Help I've lost my drives in Windows Explorer

In WindowsXP this sometimes happens with burning program uninstallers, you will see the YELLOW exclamation mark in the Device Manager and now drive letters in Explore

First check to see if the drives have power, then see if the BIOS can see the drives. If YES to both these then download this and after a restart all will be clear !!!

Then reset the DMA for these drives using this tool visual basic tool if you are using a new HDD typical UDMA is 66, you may not need to do this last step check first but it will cause you no harm if you do it anyway!
