Hello to you all.

I've received this drive with the description : No data acces. Its from a DELL latitude laptop(quite old)

After connecting the drive ive notice this in Winhex



As we can see its an encryption case, whit truecrypt. Now the problem is i am not able to mount the drive.

I've cloned the disk and i am working with the image so that i keep safe user data in case off errors. The cloning went well, no errors.

I've tried to mount the drive whit almost any option that truecrypt has.

Waiting for your suggestions or questions.

Thank you all

can you post sector 0 please
Puedes enseñarnos el sector 0 porfavor

I just did one of these a couple weeks ago (If it is TrueCrypt we're talking about, which Sector 0 will reveal). You need to image to a physical drive, install the TrueCrypt software on the computer, and get the password from the customer. Then you can mount the volume on the computer from inside the TrueCrypt software. I think you have to use the "Mount Without Pre-Boot Authentication..." option since it's from a different computer.

Took me a few minutes to figure it out, but it worked like a charm.

Unless your customer doesn't have the password, then you're in trouble.

If customer doesn't remember the password there are still ways to mount TrueCrypt volume to access data.
You can use forensics tools, example "Elcomsoft Forensic Disk Decryptor".

Decrypts information stored in three most popular crypto containers
Mounts encrypted BitLocker, PGP and TrueCrypt volumes
Supports removable media encrypted with BitLocker To Go
Supports both encrypted containers and full disk encryption
Acquires protection keys from RAM dumps, hibernation files
Extracts all the keys from a memory dump at once if there is more than one crypto container in the system
Fast acquisition (limited only by disk read speeds)
Zero-footprint operation leaves no traces and requires no modifications to encrypted volume contents
Recovers and stores original encryption keys
Supports all 32-bit and 64-bit versions of Windows

Hola!

Aqui esta el sector 0.

Gracias por tu interes.

Hello!

I have already imaged the drive and tried to mount the volume(with password supplied by customer) in different ways with no success.

When y try to mount the drive i get the next message: Invalid password or not a truecrypt volume

This is the way ive tried to mount the drive

How do you know that's actually a Truecrypt volume? Also, have you got the right user password? AFAIK, there's no way of knowing if a volume is indeed an encrypted Truecrypt volume or something else (detection of "just" encryption is possible nonetheless), since there are no headers whatsoever. As per the documentation, the Truecrypt program believes it has correcly mounted a volume if using the provided key it finds the decrypted string "TRUE" at some location near the beginning of the volume.

Honestly i know because the customer said it is truecrypt, and ive based my research on that. Regarding the password ive just asked the commercial department to confirm it again.

Hi. I think I would attempt to decrypt the whole drive/partition. First try in Truecrypt but it probably won't work. So then you could mount the clone drive in a pc and boot from a Truecrypt rescue disk. Select decrypt and see if that works. If it starts to decrypt then leave it until it finishes. It could take up to a couple of days to complete! By the way did the customer create the Truecrypt rescue iso? It would be very useful if they did.

The partition table has been overwritten by testdisk (http://www.cgsecurity.org/wiki/Menu_MBRCode) so that why you can't recover, is not truecrypt bootstrap present on sector 0. You may want to get a working drive install truecrypt and then modify sector 0 on your image with the correct bootstrap for tuecrypt.

Thank you very much. Ill do that and get back with the result .

Probably what happened is the system failed to boot so one of the bright techies in the backroom decided to overwrite the mbr with testdisc. I have seen quite a few like this and usually end up decrpting the drive/volume to get the data back.

You should read the Truecrypt manual on how to restore the Truecrypt boot loader from a rescue disk. If you can't get the volume to boot as a Truecrypt volume you should still be able to decrypt it providing you have the correct password. Que tengas suerte!

Thank you for your answer .

Today i will do it and get back to you with results. Gracias.

I agree, as stated by others, that boot sector does not contain TrueCrypt.

Your only hope of recovery will be to use a TrueCrypt rescue disc to restore the bootloader. It forces you to create the rescue disc when originally encrypting the drive.

If the rescue disc has been lost then the data is unrecoverable.

The customer just notified me that he has the rescue disk...... what a relief.

Hopefully i can restore data.

Thank you all
