Storage group not backing up

I have an issue with my Exchange 2007 server not backing up correctly.

We have 5 storages groups.  4 of the storage groups backup no problem, but one of the storage groups fail to back up.

The problem I have is that this storage group wasn't purging the log files, and the drive ran out of space.  So I was advised by Microsoft support to manually remove some of log files.  I did this but now the storage group isn't backing up at all.

I have checked the event viewer and got the following errors:

Event Type:      Error
Event Source: Storage Group Consistency Check
Event Category: Log File Validation
Event ID: 305
Date: 01/07/2010
Time: 20:19:17
User: N/A
Computer: UKVMSX01
Instance 1: One or more errors were detected while validating the transaction log files
in '\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy2\Exchsrvr\StorageGroup01\StorageGroup01_DB01\' with a base name of 'E00'. The operation failed with error code -528 (0xfffffdf0).

The consistency check has terminated with error code of -106 (0xffffff96).

Event Type:      Error

Event Category: Exchange VSS Writer
Event ID: 9782
Date: 01/07/2010

Computer: UKVMSX01
Exchange VSS Writer (instance 9e135b3f-c3f4-482c-968f-700e013eb8dd:1) has unsuccessfully
completed the backup of storage group 'StorageGroup01'. No log files have been truncated
for this storage group.

I have looked through a few forums and articles on the web.  Some are saying that I can dismount the databases and doing an eseutil /cc & others are saying to put the log files back in place and run the backup again, this should purge the logs, but its not worked in the past so I can't see it working again, although we have now upgraded our backup software.

One other thing I was thinking of doing was to compress the drive that the logs files are kept on, put the old files back and run the backup and see if this does the purge, would this be recommended??

Any help/advice is most welcome.
