Hi, I'm following the 24 step guide provided by Microsoft explaining how to fix corruption problems in your SS DB but I have a problem fairly early on. I've created a physical.txt file which seems to map the names of the files I book in to the names SS uses. When anaylize produces an error, I try to look up the SS file name but it does not exist. Here's an example - The CRC for data file '' (vbdbaaaa.a) does not match the stored CRC. The file may be corrupt. There are over 9000 lines in my Physical.txt (seems OK) but the string "VBDBAAAA" does not exist in upper or lower case. How do I find which file it is talking about? Thanks. Peter.
