H2testw results.....

[linuxares]

hah me too that why iam so confused but all of this for sure they can lock themselves on read only even perfectly new one thats why iam avoiding patriot micro sd :

Haha happened to me at my old work. Brand spanking Sandisk, some kind of pro card. We ordered like 5 of them so it wasn't a big deal so it was just to ask the distributor for a new card and they sent it right away.

The teacher was like "But it's brand new!". I didn't want to entertain a old person not understanding that mass produced products can break before use because of <reasons>...

If anyone is interested there is a much faster way to test the capacity of the card and it can be done in minutes not hours for higher capacity SD Card like 256GB, although it seems to top out at 512GB for support.
Although H2testw is more thorough then the faster method.

3. Then run h2testw again, and see if the issue persists.

i mean the funny thing is that issue is not there on any other h2 scans (did 3 and only the first one shows errors )without chkdsk run on it

PS. Samsung sucks only kingstone or sandisk


edit: i push that chkdsk

C:\WINDOWS\system32>chkdsk /F /R /X F:
The type of the file system is FAT32.

i guess the card is fine perhaps it was just an error in first h2scan idk?

I mean, the sd card does have some logic inside of it, and when something triggered those blocks they probably got disabled by the sd card itself right? (I'm sadly not that invested in how they work)

Exactly that. chkdsk can't do shit since it doesn't have low level access to the SD card. It was the controller on the card that detected the error and swapped the bad block.

chkdsk only repairs possibily bad filesystem damage. Nothing more.

A (micro)SD will not repair bad sectors by itself. The Controller doesnt even have the ability like a SSD, which has a seperate Controller for that like doing the wear leveling.

For sure he ran some other diagnostics on Windows, like the drive repair feature which does the same, or is chkdsk with /f or /r. Or he did a full format on the card, which will remove bad sectors, too.

Chkdsk /f searches for logical Errors (filesystem)
Chkdsk /r searches also for bad sectors

So like i said I was curious about this brand and the price was good just bought the second one.

This time no bad sectors but it is pretty funny too. After partitioning it in hekate it is losing like hafl of read speed but if it has only one whole partition it works like a charm even when fully loaded lol

Now i can return them in peace
