We use Truecrypt for encryption in my company, however recently an employee has got quite the odd problem.
Every once in a while when he boots his Vista pc, it changes the harddisk numbers.
This is a huge problem, because Truecrypt has encrypted partitions on two harddisks (two physical drives), however when the harddisk numbers change truecrypt can no longer "mount favorite", which remembers the numbers as they once were.
Essentially he has:
harddisk(0)\partition(0) harddisk(0)\partition(1) harddisk(0)\partition(2) encrypted harddisk(1)\partition(0) encrypted
So when it swaps numbers, it suddenly reads
harddisk(0)\partition(0) encrypted harddisk(1)\partition(0) harddisk(1)\partition(1) harddisk(1)\partition(2) encrypted
I've tried looking through the BIOS and disk management to no avail.
Any ideas why Vista does this ?
