Thread: Toshiba Satellite Pro 410CDT System Disk

  1. #1

    Default Toshiba Satellite Pro 410CDT System Disk

    Hello good people,

    I have been setting up a vintage laptop. It's come to my attention that it normally has a special system/DOS disk. It has an external floppy drive that doesn't work properly when swapping disks and I wonder if it's because it needs that special disk to make MS-DOS play nice with it.

    Would anyone know where I could find this disk?

    Thanks

    I don't remember there being a special disk for the floppy on the 410cdt but it's been a long time since i had one, The floppy was swappable with the CD IIRC, There were several external cases for floppy only - CD only or cases that could take either floppy or CD for these old toshiba laptops, Toshiba/Dynabook has info / drivers for the 410CDT on the US site. https://support.dynabook.com/support...1&osId=3333614

    I have a 430CDT. The 430CDT will be close in many aspects to your 410CDT.

    There is nothing special that I need to operate the external diskette drive. I do not use Toshiba DOS nor the Toshiba 'flavour' of Windows 95. I possess neither. For example, to create the Windows 95 installation instructions at [here], I used an MS-DOS 6 boot diskette, a CD driver, and a Windows 95 CD that I had laying about.

    ( Had I a DOS-only machine, I may have used Toshiba DOS on it due to [here]. )

    Some 410CDT information is at [here].

    Do you see the same symptom when the diskette drive is operated within the 410CDT itself (i.e. ejected from its external case, then substituted for the CD-ROM drive) ?

    I own a 420CDT, have never experienced that issue.
    May you clarify things a bit, when you insert a different floppy disk and type "dir", I'm assuming it gives you a read error or a similar message?

    No, no read error. It just reports the contents of the previous drive.

    Anyway I found what I was looking for - there's a specific Toshiba DOS essential disk. Pity it doesn't fix the issue.

    I suspect the external floppy drive I have is from a different laptop model, as it doesn't fit in the drive bay when taken out of its external housing. Could that be it?

    It's *weird* that it allows disk changes when installing DOS though...

    The maintenance manual for the 410 series includes a drawing of the 410's 3.5" diskette drive on page 1-9. Does your drive look like that?

    Hard to tell.

    In the connectors, do you see any bent pins, or pins pushed through to their housing ?

    The same is seen in an IBM AT when a 1.2M drive is fitted that does not supply a 'disk changed' signal. For performance reasons, DOS, not believing that the 1.2M floppy was changed, simply uses what it has already read.

    As a workaround, try a CTRL-C key combination after the diskette is changed.

    If you are running MS-DOS, then another possible workaround is at [here], noting that you would change the command to reflect a 1.44M drive.

    If this is 'disk changed' signal related, maybe the installer ignores that and does a diskette read every time.

    No it doesn't. Mine has a more angular rear and the front seems more compact.

    Hard to tell.

    The connectors seem completely fine.

    The DRIVPARM command fixed it! Thankyou!
