I could be wrong but I believe OS X can read files from an NTFS formatted hard drive. In fact, I know for a fact that OS X can see the files. Wether or not Pro Tools can retreive Session files from the drive is another question but I'm thinking that it is likely. As long as you're importing the files to the local drive while you work, I think it should be ok.

Edit:

After a bit of searching, apparently ntfs is rendered read only in OS X. I don't know that this is any different in Leopard.

This program apparently allows you to both read and write to ntfs.

If something is read only, you simply have to make a new, local copy after you read it in. Sort of going backwards, but do what you have to do.

Sure but if you need to take that session home again you need to be able to write back to the disk. Unless you want to be burning DVD's every night.

Thanks so much, that Mediafour looks like the best option so far, I appreciate the help!

Foramt the drive FAT32, Protools works after V7 on both PC and Mac.

Do not use NTFS, its already been noted.

MediaFour Macdrive is probbly your beat option, then you can keep the drive Mac formatted for work reasons.

yeah format fat32 (its called ms dos format if you do it under the mac disk utility), this allows for both mac and pc access to read and write, although it is a little slower and less efficient than ntfs, so don't record directly onto the ext hd, just copy paste the project after you record it on the daw.

google has a free utility that will allow Macs to read/write NTFS.
