SD card mounted as read only issue (solved)

shaked · 2021-08-16 11:13:54

recently i bought an SD card for my laptop however it is automatically mounted as read only
: mount: /run/media/shaked: WARNING: source write-protected, mounted read-only.
the issue seems to be disk ownership however i still cant write on the disk after adding my user to the disk group and changing disk ownership to my user
checking disk ownership:

ls -l /dev/mmcblk0p1

brw-rw---- 1 shaked disk 179, 1 Aug 16 14:01 /dev/mmcblk0p1

trying to format the disk:

mkfs -t ext4 /dev/mmcblk0p1
mke2fs 1.46.3 (27-Jul-2021)
/dev/mmcblk0p1 contains a exfat file system
Proceed anyway? (y,N) y
/dev/mmcblk0p1: Read-only file system while setting up superblock

* the physical switch is on open

The physical switch on the card is just a nice suggestion for the reader - the logic as well as the restrictions are implemented there.
This has nothing to do w/ the filesystem or system permissions.

Make sure the switch is really, fully open. Then check again. If it's stll open, we need to know the model of your card reader (it'll likely show up in "lspci" or "lsusb") and you can also google for it, there might be some quirks (kernel parameters) required to make it behave.

is it a driver issue then?

Please use code tags, https://bbs.archlinux.org/help.php#bbcode

-> Bus 001 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller

This is your card reader, the "memory controller" (assuming you meant that) is something different.

is it a driver issue then?

We don't know yet

Do you have https://aur.archlinux.org/packages/rts5139-dkms/ ?
https://github.com/asymingt/rts5139 has a pattern that you can look for in your dmesg ("tuning execution failed")

shaked · 2021-08-16 15:42:55

tried to install the dkms but it required linux-headers went to pacman -S it but it seems network manager is giving me problems like usual maybe this should be addressed in another post... as soon as i can i will try (writing this on my laptop although NM shows 0bit upstream downstream)

seth · 2021-08-16 15:49:16

The typical network problem is that you run concurrent managers:

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

shaked · 2021-08-18 16:31:39

after installing the dkms the partitions name changed from mmcblk0p1 to sdb1 but it is still read only as i cant format it in gparted without libparted error cant write to /dev/sdb1 because its opened read only

Do you have other cards to test in that reader and another reader to test that card in?
Is the card SD, SDHC, SDXC or SDUC?
The backward compatibility is not guaranteed and given the age of the reader, it'll probably not handle SDUC and only maybe SDXC - r/o interpretation could be a safety measure by the reader out of concern to damage the card on writing attempts.

shaked · 2021-08-18 20:10:37

i was sure i posted a reply here but i don't see it the card is SDXC on an unofficial (because lenovo is lazy unlike intel) it was written it supports SDXC cards but no mention on capacity my card is 128gb the minimum for the SDXC specification is 32gb if that is the case and it is a hardware support issue the sd card will just need to wait until i get a new laptop the store i bought it from doesn't take kindly to returns after opening the package

seth · 2021-08-18 20:42:26

The forum is having a bad time, https://bbs.archlinux.org/viewtopic.php?id=268887

You can get compact sdxc usb 3.0 card readers for $10-20 on amazon.
Ideally you'd test a different card/reader w/o investment, though (older sdhc card to make sure the reader & driver principally work and maybe a friend/coworker/family member can test the card in a different reader)

shaked · 2021-08-18 21:39:30

i dont think my laptop is even usb 2.1 10-20 dollars is around the same amazon price for the sd card itself which after taxes import fees & retail its around 60$ i took it to the store a day after i got it and an employee showed me that it works on his laptop i think it would be better to sell it and get some money back

Your laptop disagrees

https://www.google.com/search?q=%22rts5 … %22sdxc%22 has quite some hits, but https://www.insanelymac.com/forum/topic … for-macos/ suggests that he can write on "a" 128GB card fine (but this is a mac driver - we're talking about HW limitations)
https://aur.archlinux.org/packages/rts5139-dkms/ has some module parameters

modinfo rts5139

Disabling "selective suspend" (and other power management stuff) might get you somewhere…
https://wiki.archlinux.org/title/Kernel … le_options

which after taxes import fees & retail its around 60$

It's completely off-topic, but there's a massive tech center in Haifa - are you sure your access to casual consumer tech (amazon imports aside) is this pricy?

modinfo prints the module poperties and available parameters, to see what's actually used (it the module exposes that) check

systool -vm rts5139

In order to make "modprobe rts5139 selective_suspend=0" do anything, you'll first have to unload the module (modprobe -r)

shaked · 2021-08-19 12:44:29

it doesnt seem the parameters are enabled

But it /is/ disabled ("0") and I have little hope that enabling would improve anything here

ok thank you very much for helping me with the issue/s i learned to use the forum effectively and some new commands coming from linux mint so it is a big deal

James_Bourbon · 2025-01-06 01:28:25

I too have the same issue. This is when using a MicroSDXC card directly into the side of a Dell laptop, which is regardless of the file format. Yes, I have tried each format one after another for testing. No, this card is not in the standard MicroSD card holder with the locking slider switch. Ironically, this MicroSDXC card is easily read by Mint and allows Read/Write access.

In Arch, it will assign root as the owner and not allow any users write access. You also cannot change the access. Strange, I know... However, I have found a workaround! Using the MicroSDXC card in an "unlocked" MicroSD adapter while in a USB-to-MicroSD card reader WILL allow the device to mount into Arch with user permissions! For some reason, Arch does not automatically mount MicroSDXC cards with user permissions for laptops that have those slots. It treats it as if the card is locked. Using the USB adapter will allow the card to be mounted and written to without any issues.

what a call from the past thanks for sharing your fix.

seth · 2025-01-06 11:33:42

The fix sidesteps the problem by not using the problematic adapter.
@James_Bourbon, you're also using rts5139 w/ the same output as in #17? Or "just" the rtsx modules?
If you still have access to the mint system, does it use the same kernel module and what do the parameters look like there?
