Tue Feb 24, 2015 12:43 pm

Hi,

I just bought a Raspberry Pi B+.
I can to buy a 4GB micro SD card Class 4, or 4 GB or 8 GB micro SD card Class 10.
So, can I uses 'Class 10 micro SD card' to set up on it a NOOBS ?

8GB Class 4 or 6 is adequate for NOOBS

Does it matter which brand of micro SD card is used?

It just needs to be 11mm * 15mm so it fits the slot. :roll: :roll: :roll:
With an older Raspberry Pi you need one that's 32mm * 24mm or an adapter for the tiny one.

Well, I just bought a Kingston 8GB Class 10 microSD card.
When I plug it into my laptop ( Arch linux installed on the laptop ) I get error messages on the virtual console:
mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0x0

What does it mean?

That's an I/O error.
It means the SDCard may be trash. It may be a fake.

It needs reformatting and re-writing.

I'm trying to format it with Gparted but can't.
I always get the error: I/O error during read on /dev/mmcblk0
/dev/mmcblk0: unrecognised disk label

What can I do to solve this problem?

Toss it in the recycling and buy a fresh one.

Well, I went to the store where I bought the micro SD card, and there this card can be recognized by the Windows 7 operating system. So, the cause of my problem is probably that that on my laptop ( have installed Arch linux system on it ) I don't know how to setup the inbulit card reader.

Code: Select all

lspci
BCM57765/57785 MS Card Reader
BCM57765/57785 xD-Picture Card Reader
Any advices will be appreciated!

OK
I just bought another brand ( Samsung ) of micro SD card ( Class 6 ) and it works out of the box.
The previously mentioned micro SD card is Kingstone, Class 10. It is not recognized by the Arch linux system kernel.
So I can say: the problem is solved.
Mybe somebody can tell why one card works, the other does not.

I bought an USB microSD card reader and with it I can use the microSD card.
I completed partitioning and formatting microSD card.

I have now installed on it Arch linux.
I can now boot with it the RaspberryPi.

Success! :D

Thank you all for help.
