Corrupted SD card (resolved)

I took the SD card out of my device, and it looks interesting.

there is this file: tables.TP
dated: 8/22/2082 7:20PM PDT

There is another one: EFIV.HTM
from: 8/22/2034 (also at 7:20PM PDT)

I was unable to delete the tables.TP* file, so I copied all the content from the SD card and then slow formatted the SD card. It is a very slow card (Kingston, class 4) with a write speed of ~5MB/sec, so that took a long time.

And putting the card back in and booted and get red-red-red.

Looks like the problem is this:

I guess it doesn’t like the format of the SD card now

Problem is now resolved. I reformatted the SD card with the official SD card formatter from here:

The 5.0 version I used does not appear to give any options for the filesystem type and it chose FAT32 (which is what I used when I formatted it from Windows). I know that some libraries are picky about some details for the formatting and work better when using the SD cards formatted by the official formatter.

I removed the file with the unusual name and also the one from the future. The File Manager and Editor is much happier now and is showing me all the files.
