A further possible reason can be a non standardly connected hard disk This is for example the case if a hard disk is configured as slave and if a CD DVD drive or no drive at all is connected at the same IDE chan nel as master Normally HDShredder can handle that too o Note If an SATA hard disk is not recognized this can also be due to the used SATA controller 3 3 2 SATA SATA II controllers 7 4 2 IDE controller not found There are the following three reasons why HDShredder has not automatically recognized an IDE controller o The IDE controller channel is deactivated e g on an onboard IDE controller Activate the IDE controller channel via the BIOS setup o Standard IDE controllers ISA are not taken into account if PCI IDE controllers are available Connect the respective hard disk to a PCI IDE controller in this case or deactivate the PCI IDE controller or controllers o The used controller does not correspond to the PCI IDE standard Although most controllers support this standardized programming interface there are some controllers which have only a proprietary programming interface More detailed information can be found in 3 3 1 IDE ATA controllers Connect the corresponding drives to another controller PCI IDE controller 7 4 3 Problems with DMA The following principal problems can occur with Ultra DMA o The achieved speed is too slow despite DMA Please consider that the achiev able speed
