A more computer-knowledgeable person in my department purchased some 300 GB external Seagate hard drives for several of our chromatography units, especially those with 21CFR11. Unfortunately, with the requirement to sign on, this cannot be scheduled automatically in down times. I have been beginning new Databases every 650 MB (check the systems first of each month), archiving the old ones on the hard drive, and backing up that Databse onto CD as a "non-official" backup (FDA apparently discourages backup Databases). We will do a networked system someday. Our IT department doesn't yet understand that our equipment is not on the network, and that confuses them, their "out".
