Help! Upgrading micro SD from 8 GB to 64 GB on B+ model

[spawnsworth]

Hi all,

I hope someone can help me out here as this is killing me! Apologies if this is in the wrong section but I think it's just about relevant that I post this in here. I've Googled left right and centre but not having any joy thus far.

So, I have an 8 GB micro SD card which a started off by using the latest Retro Pie 2.3 image. All absolutely fine. I've tweaked and configured things, added ROMs etc and now I would like to upgrade this to a 64 GB card but I don't want to undo all the work that I've done by starting from scratch (no raspi pun intended),

So, I thought it would be as simple as taking a backup image of my current 8 GB SD card with Win32DiskImager then writing this to my new FAT 32 partition 64 GB micro SD card.

The new card is a Samsung Evo 64 GB micro SD (apparently it is genuine original but I have my doubts). I know lower capacity Samsung SD cards work fine since these were shipped with Raspi Pis I recently order for work (think they were 8 GB variants).

But I've had nothing but pain getting this to work. Perhaps the SD card is simply not compatible but I want to cover every angle to make sure this is the case.

When I write the 8 GB image using Win32DiskImager it appears to show the boot and file partitions when I browse this on my Windows 7 Laptop using Paragon EXT3 reader software. It looks absolutely identical to the 8 GB card that works, but when I put this in the Pi and fire it up I get absolutely nothing. The Pi doesn't even think about booting and the screen remains blank.

I was hoping that it it did boot then I would expand the disk using raspi-config and that would be that but this is turning out to be somewhat more difficult than I anticipated.

I would much prefer not to have to buy another new Micro SD but if that's my only option then I'll go with that. So my options are limited to:

1) Plug the micro sd card in to a USB card reader, then in to the Pi (I can see all the files as they are on the 8 GB card). Then rsync the files from the 8 GB card to the 64 GB card in case some stuff hasn't written properly.

2) Bin the whole thing, use the 64 GB SD card for something else and buy a new one. If so, can anyone recommend a 64 GB Micro SD that is fully 100% compatible with the Raspi Pi B+?

Really hope someone can help me as I've spent a stupid amount of time trying to get this to work!

Thanks!

I vote for the first optio. USB micro SD reader is a must to have. Also you can try use it as an typical USB disk and boot (mount your root partition) from it.

Have you tried putting Raspi on the 64G card to see if that boots?

I haven't tried with a new raspian install but I did retry the original retro pie image and no joy.

Anyone got the actual full commands I need to synch the partitions from the SD card to the USB reader (with the 64 GB card)?

I just get the impression that a fresh Raspian install onnthe 64gb would give me the same problem.

If it's just easier to pick another card then I'm happy with that but just need to know for certain that it'll work OK if poss!

Thanks

things to try

1) make one fat32 partition
download h2testw 1.4 on a windows box and test that on the SD card

2) burn latest raspbian onto the SD card and see if it boots on the RPi

3) partition it up to a fat32 and linux partition and copy the partitions over from your old 8GB one

Thanks for the suggestions so far guys really appreciate it!

If I go with option 3. What are the exact steps I need to take to achieve this? I would guess:

1) Format 64 GB SD card to Fat32 using SDFormatter for Windows.
2) Insert 64 GB in to USB reader, then insert reader in to Pi. Boot Pi.
3) Copy partitions from 8 GB card to 64 GB card (USB reader). What are the exact commands I need to use?

I've been working on Linux for several years but never really understood how the partioning works. I've never really needed to either to be fair.

I currently have an 8 GB image installed on my 64 GB card but it just won't boot but I can see all files when plugged in to USB reader so can I just rsynch everything from one device to the other? It is showing a 56 MB and 7.26 GB partition for each device. I'll provide a df -h output when I get home if that helps!

Just really keen to nail this. I'd just get a proper 64 GB card that is fully compatible if that helps. Has anyone else managed to get a 64 GB card working on the B+ and if so, what card and did it just work out of the box?

Cheers!

I'd run the h2testw just to make sure it is not a fake
then
look at
http://www.raspberrypi.org/forums/viewt ... 14#p122476 to see how to copy stuff over to a new drive [sd card etc]

[spawnsworth]

Currently running the h2testw test. It's going to take another 32 hours to complete apparently. Do I need to test the full card to prove if it's a fake? There is an option to test X no. of megabytes.

Cheers

Some have had issues even with legit Samsung EVOs. I don't know if it is still the case. Newer firmware may have fixed things by now.

Hi I'm also struggling with this card (Samsung Evo 64gb)...

I've tried to upgrade from my 16gb card which I'm using on a Raspberry Pi 3.

I've cloned with both dd and tried Windows Win32 Disk Imager to clone my 16gb sd to the samsung Evo 64.

It clones over fine but then I get problems on boot. Messages about blk_update_request i/o error, dev mmcblk0 data blocks 200 - -error and such.

Then when I fsck all the partitions and fix issues on the samsung card and try again it nearly boots but then freezes with the cursor blinking.

Has anybody else ever managed to clone to this card in order to upgrade? Thanks for any help.
