Olympus WS-310M Voice Recorder

Olympus created one of the world’s lightest voice recorders in its line of WS-3xx devices. I became interested in this model because of its size and weight. The WS-310M packs in 512MB of memory for over 138 hours of voice recording (on low quality mode). At less than 2 ounces including battery, this recorder has replaced pen and paper for recording my adventures out on the trail where lightweight is king.
I initially tested my device by recording about 40 tracks from old analog voice recorder tapes that I’ve made over the past 10 years. The device is straightforward to use. After recording, I snapped off the battery case and plugged the recorder directly into my USB port - no cables required. Copying everything to my computer was easy, but here is where I found the first glitch. The device had a few tracks that got “stuck”. My computer reads the files as corrupt disabling me from moving them to my computer. I unplugged the device and listened from the tiny on-board speaker… no problems on the playback end of things. So that problem has me stumped. I read that cutting power to the device while recording can cause problems, but I can assure you that I didn’t do this. Since this one incident I started using another “folder” on the recorder (there are 5) and have had no problems so far.
I put the device back together after transferring the WMA files onto the computer. Another glitch. The device totally lost the time/date. This is annoying because it tags your files with the time/date. I would imagine that this could be fairly important for most people. I have continually found that this device cannot hold the clock for a long period of time of after mucking with it at all in the USB port. Basically, check your time/date every day that you use this device. Maybe others don’t have this problem?
The device has mic holes in the front and back and on both sides (stereo). I found this very frustrating because it is impossible to twist the device to avoid the wind noise when outside. You have to use it in a windless environment or on a calm day. Bad for outdoor use.
I am pleased with the device, however, I think mine may have a few annoying glitches (corrupt memory, time/date problem). If these problems were fixed, I would give this device a 4 out of 5. With these problems, it gets a 2 out of 5 for total unreliability.

This past week I visited Pilot Mountain State Park in the hopes of making a longer, more secluded hike. I decided to try out an improvised 4-trail loop at a distance of 7 miles or more. I started at the visitor’s center near the entrance and headed off down the Grassy Ridge Trail (1.5 miles, moderate). This trail was basically an SUV road and provided enough level ground and width for riding a horse. I found this trail lazy and slow. I then connected to the bottom side of the Mountain Trail (2.5 miles, strenuous) at the parking lot on S.R. 2061. I would not call this trail strenuous, but it is a long walk on a much narrower trail. This trail terminated at the Ledge Spring Trail (2.0 miles, strenuous). About 1/10th of a mile down this trail the Grindstone Trail (2.0 miles, moderate) splits off toward the camping area. I liked this trail once the gravel walkway ended. It was an easy walk to the middle of the campgrounds. From there I road-walked back to the visitors center (maybe a mile or less) on a mostly downhill grade. The entire loop took just over 2 hours to complete at a moderate pace. A storm had just soaked the forest on the previous day, so hiking up much of the trail felt like splashing up a stream. There are few, if any, water runoff formations on the trail, so the water flows straight down 50% of the trail. Consider that before you go after a rainstorm. (I must be spoiled from the Appalachian Trail) I am going to write the park and suggest that they make a small connector trail from the campground terminus of the Grindstone Trail to the visitor center. I think a lot of people would use this trail in the same loop I made if they constructed it. I am pleased that I now have a pleasant 7-mile loop so close to home. I would recommend trying this hike out some time.
