Encryption Question

October 31, 2009
By

I have a USB drive which is encrypted by Credant Mobile Guardian software. I have the key for this disk.

I am unable to read the disk (I/O Error) on a computer unless CMG is installed. This means that I am not even given an opportunity to authenticate or enter the key.

Is there something I’m missing? Shouldn’t I be able to read the disk if I have the key, even on a computer which doesn’t have CMG installed?

    Perhaps something got corrupted on the drive?
    I have a 4gb SanDisk Cruzer USB drive that automatically installs temporary software onto any machine I insert the drive into so that I can copy files from the drive onto the other machine and as far as I know it automatically removes that software upon removing the drive. And no, I don’t like this. I also have an older 120mb USB drive and it doesn’t play around with any of that nonsense, thus it gets more use than the other one.

    All I can say is do as the above poster suggested, visit the site and see or RTFM. luck

    Thanks both. Don, I don’t think the drive is corrupted, it works fine on my laptop (which has CMG installed) but doesn’t work on my wife’s laptop. Funny thing is, that it used to work on both.

    Additionally, my 4GB micro SD card works fine for transferring mp3 files from laptop to phone, but that doesn’t work on her laptop, either. Both of mp3 players are unaffected by the security policies which (for this direction of transfer) require that any files moved from HDD to removable disk must first be encrypted. I just figured the encryption software would allow you to decrypt as long as you had the key. Apparently not.

    I have not ruled out the possibility that there is something wrong with her computer, because it’s been acting up lately.

    I suppose transferring files will have to be done on CD/DVD-ROM from now on. What a pain in the ass.
