Inserting the SD Card of the old device into the replaced Philips Dreamstation Cpap

Inserting the SD Card of the old device into the replaced Philips Dreamstation Cpap
Hello guys, today the old Dreamstation Device with foam problem was replaced with the new Dreamstation device. I backed up Sd Card contents before going for replacement. I copied it to the SD card inside the new device and ran the new device. The new device did not see my 720 days old data, it started from scratch as if I had reset it. When I removed the SD card and connected it to the PC, I saw that it created a new folder. It doesn't read the old folder. I changed the name of the old folder with the new folder, again all data seems to be zero. I backup the old one with Oscar. Is there a way to continue with the old data? Please forgive me for my broken English.

Best Regards

We sometimes recommend creating a new profile to use with the new machine. This keeps the data separate, but you can always look at the old data. For example your Dreamstation 1 data could be under your profile Delmos, and the new data could be Delmos2. I would have deleted or formatted the SD card for use in the new machine.

A CPAP writes its serial number to the SD card to make it unique to that CPAP. Only one CPAP's serial number can be on the card. Even though the old CPAP's data files are on the card, the main files that would point to this data no longer exist. For all practical purposes, these files are now orphaned.

Thanks, I created a different profile as you said. In OSCAR, I can see the old and the new separately. I put the old Data as a separate folder on the SD Card to show when I go to the doctor. I guess this way the Doctor can also access the old data in the SD Card.

Thanks, that's what I thought. PROP.TXT device serial number and other information. I arranged it according to the information of the new device, but it did not work. I will keep the old files on the SD card as a backup. I hope he sees them when I go to the doctor.

That is only true for Resmed, not for Philips.

A Philips SD card can hold many different machines without issue. Each machine has complete data in its own directory (named after its serial number).

The only time you might have a conflict is with two DS2 machines whose serial numbers collide due to a badly designed hash (first 3 or 4 digits match, if I remember correctly). But that’s rare at this point.

The card should be structured as:

P-Series/
    (8-digit name base on serial number)/
        Prop.txt (or prop.bin for DS2)
        P0/
    (Possibly more machines’ directories)
    Last.txt

OSCAR will import all the machines it finds. Official software typically only imports the one folder identified by last.txt.

So if you want your doctor to be able to see both, you’ll want 2 SD cards. You can use the above tree to structure them as needed.

Confused Sorry for providing incorrect information.  Until sawinglogz's post above, I thought it was standard practice for all CPAP brands.

I think the only thing that's 'standard practice' for CPAP machines is the physical size of the SD card - and I think the Philips travel CPAP uses microSD cards!

Thank you very much for your reply. I really appreciate you and those who contributed to the Oscar program. Since it was the first day, there was no data. After reading your post, I took the SD Card out of the device and connected it to the PC. After creating a new profile in the Oscar Program and choosing "Cpap importer", he saw the new device as you can see in the attached pictures. After importing, it combined both old machine data and new machine data as you can see in the pictures. I am very happy now.

Kind regards
