Can a car DYNO wipe an SD card?

[COSMOPARADISE (Nick)]

Had my car dynotuned today and while it was on the dyno I took a video of it with my phone near the wheels. When I got home to my surprise my SD card in my phone, where all my photos are saved to, is wiped clean, from .5 GB free to 1.85 GB free. Tracking back my movements all I can think of is that kneeling down next to the rollers on the dyno, which most probably have a huge magnetic field around them, may have been enough to sterilise my SD card.
Thoughts anyone?

Movement through a magnetic field will wipe credit and bank cards with a magnetic strip.

SD cards operate on a different principle. They are immune to magnetic fields. Unless it was as powerful as something like an MRI device.

You weren't run over by a delivery truck were you?

Hey thanks for that info Marty, appreciate it.
Haha JenChris that may be a possibility, I don't recall...
My conclusion then is that SD cards suck..
