I already tried the TrueCrypt forums but they dont seem to be that active so hopefully you guys can help...

So here's the deal. I have a 1.5TB external hard drive (with one (1) 1.5TB partition) that was/still is encrypted using Windows Bitlocker. Everything was working great. I wanted to also use TrueCrypt encryption on top of Bitlocker so I attempted to encrypt the same drive/volume with TrueCrypt. Everything was going great for the 36+ plus hours it was taking to encrypt the data, but then at 99.744% TrueCrypt gave an error of "The Media is write protected" and will not continue. Everything I try to do to fix the drive will not work.

I believe the problem is Bitlocker, while I can still unlock the drive it will not let me turn it off and gives me a "The parameter is incorrect" error when I try. As i said, I can unlock the drive, but can view the files.

As a little test I created a new partition on a separate drive of 1GB to try to replicate my findings and the the same thing happened. I turned on Bitlocker and ran the TrueCrypt encryption which errored out at ~32%. I deleted that partition and reset it up, left Bitlocker off and ran the TrueCrypt Encryption and it was successful.

So here is the question, How do I either turn off the Bitlocker so Truecrypt can finish or how do I backtrack the 99.744% that TrueCrypt already finished so I save the data and start from scratch?

I am running Windows 7 x64 if that matters.

If i can provide further details just let me know.

Any help would be greatly appreciated.

"I wanted to also use TrueCrypt encryption on top of Bitlocker"

:blink: WTF???

WIPE it and restore your files from backup, since this is external drive I would assume its your backup so should be no loss.

Where did you get the idea that it would be ok to use 2 whole drive encryption methods? Using a virtual encrypted disk should be fine - but whole drive.. no its pointless for one and second how do you think it would work?

As to backing out - I don't think you can, as to finishing - again I don't think its possible.

You will clearly see on the encryption removal instructions

http://www.truecrypt.org/docs/removing-encryption

Move all files from the TrueCrypt volume to any location outside the TrueCrypt volume (note that the files will be decrypted on the fly).

WARNING: Before you continue, make sure you have selected the correct device, as all files stored on it will be lost. The 'New Partition Wizard' or 'New Simple Volume Wizard' window should appear now; follow its instructions to create a new partition on the device. After the partition is created, it will no longer be required to mount the device with TrueCrypt to be able to save or load files to/from the device.

I badly need help. I've had a look around the internet for a while now trying to find a solution.

I recently encrypted my 1 TB Seagate HDD with BitLocker but it didn't work on XP so i removed the password and started encrypting it with TrueCrypt.

And at 62.318% it says "The media is write protected" =(

It has very important files on it which i don't want to lose... if there's ANY way to finish ecrypting and/or cancel TrueCrypt so i can access my files again, it would be much apprieciated. also, i did not make a backup of my files which i know was very stupid and foolish of me now..

So bitlocker will work on XP for read with the bitlocker reader.

But let me get this right, you started encryption of a disk that had your only copy of critical files on it??

C'mon Dude! Really??? Sorry but I would have to assume your just dicked - just start over and restore you files from your backup. What you don't have a backup of your important files you don't want to loose??

Bitlocker Reader didn't work for XP (i couldn't install it)

and i didn't back it up because i didn't have any space to back it up, because i didn't think about anything like this happening.... i guess i've lost my stuff? :cry:

Well what did you download exactly?

http://www.microsoft.com/download/en/details.aspx?id=24303

There is different downloads for XP or vista, and then again different downloads for x64 or x86

Wish I could help, but I would have to say lesson learned, I would never do on the fly encryption of a file system or other aspects of a file system like moving partitions etc where there is critical files without a backup of the files.

Takes a few minutes to create a backup. If your in a situation where you don't have space, you need to correct that!! You should ALWAYS have a backup of your critical files.

I downloaded KB970401-x86.exe, and the plan was to run it on my home pc (which runs on Win7), so i could use my HDD at my course... but it didn't work so, that's when i removed the pw for Bitlocker and tried to install TrueCrypt.

so.. are my files lost forever...?

    • Windows 11 finally gets redesigned Start menu and more in builds 26200.5641 and 26120.4250

      By George P · Posted

      It's an improvement overall but I'm also of the idea that they should just give users more options and let them have the menu they like instead of just going with one outline and some minor options (though finally getting rid of recommended is great). I know people who don't want pins and would rather it all be just the list/grid of apps. Others just want pins, others want them side by side and not up on top of each other. Have more layout options and let people mix and match, problem solved.
    • Audio setup question - onboard realtek + pioneer receiver (analog)

      By Izlude · Posted

      Hi all, I've got a Pioneer VSX 815-k receiver. Love this thing, however, my cat did his business on top of it and kinda recked it... Only analog works (5.1 surround RCA inputs). Normally I'd use toslink from mobo to digital in on the receiver, but the result is a ton of loud white noise over the music. Analog works just fine, so I'm forced to use the 3.5mm jacks on the rear of the mobo to the RCA inputs on the receiver. The issue I face is that there is no DTS or anything fun.. Originally, I could play all my MP3s or watch YouTube etc, and the subwoofer would be booming as I like because of the mixing from the DAC. Now with the analog, none of that is happening  I'm wondering if there's some kind of software solution for Windows to get the subwoofer to play as it did when I had it hooked up through toslink, but for analog out instead. As of now, only audio files that were encoded specifically to produce sound to the sub, will work, but nothing else. As to which onboard sound solution my mobo has, this from the website's description: 121dB SNR AMP-UP Audio with ALC1220 & High-End ESS SABRE 9018 DAC with WIMA audio capacitors Sound BlasterX 720°, the top-of-the-line audio engine solution for 4K gaming and entertainment  yea it uses that wonky SBx 720 app to change the audio effects n stuff.. but doesn't help with my issue Eventually yea, I wanna buy a new one. They're about $80 on ebay after shipping, but that will have to wait.

      Serious question here. Why is the start menu such a heated topic? I can't remember the last time that I used the start menu for anything at all other than it pops up when I hit the WIN key on my keyboard before I type for the program I want to run and then hit Enter or to restart my machine. I honestly wish it would just go away, and it just be replaced with the PowerToys Run menu. Am I missing something with the Start menu? I see people always talking about installing third party replacements and such, but I just wonder what some are actually using the Start menu for that I might be missing out on. Genuine question. Hopefully not offending anyone as I know everyone has their own way to work and access things in the OS.

    • These are the Apple Watch models that support watchOS 26

      By Aditya Tiwari · Posted

      These are the Apple Watch models that support watchOS 26 by Aditya Tiwari Apple has announced the latest operating system upgrade for its smartwatch lineup, called watchOS 26, not watchOS 12, as many expected a while ago. The Cupertino giant has unified the software experience across its platforms by introducing the "Liquid Glass" software design and renaming all the operating systems to version 26. That said, the next question is which Apple Watch models will support watchOS 26. Apple has shared the official list of devices: Apple Watch Ultra 2 Apple Watch Ultra Apple Watch Series 10 Apple Watch Series 9 Apple Watch Series 8 Apple Watch Series 7 Apple Watch Series 6 Apple Watch SE (2nd Generation) The upcoming Apple Watch update brings several new features to your wrist. Liquid Glass design gives a fresh look to the UI with updated Control Center and translucent buttons within apps. It's new Workout Buddy feature can use an Apple Intelligence-enabled iPhone nearby to provide personalized, spoken motivation during workouts. Building on the Double Tap feature, you can now flick your wrist to perform actions like muting incoming calls, silencing timers, and dismissing notifications when your hands are full. It is available on Apple Watch Ultra 2 and Apple Watch Series 9 (or later). watchOS 26 is currently available for testing through the Apple Developer Program. It will roll out to general users during the fall season, when Apple is expected to refresh the Ultra and SE models. Note that your Apple Watch must be paired with an iPhone 11 (or later) or iPhone SE (2nd generation or later) running iOS 26. While the list of Apple Watch models that support watchOS 26 remains the same, it won't work with iPhone Xs/Xs Max and iPhone Xr, which were previously supported on watchOS 11. You can check out the respective lists of supported devices for iOS 26, iPadOS 26, and macOS 26 Tahoe.
