Dropbox Sync is changing EXIF Data / Meta Data of pictures

HI all,

last time I recognized that roundabout 20.000 pictures has the same acquiring date (23rd of July 2005). First I thought it is some wrong setting in my dropbox but when I had a closer look I can see that meta files and also EXIF is changed on these pictures. The acquiring date was changed for some reason! This happened on around 20k pictures of around 38k in total.

I stopped dropbox sync on Readynas immediately. Afterwards I made a small test folder and indeed it happened again when pictures had been uploaded to dropbox from readynas. I guess this happens since one of the last upgrades but not sure. It was working before - for sure! I also did a sync with dropbox client on PC to Dropbox and no data was changed. This points to the readynas dropbox sync.

I don’t know if there is something in my setup wrong or is there is something wrong in general.

But anyway - around 20k pictures are messed up and in some cases I cannot bring the original data back!!! I'm really pissed off...

I tried with every program to bring original data back but without success.

I always thought my readynas is helping me to safe my data and have everything secure. Since all my backups to other drives originating from my readynas I have no original data anymore.

I lost trust in this hardware and I'm going back to use local storage with one or two external hard drives because I don't know what happens to my data as soon as it is on the Netgear...

Did anybody else made the same experience?
