The issue is just about TRIM, RX said they support it, while experimented users said no it doesn't.


Level 6
I just asked the following questions to Horizon by email...


Just to be clear, is it only the snapshots that are encrypted ? If I want to transfer my personal files onto a clean installation of Windows, will they be encrypted if I put them on my hard drive first and then install Rollback, OR to encrypt them do I need to install Rollback first and then transfer all my personal files (about 90GB worth of data).

The answer i got from Horizon was this...

No, it's the drive itself. Doesn't matter, either way they're encrypted.

Does anyone know if this is actually correct ?


Is it still a good idea to un-install Rollback every once in a while to keep the SSD fully optimised ? And is there a way of saving snapshots on an external hard drive so i can re-load them later.

The answer i got from Horizon was this...

Doesn't make a difference either way. No, you can't save or move the snapshots to any place aside from the sector level of the primary drive.

Would people also agree with this ?

Thanks for your help and comments.

Avoid to use RX on a SSD drive, RX doesn't allow the TRIM function.
now you have the turn off tray icon option, so you can TRIM your SSD (reboot first) but it will merge all your snapshots.

IMPORTANT EDIT for the Anniversary Update:

Disable Secureboot before installing RX, their drivers doesn't fill the requirement imposed by Microsoft
work with securebooot now.

Windows Restore Point is BS, it restore crap. Yes, RX is a galaxy better, it is the Q&A/tester best friend because it uses the actual system ( drivers, installed apps, etc...) but redirect the writes in a hidden partition.
Oh, I see. I might add Rollback RX into my backup tools because Windows Restore Point doesn't work all the time. What do you mean redirect the writes in a hidden partition?

To explain grossly, the baseline is your real system, then all writes are redirected to a hidden "copy" of the system (snapshot), it is why it is faster than any imaging software but less stable.

Some general questions re Rollback....

Proposed System:
C (250GB):
1. System partition containing Windows , Programs and NOMINAL Docs and Settings:
Win Xp 64 bit
(Yes, I know! I'm willing to take the risk because I've tried 7 and 10 and didn't like them.)
2. DATA partition containing ACTUAL Docs-n-Settings folder, including DESKTOP and other user data
Windows 7 and Data folder
, sharing the same DESKTOP folder as C


1. How much space should I reserve for the C SYSTEM partition (as a guestimate?)

In the past the size of my Windows, Programs and my nominal Docs and Settings folder has grown to 50 GB over about 5 years.

I thought perhaps I should make the System partition 100 GB, but from what I've read, it's not necessarily so that Rollback will need the same amount of space as the System.

In that case, based on people's experience, what is a guestimate of how big I should make the system partition (given the above size of 50 GB after five years).

2. Interaction with Windows 7:
I already know Windows 7 won't be able to see my XP system files properly.
But I assume it WILL be able to see my XP DATA FILES on that second DATA partition. Correct?

2. Is there any danger from Rollback's behaviours to my DATA PARTITION on C?

3. Will Testdisk (say on BootMed) be able to see:

a) My DATA partition on C
b) Perhaps even my protected System partition??
...in case of lesser problems like MBR or MPT corruption, or larger problems like HD failure?

4. Will an app like FILE SCAVENGER (from Quetek, NOT SYSTEM SCAVENGER from Horizon)
be able to see my DATA PARTITON on C, in case of problems?

5. In trying the app, i already saw a concerning error. When I opened one of the virtual drives, my PC kept giving a write error on various files (see below). Any thoughts on this?

("Delayed Write Failed} Windows was unable to save all thedata for the file <file>. The data has been lost. This errormay be caused by a failure of your computer hardware or network connection.")

4. I figure that Rollback is pretty good at preventing alot of the problems that might normally require testdisk or using Windows 7 to fix XP. So it's not such a big deal if I can't use Testdisk or Windows 7 to fix the SYSTEM drive...Am I wrong?

I appreciate anyone's experience on this.
All responsibility is of course my own
