WDE can't handle AF Drives



With the recent release of SandyBridge capable Macbook Pro's and Dell Latitudes, a storm which has been quietly brewing is coming to the forefront. Advanced Format (AF) drives (http://en.wikipedia.org/wiki/Advanced_Format), a specification in the works since 1998, finalized in 2010, and implemented in 2011, appears to have completely caught Symantec and others off guard when it comes to their whole-disk encryption software. AF drives store data in 4096-byte sectors instead of 512-byte sectors like previous drives. this is a GOOD THING, allowing much larger drives and more efficient use of the bus.

However, Whole Disk Encryption vendors such as Symantec (PGP) apparently chose to ignore the upcoming standard (and drives/hardware currently hitting the market). The result is corruption of the system upon encryption. No word on when a fix will be out.

Common' guys...we saw this coming for years!
