Hard Disk

The hard disk used must be a 2.5 inch IDE compatible
type with a capacity of 815 megabytes or more, but some
types may have different mounting requirements or may
not function properly. Yamaha recommends the follow-
ing hard disk units:
Toshiba MK0803MAT
Toshiba MK1003MAV
Fujitsu M2724TAM
The maximum effective use of any hard disk used with the
PSR-8000 will be 780 megabytes, even if the hard disk itself
has higher capacity.
Please note that these recommendations may be changed
at a later date. Ask your nearest Y amaha representativ e or
an authorized distributor listed at the end of this owner’s
manual for information on the latest hard disk recom-
mendations.
Install a hard disk at your own risk. Yamaha will not be
held responsible for any damage or injury resulting from
improper installation or the use of a hard disk other than
one of the types recommended by Yamaha.
