I’ve been transferring large HD video files from 64Gb micro SD.
However, I have come across an issue that has an impact on the transfer rate and storage capacity.
I’ve just returned from a trip where I transfered video files at the end of the day.
Initially (days 1 & 2 of my trip) the transfer of around 50Gb took 20 - 30 minutes.
However as the trip progressed the transfer time went up to about an hour.
When I got home I anticipated around 350 Gb of data would have been stored but found there was over 900Gb.
When I looked at the data stored, I saw that the device had stored day 1 no problem. On day 2 it stored the new data and created a back up (copy) of day 1.
By day 6 it was creating a 5th back up copy of day 1 in addition to the new data.
Although I’m not entirely sure, I assume this explains why my transfer times were increasing as the week went on and why I almost ran out of space…
Has anyone any idea how to stop it creating repeated ‘back up’ copies ?
