Just got in a computer that's used in the field, it runs a program that will realtime record data into a database file, the guys that used it reported back trouble with the computer - among other things they did have to reset the computer by turning it off.
They also said that the database file they recorded to was set to "0" (size) after the reboot/crash, and this happened to multiple files, causing data loss.
I'v had a bit of look on the computer and was able to crash it once, but when I rebooted then I realised that automatic update was on, and it had been downloading/updating, can this updating cause main disk and/or files to become "locked" in some way, and might it cause dataloss?.
(I know auto update should not be on such a machine, but for some reason someone have left this feature on).
Also noticed that some files in the "data directory" the data is recorded to have gotten a "lock" icon on them.....
Any info would be appreciated.
