hehe, called HAMA.....so it means the guys are liars.
Well, all what I can tell you is: please read something, for instance wikipedia or similar. It is the truth, that sticks (any kind of flash) must erase on a block-wise basis, as result you have to write back again each byte of the block.

Further, I changed just one stick under warranty, because I dont keep the invoice, as this stuff costs a few bucks.
Sorry, Darius - I'm not willing to discuss about things which are well known, it doesn't make any sense -the only point I suggest is: do a backup, I promise you need it some day.
As sticks are cheap, it is not worth to go for a 20mile drive just to change a stick under warranty for 5 EURO. Cheaper is to throw the stick......
And I buy them when I'm on the way - elsewhere..........
An the last point: all tests with sticks have been done with OS windows.....thats the reason why some tests got as result several millions write cycles (as I mentioned - the driver and a smart control handle this).
have fun
