I have a Crucial SSD drive, and I installed PGP WDE on the drive. The drive crashed hard after about 2 weeks of running very slow with PGP, and I had to do a chkdsk to be able to read the data on the drive. So, hooked up externally, PGP could unlock it but it came up with I/O errors when I would try to open the drive through My Computer. Running chkdsk /R finally allowed me to get access to my files, and then unencrypt the drive. Now it seems I can boot and the drive seems fine unencrypted.
I called Crucial about this. They said they do not support software-based encryption of SSD drives, and large part due to the garbage collection process. IN fact, they just integrated support for Windows Bitlocker in the firmware of their newer drives, but no other encryption system. They said the chkdsk probably worked because it was finding files in the area marked for garbage collection, which may not have been cleaned up due to WDE processes. Thus, it became corrupted enough to prompt the crash.
How does this sound to the PGP folks out there? Is it true that PGP WDE should not be enabled on SSD drives?
