Using Rollback Rx for a while now but thinking about maybe tring something else. Sometimes I have the CHKDSK problem but read in this forum that it may have to do with an error on the snapshot and not Rollback directly. Only once did Rollback give me a real problem restoring to a snapshot but was still able to use the baseline to restore. Now a lot of you say how great FD-ISR is and some use more then one of this type of software.why? I mean some use FD-ISR alone but some use FD-ISR + Paragon Drive Backup or FD-ISR + ShadowProtect. Or some other combo. Why Is ther a major benifit to this? And if I uninstall Rollback Rx to try another one is there a chance that somewhere in between uninstalling Rollback and installing FD-ISR something could go horriably wrong and I would be left with an unbootable pc? That would drive me crazy.
