高級格式

Advanced Format logo


高級格式 (Advanced Format) 是一項新的標準,增加硬碟資料區的長度,超過 512 位元組的傳統大小,藉此提高格式化效率。「先進格式」標準是由 Toshiba 和其他硬碟製造商起草,並與國際磁碟機設備與材料協會 (IDEMA) 合作制定。
IDEMA 希望透過先進格式標準,確保各家公司所提供的儲存裝置,都能夠相容於未來的檔案系統及作業系統 (OS)。

高級格式可減少不必要的標頭,進而透過強大的錯誤偵測與修正演算法,提高記錄資料的可靠性,最終改善格式化效率。
第一代高級格式 (Generation One Advanced Format) 標準規範 4,096 位元組 (4KB) 的磁區大小,這表示單一磁區內包含傳統 512 位元組的八個磁區。
高級格式標準能夠模擬 512 位元組,以相容於傳統 512 位元組磁區配置的應用程式或硬體。在模擬功能下,資料先以 512 位元組的增額單位傳送至磁碟等待寫入,並於寫入前轉換為 4KB 的單位。

Toshiba Alignment Tool for Advanced Format Hard Disk Drives (HDD) no longer be available for download

TOSHIBA CORPORATION and its affiliated companies (“Toshiba”) made available a Partition Alignment Tool for customers that use Toshiba 4K Advanced Format (AF) hard disk drives (HDD) in Microsoft® Windows® XP operating system (OS) environments. With Microsoft® ending complete support for its Windows® XP OS on April 8 2014, Toshiba will no longer offer the Partition Alignment Tool.

Customers planning to continue use of Windows® XP along with Toshiba AF HDDs should consider the use of a third party alignment tool as it may help improve overall system performance.

An unaffiliated, 3rd party vendor that provides an alignment tool for use with 4K AF HDDs is, for example, Paragon Software http://www.paragon-software.com/home/partition-alignment/. It is important to note that Toshiba does not recommend or endorse Paragon Software or any other 3rd party vendor or 4K alignment utility. The use of such software is entirely at the user’s own discretion and risk, and Toshiba is in no way responsible for such use.
