Hi,
First, thank you so much to the developers of this software, and to those who maintain and contribute to these forums!
My question relates to how to best format the drive for delivering my DCP, using a Mac running Mavericks, in order for it to be DCI compliant and be read as widely as possible.
I made a DCP from TIFF files generated in Rec.709 by After Effects CS5 these last days and I've seen a difference between the J2C files created by opendcpj2k and other J2C files made from TIFF files in 'DCDM XYZ Adobe 5900K gamma 2.6' and converted by opendcpj2k with the '-x' option (to prevent from a double color space correction). Authoring Software - I found OpenDCP overly complex and was pleasantly surprised by DCP-o-Matic. The Author is really helpful and the Software produced a (SMPTE) standard compliant 2K/4K DCP. DCP-O-Matic is really foolproof since you just throw your Quicktime and discrete audio tracks on it and it does the rest.
I have read that the ideal is to format the drive from Linux (which I have no experience with, and would rather not have to enter that whole other world right now). And that using Paragon ExtFS for Mac OS is likely to cause file corruption. Is this still the case?
From what I read (here (https://groups.google.com/forum/#!topic … WY8NApcG6M) and here (https://vimeo.com/69176054 in the comments section), it appears that the drive should:
- be Ext2 or Ext3 formatted
- have a 128KB inode size
- have the DCP to be at the root level of Partition 0
My questions:
1. I have read that Paragon ExtFS for Mac OS is unable to either format 128KB inodes or have the DCP at the root level of Partition 0. Is this still true?

2. Which is better, Ext2 or Ext3?
3. I have also read that Paragon will often cause file corruption when copying files. Is there a way to avoid this?
4. Besides Paragon ExtFS, is there another way to reliably write a drive with the correct format from a Mac?

5. Also, does the type of drive itself matter? That is, does a USB 2.0 work as well as a 3.0 or a FW800 drive? I just purchased a USB 3.0 flash drive, and am hoping this will do.

Many thanks in advance to any advice-givers!
