Two possibilities:Rideout wrote:I recently bought a couple 64gb micro sd cards off of ebay with the intentions of using one with my RPi and another with my Nikon. Following a tutorial on Instructables.com, I set out to build a Raspberry Pi server. After installing the OS onto the 64gb Micro SD, I attempted to boot the RPI. I couldn't get any signal to my TV or computer monitors. I edited the config file to force HDMI out and that didn't work either. I'm assuming there's a compatibility issue with the SD card. The cards will not work in my Nikon either, even though they work fine in all my other computers.
Has anyone else tried these memory cards and have you had any luck?
Uh, what? Never heard of that. The recommended (and supported) version of Raspbian is available from http://www.raspberrypi.org/downloads/ so use that to test your hardware, and if it works you can then use whatever other weird and wonderful distros you likeRideout wrote:The OS I installed was called Raspian Turnkey Mix by Ghoulmann.

I ran H2testw and here are the results:RaTTuS wrote:download H2testw 1.4 and run that over it [on a windows machine]
that will tell you if it is fake or not
I re-checked the file format on the SD and it turns out it was exFat. I reformatted it to FAT32 and installed Raspbian. I was unable to get it to display on any tv or monitor.AndrewS wrote:Uh, what?

I agree. The instructions were quite lacking. I was a bit hesitant on installing such a dated OS but based on the review comments, people still seemed pretty happy with how it functioned so I figured I'd give it a try.drgeoff wrote:The image file contained in that Ghoulmann download is dated November 2012. 18 months too old to work on a B+.
And what sensible person writes an instructable which tells you to download a .tar.gz file, extract it and write it with Win32DiskImager? (No guidance whatsoever given on how to do that extraction on a Windows PC.)
Thanks AndrewS. I feel cheated. I never fall for online scams. Unfortunately, it's been over 30 days since I purchased the sd cards and my buyers protection ran out. I filed a dispute anyways and contacted the sell but I doubt much will become of it.AndrewS wrote:Ah, so you've actually got a 4GB card, which has had it's firmware hacked to report a 64GB card
It "works" perfectly fine, as long as the total amount of data on the card is less than 4GB (which is why you need something like H2testw to find fake flash memory). As soon as you try to save anything over 4GB, the card will likely inform you that it worked, but when you try to read back the data it simply won't be there.
I suggest you get a refund.
I filed a dispute with ebay and seller agreed to refund me in full as long as I return the memory cards. We'll see how it goes.AndrewS wrote:Dunno about the US, but in the UK there's fairly strong regulation about selling something that isn't as described. Ebay should hopefully settle the dispute in your favour.
So he can re-sell it to another unsuspecting mug punter. You may want to try frying the card by connecting some of the pins to a 12V power supply before you return it.Rideout wrote:

And that seller has a very good rating
DittoI only buy 'sold by Amazon' ones these days; at least I have a decent chance of getting a real card or get my money back.
Lesson learned. I was unaware that people were faking SD cards. I guess it's been a while since I've purchased one.MattHawkinsUK wrote:Don't buy flash media from eBay.
If it's cheaper than a proper shop it is probably fake. The counterfeit rate is so high it just isn't work the risk or the hassle!
