why drops??

[corrientearriba]

I've been having problems with some drops. Im wondering why exactly does this happen, as the only info I get is a number indicating the problem. For example (drop 48, in a red color).
Could this be a problem regarding the cable that connects the drive with the camera?
Could it be a problem with the drive itself?

I havent had the operator doing strong movements with the camera, no bumps against anything either.

Thanks for the help....

could be the cable, try another if you have one. could be the drive, you should try another.

Any low-frequency noise or vibrations where you're shooting?

Motion can be a problem, even when you don't think the operator is doing much. Often times, it's not so much a strong or fast motion as much as it is the direction of motion in contrast to the rotational plane of the drive platters.

Have you tried reformatting your drive. This helped to solve the same issue for me the only time I experienced it.

Formatting the drive may help. Also you should email the camera log files to RED if you have not. They may be able to identify a problem by reviewing them.

I noticed a few on my most recent shoot- using RED Drives (the original models)... I also noticed my AC unplugged the drives while the cam was still running, several times, to swap drives.

Now, I don't know if this caused the issue, but in my case we were doing locked down tripod setups- not even panning. So, I'm thinking, I need to tell her to not ever do that again...

Unplugging the drives while the camera is running is just fine. But you have to be sure to un-mount the media before doing so. Press Undo+Exit will unmount or you can do so from the menu and program the unmount to a user key.

Even when tripod mounted, drops can be caused by vibrations, especially low-frequency vibrations. Depends on what you are shooting. Best thing to do is see if you can identify a physical cause at the shoot location. If it happens with more than one drive, then it's probably an external force such as vibrations. Or possibly a bad drive cable, power issue, possibly a camera issue. If it's just one drive acting up, then format and test the drive. It may need to be sent to RED for evaluation and repair.
