After installing the 10.5.6 upgrade this morning, my external drive (2 partitions) failed to mount. (Thread here.) Eventually I got both to mount, although now they are both read only. So, how can make them writable? I've tried Sharing & Permissions in Get Info, but obviously cannot change anything there. I'm currently copying all my storage data onto a couple of smaller hard drives because I might just reformat them, then copy at the files back, but in the mean time I'd like to know how I go about making them writable. Cheers.
