Deluxe emailed our film programmer to find out a bit more information about the errors, so it may look like they are examining it in more detail. Fingers crossed. I happen to share Terry Gilliam's view of technology as depicted in his 1985 film Brazil. It will only grow in complexity and will continue to randomly fail . But did you try the USB ports on the back of your Doremi server yet? Or are they totally out of reach? If the problem isn't obvious, you should try to isolate the problem by exclusion. quote: Carsten Kurz In my opinion, this is unnecessary hassle going with ext2/3, as Windows and OS X can handle NTFS better. Most cinema servers nowadays can deal with NTFS drives without a problem. I would not suggest NTFS for large scale distribution, but under typical festival conditions, it is the better choice. Well, it will be interesting to see what the future brings. We're not there yet, but the current MBR scheme does not scale beyond 2 TByte. GPT is an obvious solution, but it will introduce new compatibility challenges. EXT2/EXT3 might have been the only viable choice a few years back (it's open source and supports large files), but for the future I would rather go for something that focuses more on data consistency and availability (without the need to run manual FSCKs) like ZFS. But that would obviously introduce new compatibility issues. For the time being, it would be best practice to mount those file systems on those disks in read-only mode. That way it is rather impossible to corrupt the filesystem or cause troubles because of being marked "dirty" after an unclean unmount.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 12-13-2013 07:19 PM                     Marcel, the problem is not with the Doremi server. When we have this problem, none of the USB ports work. Like I said, we also try it on other Doremi servers in the booth with the same results. The server is fine. On many occasions, we had the filmmaker contact Doremi and have Doremi tell them the proper way to format the drive. This ALWAYS fixed the problem.  |  IP: Logged Frank Cox Film God Posts: 2234 From: Melville Saskatchewan Canada Registered: Apr 2011 posted 12-13-2013 08:26 PM                        Since RHEL 7 will be using XFS by default instead of the EXT? filesystem that has been used in all previous RH releases (most recently EXT4), I suspect that a lot of enterprise systems will start using XFS and EXT will begin to slowly disappear. RH carries a lot of weight in the enterprise Linux sector.  |  IP: Logged Steve R Pike Film Handler Posts: 66 From: Gloucestershire, UK Registered: Apr 2011 posted 12-28-2013 10:13 AM                     Hi all, hope you all had a good holiday. I popped into my place today as I saw Philomena sat in the foyer. We have no screenings until Jan 7th as panto is on, but thought 'as I'm here, I'll load it up'. Surprise surprise the drive failed. No content to ingest. This time tried all USB ports, but knew that wouldn't be the problem as the Pearl and Dean advert drive ingested fine using the same USB socket plug and dock. This is about the 4th drive now in recent months that have failed - all if which are Deluxe! I know that as their helpline number is the only one we've called! Getting frustraited with this as their only suggestion is "we'll send another drive". That's all very good and thankfully we still have over a week until it's screening, but I have a horrible feeling that if this continues to happen that it will fail on a film screen in the next day leaving no time for a replacement drive. This digital world, in my mind, is slowly destroying the old age art of projection. :-(  |  IP: Logged Michael Putlack Expert Film Handler Posts: 187 From: Fort Collins, Colorado Registered: Sep 2011 posted 12-28-2013 01:56 PM                        About half of the drives we get from deluxe have an issue being read when we plug it into the ports of our Doremi servers. We have a hard drive "shoe" always plugged into the back USB port of the servers, and when the drive doesn't work in the port it always works while using the shoe. It is annoying because it takes longer to ingest (sometimes an extra hour +!) but it gets the job done.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 12-29-2013 03:59 AM                     Michael, Rebooting the server should fix the problem. Also, make sure you press the grey button before removing the drive. Finally, I've encountered some servers which were quite slow in scanning the content, make sure you wait a minute before giving up - I actually had an nGEST unit which was taking a couple of minutes before finally showing up some content.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Sometimes it is formatting, sometimes it is damage. Heck, some look like they are just plain empty.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 12-29-2013 01:41 PM                        We've never had that issue here yet, thankfully. I was going to make a joke about those "bad quality drives in the UK" but now people are saying it's happening in other countries too, so... maybe it's just drives wearing out from all the use and abuse?  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 12-29-2013 02:32 PM                     Those drives are being shipped around a lot, that could cause some physical damage. But regarding the actual usage, such a drive is probably used a lot less than a regular drive would be. They're only written to if they're fitted with new content and every location that receives the drive will usually only ingest the content just once.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 12-29-2013 10:05 PM                        Right, that's why I said "use AND abuse." Mostly abuse by getting tossed around like footballs by the shipping companies, getting banged around or dropped while being inserted into servers, and so on.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 12-30-2013 12:24 PM                     Yeah, I don't think there are many other industries that use "common household" harddisk for data distribution this way. Although it is quite astonishing what kind of abuse a disk in parked position can actually sustain, they were never really designed for this kind of abuse. If it's just internal mechanical damage that causes many of those failures, that could probably be fixed by switching to SSDs, once they become a bit more economical at the required sizes. Such a move could also potentially dramatically improve the ingestion speed, as long as you're using SATA at 6g or USB 3.0 and not "plain old USB 2.0".  |  IP: Logged
