Comment(by davidpfarrell):

 I have never been able to successfully install an SD card into my new OLPC
 (Just arrived on 12/20).

 I get the errors mentioned in the ticket description every time.

 The first time I plugged the card in, I pushed it as far as it would go,
 but it did not feel like it was completely in - But again it would not
 insert any farther.  There was no spring-click feeling that you usually
 get when inserting an SD card into slots.

 The card did not register in the Journal.

 After spending a minute or two carefully prying it out, I tried inserting
 it again.

 This time I was able to insert it further and get the satisfying lock-
 click.

 But the card never seemed to register in the Journal.

 I then discovered this page:

 http://wiki.laptop.org/go/Tests/SD_card

 Switching to the console and checking dmesg showed errors similar to the
 one in the ticket description.

 After several failed inserts, I then tried with a different SD card, which
 also failed.

 NOTE: Both SD cards are SanDisk 2gb, one being standard & the other being
 UltraII - Purchased at different times from different places.

 As the error messages seem to indicate bad blocks, I decided to reformat
 the SD card.  I formatted it in WinXP Pro SP2 using the FAT filesystem
 (which is what it was formatted when I purchased it)

 This did not help.

 It is only in writing this message that I realize that my first insert,
 which did not act normally, might have initiated the problem. I've not had
 as much trouble removing the card as I did that first time, either.

 Any advice would be appreciated.
