So I just received 2 of these cards: Kingston 8GB MicroSD4HC Japanese made, bought off of DealWoot. Both cards have given me an error when I try to copy more than about 940MB worth of data onto them. The Error is "Cannot copy file. The parameter is invalid." Interestingly enough both the Panasonic SD formater program... thing... as well as Windows XPs own format tool report it as having a maximum formatted capacity of 960mb.
Also interestingly enough I found that... I think Panasonic?.. SD cards that are listed as 1GB have 944mb usable. Last time I gave formating the card a go, I did it as FAT32 with 512byte cluster size... and got 944mb usable on the card.
So: is this a problem with my card reader, my operating system, or are the cards fake? I've seen some confusion about this across the internet.
I also find it a bit suspicious that while the cards look fine, the packaging for the cards lists the cards as being Class 8 (!!!) cards.
Thanks everyone! I hope this can get figured out. ^^;;;
[EDIT: Interestingly I just went to Kingston's website, as listed on the product package (www.kingston.com/asia/products) and they list the 8GB MicroSD4HC as coming with 2 different adapters... mine only came with 1. Not sure if that matters on iota, though.]
