I had to replace my Storm a few days ago due to a faulty speaker and the replacement Storm would not connect to my computer as an additional drive. It would connect thru DM and BBSAK just fine, but I could not access info on the SD Card. Went back to the store w/my laptop and 2 more FRU's would not work BUT 5 other Blackberry's as well as the techs would connect just fine. Long story short, a tech from RIM sent us this link, View Document and as soon as I ran it my Storm worked just fine. FYI, this problem happened on 220.127.116.11, 18.104.22.168 as well as 22.214.171.124H reguardless of how it was installed/wiped etc. I hope this can help anyone if they are experiencing this issue.
