Major Quicktime Issue! Help!
Recently I’ve noticed a relatively high number of corrupted video files on our database, but as some of these files are old and have come from different sources i assumed that they had always been like that.
I was just watching a file off of the drobo (raid) and then I imported the file into premiere for mac (don’t ask, not my decision) and it said it was offline almost straight away. i went back to open the original file and all of a sudden it’s corrupted. i didn’t change any settings or save the file in anyway, so i’m absolutely baffled. it still opens in VLC but not in quicktime, and MPEG streamclip claims it can’t find the audio or video tracks. I’m assuming whatever happened here is the same as what’s happened to all our other corrupted files.
the file is a PAL DV quicktime opened with quicktime 7.6.4
any help would be massively appreciated,
thanks

Corruption is something that normally happens to individual files and if VLC and is able to read the clips, this smells even less to corrupted files.
I would start with a bit of maintenance: Repairing Permissions and rebuilding directories (DiskWarrior).

thanks for replying so quickly
is there a free way of doing this? it looks like disk warrior does whole drives, i just want to recover one file for now, messing with the whole drive directory seems a bit scary with 12TB
thanks

Disk Warrior is a must have application, it is $99 or something like that. But Disk Warrior works on the structure of the drive and not the files, but it is the first line of recovery. If the disc directory goes wacky it can lead to other problems but it doesn’t recover files. There is Data Rescue app for that. No free lunch free but these are all relatedly cheap programs and they all do a certain amount of maintenance to help prevent file corruption.
Have you tried to copy the files to another drive and see if they work?

The directory is what tells the OS where everything is located, so having that “right” is very important. If you decide to use Disk Warrior, run it first, then Repair Permissions. DW will allow you to cancel before it writes the new directory to the drive. I use DW at least once a month as maintenance on all my active drives.
