HI

I got a replacement HD from HP, a Maxtor diamon max plus 8, it states on
label a 40gig, its to replace a 20 gig that failed.

I fdisked and formatted in another computer for ease, trouble is its coming
up as a 20, so when formatted its 18.6

Never come accross this before, is it because my records show what size its
relacing, so some firmware alters the size, or is a label error? i cant see
why they still would ship lower drives due to cost. The PC im using holds a
40 gig so its a not a case of a old pc being restricted, although i think it
maxs out at 127gb, anything bigger wont be seen.

It has something in jumper settings called cap limit, never seen that before
and there are no jumpers as its set to slave.

anyone know?
thanks

It may be a jumper which limits the size to 20GB, though more likely it's
the firmware used. This is common practice in the OEM segment.

Thanks, at present its slave so no jumpers, there is a jumper for cap limit,
buts thats new to me, never heard of it. Orig drive was 10gig at the time,
replaced under warranty for a 20gig now this is the replacemnt for that,
label says 40 but after fdisk and format coming up as 20 gig........could it
be the cap limit?
thanks

Could be....
If the drive is labeled 40GB, chances are it is a 40GB drive. Limiting the
capacity is a function of either firmware or a jumper, which may be on the
PCB, rather than at the end where the IDE ribbon cable is connected.
