I/O error during disk initialization. PHYSNAME '%.*s' may be incorrect or %ld (VSTART SIZE) may exceed the size of the device or permissions may be wrong for the device.
The DISK INIT statement has failed because of an incorrect physical device name, an incorrect SIZE option, a non-unique virtual device number, or a permission problem (for SQL Server for Windows NT only).
The action depends on the cause of the failure.
If the error was caused by an incorrect physical device name, be sure you have the correct physical device name. For more information, see the description of DISK INIT in the Microsoft SQL Server Transact-SQL Reference.
The SIZE option of the DISK INIT statement must be specified in 2K blocks. For example, to initialize a 10-MB device, specify 5120 for the SIZE (5120 * 2048 = 10 MB).
The VDEVNO option of the DISK INIT statement must be unique. To determine which virtual device numbers have been used, use sp_helpdevice. For information about using sp_helpdevice, see the Microsoft SQL Server Transact-SQL Reference.
Note If a DISK INIT statement fails, SQL Server must be restarted before the same virtual device number can be used for the VDEVNO option.
If SQL Server was started by the Administrator account, the Administrator must have permission to create a file in the directory specified by DISK INIT. Correct the permissions problem and execute the statement again. Also, see the information about virtual device numbers, above. You must restart SQL Server or use a different virtual device number when you reissue the DISK INIT statement.
