Can't play own audio files

[henryfm]

Problem 2

I got my Z1 last month and have upgraded to A 4.4.4

I have copied some audio files that I would actually like to listen to to the SD card on my Z1 from other sources (old phone, PC) into folders within the main folder called Music.  There are a number of junk files with garbage music in the Music folder that will play but the desired music files do not play. I have tried Play Music and Walkman.  Both play the junk music but either don't list or won't play the derired music.  In Safe Mode, despite files having been copied across, File Commander claims the folders with the desired files are empty.  Play Music does not list the desired music files, only the junk (which it can play). Restarting the Z1 in standard mode, the desired files have disappeared from the listings, even from VLC (an added app) that at least seemed to incorporate the desired music files, but would not play them (and now after restarting the folders have disappeared!)

A complication is that under Storage I see sdcard and sdcard1 listed by Astro FIle Manager although not by File Commander.

Any ideas about what's going wrong?

For Memory Map, an additional app using maps that have been copied onto the SDcard, there doesn't seem to be a problem!

The SD card might be corrupted

It is supposedly a good quality SD card, a SanDisk Micro Ultra SDHC 64GB SD card, but its worth trying a different one.  I'll give it a try.

Thank you uliwooly for pointing me in the direction of the SD card.  Since your first posting I've been persuing several lines of attack. In summary:  One blogg said that the SD card I had might be too fast.  However, it is listed as suitable for my phone by SanDisk. I tried the Windows utility chkdsk, which reported some errors that had been corrected.  I found websites discussing fake SanDisk SD cards.  I sent photos of the two sides of the card to SanDisk and they said it was a fake...  In parallel, I came across the 'Gold Standard' SD card checker, H2testw which is non-destructive as it writes and verifies files written in free space, i.e. does not overwrite or erase any existing data for a 'valid' SD card. Running this showed that the SD card was an 8 GB card, not the putitive 64 GB.  I've been in contact with the supplier, as you can guess! I'll be checking the replacement with H2testw before I install it!!

I used Windows utilities to shrink the SD card partition to 8 GB (format to NTFS to do so, then restore exFAT after shrinking) and it now reports the proper size and OK by H2testw.  Speed untested...
