Solve : External Drive format problem (Mac and Win)?

1.	Solve : External Drive format problem (Mac and Win)?
Answer» Drive A – Seagate 2TB (current format FAT32) Drive B – WD my passport 071A (current format GPT) Here is the issue. I have two external DISKS, drive A and B, used for BACKUP and storage primarily. They are in quite good condition and have not been dropped, hit, etc. to my knowledge. I recently TRIED to use them and both would not appear on my computer (running WinXP). I opened disk manager on XP and Drive B appeared but nothing registered and it looked BLANK (although it said it was a healthy GPT protected drive). Drive A had nothing. I then plugged them into a Mac and using Disk utility both appeared (but could not open the FILES on either, otherwise the Mac would just crash). When trying to reformat (that’s all I could do at this point) drive A came up as: error: resource busy. Drive B – error: could not unmount disk. Please let me know if I need to put any more information, and if the issue can be solved. How do they show up in Disk Management in Windows ? ?
