Aero harddisk upgrade list Ver. 2.7: (April 23, 2002)

All email addresses have been obfuscated by changing the "@" to "-at-".

This list is intended as an aid for Compaq Aero users who want to upgrade 
their harddisks in choosing the right one (of course, without any 
guarantees). Note that only 2.5 '' IDE or EIDE harddisks with heights of
less than 12.7 mm fit into the Aero. Read also

http://www.zenspider.com/~pwilk/aero/aero-faq.txt

on the Aero page of Philip Wilk
 
http://www.zenspider.com/~pwilk/aero_stuff.html

before upgrading your Aero. It helped me a lot.
Please send any comments on (hopefully) successful (or unsuccessful)
harddisk upgrades to Christian Rausch (Christian.Rausch-at-epost.de).
I will add them to this list as soon as possible.
If you have time, then please check the performance of your harddisk 
with cthdben.exe from the German c't magazine. It can be obtained via ftp

ftp://ftp.ix.de/pub/ct/pci/cthdben.zip

and reports the weighted average and the minimum/maximum  transfer rate
of your harddisk. Note that you should use plain MSDOS (no emm386 loaded,
no smartdrv or other caches loaded) and your disk should be as 
unfragmented as possible to get meaningful results.
It would be best to run this program right after installation of your new
disk. Please tell me the min/max and avg transfer rates of your disk then.
I will add them to this list also.

NEW: The cthdben harddisk benchmark program is now also available from

http://www.uni-passau.de/~gebhard/aero/ftp/cthdben.zip

together with an English translation from Markus Gebhard!


This hint is added by suggestion of
Jean-Luc Chevillard <chevilla-at-linguist.jussieu.fr>:

DO NOT FIDDLE AROUND WITH THE HARDDRIVE PARAMETERS (cylinders, heads, sectors)
THAT ARE REPORTED BY THE SETUP DISK (e.g., v.1.12, Rev.B, generated from 
SP2054.EXE), EVEN IF THEY LOOK STRANGE (e.g., a cylinder count of 1). DO NOT
ENTER THE HARDDRIVE PARAMETERS WRITTEN ON YOUR HARDDISK OR FROM YOUR
HARDDISK MANUAL, IF YOU HAVE ONE. JUST ACCEPT THE REPORTED VALUES!

Best regards,

Christian


Remark from Christian on Ver. 2.5, June 16, 2000:

This list is maintained over a long time now (see "History" below), and most
of the disks in this list are not available any more
(so the prices in this list have become obsolete, too)
I have not removed these entries, not only because of historical reasons, but
because some of you Aero users may still upgrade your Aeros with one of these
disks (e.g., when bought at a flea market for a few dollars).
But beware, it could be that some of the email addresses in the entries below
do not exist any more! So, if you are afraid of running into trouble while
upgrading your Aero with one of the disks below, please check the existence
of the email address of the Aero user in the corresponding entry, so that you
are not alone when you really run into trouble!

Remarks from <manheiw-at-HK.Super.NET>:
(I use the Seagate disk manager ver 7.1 to partition the St92130AG with
 the resulting disk space:
 Partition    Status    Type       Mbytes    System
 C: 1            A       Pri DOS    2047       FAT 16
    2                    Ext DOS    8
 DOS formated c: results in 2,146,631,680 bytes
 d:               8,200,192 bytes
 The cost?
 That's exactly HKD $2000 (which is approximately: USD $256.41) with
 installation cost! (of course not by Compaq..)
)

  weighted average= 1421.9 KB/s

(measured by Steve Houchard, <stevehou-at-mynah.eecs.umich.edu>)
Remarks from Steve Houchard <stevehou-at-mynah.eecs.umich.edu>:
(
Even though this drive has increased the battery life and speed of my
aero, I unfortunately can't recommend it to anyone since the drive's
screw holes don't match up with the aero's caddy holes :(

>From what I've seen, other fujitsu drives have their holes on the bottom
as well so won't work well in an aero.

2.1.4.8 External harddrive solutions

[C] Philip Wilk, 06-Feb-97

There are several companies out there that sell kits to convert 2.5" or
3.5" harddrives into external harddrives. This can be either by PCMCIA or
Parallel. I think the best best company is H45 Techonologies, this is the 
one I use. They can be found at http://www.h45.com/ or 1-800-220-6346. You
can also order from  PC-Connection. Right now the parallel kit is $98 and
the PCMCIA kit is $98, but the the PCMCIA kit requires an additional $100
PCMCIA card from this company. They have drivers for Win 3.1 and Win 95,
and possibly others.
