Hi all, i have this oddball issue with an FDD for my Toshiba CDT480. The thing is, the FDD did not work originally (when i bought the computer + internal CD + external FDD) and i noticed a broken belt and replaced it. No issues.
But then when i tried to use the drive, it would not read (known good) floppies whatever i tried. So i tried to adjust the stepper-motor alignment in very small steps (spending a lot of time doing this) and eventually it 'sometimes' can read the directory, but most often gets the read error.

After some investigation (and asking one acquaintance of mine who has the exact same computer) i learned that an external FDD from the Toshiba Tecra 8000-8200 line actually fitted his external enclosure and so i went on Ebay and bought this exact drive.

I compared the original drive unit itself against a bunch of other slim-floppy drives that i have around and it differs from the rest of them as the connector against the drive itself is wider than a "standard" slim-floppy.
When i got the Tecra drive home today, i noticed that this unit also was of the "narrower" (i.e "standard") kind.

Fortunately, in the end i was able to extract the internal CD from its housing and managed to slide this Tecra drive inside it instead (Tecra drive and CD uses the same "narrower" connector fortunately) and so now i have an internal FDD instead (but no CD any more, but thats ok).

My actual question: Was the 480CDT released in different specifications (with wider/narrower connectors on external FDD and/or internal CD/FDD)?

Adding some images for clarification. Wider connector is the original FDD and narrower is the (new) Tecra unit
