How to I wipe the eMMC

AndyFraser

I am trying to install trueNAS onto the eMMC on my ME Mini but I am getting the error “Failed to find partition number 2 on mmcblk0”.
I am wondering if this is because Windows 11 is installed on it.
So, how to I wipe the eMMC completely?

Hi there, here is the tutorial https://url.bee-link.cn/uRVH

support1 This doesn’t help, the document instructions are for installing to another ssd, not to the internal emmc which is giving an error.

Hi !
I have exactly the same problem with the same error message. And I strictly followed the instructions for the installation of TrueNAS.
Is the anything to do in the BIOS or the disk manager in Windows 11 ?
Thanks !

PS : I saw a curious manipulation on YouTube :
Is it necessary ?

We will test if truenas can be installed on EMMC . We will keep you updated

After testing on our end, we’ve confirmed that the same problem can occur initially, but we successfully installed the system on the eMMC on our second attempt.
Could you please try a second installation? This often helps bypass the issue, and we hope it will work smoothly for you as well.
If you still run into trouble after the second attempt, feel free to let us know—we’ll be happy to provide further assistance.

Hello there!

I had the same issue when attempting to install TrueNAS on the eMMC drive.

It took me 4 installation attempts one after the other with no reboots. Eventually it correctly partitioned and formatted the drive. Just be patient and keep trying - eventually the installation will complete.
I also tried a second time just to check and again it took a few attempts (3 on this occasion). I have heard that multiple attermpts are required due to eMMC being very slow to present partitions to the O/S (up to 30 seconds or so). This may be hearsay but it seems to be accurate.
