I am experiencing a problem with using Bitlocker To Go on an SD card, when the bitlocked card is accessed from an SD card slot on my Toshiba netbook. The problem is that if the SD card is not "ejected" via the Windows Explorer menu button, two issues occur: - Windows will not mount any external drives, either in the SD card slot or USB ports -- not even the same bitlocked card upon reinsertion into the card reader, until the system is restarted. - Windows will not shut down, and simply hangs at the "shutting down" screen, requiring a hard reset with the power button. The netbook is an NB200 which has a built-in SD card reader slot, as well as 3 USB ports. It is running Windows 7 Ultimate 32-bit. The system drive itself is not bitlocked. The SD card has been successfully encrypted on the netbook with Bitlocker To Go, and accessed on both the netbook and a Windows 7 Ultimate 64-bit desktop. I am aware of a separate issue where bitlocking the system drive can cause problems with shutting down a PC, but the hotfix for that isn't applicable here (it literally cannot be applied because the system drive is not bitlocked). Is this a known issue? Obviously the workaround is to always eject the SD card using the "eject" button in Explorer, but this can be easily forgotten. Because the SD card reader is built in to the laptop, no "safely remove hardware and eject media" appears when the SD card is inserted. There is no "policies" tab in the SD card or reader properties that would allow me to "optimise for quick removal". It is a considerable inconvenience in using Bitlocker To Go, so I'd appreciate any advice. Thanks.

Hi, Thanks for the post! According to your description, the SD card and USB ports cannot be used unless you choose to “eject”. Firstly, please update the SD card driver and the BIOS to the latest one. Then, I would like to clarify more details to troubleshoot the issue. 1. Enter into Safe Mode to check if it happens. 2. Using Pormon tool to narrow down the problem, it can help you check how applications use ports.

Hi, thanks for your reply and sorry I've been too busy to follow the steps you recommended. I will do asap, and then report back. Thanks again for taking the time to post!

Hello again, The solution was, as you suggested, to update the driver. For any future users who find this thread: whilst the SD card reader seemed to work fine without manually installing a driver, manually installing the "Card Reader Controller" package from the Toshiba website activated the "safely remove media" taskbar icon for SD cards, and also the "policies" tab for the SD card in device manager. Having made sure that the SD card is "optimised for quick removal", the problem I described earlier is now fully resolved. Thanks again, and sorry it took so long for me to follow this up.
