I just ran into something similar with 4G cards, where the nanobsd numbers for 4G sandisk cards were wrong.
It looks like in these most recent cards, Sandisk has reserved more flash for wear leveling and spare sectors, so a 4G nanobsd image won't fit onto a 4G card. I used the numbers from fdisk to calculate the new device size, and used that in my nanobsd script, and all was well. You're getting errors at the 3.9G boundary. You may be running off the end of the device. - Robert On 1/24/11 6:41 PM, Mike Tancsa wrote: > On the latest SANDisk batch of CFs I got, I am getting periodic errors > reading from the flash on my 5501 (FreeBSD RELENG_8).
