This event appeared in my System log after I cloned a partition to another area on my laptop's hard drive with Paragon Hard Disk Manager. I cloned “F:” to a temporary partition, deleted and recreated “F:”, and moved the files back to the new “F:”, as the MFT on the original “F:” took up 50% of the partition. Normally I would have created a new SID for the temporary partition, but I planned on deleting it immediately after moving the files back to “F:”. I found this event message two days after doing the partition maintenance, and I was not aware of any problems occurring because of the duplicate ID. I did not reboot the laptop during the process, and I suppose a problem might have occurred if I had done so with two partitions with duplicate IDs.
