Hi all,
I own 3 Pis, 2 original 256M versions and one new 512M version via the kickstarter project.
I have a Fedora 17 boot SD, and three 2.5" external hard disks, aim being to boot from SD card to HD.
I was today attempting to tar the latest SD image to hard disk using the new version board. It lasted from 10 secs to 1 min before falling over with IO errors, and the kernel remapped the disk from sda to sdb.
I tried this with two hubs and all three hard disks, the result was the same..
Next I swapped out the Pi for the older 256M version. Same PSU, Hub, HD etc ONLY the Pi was changed. and 2G tarred up without 1 error.
The Pi only connects to the world via on USB port to a 4 port hub with a 3A PSU in all cases.
Anyone else seen this, or have I just got a duff 512M Pi?
John
Re: New 512M version Pis - disk problems
When was there a Kickstarter for R Pi?
Anyway, on to the main topic here. There is always a chance you got a deffective unit, however, I have found that the 512 MB to be very sensitive to two things. First is overclocking, in particular overclocks to anything other than the ARM core. Second is having a good quality power supply. The power supply I used with my 256 MB models for months would cause SD card corruption with my 512.

Hi Jessie,
Firstly the kickstarter was actually for MagPi ( The Pis magazine ) http://www.kickstarter.com/projects/the ... ?ref=email
Secondly, I am a server guy, no overclocking and the PSU is the one shipped by ModMyPi (Hardware suppliers for the Kickstarter).
I also have since used a 12A lab supply, same result..

I'm going to move this thread into the troubleshooting section of the forums. Look for the copy there.
EDIT: Sorry I didn't intend to lock this thread only the original. It is now unlocked.
