Arrived into work this morning to quite a major issue.
My main file server last night logged Event 55 - The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume. It refers to my data partition.
It has crashed twice since 2 AM last night
Its a pretty new machine with one mirrored array for OS and four other disks in a RAID 5.
I have about 80 users on this box but I have logged them all out to take a full backup which is currently running as last nights failed with the crash.
Most recent patches are from last week and about 10 days ago i installed Symantec Endpoint.
What should I do next? I ran chkdsk in read only mode and it didnt report any errors and the allocation unit size is 4096.
I have seen some posts saying the drive needs to be reformatted because it could be a corrupt MFT but surely there are better ways?
Thanks in advance
