Something happened to my secondary and third IDE hard drives. In WinXP i cannot acces data from them and when i click on them it tells me to format. I have a lot of data in them and don't want to lose it. When i tryed chkdsk it won't let me. When i tryed tools like parition magic it says the disk was unmounted imporperly, but didn't fix it. I tryed to remap the letters but that didn't work too. What can i do to fix this problem?
