[ale] Can't write to SSD

[Chris Fowler]

I'm running into an odd issue where I can't write to SSD. Files do exist, but on reboot they disappear. This just started happening. I do not see any error messages and fsck.ext3 is not reporting errors. Any attempt to write a file is successful. I did notice a reboot is not required. Mount and unmount can recreate this issue.

Creating a blank file on sda1 
EXEC: touch /mnt/nvroot/data/test.empty 
Is it there?
