I have an external HDD that is formatted for the Mac (FAT) but when I plug it into my PC it does not read it - how can I fix this without reformatting to to NTFS and losing all me data?!
Don't wish to be contrary - but would you check that drive format with Disk Utility again? FAT32, if it is that, should work with both Mac and Win.
If reformatting is necessary, try networking your two computers so that you can transfer data from the ext HD, connected to the Win computer, that way.
