# There is only one file /etc/sysconfig/harddisks for all disks after
# installing the hdparm package.
# If you need different hdparm parameters for each of your disks, copy
# /etc/sysconfig/harddisks to /etc/sysconfig/harddiskhda (hdb, hdc...)
# and modify it.
# Each disk which has no special parameters will use the defaults.
# For each cdrom only the 'EIDE_32BIT' parameter will be used
