Sleepyhead Software Import

The first time I loaded date from my FIsher-Pakel Icon everything went well and all charts appeared.

I switched to a nasal mask from full face and have gone for about two weeks thinking I was gathering data. Tonight when I
tried to check data the message I get is there is no data on the disk (insert). Was I supposed to erase all info before? It all reappears but that's all. I know I made sure it was pushed in all the way.

I made sure that I'm logged in.. any help would be appreciated.

It was the drive....sorry to have bothered ya'll.
