MikroTik

I recently acquired a RB1100AHx4 router and I have tried two samsung pro endurance microSD cards. One 64GB and the other 32GB. Neither microSD card shows up in console

/disk print

nor Webfig system -> disks:

[admin@RB1100AHx4] > /disk print
# NAME LABEL TYPE DISK FREE SIZE
[admin@RB1100AHx4] >

I have tried what has been suggested that I saw in past forum posts:

• On a Linux machine delete SD card partition and create and format a new ext3 partition manually.
• Have RB1100AHx4 shutdown and powered off. Insert microSD card then power on RB1100AHx4.
• While MicroSD card is inserted, reboot RB1100AHx4 and check if it sees the microSD card.
• While MicroSD card is inserted, shutdown RB1100AHx4, unplug power, and then reconnect power.

It came with RouterOS v6.45.9 and after trying the steps above then updated to latest long term release v6.47.9. Retried above steps (besides reformatting the cards).

I've ran out of ideas.

It doesn't make sense how difficult it is to get RouterOS to recognize microSD cards considering it is a Linux system and sd/mmc isn't exactly complicated and comes with vanilla Linux kernel. I would know as I've written device drivers for 4-bit SD and 1-bit SPI mode for Linux and custom RTOS embedded systems myself.

I have the RB1100AhX4 (not the Dude edition) and having problems with the MicroSD card. I tried just about everything I see other people tried and nothing. The RB will not detect the SD card. I formatted in ext3 and nothing, in fat32 nothing happens. I tried 4 different SD cards, a 4Gig, a 16Gig a 32Gig and a 64Gig too. Not is detected. It is like the SD slot is dead. I have the 1100AhX4 for 4 years now and never needed to use the SD slot before. Now I tried every way possible and it appears to be dead. Am I missing something? I have all the packages installed thinking that there might be a package that was missing. Please if someone has any ideas I would appreciate it! Thank you all in advance!

I have this issue on a CCR1009, reported in SUP-81653.
Looks like this is known to Mikrotik, but they did not bother to fix it, yet.

Finally I got an SD Micro to work. I formatted on a Canon Camera and it still did not work. But after I rebooted the Router at 3:30 am, it recognized the SD card. It is a pain in the ass trying so hard to make it work for several days.
Anyway, Now I can use any card any name, any brand any size like 16, 32 and 64Gig. They all show in /disk print. Strange things happen!

I guess I was too quick to make a comment. After 2-3 days it stopped working again. I repeated the same steps but nothing again. The same cards that worked before, refuse to be detected. It is annoying to say the least. I hope Mikrotik, a very reputable company to fix this problem soon.!

It is unfortunate that Mikrotik chose the absolute Silence in my support request sent on July 23, 2022. I sent them a Supout.rif file that they requested and still 30 plus day they have not replied.
I was even thinking about buying another Mikrotik device RB1100AhX4 the Dude Edition, but after such a disregard to my request, I will have no choice but to look elsewhere for an alternative router. I have been working with Mikrotik for over 15 years now and I hate to have to change Routers and other Mikrotik devices to another brand.

Too bad.

I think can be an hardware problem.
I have some devices with sd card (king—) and I have problem just with one after some years of wirting.
Usually I wipe out completely the sd using the official "SD Card Formatter" of SD Association.
Some SD are not recognized if formatted before from a phone, a gopro, or another device that do not create "so" standard file system...
After the SD is correctly recognized, you can format it inside RouterOS on what fs you like.
