Question: are there any networked drives, or external HDD's involved in the I/O sub-system? Those can cause the Media Offline, depending on a few factors. If not, then something else is causing the loss of the links to the Assets.
Thanks for the reply.
Can you please explain to me what you mean by I/O sub system?
Right now, all my media are being stored on an external hard drive in Raid 5 configuration via eSata connection.
Sometimes, I would back up my project file on another hard drive, just to be safe. Can this be causing the media to go offline? The thing is, when I close and re-open the project file, different clips will go offline, so it's not consistent. There doesn't seem to be any logical reason.
The I/O sub-system = all of your HDD's, internal and external.
The eSATA externals should not have the same issue, that one usually gets with USB, where each time the system is booted, a different drive letter can be assigned by the OS, depending on the order that mass storage devices are turned on, plugged-in or recognized. Since the links to Assets are absolute Paths in the PRPROJ file, if they reside on an external, that was recognized as say J:\, when they were Imported, but later, the OS assigns that same external, say H:\, the links no longer work. I could well be wrong here, but I do not think that the drive letter assignment for eSATA is as random, as it is with USB.
Also, at least on Windows, one can establish a permanent drive letter assignment for each external, so that it is always seen as the same drive letter. This is done at the OS level. I assume that the Mac OS has similar capabilities. I have every external set to a permanent drive letter, and in the OS of each of my computers, so that drive Z:\ is always seen as Z:\ and in each OS.
Maybe others can comment on the drive letter assignments for eSATA and specifically on the Mac OS.
