Hello sir, my name is Ajit Agarkar and I am from Mumbai. Can you provide me information regarding the EDC SSC jumper settings for SATA hard drive?

SATA Hard Drive Jumper Settings WD SATA hard drives are factory set for workstation/desktop use.

For enterprise storage requirements, the jumpers can be set to enable spread spectrum clocking or power-up in standby modes.
WD SATA drives are shipped from the factory either with or without a jumper shunt in the spread spectrum clocking (SSC) enable/disable position (on pins1 and 2).
It is not necessary to add or remove the jumper shunt on the drive for workstation/desktop use. For enterprise storage environments, use the following advanced settings:

SSC Mode (Default 1): spread spectrum clocking feature enabled or disabled. Default 1 setting is disabled or jumper shunt placed on pins 1–2. Removing the jumper enables the spread spectrum clocking feature.
SSC Mode (Default 2): spread spectrum clocking feature enabled or disabled. Default 2 setting is disabled or no jumper shunt placed on pins 1–2. Adding the jumper to pins 1–2 enables the spread spectrum clocking feature.
PM2 Enabled Mode: to enable power-up in standby (power management 2 or PM2) mode, place a jumper on pins 3–4. This mode enables controlled spinup by spinup command in accordance with ATA standard and is mainly for server/workstation environments operating in multiple-drive configurations.

OPT1:
150 MB/s data transfer speed enabled or disabled. Default setting is disabled. To enable 150 MB/s data transfer speed, place a jumper on pins 5–6.

OPT2:
Reserved for factory use (pins 7–8)
