Manchmal erkennt der Computer die 2. Festplatte nicht!
Was kann ich da machen?

Dann mal den Aufdruck auf der Festplatte lesen. Wenn eine Platte als MasterProgramie hat geschrieben:Hab noch so eine HDD (gleicher Typ) im Schrank rumliegen.
Model: WD2500
Anschluss: S-ATA
Jumper:(Da sind 8 Pins. Auf zwei Pins ist ein Jumper).
Advanced Jumper Settings
Western Digital Serial ATA hard drives ship with a jumper shunt in the Default position
(across pins 1 and 2). It is not necessary to move the jumper shunt on the drive for
workstation/desktop use. For enterprise storage environments, use the following advanced
settings:
SSC_DIS Mode (Default) – Spread spectrum clocking feature enabled or disabled. Default
setting is disabled or jumper shunt is placed on pins 1 and 2. Removing the jumper shunt will
enable spread spectrum clocking feature.
PM2 Mode – To designate the drive as power-up in standby (power management 2 or PM2)
enabled, install the jumper shunt on pins 3 and 4. The mode enables controlled spinup,
mainly used for server/workstation environments operating in multiple drive configurations.
OPT1 - Factory use only.
OPT2 - Factory use only.
Jumper Settings for Western Digital Serial ATA Hard Drives
IMPORTANT: PM2 mode requires a compatible BIOS that supports this feature. If PM2
is enabled and not supported by BIOS, the drive will not spin up and therefore will not be
detected by the system.
