The limitations youve put on the solution to this question make this
an interesting challenge. After researching your question and
examining the Toshiba 7020ct manual, I believe I have a solution for
you that meets your requirements.
First of all, your last question clarification mentions IDE and SCSI.
Please note that these drive connection technologies are fundamentally
different and neither the drives nor the cables can be mixed. (SCSI,
which comes in many varieties, may have a dozen or more drives chained
together; IDE has a maximum of 2 drives per cable.)
Second, as you already noted, IDE cables for laptop drives are
different than those for desktop machines. Standard IDE drives use
40-pin connectors, and use a separate molex connector and cable for
power. Laptop IDE devices generally use 44-pin cables that include
the power. The 44-pin interface is smaller than the 40+power cable,
making it an attractive choice for laptops, where space is at a
premium. There are converters/adapters that are sold to go between
the two standards.
Now, as to your question about dual-headed laptop cables; they do
exist. You can purchase one from CablesOnline.com. Specifically, see
this page which has a 12 inch 44-pin cable for 2 drives:
Cost: about $10.
Just because the cables fit, however, does not guarantee that this
method will work. In a desktop computer, there are usually two IDE
controllers (a Primary and a Secondary) and each controller can have
two drives attached (Master, Slave). This allows desktop computer to
have 4 IDE devices (Zip drives, hard disks, DVD, CD, CD-RW, etc.).
Laptops on the other hand, are not generally designed for more than 2
devices a hard drive and a CD-ROM device. (For the purpose of this
discussion, Im ignoring the floppy controller).
Its entirely likely that the laptop only has one IDE controller and
can support only 2 IDE devices. In the case of the Toshiba 7020CT,
the CD-ROM is external, through an optional docking station. This
brings up the possibility that the second drive of the IDE chain is
hard-wired to the docking station connector and thus may not be
possible to disconnect.
So, what are your options?
1) Try the cable, plug both drives in and unplug the CD-ROM, if you
have it. Check the BIOS and see if both drives are recognized. If
so, youre in luck, copy the files, and youre done.
2) Seek an alternative method of hooking up the drives.
Recall that for two IDE drives on the same chain, one needs to be
configured as master, the other as slave. (For details, check the
instructions that came with the new drive, or read the labels printed
on the top of the drives.)
If an alternative is required, I have another suggestion: if you own
the external CD-ROM docking station, you may be able to remove the CD
drive from it and substitute a laptop hard drive. (I note in passing
that Toshiba docking stations appear frequently on ebay, so if you
dont own one, its conceivable that you could pick up one fairly
inexpensively.) Its likely that youll need a 44-pin to 40-pin
converter for this, such as the following at CablesOnline.com:
Cable Cost: about $7.
Barring the above, you may not be able to directly connect both drives
across the IDE interface. So that leaves PCMCIA interfaces, USB, or
additional computers / network copying. None of these fall into the
easy cabling solution you were seeking.
There are a few other things you should be aware of. First, youll
want to make sure you have the most recent flash BIOS version
installed for your Portege. Typically installing larger drives into
older machines is fraught with problems from IDE BIOS limitations.
But from the details that one user wrote about upgrading and
installing FreeBSD on the 7020CT, a 20GB drive should be recognized
properly in your laptop. (See
The article above mentions BIOS version 8.10; I verified that version
is the most recent available for download on Toshibas web pages.
(You can find the downloads by going to Toshiba.com, entering the
support section, selecting computer support, and specifying your
model.) Read the instructions for flashing the BIOS carefully; done
incorrectly you can permanently damage your computer.
Finally, the issue of actually copying the data arises. Most likely,
youre going to want/need software which can do a bit-for-bit copy of
the NTFS partition from drive to drive. This is to preserve the file
permissions and ownership settings. Popular software for this exists,
such as Powerquests Drive Copy ( http://www.powerquest.com/drivecopy/
). Its possible that your new drive came with a floppy disk
containing simple partition copying software as well, such as
Seagates DiscWizard software (see
http://www.seagate.com/support/kb/disc/discwizard.html ). Another
alternative may be Norton/Symantec Ghost (
I hope this fully answers your question. If any of the above is
unclear, please dont hesitate to post a request for clarification.
I initially found references to CablesOnline from Usenet postings in
But a winning google search proved to be 2 44-pin ide laptop, the
first two hits of which were relevant CablesOnline pages.
A search for portege 7020ct 20GB IDE revealed the FreeBSD page
indicating a user had installed a 20GB drive into this model laptop.
