Nanocom Evolution SD Card not reading

**one_iota** · 8th March 2011, 01:01 PM

Fellow users,

I bought a 2GB SanDisk SD card as recommended for the "Evo". (If I recollect correctly although I can't find the documentation now)

The "Evo" doesn't recognise that the card is present and tells me so. It is inserted correctly, not locked and the card works on my computer as tested via a card reader. The card is formatted as FAT.

Am I missing something here?

Mahn,

Yep... read the same doco... up to 2Gb, FAT formatted but NOT a HD SD card if memory serves me right.

I have a standard SD 2 Gb FAT format card and it works....

Mine is a plain old SD not an HD SD but still no go

Have you tried all the FAT formats? There are about 3 different FATs from memory.

Yep all formats tried.

I think the evo only likes some types of SD Cards. I used a working Transcend 128MB card and the Nanocom would not write to it. I put it back in the PC and it was unrecoginsable to Windows. I could not even reformat it. Lucky it was just an old card I had lying around. I also had a 2GB microSD card which works fine in an adapter.

I have now tried 5 different SD cards, all meeting the spec, and all reading fine with various card readers.
The Nanocom has not recognised any of them. So thus far I have been unable to back anything up.

Hi MTB

Maybe it's a Sydney thing

At least I'm not Robinson Crusoe.

The Evo makes a noise when I insert the card after it is powered up and switches off when I remove the card....don't know if this is normal behaviour.

However regardless of whether I have the card in before switching on or after, still no show.

Maybe Colin will wander by later with some clues?

I used a cheap 2GB SD card which could be read in the PC no problem (FAT32 I think), plugged it in to the Evo and powered it on.
Then did a backup, which took about 3-5mins.
Powered the unit down and removed the SD card.
When I put the SD card in the PC again it was no longer readable.

I'm guessing that it has been formatted to something other than FAT32 by the Evo, at least that is what I am hoping.

Cheers, Paul.

Just wandering by

It seems that the Evo is currently a bit Pickey about which cards and formats it is compatible with.

I am of course sorry for anyone struggling to find their own working solution, and have instructed the addition on an option to also purchase a known pre formatted and tested as working SD card from our web shop.
Also the pre testing of the SD card hardware connectivity as part of the pre shipment hardware testing.

But, in this case, i really do have to stand up for the origional developer of the Nanocom Evolution software. From my own experience, i know that there is not only a huge varience in communications from different cards from different manufacturers with different speeds and timings, but also as many variances in formatting. This can all be easily and seemlesly catered for in a PC, but not so easily in a dedicated microprocessor based system as the Evolution is.

In fact any degree of FAT compatability with a PC is really very difficult to achieve at all and is not something we would have taken on lightly.

That being said, already improvements have been made to this aspect of the system, for release with the next upgrade, that will widen the range of acceptable cards to also include SDHC standard and also allow formatting from the Nanocom Evolution of any SD card by the unit itself to the required format.
