuild but I would have freaked if this happened in realtime. Steve
