We have several field crews out recording data using ArcPad 10.2 and Trimble 3B units with an AXF and custom forms. The forms were modified in ArcPad Studio, and differ mostly in formatting from the forms automatically generated from the geodatabase. The GDB does contain several domains that are used in the forms. We've also been using the Add XYZ applet found on the ArcScripts webpage.
One unit in particular is giving us problems. Twice in the past two field sessions, the user collected data throughout the day, and then closed the map when heading out of the field. Upon returning to the hotel room to back up the data, they realized that all of the day's data was simply gone. Missing. The previous day's data was still there, but everything from that day ceased to exist.
Throughout the day, the points, lines, and polygons recorded were visible on the map, so you'd think they were saved and quite safe, but evidently that was not the case. The first time this happened, all of the day's data was lost, except for the first point taken that day. The second time it happened, all data recorded that day was lost.
Does anyone have any idea what may cause ArcPad to not retain saves to an AXF when closing the map? As I understand it, changes to the AXF should be saved automatically once the forms are "OK'd" and exited from. The fact that this has only happened on one unit, makes me wonder if it is a hardware problem, but if data corruption is happening on a hardware level, that doesn't explain why only select data from one day at a time is being lost. My second thought is that perhaps the installation of ArcPad itself if corrupt.
I'll post with any solutions or insights I come up with once I have the unit in hand, and can perform tests on it myself. Until then, I welcome any experience, workarounds, explanations, or thoughts concerning what may be happening here.
Thanks.
