So did I. I'm glad you have a working solution but there is still something wrong. Not only is your text above correct but it shouldn't take 13 hours to do an integrity check on a 13 Gig database with simple indexes. I'm still suspecting some kind of hardware problem. I'll be interested to know what happens if you ATTACH your copy of the input database, on the other disk, rather than the original. Does it still take a very long time ? Hmm. What OS are you using again ? Oh, you used iostat. Linux. So not the Windows pre-read caching bug. Okay. Simon.
