  • Article

1/6/2010

The following registry settings are specific to a TexFAT file system. You can place these settings at the root level of the registry hierarchy or at a profile-specific level.

Registry value/type Applies to Description

ReservedClusters: REG_DWORD

TexFAT only

Number of clusters to reserve for cloning. Default is 4.

SectorsPerSyncAtInit: REG_DWORD

TexFAT only

Number of sectors to sync at a time during initialization. Default is 32.

Atomic Sector Writes

TexFAT requires that the underlying block structure support atomic sector writes. The flash driver and most compact flash card hardware provide atomic sector write operations. In cases where the block driver is not atomic, TexFAT cannot guarantee transaction safety.

We recommended the following settings for hard drives and other media with non-atomic sector writes:

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\HDProfile\FATFS]
    "TfatMarkAlways"=dword:1
    "NonatomicSector"=dword:1
    "DisableAutoScan"=dword:1

We recommend the following settings for storage media with atomic sector writes:

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\<Profile Name>\FATFS]
    "DisableAutoScan"=dword:1
