SD sometimes gets 'undetected' and turns into SD032

Your system information

• SteamOS version: 3.5.7 stable
• Opted into Steam client beta?: [No]
• Opted into SteamOS beta?: [No]
• Have you checked for updates in Settings > System?: [Yes]

Please describe your issue in as much detail as possible:

Describe what you expected should happen and what did happen. I boot up my deck and some boots, next to where download happen I see and SD card Icon. When i check it or the storage tab, i can see my sd card is now read as SD032, i get asked to format it and it says it has about 30mb of space. This immediatly gets resolved by either pressing the power button and sleeping/waking the deck or removing and reinserting the SD CARD. I have seen this happen now on 3 separate steam decks with different SD Cards. I have seen this on a friends 256 lcd (on 43.5.7), my old one, my 1tb oled and my spouse's 512 oled. 1tb oled is using a 512 Sandisk Pro SD and the other card is a 1tb sandisk pro black. I dont know if there is an issue with this brand now, but my old LCD deck still has one of these 1tb cards since i bought two back when and it never had this issue since its still on 3.4 The only common thing I can see is the card brand and 3.5

Steps for reproducing this issue:

1. Use a sd card regularly on 3.5.7
2. Leave the deck alone for a few days
3. Turn it on, 50% chance it doesnt detect the card until you reboot

Can anyone run the following commands when this problem happens, and paste the output here ? (before rebooting or ejecting the card)

sudo lsblk -d /dev/mmcblk*

sudo blkid /dev/mmcblk*

mount | grep SD032

sudo journalctl -b | grep -E 'mmcblk|steamos-automount'

Thanks for the logs @Epicbigfoot , this is the interesting part:

NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
mmcblk0 179:0    0 30.6M  0 disk
[...]
Jan 09 21:12:00 steamdeck kernel: mmcblk0: mmc0:d555 SD032 30.6 MiB

So the drive is detected as a 30.6 MiB SD card at the kernel level.

Are you all using a SanDisk SD card? It might be a hardware problem, as it seems that this issue has been noticed by many users in different platforms:

• Google Chromebook: https://bugs.chromium.org/p/chromium/issues/detail?id=1029230
• nVidia TX2: https://forums.developer.nvidia.com/t/sd-card-shows-wrong-size/167097
• ASUS Transformer TF700 tablet: https://xdaforums.com/t/q-32-gb-microsd-showing-only-30-mb.2140977/

• PC (Ubuntu): https://unix.stackexchange.com/questions/205247/sd-card-doesnt-work-anymore

What's interesting is that you all seem to be having this problem with SteamOS 3.5, this could indicate a regression in the kernel.

I use a SanDisk Extreme microSD A2 1TB

Im also using a sandisk card. Is there a fix for this? It literally never happened for the year i had my deck before 3.5

[ffrasisti]

has this been noticed by valve? https://steamcommunity.com/app/1675200/discussions/1/4038102696016939586/?ctp=4

[st235]

I also use SanDisk 400Gb card, also experience the same issue

[R3DR4V3N]

I too am having this problem as described by the original post with my launch model Steam Deck on SteamOS 3.5.7 with a 256GB SanDisk micro SD card.

[ffrasisti]

Its probably a problem like @betogg mentioned. Question is, is this being worked on?

[lutzgooren]

My logs are identical to the ones from @Epicbigfoot - Also 1TB SanDisk Extreme PRO card. First noticed it after plugging it into my OLED Deck back in November. Never noticed it on my LCD Deck before and I don't think I had that one on SteamOS 3.5 yet.

[BrunoTheMad]

Having the same issue reported here. I have RMA'd my 1TB Limited Edition OLED Deck Twice, and the issue has occurred on all three units. The issue occurs using three different types of 1tb capacity sandisk cards:

Sandisk Extreme Pro 1tb Sandisk Extreme 1tb Sandisk GamePlay 1tb

I did notice this problem occur once on my original LCD deck, but after changing to a different microsd card the issue did not occur again.

I attempted to use a lower capacity 512gb Samsung Pro Plus Card, and that card did not seem to suffer the issue. Same goes for a 1tb Lexar card, no issue.

One thing to note is that the Sandisk extreme and extreme pro cards have a sticker on the back that makes removing the card from the slot an ordeal since it can get stuck. Not sure if that is related to this issue.

[ffrasisti]

This keeps happening. I visited my dad who got my old LCD deck and never upgraded. I updated it to the latest stable and sure enough, it does the same thing with the sd card that had zero issues before. @kisak-valve is this being looked into? It's really really irritating

[ffrasisti]

My logs are identical to the ones from @Epicbigfoot - Also 1TB SanDisk Extreme PRO card. First noticed it after plugging it into my OLED Deck back in November. Never noticed it on my LCD Deck before and I don't think I had that one on SteamOS 3.5 yet.

I updated an LCD deck to 3.5 today and it started happening 2 restarts later

[bertogg]

So, to confirm:

• It happens with both LCD and OLED versions
• It only seems to happen with SanDisk microSD cards (people have mentioned several models, from 256GB to 1TB)
• It happens with SteamOS 3.5 but not with earlier versions

No one had this problem with SteamOS 3.4, is that right?

[roblevine]

Assuming SteamOS 3.5 is what the OLED shipped with originally (which I'm pretty sure is correct), then yes - this is my experience. Never got it on the LCD which I think had 3.4 on it. I no longer have the LCD with which to test 3.5 upgrade.

[bertogg]

FYI I'm been having a look at this issue with some of the exact SD card models mentioned here in both the LCD and OLED units. However I haven't been able to reproduce the problem so far.

For those of you having the problem:

• Can you reproduce it easily by e.g. putting the deck to sleep back and forth a few times in a row?
• How often does it happen? (daily, weekly, ...)?
• Did you modify the root filesystem or are you running a standard 3.5.7 image?

So I just started my Deck again and it immediately happend (showing SD card icon in the top bar, SD032 30,6MB). Re-inserted SD card and everything was fine again. Putting it to sleep and waking it up doesn't seem to trigger this (did it around 10 times). I then just shut it down 4 times and now I'm greeted by the SD card icon again. I'm using CryoUtilities if that matters.

[bertogg]

Ok, I finally managed to reproduce it, let's see what I find out.

[ffrasisti]

I hope this gets fixed. I can only solve it by using samsung but they just dont sell 1tb cards amd i already own 3 1tb premium sd cards for my 3 decks and they are all sandisk :(It all worked before 3.5

[bertogg]

I have everything that I need now and a couple of ideas to try to solve this, I'll come back when I have news. Thanks.

[bertogg]

Update: I have the fix for this and I confirm that it works, I'll let you know when it's available for testing. Thanks for your patience!

[ffrasisti]

Yay. Thanks!

[bertogg]

Quick question: when this problem happens the card appears as if it only had 30.6 MB. Does anyone see a different size?

If you do, please write a comment here because I would like to know more details. If you always see 30.6 MB when the problem happens you can ignore this message.

[ffrasisti]

My screenshots of the issue show that number. Ill turn on my decks when i get home and check but if irrc thats the number. Can you share why this happens in laymans terms? Thanks beto!

[geeksville]

@bertogg see bug #1408 (and the comments inside it) - that bug has a failure but the correct size for the device. So a different case. Good luck - best wishes on your efforts.

[Graubock]

@bertogg is there already a fix for that SD Card issue soon in Place? Thanks

[bertogg]

@Graubock yes, as I said in an earlier comment I'll let you know when it's available for testing.

[ffrasisti]

@betogg. Thank you! Can you give a quick overview of why this was happening?
