I'm having this problem that my Seagate external hard drive suddenly turned to read-only this morning when I connected it to Mac. I could only read and view saved data on the drive. But get no access to use the data on my external hard drive. If you have any clues to get permissions to access the read-only external hard drive on Mac, please.

Hello all, I'm fairly new to the Mac world, so please go easy on me. I've been having trouble with an external hard drive I've been sharing between a PC and Mac. I bought a 1TB Western Digital external hard drive a while back and I partitioned the drive into 2 portions - one that was formatted NTFS and one that was formatted Mac OS Extended (Journaled). I have MacDrive on my PC, which runs Windows 7, so I can read/write on both formats. The problem arose when a few days ago I found I couldn't write to the Mac formatted portion of the hard drive from my Mac Book Pro.
I can still access and write to both portions when I use my PC, so I figure it's something that happened or changed on the Mac. I've searched around a little for help on this problem, but the majority of answers seem to be with changing the permission on the hard drive. The thing is, when I use 'Get Info' on the Mac formatted portion, I can't change the permissions (they're all greyed out and unclickable). I'm stumped as I've exhausted my knowledge of the workings of the Mac machine. Is there anything I can do to fix this? For reference, my Mac Book Pro is running Mac OS X 10.5.8. Open Terminal & paste this in, spaces are important.
Chown root / Volumes/ chmod 1777 /Volumes/ then right after the last / of each line, carefully type the name of that external volume, & if it has spaces in it enclose the name in quote marks. See this User Tip by Niel: I accidentally set a disk's permissions to No Access. If the disk in question is your Mac OS X startup disk and your computer stops starting up at the blue screen, restart with the Command and S keys held down, and enter the following commands: mount -uw / chown root / chmod 1775 / exit.
