To diagnose problems when disk errors occur while a Traditional volume is mounting, identify whether the following conditions exist:
The server does not have enough memory to mount the volume.
The operating system is experiencing directory sector mismatching. This mismatching can be caused if the media is defective or if the server is turned off without the Down command.
To resolve disk error problems that occur while a volume is mounting:
Check the status of the available cache buffers. If the available cache buffers are fewer than 20%, add more memory to your server.
Minor errors usually correct themselves through normal network use. For example, if a FAT entry is wrong, the entry is updated and corrected the next time the table is written to. If errors do not correct themselves, repair the volume using the Vrepair utility.
