I've just got my first Raspberry Pi 4. I'm trying to install Raspbian's July 2019 version. I've read all related issues to this problem here and I can´t manage to find the problem.
I downloaded Raspbian with desktop from the official page: https://www.raspberrypi.org/downloads/raspbian/ And flashed it on my Kingston 32 gb Class 10 SD Card using balenaEtcher.
The first incovenient I got was the write speed I got while using balenaEtcher: between 600 and 800 kbps. When the flash finished "succesfully", a tiny warning, hidden under a red X said:
\.\PhysicalDrive1: Source and Destination checksums do not match
I didn't pay attention to this warning and proceeded to turn on my Pi anyway, and then I got the error in the title:
Kernel panic-not syncing: VFS: unable to mount root fs on unknown-block(179,2)
Reading other issues here, I tried editing cmdline.text by changing the rootfs and replace the 2 at the end with a 6, but this made my Pi stuck at the four raspberries without booting.
I also tried doing a filesystem check with fsck.ext4 on my PC with Linux mint but I got a message that said that the filesystem couldn't be found.
I think that the SD Card may be the problem but I just want to make sure it is before buying a new one, as they are not cheap where I live.
I don't know what else I can do. Thanks for your help.
Already run an H2testw, here we have the results:

The media is likely to be defective. 87.0 MByte OK (178293 sectors) 30.0 GByte DATA LOST (63041419 sectors) Details:36.5 KByte overwritten (73 sectors) 0.5 KByte slightly changed (< 8 bit/sector, 1 sector) 30.0 GByte corrupted (63041345 sectors) 36.5 KByte aliased memory (73 sectors) First error at offset: 0x0000000002f41010 Expected: 0x5899e01398821110 Found: 0x5899e01398821510 H2testw version 1.3 Writing speed: 7.95 MByte/s Reading speed: 9.72 MByte/s H2testw v1.4
Don't need to make any more clarifications, already bought a new card, thanks for your time.
