Based on this information "incorrect pageid (expected 1:3280; actual 0:0)" the page is empty (filled with zeroes). It could be file system corruption or failed sector on the drive. In our data recovery company we have this situation pretty often. Clients bringing corrupted SQL files where part of the file is empty or filled with information from other files. If you don't have backup there is possibility to scavenge the original drive and find lost pages.

Open the mdf file in any hex viewer (e.x. WinHex) and go to offset 19A0000 and check the page for the data. It could be just page header corruption but more likely whole page will be empty. Then you can try to search the page by the page header on the disk and copy it to the file.

Or send the drive to data recovery company 🙂
