Onecare is trying to Defrag a Backup Partition for a Compact Pesario, the D Drive partition is a FAT32 partition and Onecare will not defrag that partition, I think there should of been a way to tell onecare to skip this partition in the settings, if not this could lead to a complete Harddrive Crash, and is a very risky thing to do while running Windows XP from a NT Partition.
