If you can read data from a qvd file, then it is not corrupted.
Below code may help you.

Set ErrorMode = 0;

CheckQVD:
Load * From Qvdname.qvd (qvd);

Let vNoOfRows = NoofRows('CheckQVD');
If Len($(vNoOfRows) )>0 then
Trace QVD is not corrupt;
Else
Trace QVD is corrupt;

Try to load the qvd in a new Qlikview document. If it works without errors then the qvd is not corrupt.

If you load that QVD, You can understand whether the file is corrupted or not {I Mean to say, If you are not getting any error - That means QVD file is good}
