Using a password protected SD card is a great way to ensure software security and/or to make sure your TS-7000 SBC based product cannot be used in an unintended matter once deployed. Technologic Systems has developed a Linux application named 'sdlock' which can be used to manipulate SD card hardware-enforced password locks and set the card's permanent write-protect feature. The SD Card can be locked to a specific device using a password.Īn SD card can be locked using a password, or it can be set to permanent write protected mode.Īlso the manufacturer of an SD card may not include the secure features in their cards (which would probably mean it wouldn't work on these phones) I'm sure they'll sell you an app to do that though.

Preventing you from using it to move data between your phone and anything else. I expect this problem is coming up because when you stick in a new unlocked SD card, MS flips all the switches to turn on the DRM on the card, effectively bricking it for any device short of that specific phone you put it in. There's a reason it's called a ' secure digital' card. the SD card format (sony iirc?) has a lot of cloak-and-dagger DRM features built into it, that up until now haven't gotten used much. Slipping a little bit more towards on topic though. You can piss and moan all you want, but be sure to Vote with your wallet - it's the only vote they count. It's like those game consoles that can take a hard drive upgrade, but only if they get to dip their hand into your wallet during the upgrade, selling you an 'upgrade kit' that gets you past their clandestine restrictions on swapping of hardware. Who else in the world would consider making a proprietary format of SD card? At twice the price I'm sure, 'for the added quality' of course.

That, and it doesn't even surprise me in the slightest that MS is going to require you to buy an SD card from THEM.

In this phone, the SD card it not a user serviceable part. The only reason it uses an SD card is because it's convenient to build, and it allows the different providers to use whatever size storage they want.
