Each person is going to vary, but the really short times make me suspect
not fully charging the batteries, or the batteries are not capable of
holding a full charge. At least that's the first thing to investigate.

The details are recorded on the disk, it's part of the MD format. HHb
just reads the details off the disk when asked. There is no reason for
them to keep other than current track data in memory.
I suppose it might be useful to download the disk catalog, but getting
into the habit of keeping a field log will do more than trying to
remember it later or stir around with such incomplete data. I label each
disk with a disk number in the portadisc, but other than the track
numbers don't need any other info out of the portadisc when I get home.
It's all on my field cards. Well, except the track length, which I don't
put on the card until I've decided how much of the track will be
archived. Often I remove useless parts before archiving. Why store the
long section of truck noise before you gave up, or whatever?
I do enter my field log data into a database. That field log contains a
whole lot more than the data on the MD. GPS readings, for instance. A
list of the species found and their abundance. Information on the mic
used. And so on.
I do hope everyone who thinks their recordings have scientific value is
using a GPS to get the locations. Without accurate location the
scientific value of a recording drops considerably.
