My Mac OSX does not recognize NTFS partition. By default, I know it should at least be on read-only mode but under Finder I see the drive not even being mounted. I went to Disk Utility to see the NTFS partition, the one I installed my Windows 7 on, but it says the format is in MS-DOS(FAT) whereas I clearly see it shows as NTFS on Windows 7. There are about two files sized as 8.50GB stored on that drive so that should prove it's not clearly formatted in FAT system. I try to verify the disk and it fails as follows: Verifying volume “disk0s3” ** /dev/disk0s3 Invalid BS_jmpBoot in boot block: fcfcfc Error: This disk needs to be repaired. Click Repair Disk. The partition has Windows 7 installed as well as a lot of important data and I do not want to jeopardize it by choosing the option "Repair Disk" that I'm not even clearly sure of what it would do to the drive. I'm using MacBook Pro i7 15" and if anyone could help it would be great.
