User data cannot be preserved in FLASH on PCA10001?

Hi,

I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update. It works fine if I set system off mode, and wake it up. I can read back the user data from the FLASH.

However, if I disconnect the USB cable, and re-plug it, all user data is gone.

I'm using PCA10001 board from the Evaluation Kit, everything is default. Do I miss some setting that allows me to preserve data permanently?

Thanks.
