7.2 Keyboard and mouse

Note: In some of the cases, problems with the PS/2 keyboard and/or mouse occurred with an

activated emulation for PS/2 devices. If you do not use any USB input de-vices, please switch

off the PS/2 emulation in the BIOS setup.

7.3 General problems

7.3.1 Slowed down system

If you think the speed of the total system or the deletion speed – also with IDE and SCSI

devices – is too slow, a USB controller can be the cause, even if it is not used (7.6.4 Speed

loss).

7.3.2 Read, write and verification errors

If HDShredder reports errors, these are usually defective areas on the respective medium.

However, general problems with the hardware can possibly also cause (putative) read and

write errors. This is mostly noticeable by a very high number of displayed errors. First of all, try

to fix the problem via the help instructions for the respective hardware types (IDE, SCSI, USB)

because the causes are usually found there. If the problems cannot be fixed this way either,

deactivate step by step the following options, at best in the indicated order:

• CachedMemory

• Read cache and write cache

• DMA

• SharedMemory

If the problem does not occur any more after having deactivated a certain option, the previ-

ously deactivated options can be reactivated as a test.

7.4 IDE/ATA/SATA

7.4.1 Drive not recognized

If HDShredder does not recognize a certain drive, there can be several reasons. Perhaps the

controller which the disk is connected to has not been found (7.4.2 IDE controller not

found). A further possible reason can be a non-standardly connected drive. This is for example

the case if an IDE drive is configured as slave and if a CD/DVD drive or no drive at all is con -

nected at the same IDE channel as master. Normally, HDShredder can handle that, too.

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:
