Memory card error

[Crimson Nape]

sectorinfo is new to Windows 10.  I used wmic DISKDRIVE get bytespersector, caption on my Win 7 Pro.   All drives report 512 even though the default size for a FAT structure is 4K.

[TBMx]

as I thought ... formating with a greater clustersize will make the card unreadable for the device^^

all in all: Fat 16 - 512 Byte (or is it Bit?) ... just select the 512 from the drop-down menu in windows for the cluster size

[Surfbear]

could you please check the clustersize of that working card?

open up a command prompt "cmd.exe" and there type (or paste):
fsutil fsinfo sectorinfo x:

x is the drive-letter of your SD-card.

Than Apnea_GM should use that value during the format instead of the "standard size".

512

hey TBMx,

this is what my card shows:

does this info tell you anything other than there is no info
on my card?

I purchased a new card tonight and it doesn't do anything either when I insert it
into the card slot of my Dreamstation unit.

any other ideas are appreciated

reformat it with filesystem = FAT 16 and sectorsize = 512 Bytes. (richt click in the windows explorer on the drive-letter and choose format)

And please give the sd-card a very simple name .. don' leave it completely blank - but just one word - no special chars.

TBMx, I followed the instructions you posted as can be seen here:

Inserting the card in my machine still does nothing to initiate the data
transfer from the cpap unit to the card. 

I'm starting to feel it could be the machine?
Thanks for your attempts to help.

in the dropdown menu where the 2nd arrow points to: "allocation unit size" select 512 there

default for FAT is much larger than the 512 bytes - and just to be over careful - put in a "volume label" ... take "SDCARD" (all lower or upper letters ... just 1 word - no spaces - nothing fancy)

put the SD-card in while the device has power but is not running / blowing out air. - wait some time ... put your mask on and turn it on for at least 10 minutes ... that should result in some data written to the card. (wait a while after turning the device off (just turn it off .. do NOT unplug the power!) before getting the card out of the device ... might take some time before the machine starts / finishes writing to the card)

if that doesn't help either I'm out of options too ...

these are my options for formatting:

open up a command prompt with admin rights. (press start type "command" wait shortly ... right click on command prompt (I hope it is named that way in english) and choose "run as admin")

there put this in (exactly!!! .. copy & paste with the right click of the mouse) and hit enter:
format e: /FS:FAT /V:BEAR /A:512 /X

.. keep your fingers crossed^^

Hey TBMx,

I tried running the formatting per
your instructions and received this response:

I'm ready to request a new machine and see how it goes.
I really appreciate your time and efforts to offer me assistance!

Thank you very much!
