Partition Magic can not merge

I have a c and d drive and would like to merge the 2. I have ran partition magic to merge the 2 partitions and get a 100% done with an error message that reads:

 

Error 1609 while executing batch

Error 1609: lost clusters, clusters 434773 - 434773

 

Checking on how to fix I need to run windows xp cd boot in recovery mode. The problem is I do not have a xp cd.

 

Any other way to fix this, or can I just delete 434773 cluster. If so how?

 

Thanks,

Michael
