Dropped frames are almost always caused by insufficient drive speed.
In your case you are playing back from a drive and capturing to a drive, so you'll need to check both.
When you playback watch the front of the Hyperdeck shuttle. If you see a blinking red light, that means the drive on the Hyperdeck is dropping frames. If this is not the case, then your hyperdeck is doing what it is supposed to do.
So for dropping frames on capture there are a few things to consider. Codec is the largest consideration. If you are using Uncompressed, your hard drive will need to sustain 156.5 MB/second of data throughput (minimum). You can check this by running the disk speed test utility that we provide with our Desktop Video Products. Cross reference the matrix and it will clearly tell you if you have enough drive throughput.
If it turns out you do not have enough throughput there are a couple of different ways to handle it. First you could use a compressed codec. That requires much less. Or you can install a hard drive array which should increase the throughput available to that drive.
So those are some low-hanging fruits to check.
