This is kind of scary... HC is the standard way to make and sell SD cards now, and "regular" non-HC cards are getting harder to come by.

@JoelCoehoorn Yes, bad choice of the printer developer to choose for the old format. I'm just the messenger, it is an official statement release from the printer OEM.

<p>I was having problems formatting micro SD cards for my Monoprice Mini v2. I have some 256 MB cards tried formatting them FAT FAT32 etc, no luck.</p>

<p>Then I downloaded a program called <a href="https://www.sdcard.org/downloads/formatter/" rel="nofollow noreferrer">SD Memory Card Formatter</a> did the format on the card with this and the card is now readable in the printer.</p>

# How to format an SD card for Monoprice Select Mini V2?

(Asked by: username_0 on 2019-01-02)

I bought a 32 GB SDHC (Sandisk) I'd like to use for my Monoprice 3D printer.  
I have downloaded Partition Wizard and partitioned a 2GB primary partition formatted as FAT and it still does not show any files.

What am I doing wrong?

For an SD card to work with the printer firmware [Monoprice suggests to format the SD card to FAT32](https://monopricesupport.kayako.com/article/59-why-is-my-printer-not-reading-my-sd-card).

However, the Monoprice Select Mini V2 is not able to read SDHC memory cards, it is advised to use an SD card (smaller than 4 GB) instead.

According to the [Monoprice support website](https://monopricesupport.kayako.com/): ["Why is my printer not reading my SD card?"](https://monopricesupport.kayako.com/article/59-why-is-my-printer-not-reading-my-sd-card):
