Problem initializing 32GB Samsung Evo Plus microSD card

[aperezbios]

I have a 32GB Samsung Evo Plus microSD card, MPN MB-MC32G, which both the ZuluIDE AND ZuluSCSI RP2040 fails to successfully initialize. Under synthetic load on my PC, in a generic USB 2.0 to SD adapter, it works fine. Since this is a currently-manufactured SD card that is widely available through retail channels, we need to figure out what's going on here. I'll have Morio see if he can't figure out what's going on with this card on the ZuluSCSI side, and report back.

This output was collected via the USB UART:

Ok. I ordered this card, it should arrive in about a week.

[PetteriAimonen]

As a datapoint, I happened to have the 64GB version MB-MC64G but it initializes fine for me.

[PetteriAimonen]

@morio As a first step, I would try to figure out why it is trying to read sector 0xFFFFFFFF. Probably a "-1" but where it comes from. That the sector read fails is no surprise.

Could also be some kind of filesystem issue.

[PetteriAimonen]

Only local supplier with this card in stock turned out to not have it in stock.

@aperezbios Could you take a dump of the beginning of the card? This will let me check for any partition and filesystem issues.
On linux something like:

dd if=/dev/sdx of=sd_card.bin bs=1M count=16

[PetteriAimonen]

Hmm, the MB-MC32G card I ordered finally arrived, but apparently it has been sold before and returned by a customer.
Thus it is not in stock condition and does not reproduce the problem.
