Files in MicroSD card aren't being shown in File Browser or Database on Clip+

[tristan]

Hi,

I have the same issue with my Sansa Fuze v2 + 16GB microSDHC. I tried to install the current build to r28932. As of now it works OK. microSDHC is now appears on Files and Database.

This problem has been resolved.

Thanks.

Hi!

I still having this issue with my Sansa Clip Plus + 16GB Transcend microSDHC card !


There is all available for me debug information:

Player model -- SanDisk Sansa Clip Plus 4Gb
MicroSDHC card model -- Transcend 16Gb class 2, TS16GUSDHC2

Rockbox daily build version: r29037-110112 (problem still also exists with stable and all previous daily builds)
HD1: Not present

NOTE: In custom RockBox builds with USB support card is ALWAYS detected after player disconnection from USB port.
After powering player off and on card IS NOT detected. In these both cases information in "Debug - View disk info" menu still the same, as posted.

NOTE 2: Sometimes (if card is detected) I can see corruption of screen font bitmaps (digital garbage in place of letters), but playback of music still OK.

Thank you for reply!

Hi,

I also having this issue with my Sansa Fuze.
I can not see the microSD in the file browser. If I transfer files from my Ubuntu workstation
to the Fuze, after 1-2 minutues the file system will be automatically remounted readonly.
I already tried a file system check and formated the card again. No change. Switching to
the Sandisk OS, the card seams to work fine.

I am having this same problem. I have a
      Sansa e280 running Rockbox 3.7
      Sansa Clip+ running 3.7.2, and now running r29082-110118
      Sandisk microSD 8gb
      Sandisk microSD 32gb

The problem is that the Clip+ running 3.7.2 or r29082-110118 does not recognise the 32gb microSD. The Clip+ running 3.7.2 or r29082-110118 will see the 8gb microSD

Running the original firmware the Clip+ will see the microSD 32gb card without problem.

Interestingly enough the Sansa e280 running RB 3.7, will recognise the 32gb microSD and the 8gb microSD.

When I insert the 32gb microSD card into the Clip+ running 3.7.2 or r29082-110118 the disk use symbol will flash up, but the word <microSD> will not appear in the file list.

Looking under Rockbox Info it says "HD1 not present".

I tried formatting the microSD with mkfs.vfat under linux with the option -F 32, to have a 32bit file allocation table, but that made no difference.

I don't see how I can delete my post. It turned out that I incorrectly updated firmware. 32Gb card works for me quite well with r29093-110119. Thanks to all developers who make this project possible!!!

While I was quite happy, I got "Divide by zero at 3080EB08" while listening to ape+cue . Kind of sad... I'll see where to report it.. I'm not sure if I'd get it with stable firmware.

I'm also having difficulties with Clip+ (AMSv2 variant 1) and Transcend 32Gb Class 2 card (SU32G Rev 8.0, Prod 12/2010,). I'm a newbie user and I have no coding experience for these devices, but I'd like to help at least by testing firmware/providing debug data. I guess FS#11798 should be reopened.

I guess FS#11798 should be reopened.

I think you can just use FS#11870.  I renamed it to make it more clear.

Please, check page http://www.rockbox.org/tracker/task/11870 for test patch.

Or test precompiled rockbox (for Sansa Clip+) with this patch from http://rapidshare.com/files/444673217/rockbox.zip

[mlt]

With (r29141M-110126) or without your patch (r29086), I can use Transcend 32 Gb card in my Clip+ Is there anything I should pay attention specifically when using your build

I'll be very grateful if you check the stability of the player with my build. In particular, the normal operation of SDHC-card's hot-plug and absence of long delays ("freezes")

[mlt]

It may sound silly. Is it safe to extract a card while a player is on? There is no option like `unmount` or `eject`. I usually insert/remove my card while the player is off.

Stop playback of files from SD card and begin playing any file from internal memory and, IMHO, you can safely extract a card.

[mlt]

I tried to insert/remove card. Your build doesn't make any noticeable difference in my case (Transcend 32 Gb). <microSD1> folder seems to appear instantaneously for me with either builds. Folder is still there upon removal of the card, but it disappears when I try to navigate anywhere. I'll try to use your build for a while.

P.S. With either build I get 25 Mb/s for microSDHC card, though it shows (in debug data) 50 Mb/s for built-in memory. I guess it is just the matter of the card class.

Same problem here. Got my 16GB microSD today and it is not recognized in rockbox, only in OF. Sansa Clip+.

If I can be of any help to fix this let me know. Although I'm no C developer...

[mlt]

What version did you try? Stable release (3.7.1) doesn't work for me, though anything recent works fine.

I use 3.7.1 but would like to try a newer one.

Edit:
If I could find it...! I'm kind of stupid. Found the link "current build".

I'll try that now. Thanks!
Post Merge: February 04, 2011, 11:26:03 AMWow, seems to work now! Using r29205.

For the ones who forgot how to update (like me):

Just start the RockboxUtility and select the Tab "Install". Choose the option for the current build and go.
