Sleepyhead software- can it corrupt the SD card?

Post by droopy snoopy » Wed Jan 28, 2015 1:49 pm

I just got my 1st CPAP machine, and the DME stated that if I tried to view the information on the SD card, it would corrupt the card and they would not be able to see my compliance data. Is this correct if I use Sleepyhead software? I would like to be more knowledgeable about my treatment, and the charts I see posted on this forum are very interesting.

Thanks in advance!

Untrue. Some OS such as Windows 8 may add a file, but all you have to do is slide the lock and lock the card before you put it in the computer and then unlock before you put it back in the machine.

absolutely, positively a complete and total lie.

sleepyhead *cannot* write to your sd card, it doesn't have any code in it to do that.

and, for another thing, even if you put a BLANK sd card into the cpap, it will write the compliance data onto the card from it's memory. your DME is either lying to scare you, or simply ignorant of the facts.

pop that card into your computer and make yourself some charts! (link below to the current version of SH)

the prs1 machines don't care about the index files that macos and win8 put on there... it's only the resmeds that are persnickity.

That's a relief! I plan on downloading it tonight, then. Can't wait to see what is says. Just got my sleep study results yesterday, and they were pretty grim.

Welcome to the forum!

If you use a computer with Windows8.1 then trouble may exist. Win8.1 wants to, by default, write files to any external drive. The SD card is seen as an external drive. ResMed does not like this. So long as you write protect the SD card (slide the little tab in the left front of the card to the rear position) you will be safe. Just remember to write enable it prior to inserting back in the AS10. Sleepyhead only reads the data and doesn't write anything to the card.

Good Luck!

What the DME is probably reacting to is only true under certain circumstances. Since you have a Phillips machine it should not be a problem for you though.

SleepyHead reads, but DOES NOT write anything to your card. So SleepyHead would not corrupt the card.

The problem (as was mentioned above) is that some operating systems (Like Windows 8 or 8.1 and Mac OSX) do write small data files to any SD Card which is inserted into that computer. Those files don't normally cause a problem for the user, but it seems that ResMed machines don't like those little extra files to be written onto their card and sometimes the card data becomes corrupted.

The solution for those who have a ResMed machine is to "lock" the SD Card after it is removed from the back of the ResMed machine by sliding the little white "tab" on the side of the SD Card to the other end of the card (towards the end of the card away and opposite the gold pins) as this "locks" the SD Card. This will prevent the computer's operating system (Windows 8, Mac OSX, etc.) from being able to put that file on the SD Card. The important thing is to remember to slide the white "tab" back to the unlocked position (towards the gold pins) after you remove it from the computer and BEFORE you insert it back into the ResMed machine. If you don't your machine won't be able to write it's nightly data to the card the next time.

As I mentioned above Phillips Respironics SD Cards are not so vulnerable to corruption by these little files... so you should not have to worry. Although it probably isn't a bad policy to lock any SD Card before inserting it into any computer as a general policy.

What the DME didn't tell you is that most of the later models of the Phillips Respironcs machine have an internal hard drive to which the machine keeps a duplicate copy of the compliance information. So the DME can get the information directly from the machine (which doesn't get corrupted since it never leaves the machine).

Thanks everyone! I just reviewed my first 5 days of data, and it looks like this is working for me. AHI under 2 every night. I am on the road to feeling better!

BTW, I know I entered by machine info on my profile, but I don't see it on my post. ?

If you have a 60 series machine you have to scroll down to the section that says 60 series like mine. Also chose the 60 series humidifer with heated hose. You can find your REF# on the bottom of the blower after removing there water tank. If that number is x60 you have a 60 series.

I think you probably chose the wrong selection...some of the older choices have broken links and I bet you chose the wrong one.
Look on the bottom of the blower unit for a 3 digit number with probably DS, REF or P in front or behind it and tell us those 3 digits and we will tell you which choice to make.
I doubt you have an old machine that has been discontinued.
I also bet that you have chosen the wrong humidifier as I bet you have a 60 series humidifier...but tell me the 3 digits off the blower unit and I will tell you exactly which choice to make in the equipment menu.

I chose "PR System One REMstar Pro CPAP Machine with C-Flex Plus."

Still not showing...

I send a screenshot, but don't know how?

What is the number on the bottom of your blower? The one you chose doesn't show because it is an old one no longer sold.

That's the model number 450 and that model has been discontinued (nearly 3 years now) and it is unlikely that you have been given that machine unless you got it second hand somewhere. That link is broken and is why it isn't showing up...that model is no longer being sold.

The new model of that machine is the PR System One 60 Series Pro CPAP and is model 460 on the bottom of the blower unit.
I suspect that is what you have been given if you got your machine from a DME and not second hand.
The correct humidifier choice for the 460 model is the
PR System One 60 Series heated tube humidifier with heated tube (even if you don't have the optional heated hose at this time). It's the same humidifier that I show in my profile.

I lost my original ResMed card, and went and found an old camera and used the card from that. I backed up the pictures on the camera card, but they are still there after a couple of days in my A10 machine. And the camera card is back in the camera, the pictures still show up, and the camera is only a bit puzzled by the cpap data on the card. I bought a new 8GB card and made a brief attempt to copy my saved 3 months of data on to it, but my mac refuses to write on the card. Disk Utility marks it write protected or not correctly according to where the slider is, but Finder refuses to write on it no matter what.

So at least my experience on the mac is that it's impossible to corrupt the card with the mac. And the compliance data (which is the only thing any dme will care about) is in internal memory that is in the machine and when you insert a different card the machine copies that data over. The metadata on the files has the new date, but the files are identical:

[cathyf-laptop:~] cathy% ls -l /Users/cathy/Documents/SleepyheadBackups/5Jan15/Identification.tgt
-rwxrwxrwx 1 cathy staff 283 Sep 10 23:35 /Users/cathy/Documents/SleepyheadBackups/5Jan15/Identification.tgt
[cathyf-laptop:~] cathy% ls -l /Volumes/NO\ NAME\ 1/Identification.tgt
-rwxrwxrwx 1 cathy staff 283 Jan 11 15:41 /Volumes/NO NAME 1/Identification.tgt
[cathyf-laptop:~] cathy% diff /Users/cathy/Documents/SleepyheadBackups/5Jan15/Identification.tgt /Volumes/NO\ NAME\ 1/Identification.tgt
[cathyf-laptop:~] cathy%

That's my experience with a mac running 10.6.8 and a resmed A10.
