Encryption software compatibility

I intend to test various encryption software on my PC. I would like to know if there are any known incompatibilities between, let's say TrueCrypt and FreeOTFE or PGP and DiskCryptor.

PGP documentation says PGP is incompatible with encryption products from GuardianEdge Technologies: Encryption Anywhere Hard Disk and Encryption Plus Hard Disk products (ex PC Guardian products). It also says that Safeboot Solo and SecureStar SCPP can coexist with PGP Desktop on the same system but will block PGP WDE feature. Obviously they comment on commercial software but omit, perhaps deliberately, freeware products like TC, DiskCryptor and FreeOTFE.

Is anyone aware of any incompatibilities? Driver conflicts?

I would like to make an experiment: encrypt a whole drive with PGP WDE, then encrypt a particular partition on that drive with DiskCryptor, make a TC volume on that partition and inside the TC file volume nest several FreeOTFE volumes. I know that's unnecessary, but I would like to test if it can work. What I don't want is to lock myself to a point where there's no way out or to crash the system.

Any warnings?

 

One thing to note: I had constant BSOD's when TC and DC were installed at the same time. not sure if it was my system or a conflict between them but it got annoying fast.

Now I have done something similar: I encrypted my HDD with TC and then bitlocker. I am sure it would work with PGP as well.
