You mean acknowledged officially in writing on letterhead paper? No.
Inofficially: yes.
Also many people have confirmed this behaviour, at least on the cheap
"standard" (versus "industrial grade") CF cards.
I recommend to specifically ask your CF card vendor / distributor for
a confirmation and guarantee (in writing) that it is safe to turn off
power while writing to the device. Guess what you will get?
Best regards,
