Purging Data

Post by Thumper1947 » Mon Oct 03, 2022 8:28 am

My SD card for Oscar has 5.9 GB of data on it and I will eventually run out of space.I would like to lighten the load by purging data, but the only option I see is purging all data. I would like to leave some of the recent years data on there. Is there any way to do that, or do I have to obliterate it all. Thanks.

I believe that once the card fills up, it starts to write over with the newer data. (Not sure). I have been using a 2GB card for years without a problem.

Thanks LSAT. I was wondering if all this data is also being stored on my computer. The reason I ask, is I have purged data in the past when I changed machines and the responsiveness of Oscar greatly improved.

As a rule, the oldest data is overwritten first.

Purging data is an OSCAR term, I think it refers to the data in the computer's database, not on the card...

You can have your machine reformat the card if you want to - it's some somewhere in the clinician's settings. Or you can simply reformat the SD on your computer, and your machine will then prepare it for new use.
