Corrupt local cache cannont be fixed

Hey Cannonfodder,

SGNRollback is designed to revert an unsuccessfull installation. It will remove the POA (and revert any bootloader / MBR changes) and uninstall the SafeGuard Client on next boot.

That works fine as long as you do nothing else in between, what I did for several reasons.

So, if the local cache is damaged (and, as it was in my case, the backup folder is empty), you got stuck?!

And can the problem be caused by saying Windows to autologon a special user, so that when SafeGuard tries to "Autologon" after first installation it runs into troubles? Or do you think it was depending on the M2 SSD? (I know, it's a little bit like crystal ball telling, but maybe you already had some experiences on that and can suspect one of the two alternatives more likely ;)

Best regards,

Hans

Hi Hans,

its indeed hard to tell but I would suspect the M.2 Drive to be the problem in this case. Caching SSDs usually do not perform very well with software based encryption (not only talking about the SafeGuard Client).

I'd recommend to take a look at the following Knowledge Base articles:

• SafeGuard Device Encryption and hybrid drives (dual-drive hybrid systems and solid-state hybrid drives)
• SafeGuard Device Encryption: Incompatibilities with SSD cache drives (ExpressCache, Intel Smart Response, Intel Rapid Start,...)

I can only 'crystalball' on the LocalCache corruption but the following might help to uninstall the Client in its current state:

• SafeGuard Enterprise Client upgrade / uninstall: Error 25300 The Sophos SafeGuard Local Cache is corrupt

Thank you for the advices, I will try them out next time I get a machine with such a configuration.

Solution for the corrupted cache was trying to deinstall or repair SafeGuard several times until I first deinstalled the preinstall package before deinstalling the client software. That worked properly, but could have been also a coincidence (or maybe the machine just surrendered to get rid of me).

Thanks again and have a good time!

(You can close this as solved, but "I'll be back!")
