Unable to Merge Partitions on XP SP3-Error 1609

I'm using an HP DC7900CMT with Windows XP Sp3, I've got an HP recovery partition on a logical D drive partition. I am able to delete the partition, reformat it and marge it in the GUI, Upon clicking apply and reboot, it appears to go through it's processes and progresses to 100% and then comes up with Error 1609 while executing Batch,  then it says Error 1609  Lost Cluster- Lost Clusters 3933912. Any help would be appreciated.
