The only other factor is that this was my first recording       with an 8 GB SDHC card. I previously used cards up to 4 GB, but now the       8 GB costs less than the 4 GB. In my recordings, I can get 3 hours of       music on a 2GB card, so I did not exceed that 2 GB threshold.              I am hoping that I just had one single bad SD card, but time will tell.              Thank you for your interesting post.              Mort              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
