2gb Micro SD

[Scottyb410]

So, I plugged in my older 720 today and it GUI said that the firmware required updating. I clicked OK and it came back saying that the card didn't have enough space. So, I formatted the drive using the utility. As it was formatting the purple bar appeared saying SD Card Error.

I tried the utility format again and it failed. The computer sees the card as it should (see photo) but properties lists the used space as 32.0KB with 0 bytes of free space? I pulled the card from the 720 and scanned it using a card reader and it worked fine. I reformatted it using the computer and renamed it SK720. I installed it back into the 720 (correctly) and the same results appeared.

I guess the card has failed?
I am now having great difficulty finding a 2gb card that will work. Kingston has actually discontinued distribution of these cards.
Does Skookum supply them? Art?

I too, plugged in my older 720 today and it GUI said that the firmware required updating. I clicked OK and it came back saying that the card didn't have enough space. So, I formatted the drive using the utility. As it was formatting the purple bar appeared saying SD Card Error.

I tried the utility format again and it failed. The computer showed the card as used space as 32.0KB with 0 bytes of free space? I pulled the card from the 720 and could not format it with the computer, it thinks it is a 32 kb size card and fails on format.

I guess the card has failed?

I could not find a 2 gig card so I tried bought a 4 gig card. It failed right away with the same error.
I tried a known good 8 gig and it is hosed too now. After it was in the 720, windows will not format it either.
If I find a 2 gig card will it work or is my SK720 killing these cards?
By the way I have been using Skookums for years. I really like them.
I have two 720s in camera ships.
I have 3 Goblins each with a 540.
This is the first issue I ran into.

4 gig and above cards are SDHC cards. The SK720 blue does not support SDHC cards. You need to use a 2 gig or smaller SD card. It will show the SD card error when you plug in an SDHC card, even if the card and SK720 blue both work perfectly fine.

Also, per the Skookum wiki entry on SD cards (http://www.skookumrobotics.com/wiki/...in_Flash_Drive), the cards have two separate electrical interfaces. It is possible that the electrical interface on your 2 gig card that the SK720 blue uses is burnt out while the interface that the card reader on your computer uses is still functional. Georgi's suggestion to get a replacement from fleaBay is a good one.

And finally, be very careful taking your SD card out of the SK720. Even a tiny scratch in the wrong place on the plastic coating will destroy a card.

Yup, a new 2gb Scandisk card fixed it all.
Everything is fine now
