I have a strange problem with my Sansa e250 v2. When I add a micro SD card and then copy an album or a music folder over to the extended memory, it seems to work just fine - the windows explorer shows all files and data in place and correct. Upon disconnecting the player from the USB cord, it goes through the database update, and then the artist and album information is lost. The songs can be found under “unknown” artist, the albums just do not appear at all. This, of course, creates an extremely long list of “unknown” artist songs.
Upon reconnecting to the computer and looking at the files I note that the data still is there on the external memory, but the artist name is indeed replaced with “unknown”. If I examine the data in the Windows media player I notice that all the album names and artists are replaced with Chinese or Japanese hieroglyphics. The data, as transfered originally, shows correctly in either Windows Explorer or Windows media player. It only gets corrupted when the USB cable is diconnected and the “database update” action tales place.
Strangely, I can take exactly the same folders and load then into the internal memory, and everything works just fine - both the artist name and the album name appear on the player. I have tried both a 16 and an 8 GB card (from San Disk) in the player and the results are the same.
Another odd thing is that when the card is removed from the player and plugged into my computer via a USB adapter, it says that the card is write protected, and I am unable to unprotect it. However, back in the player it is writeable again! My computer runs Windows 7, and the player has the latest firmware.
Sorry for the long post, but any suggestions would be welcome.
