    No media can be written to any mounted drive.

    I'm having a lot of problems with my two Avid licenses (Media Composer 7 and Symphony 6.5). My Symphony system doesn't recognize any external drives as media drives. Only the four internal drives (inside the Mac pro) are listed in Media Tool.

    I noticed the problem when I tried to edit something on a new Symphony 6.5 installation. It didn't recognize the external Mini-SAS Disk Array. So I decided to try a firewire drive and a usb drive. I made sure all Permisions were set to Read & Write, but this didn't fix the problem. I then move the USB and the firewire drives to the Macbook Pro running Media Composer 7 and only the USB drive is recognized as a media drive. If I unmount the USB drive and leave the firewire drive, I get a message saying "No media can be written to any mounted drive.  Please check write permissions". Like I said all permissions are set to "Read and Write".

    I'm getting frustrated and feel like opening Premiere Pro CC and start editing, but I need to get this problem fixed since I spent a lot of money on Avid licenses (full and upgrades).

    How are those external drives formatted?  Are they HFS+ or something else?

    Must think of something clever to go here...

    hbrock:

    Format is as follows:

    G-Tech G Speed eS Pro is formatted Mac OS Extended

    LaCie Rugged is formatted ExFat

    G-Tech G Drive Mini is formatted Mac OS Estended (Jornaled)

    The internal SATA drives that Symphony (Mac Pro) recognizes are all formatted Mac OS Extended (Jornaled) except for one that is formatted Windows NT Filesystem (for bootcamp), and even this one can be used as a Media Drive with no issues. Go figure...

    Note: The LaCie has no problems when connected to the Macbook Pro running Media Composer 7 on Mac OS X 10.8.4

    Re: No media can be written to any mounted drive.

    It would be a bit easier if you indicated what connections existed on each drive along with their formatting. You also didn't state which OSX version you are running on the affected machine.  Details are helpful.

    The G-Tech eS Pro requires their RAID card.  Don't use any Avid supplied RAID software.  If it mounts as a R/W drive in the Finder it should work with Avid.

    ExFat support in OSX has been a moving target due to incompatible block sizes between Windows and Macs.  Not sure about whether Avid supports ExFat or not.

    Windows NTFS can be read but not written by OSX.  To be able to write NTFS you need Paragon or another software solution.  Due to the additional overhead, drive performance may suffer compared to supported native formats.

    It is recognized a Media Drive by the Symphony via USB 2.0

    G-Technology G-Speed eS Pro (format: Mac OS Extended)

    Connection: Mini SAS > Not recognized as Media Drive 

    Note: This computer has 4 internal WD SATA drives with six partitions in total, all of them are recognized as Media Drives by the Symphony; except for the OS partitions of course. The ExFat formatted LaCie SSD is the most compatible of all. I use Paragon to write to the NTFS formatted drive and it works great as a Media Drive. For the G-Speed, I use the supplied ATTO R680 raid controller. It was formatted and configured for raid 0 at the factory and it works great with Adobe Premiere Pro in the same system.

    Re: No media can be written to any mounted drive.

    Don't know if it will help anything, but try opening the console (under tools) and type "alldrives". I use it to let avid see shared folders as media drives, and that might just be the way your raid's software virtualizes harddisks. And just for the sake of it (I'm sure you already tried) under settings>media creation>tab drive filtering and indexing > if there is a notch in "filter network drives based on resolution" turn it off. Good luck

    The console command did not help. I tried both, "alldrives" and "alldrives 1" (I wonder what is the difference between these two) and even though it says "All drives will be viewed as media drives", when I go to media creation, it does not show the drives with the issue, not even "grayed out". Everything under Drive Filtering & Indexing is unchecked.

    Re: No media can be written to any mounted drive.

    After many tests and clean installations, I narrowed down the problem to the 2 G-technology drives (one firewire and one mini-SAS Raid). I remembered that I never formatted these drives, since they came preformatted for Mac and ready to use out of the box. So, I decided to re-format the smaller of the two first, since it was easier to backup. That fixed the issue and both, Media Composer and Symphony finally recognized the drive. Now it was time for  the G-Speed es Pro. I went ahead and created a new folder to keep all my other folders organized in one place, ready for the backup. Much to my surprise, I didn't have to re-format the drive, it was recognized immediately by MC and Symphony. To me, it is still a mystery why a simple re-organization of my files seems to have solved the problem. Go figure...

    Just want to thank you all for your suggestions!

    Re: No media can be written to any mounted drive.

    I had the exact same issue with a G-Tech 4 Tb Thunderbolt drive connected to a pre-qualified 15" MacBook Pro Retina running Media Composer 7.0.3, right down to the BootCamp partition being available.  I followed all the steps in this thread to no avail.

    So I thought and thought and thought some more . . .

    Then I created tone media and imported a test pattern to the MacHD.  Then I shut down Media Composer.  Then I copied the Avid Media Files folder from the MacHD to the G-Tech drive.  Then I restarted Media Composer.  BOOM:  the drive showed up and has been there since.

    The only anomaly now is the capture resolution is stuck at J2k, while everything else is set to DNXHD 145 in my 10880i/5994 project.  I'll very likely NOT capture from tape to this laptop.  Even if I did I could always transcode if necessary.  Curious though that J2k is the only resolution that shows up in Capture.

    Offering this to anyone out there who found themselves in the same situation.

     

    Cheers,
