How do I gain access to the System Volume Information\Chkdsk folder?

Avoid doing this through Explorer. Technically, you can view anything under that folder while running in the system context. Most use a an elevated command prompt coupled with PSEXEC from the Sysinternals suite. If this is a server, I would understand why if there have been recent issues where reboots were delayed. But remember, if this is becoming a common occurrence, you likely have a more serious or underlying problem. Also ensure you are doing this for the purpose of viewing information like CHKDSK logs as making modifications to this folder could create problems and is not supported. Also remember, just because you can does not mean you always should - and you should do this via a PAW.
