In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. For most disks, each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs), and 2048 bytes for CD-ROMs, DVD-ROMs and BD-ROMs. [1]

2022年12月21日 · A sector is a division, usually 512, 2048, or 4096 bytes large, of a storage device like a hard drive or flash drive. Here's how disk sectors work.

2013年10月9日 · A bad sector on a hard drive is simply a tiny cluster of storage space -- a sector -- of the hard drive that appears to be defective. The sector won't respond to read or write requests. Bad sectors can occur on both traditional magnetic hard …

2023年11月10日 · Here, I will show you how to use MiniTool Partition Wizard to scan the hard drive for bad sectors for free. This tool can not only find bad sectors, but also partition hard drive , clone hard drive , recover hard drive data , etc.

2024年11月29日 · Generally, traditional hard disk drives (HDDs) store 512 bytes of data per sector, while CD-ROMs and DVD-ROMs store 2048 bytes per sector. Newer HDDs and SSDs commonly store 4096 bytes (4 KiB) per sector.

There can be more than a thousand tracks on a 3.5-inch hard disk. Sections within each track are called sectors. A sector is the smallest physical storage unit on a disk, and is almost always 512 bytes (0.5 kB) in size. The figure below shows a hard disk with two platters.
