- You probably set up your Maxtor in CMOS incorrectly and/or you entered the
- actual parameters (ie. more than 1024 cylinders) instead of the recommended
- translated parameters.
-
- The maxtor line will generally work with any number of cylinder, heads, and
- sectors per track such that :
- cylinders * heads * sectors <= total available drive sectors
- total drive sectors * 512 bytes/sector = total drive capacity
- total drive capacity <= 220 mb (or whatever the upper limit for the
- drive is).
-
- Note that there are recommended defaults (contact maxtor for this) for
- translation so that if you lose your CMOS configuration (and of course you
- never wrote down what configuration you set it up as [grin]) then you won't
- necessarily lose your data.
-
- I would suggest you leave the number of sectors per track at 34,
- half the number of cylinders until # cyl is smaller than 1024, while
- doubling the number of heads to compensate for that. That is, assuming your
- drive parameters were correct in the first place.
-
- Please note: It seems obvious, but MANY MANY people overlook this critical
- detail and suffer later: WRITE DOWN THE PARAMETERS you used to configure the
- drive, and TAPE THEM INSIDE the machine. I promise you this will save a load
- of heartache when your CMOS eventually loses its configuration due to a
- power-surge-burp or a drained CMOS backup battery. Without the same exact
- parameters (or at least the exact number of heads and the exact number of
- sectors per track), you would not be able to recover your data reliably in the
- future.
-
- Hope the info was useful.
