Hi all, Is there any software that can check if a NTFS hard drive is working properly and repair it if necessary? I tried programs like Disk Warrior, TechTool Pro and Drive Genius. All seem to be good programs but none of them support NTFS even though my MBP can read/write NTFS. I would format my external hard drives to mac format but I need those drives to be accessible on a PC as well. Suggestions?
