Two things happened yesterday that's got me a little flustered.
For some weird reason I was unable to update an app from the MArket. The download kept failing. Did not think much about it. It was an app I rarely use.
Later in the day I noticed weird stuff happening and it seemed to always occur when I was trying to write to the SD card. I was downloading USGS maps to my Trimble Outdoors app but the cache files would not stay put. It acted like it was downloading and writting them but later when I panned back to that area the map tiles was missing so it downloaded again.
So I decided to download all the files in a zip file and copy to the SD card. I could copy about ten files (each about 50kb in size) and then the copy function would fail. The droid was mounted by USB. I then pulled the SD card and placed it in a card reader and noticed I could not copy anything to it or from it. I could read from it just fine. All my music would play. Pictures display just fine in Gallery. The only issue was when it had to write to the SD card or try to copy from it. And I could not delete any files.
So this morning I loaded it in the card reader and I am picking one directory at a time to copy them to my laptop for backup purpose. I got into the 11th directory, a folder that contains more maps for the BackCountryNavigator program and it locked up tight after copying about 75% of the map tiles (theres 190,000 map tiles in that folder). Aha...there's got to be a bad sector or a corupt file in that directory. And I can't delete the folder.
Found one more folder that had a similar problem and I tried to cancel the copy function and it is locked up tighter than a drum.
I got most of my music and pictures and now I'm thinking it's time to try a format. If that fails I am off to find a good MicroSD card. I don't care how much it costs...I just want something reliable. Any suggestions?
