SQL 2008 R2 cluster installation failure - Failed to find shared disks

Question

Hi,
The validation tests in the SQL 2008R2 cluster installation (running Windows 2008 R2) fails with the following error. The cluster has one root mount point with multiple mount points :
"The cluster on this computer does not have a shared disk available. To continue, at least one shared disk must be available'.
The "Detail.txt" log has alot of "access is denied" errors and here is just a sample. Any ideas what might be causing this issue?

Hi,
We were asked by the PSS engineer to give the following privileges the account used to install SQL Server - i am referring to the user domain account as apposed to the SQL service account. These privileges were already applied to the
SQL service account prior to the SQL installation. Assigning these privileges to the user account resolved the issue.
  Act as Part of the Operating Sywstem = SeTcbPrivileg
  Bypass Traverse Checking = SeChangeNotify
  Lock Pages In Memory = SeLockMemory
  Log on as a Batch Job = SeBatchLogonRight
  Log on as a Service = SeServiceLogonRight
  Replace a Process Level Token = SeAssignPrimaryTokenPrivilege
Thanks for everyones assistance.
Cheers,
PK
