8Gb SD card seen as only 4Gb
by Completely Clueless from LinuxQuestions.org on (#593R5)
Hi all,
I'd run out of free space with the SD card I'd been using in my Pi. That card was 4Gb, so I decided to replace it with an 8Gb one. I dd'd the old card's contents over onto the new one and inserted it, expecting to have everything up and running with an extra 4Gb of free space, but the OS reports the new card as still only being 4Gb in total size. I'm no techie, so the best reason I can come up with to explain this is that Linux doesn't check the actual size of SD cards, it just relies on reading the partition table and since I used dd I'm guessing I've copied over the old partition table which tells the OS the card is 4Gb when it's actually 8Gb. Would that be right? If so, can I correct the error by editing the PT on the new card?
Thanks.
