Cannot boot from Sandisk Ultra 8GB

[Lamer]

Hello, I am very new to Raspberry Pi and I have bought myself a Sandisk Ultra 8GB 30MB/S SD-card (SDSDU-008G) to use on it. I have installed RaspBMC on the card, but it will not boot. Does anyone know of other distros that will work or do I have to return it to the shop. I already have a Sandisk 4GB with RaspBMC which works fine, but I think it's a little slow at some times and I thought that a bigger and faster SD-card would improve the performance.

How did you make the new SDcard?
Is it a fresh install or a clone of your 4GB card (with the filesystem expanded to use the extra 4GB)?

I downloaded the RaspBMC image, formatted the SD-card with SDFormatter (I've played with the options here, tried turning on/off format size adjustment etc.) and finally extracted the image with Win32DiskImager. I have also tried formatting the card in Windows with FAT and then go straight to extracting the image without using SDFormatter. The downloaded RaspBMC has no CRC-errors since I've successfully extraced it to another (slower and smaller) SD-card and made it boot. For some reason I have begun suspecting that maybe the RaspBMC might just not work with this particular card and an other distro would be better. Yes, it's a fresh install and not a copy of the previous one - thanks for pointing that out.

which program are you using to unzip the file and have you tried a different image mirror

As mentioned in previous post, the image has successfully been tested on another SD-card. The image was extracted to .IMG with WinRar.

There has been a booting problem with SanDisk Ultra cards which came to light during early testing of NOOBS 1.3.x . This was solved and fixed in NOOBS 1.3.2 It's possible that this is now "re-appearing" with Raspbmc *img's. I suggest you re-format the card with the SDA Formatter using FULL(Overwrite) and FORMAT SIZE ADJUSTMENT ON modes and then download and unzip NOOBS 1.3.2 onto the card (possibly using an external USB card reader/writer if your computer is more than ~ 3 years old). NOOBS can then be used to install a version of Raspbmc which should boot O.K.

Thank you very much, sir! That did the trick. I now have RaspBMC installed on my new 8GB Class 10 SD-card. The performance is much better than with the old 4GB as i anticipated. Thanks to everyone contributing with solutions.
