I have winxp pro on a ide drive, computer was crashing a lot and going slow so I reinstalled and formatted c:. Also present are two SATA drives on a pci contoller card, that I use for data storage. When rebooting the new install, the sata drives were not there in my computer or in disk management. I reinstalled the card drivers and they are now present but with no letter mapped as if they were newly installed drives. I followed disk managements prompts and made them dynamic and gave them their drive letters. They now appear in my computer but will not open behaving as unformatted drives. Disk management also says the are empty which they most definitly are not. I don't want to format them as they have home movies and photos which I have not backed up. I don't want to use data recovery software as it is expensive and anyway the disk are not damaged in any way. It seems windows has lost its way to opening instuctions on them. Help!
