Author Topic: Servers won't recognize DCP drive Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 08-06-2016 03:13 PM                        A related question: can Macs read a drive formatted with an MBR partition table and an ext2 or ext3 content partition without add-on software? Thanks in advance.  |  IP: Logged Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 08-06-2016 03:40 PM                     Leo, rather surprisingly since Mac OSX is Linux-based, no they cannot. I have a Linux virtual machine on one of my laptops and can read them on that, and copy files to or from a shared folder. Unfortunately, the version of Linux which I have cannot format a disk as Ext 2 or 3, only as Ext 4, so I have to format on another machine, but can then read and write them on the laptop.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-06-2016 04:39 PM                     Only with the free OSXFuse/ext2 driver or Paragon extfs, but not natively. Actually OSX is not Linux based - Linux didn't even exist when NeXTStep was forked from BSD and was later transformed into Openstep, Darwin, Rhapsody and OSX. Still I consider it very strange that Apple never built-in native ext support. OSXFuse/fuse-ext2 allows to format ext-volumes (MBR or GUID) through the standard OS X disk utility dialog. However, as most modern implementations, it will create partitions with inode sizes of 256, not 128 as mandated by ISDCF. They will still work with most servers, but may cause ingest problems on windows based TMS systems (because some of them may use outdated ext-drivers that only support inode size=128). - Carsten  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 08-06-2016 07:39 PM                        Thanks folks. The reason I ask is that I'm making some DCPs for a forthcoming show, and providing copies to the programming partner we're working with at the end of it. As she's a Mac user and I've never owned one, I didn't know if she'd be able to read the content on a DCP drive formatted per ISDCF. As I now know that the answer is no, I'll format it NTFS (which the DSS200 can read), which I know that MacOS can read natively (though not write). The way I create inode 128 partitions is by "mke2fs -t extX -I 128 -L DiskLabel /dev/sdXY" within a Linux terminal window - it's always worked for me.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-07-2016 09:12 AM                     While I would never advise to ignore the ISDCF hard disk recommendations for mass duplication/distribution, coming from a windows based DCP creation tool, NTFS is the safest way into a DCI ingest process as a matter of fact, across all servers and TMS's. It's useless to setup a VM, install ext drivers, format ext drives etc. if you simply want to transport 'your own' DCPs to a DCI system. As long as ext2/3 is not supported natively in windows, it creates too many possible problems in real life. If you create/store your DCPs in a Linux environment, using ext2/3 is a no-brainer. - Carsten  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 08-07-2016 12:43 PM                     quote: Carsten Kurz Tuxera is the most solid and also fastest in my opinion. It actually comes for free when you buy certain Toshiba external 2.5" USB drives. Lol! Unfortunately, I found this out the hard way. I had two or 3 brand new, spare, Toshiba drives sitting here that I had bought when they were on sale for future use in case I needed them. I didn't realize they came with a free, fully authorized version of the "Tuxera For Mac" program on them until a couple of weeks after I had bought the 'paid' version online when I unboxed one of the drives to use it for a project. D'oh! Oh well; "ya win some & you lose some..."  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 08-07-2016 04:09 PM                        quote: Carsten Kurz coming from a windows based DCP creation tool... [...] If you create/store your DCPs in a Linux environment, using ext2/3 is a no-brainer. In this case, I create my DCPs in a Linux environment, but need to provide copies to someone who uses a Mac for long-term storage. Therefore, I'm thinking that NTFS is the best best, because the Linux-based OS I use (Ubuntu) is able to write to it, and MacOS is able to read it, and most DCP servers out there can read it as well. My other option would be to go the HFS+ route (using the hfsprogs add-on for Ubuntu), but my impression is that fewer DCP servers can read HFS+ than can read NTFS. Of the two models of server I have significant experience using, one (Dolby DSS200) can read GPT/HFS+, but the other (Doremi DCP2000) cannot.  |  IP: Logged
