Originally posted by reytor I have total of four Transcend 16GB Class 6 cards. Two of them have been used in my K-7 and as pendrives in computer(s). Other two have been in a Canon P&S. So far I've had no problems (permanent or ocational), but I tend to be very carefull not to change lenses or take out the card while camera is on. The same when connected to PC, I always first segure that OS (windows & Linux) has given permission to disconnect or the PC is off.
Oh, And I format the card in camera after each download to PC.
Tried shooting continous HD with the transcend ones?
Also, it's not necessary to format the card after each download. That is stupid and eats up write cycle counts. A memorycard (while having a lot more writes now than in the past) will still eat up write counts if you do any writing (formatting for example).
The seek time of memorycardes is virtually nill, which makes it pointless to format to get a "fresh start" which might be the reason why you would want to format a normal harddrive (no fragmentation issues).
