Micro SD Card Not Detected

[Bruiser13]

I have a Sandisk Sansa e260 v2 with Rockbox 3.7 installed.

Recently purchased a 16GB Micro SD Card, however it is not being detected by the mp3 player.
Error Message I receive is:  "micro sd init failed : -2"
The machine then shuts over and repeatedly tries to reboot, only keep getting the same error message.

Could this be a problem with the 3.7 version. I previously had a similar player that I used with 3.4 that worked fine.

Any help is appreciated!

Try that current build at least and see if that fixes your problem.  If not, you'll probably have to wait until the SD driver is further improved.

3.5 was actually the first version of Rockbox that ran on your player, so its probably not a regression.  I suspect you were actually running rockbox on a different model of sandisk player, one with a more stable SD card driver.

yes, my previous player (lost it) was a e250r v1

Did you try the current build yet to see if this problem has been fixed?

[Bruiser13]

yes. I tried a number of things:

Current build
Version 3.5
Formatted the player and reinstalled firmware and Rockbox

It's supposed to be a refurbished machine, so I decided to return it and see if I could try another one.

I checked out the 16gb Micro card with h2testw and no errors were reported, so now I'm at a loss for anything to try next. Could be a hardware issue?
Thanks!

Its probably just that the SD card driver doesn't work right with your card.  It'll probably be fixed eventually.

I've used micro sd 16gb cards in the past without a problem. Doesn't the same driver work with all micro sd 16gb cards? thanks.

Was that with this player or your previous one?

[Bruiser13]

That was a previous player and a previous card. Don't all micro sd cards use the same driver?

Not all memory cards are the same, even though they are *supposed* to be. Some deviate slightly from the standard in ways that may affect their compatibility with some devices/operating systems.

Edit: Also, the driver for the SD card slot is different on different players.

[Bruiser13]

I returned the SD card that I had a problem with and purchased a different one and the player now seems to work fine.

Thanks for all your help. Apparently there was some reason that there was a compatibility problem.
