Product Limitations
The following limitations still exist in Rollback Rx v9.0:
Hard Disk Support – Rollback Rx can only protect one IDE/SATA/PATA hard drive. If a system has more than one hard disk, Rollback Rx will protect the drive designated as
the “Primary.” Rollback Rx does not support SCSI, RAID or MIRROR hard drive configurations.
Booting From an External Media (OS) – Rollback Rx cannot protect the hard drive when changes are made to the hard drive from an external or foreign (non-Windows)
operating system bypassing Rollback Rx protection drivers. For example, booting from a CD-ROM will start a different OS that may be able to change the hard drive and
produce unpredictable results.
Disk Encryption Programs that Intercept Low-Level Disk I/O – Rollback Rx may conflict with some applications that proxy low-level disk I/O.
Compressed Drives – Rollback Rx cannot be installed on compressed NTFS drives. (The workaround is to uncompress the drive, install Rollback Rx and then re-compress the drive)
Disk Repartitioning – The disk with Rollback Rx installed cannot be re-partitioned without uninstalling Rollback Rx.
Dual Boot of Windows and Linux OS on the Same Hard Drive – Rollback Rx does not support systems that have multiple Windows Operating Systems with non-Windows Operating
System (like Linux) loaded on the same hard drive.
Use of Defragmenter Programs – Once installed, Rollback Rx blocks the use of defragmentation programs. The reason for this is that Rollback Rx tracks sector change activity,
relocates some sectors, and maintains its own map of all sector locations on the hard drive. Defragmentation is the process of locating the noncontiguous sectors of a file
and rearranging the sectors and restoring them into fewer sectors. As a result, once Rollback Rx is installed, the work done by a defragmentation program would not provide
the desired result. Thus, defragmentation programs are blocked. The need for a defragmenter varies according to file system and the amount of file creation and update
activity on a hard drive. Horizon Datasys recommends that defragmentation be done before installing Rollback Rx. In addtion, Rollback Rx has a build-in defragmenter as the alternative.
Operating System Upgrade – Before upgrading the operating system such as from Windows XP to Windows Vista, you must first uninstall Rollback Rx.
