I just purchased an 8GB Clip+ and installed a 16GB SDHC card. When I try to mount the Clip+, I am able to see the SDHC card (SDE1: 15.2GB), but not the internal memory of the Clip+.
I am running Puppy Linux version 4.2.1, and have tried the mount utility using both the default probedisk and optional MUT methods. The result is the same.
I found out that my problem was “stale NFS file handle” on /dev/sdd (caused I think by unplugging the Clip+ without first unmounting it). Unfortunately, there is no easy way to fix that problem. I ended up re-installing puppy linux. Luckily, that is less of a hassle with Puppy than with some other Linux’s. Now I make regular backups of my pup_save file.
