Hard drive not shown in disk management

tokeno · 03-20-2009, 06:23 PM

I added a 20 GHz drive as a slave onto a spare box the op sys is on the master the slave has been formated and the drive is not shown in disk management or in controll pannel but is seen in device manager but as you know I can not reformat from here . I have uninstalled it and reinstalled it with no dirrerance . Any ideas?

What are the drive make and models/ Did you verify the master drive is jumpered to master and the slave is jumpered to slave? Is the drive recognized in BIOS? and in Device manager is it recognized correctly by Model Number?

The drive is a Maxtor 20GHz set as the slave by the jumpers the other drive is a maxtor 40 GHz set as the master by jumpers. The 20 GHz is the drive in question it is seen in the Bios and in the correct possition ,also is seen in device manager as a maxtor with the drive numbers . It worked befor I put it in now there is nothing on it and if I could get into it I can reformat it can I do this in safe mode through the mmc ? if so do you know the command?

Are both drives seen in Device manager? Is it identified correctly by model number. What are the model numbers of the drives, and how are they identified in device manager?
