new harddisk parameters in disktab

[stephan berger]

i want to add a new scsi harddisk in my c100 workstation, but it has not been recognized correctly. it is a ST19171W disk with 9,1GB but the new entry in /etc/disktab gives only about 4,5GB... it says also 3600rpm but this disk has 7200rpm. Now i want to manipulate disktab but i don't know the parameters corresponding to my disk.

Hi,

If you realy need an entry in the /etc/disktab for ST19171W, try this:

SEAGATE_ST19171W:
:9.1 GB:ns#94:nt#20:nc#4832:
:s0#9084160:b0#8192:f0#1024:
:se#512:rm#7200:

Bye,
