Hi Noel. Thanks for your extensive answer. Somewhere i in my post i mentioned XP SP3, meaning Windows XP (professional) Service pack 3. I also have (and had succesfully) BIAB installed on a Firewire 400 bus, Western Digital MyBook2, external drive. It worked befor that way perfectly. Control panel; UAC, i only have User Accounts there, no UA-Control function. My install are always done as Administrator & the privileges thereoff. I'll check the administrator privilleges on the external drive, Folder options are set to "use simple file sharing"; alas - switching on Network permissions in sharing did not help either .. PS indexing is switched off, as is System restore ...... -F
