SYMPTOMS
On a Microsoft Windows Server 2003-based computer, an NTFS file system partition was formatted by using an allocation unit size (cluster size) that is smaller than 4,096 bytes. When you create many files on this partition, event ID 55 may be logged in the System log:

Event Type: Error

Event Source: NTFS

Event ID: 55

Description:

The file system structure on disk is corrupt and unusable. Please run the chkdsk utility on the volume &quot;Drive_letter:&quot;

Note To determine the allocation unit size, type chkdsk.exe : at a command prompt, where   is the drive letter of the volume. The allocation unit size appears to the left of bytes in each allocation unit.

For example, when you run Chkdsk.exe in read-only mode on a system drive, you receive results that resemble the following:

173550163 KB total disk space.

113608092 KB in 151865 files.

67348 KB in 10314 indexes.

0 KB in bad sectors.

296991 KB in use by the system.

65536 KB occupied by the log file.

59577732 KB available on disk.

4096 bytes in each allocation unit.

43387540 total allocation units on disk.

14894433 allocation units available on disk.

Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
