| E Block | component that connects the actuator to the head/slider assemblies |
| ECC | Error Correction Code, detects and correct errors in a data field |
| Effective Seek Time | The time it takes to seek data, when all/part of the data needed is already stored in the buffer of the drive (speeds up the process) |
| EIDE (also ATA) | Enhanced Integrated Device Electronics, interface |
| Embedded Servo | Servo data that is embedded on the media. Allows the actuator to fine-tune the position of the head(s). It is a positioning signal that keeps the read/write heads positioned over the data. The advantage of an embedded servo is that the data can flow without interruptions making the drive suitable for multimedia and AV applications |
| ESD | Electro-static discharge |
