Re: Wdc ssc
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) WDC SSC Jumper settings |
