@kok00 If you formatted the card in Windows, then the contents are gone - you need to start by flashing a new image. What exactly do you see in the retropie drive ?

[kok00]

@mitu
All its contents
Roms
Other folders I can read write on.
Because I can se the drive something is happening to the USB sdcard like mounting it and leaving it in that state always.

Normally when I use to plug USB I can se only one drive with 30mb or more in size only but I have retropie drive showing up even I format the sdcard in USB and flash it.

Can it be the drivers in windows when I installed Ext2Fsd
I clicked mount button once.
How do I undo it.

What's the error you're getting when booting with your sd card on the Pi ?

[kok00]

@mitu red light only no green light.
I flashed this image before it works.
I think I messed up using Ext2Fsd

[kok00]

What do you think of this will try when I get home
Read the comments to.

Save your ROMS - using Ext2Fsd or otherwise - and re-image, then don't use Ext2Fsd.

@mitu thanks my roms all backed up way before.
I have 2 sandisk and still get red light no green.
The video I posted above not tested yet will try it when i get home.

It's only one month since i bought it

ok based on this schematics
https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/rpi_SCH_3bplus_1p0_reduced.pdf

i have found the culprit.

U8 chip leg 8 providing 3v3 volts to the board.
this ic is blown.

and if you check
STATUS
"ACT" LED
or
STATUS_LED_G in shematics you will se it needs 3v3 and comes from 3v3 line.
since 3v3 is blown or low voltage it will not boot.

check u11 pin5
