Problems getting HelloRamDisk running

Using Arduino Storage
#1

I actually had HelloRamDisk and RamByteReadWrite operational when RamDiskToSDFat was giving me problems. While trying to get the latter example to work, all the RamDisk examples stopped working. I decided to reinstall IDE and start over. Still HelloRamDisk is not working. My import library contributed list contains RamDisk and M23LCV1024. I had also added SdFat to the contributed library, but for some reason it's not listed now.

When I run HelloRamDisk I get the errors 'RamVolume' does not name a type & 'RamFile' does not name a type, etc.

My files hierarchy is:
.../libraries/RamDisk/RamDiskDemo20140412 (Under that I have 3 files:)
/M23LCV1024/.h & .CPP files
/RamDisk/...
/SdFat/...

Any ideas what's wrong?

Thanks Gerry

OK, I figured it out. Even though RamDisk was listed in the contributed library, there wasn't anything in it. I didn't know it before, but you can open a sketch and use "Import Library", to load the #include files into your sketch. That's a good test to see if the library is really included. Nothing came up when trying to load the #include files for RamDisk. It's all working now after restructuring the RamDisk files.

Not sure this is of interest, but here are the results of the RamDisk examples:
