Hello all, I set-up my E220 camera with a 32gb Kingston sd card. Sometime later the camera was upgraded with a 64gb sd card.
For some reason the sd card I removed (32gb Kingston) will not format. I have tried formatting using Windows 1 1 Disk Management, MS diskpart and Linux but nothing will format it. Can anybody throw any light on why the sd card will not format

Thank you

Sometimes SD cards just fail out of the blue or you notice strange playback behavior like recording freezing or skipping.
If formatting fails there’s an issue with the SD card. Corrupt or bad file systems.

When you were in Diskpart and selected the SD card volume, did you enter clear all
and then try to format the card?

You could try doing this a shot…

Press the Windows Key and type cmd.

Right-click on Command Prompt and select Run as administrator.

In the prompt, type chkdsk X: /f (Replace X with the exact drive letter of your SD card).

Press Enter. Windows will scan and attempt to fix file system errors.

If that succeeds well you might be able to format it after works.

Hi jd164 thank you for your response

DISKPART clean reports…succeeded in cleaning the disk (but will not format)
DISKPART clean all reports…succeeded in cleaning the disk (but will not format)
DISKPART chkdsk F: /f does nothing, but at one time it reported RAW some thing disk

Having I spent time googling the subject it would appear sd cards formatted by eufy E220 cameras get encrypted during the ext4 formatting processes, obviously for security reasons. This is why I cannot format this 32GB Kingston sd card
Perhaps there should be two options offered when formatting sd cards in the eufy camera.
Format with encryption for security.
Format without encryption but with a security warning. Then the sd card could be reused in other devices

Well its goodbye to Kingston sd card its in the bin.

RIP

One more snippet of information, this Kingston sd card is not readable in a Windows machine because EXT4 format, but in Linux your can view all the contents of the card and copy the contents to the Linux machine. Having said that Linux would not format it.
