So kommen Sie an die Festplatten-Parameter

Hallo,

mal eine ganz banale Frage:

Wenn ich eine Platte habe, die das erweiterte LBA-Protokoll erfordert (über128GB, wenn ich mich nicht irre) das BIOS es aber nicht unterstützt;
werden dann die Palttenparameter oder ID, oder was auch immer angezeigt?

Gruß deoroller

 

Ich hab hier ein Prg IDEINFO. Das ist aus 1991 und gibt mir die folgenden Daten wieder:


IDE/AT Drive Identify Program 1.0
(c) Copyright 1991 by Thomas J. Newman
All Rights Reserved.

The System BIOS reported 2 hard drive(s).
A scan of the hardware found 2 IDE/AT hard drive(s).

Drive 0 Information

Cylinders........... 16383
Heads............... 16
Sectors per track... 63
Bytes per track..... 0
Bytes per sector.... 0
Buffer Size......... 1821 Kb
ECC bytes........... 52

Model Number........ ExcelStor Technology J360
Firmware Revision... V22OA63A
Serial Number....... VNVB01E20ENTQA

Drive capacity...... 2015 Mb

Das Programm ist Freeware und hat gerade mal 4,84KB. Natürlich stimmt die Größe nicht, das es nur 2GB anzeigt. Aber die Info ist prima.

 

erkannt werden solche platten schon nur das sie immer als 120 GB Platten angeben werden da hilt nen passenden controller oder ein dementsprechendes BIOS Update

 

Hallo,
wenn Du Dich in Pascal auskennst, oder jemanden kennst, der sich auskennt,
hier ist die 1997er Quelle von IDE-Info. Vielleicht willst Du ja das
Prog. anpassen?



program IDE_Info;

{
IDEINFO.PAS -- v0.1

Reports IDE information from installed IDE hard drives.

TP source code written by Scott Earnest (setech@ix.netcom.com), 1997.

Based closely on C code written by Doug Merrett (dcm@mincom.oz.au),
available on sites as DUG_IDE.C in DUGIDE10.ZIP.

Disclaimer: Standard. It works on my system, I can't guarantee it will
work on yours.

Known problems: WILL NOT WORK IN A WIN95 DOS SESSION. This may have
something to do with the way Win 95 intercepts low-level I/O in its DOS
sessions. It will, however, work under DOS 7.0 if you boot directly to
DOS without starting Win 95.

Note: This code is rather sloppy and IMHO not well organized. There are
very few comments, so modify at your own risk. Also intended to work with
the first IDE channel only.
