I am using the LS-100 with a 64GB SDXC card. When I use internal LS-100 memory everything is fine. When I record files to the SD card the wrong file "last modified date" shows up when viewing the LS-100 file via USB on my computer. If I copy the file from the LS-100 SD card to my computer, the wrong date remains. The correct date is set on the LS-100 and on my computer. If I use the SD card on my computer wiithout the LS-100, I can store files and they show up with the correct date. The LS-100 picks a Dec. 2010 date strangely enough. I would appreciate any cofirmation of this problem on other LS-100s. I actually exchanged my 1st LS-100 for another and the 2nd one has the same problem. The date is set-up properly on the recorder.
