GreaseWeazle Trouble Shooting Update – Amstrad 3″ Disks

This is a follow up article to where I’ll covering off a common issue that can be experience when using an Amstrad FD-1 External 3″ Drive.

Reading Track 0.0...Command Failed: GetFluxStatus: No Index
Image may contain: text that says "jason@Jasons-iMac Greaseweazle-vo.20% Greaseweazle ./gw read Amstrad/disk1.scp Greaseweazle v0.20 [F7], Host Tools v0.20 Reading Track 0.0. .Command Failed: LuxStatus: No Index"

The most common causes for this error are as follows :-

  • Have you disconnected the 5V Power Cable inside the FD-1 External Unit? This must be done to protect the GreaseWeazle (remember to put it back when you’ve finished with it).
  • The 34Pin FDC Cable is upside down.
    • The official cable works correctly as supplied, however you will need to file the Key from the Connector to insert the cable into the Drive upside down.
    • If the cable is upside down you will hear the drive spinning and the front red LED Light will be permanently lit (switch one of the connectors upside down).
    • Do not use the Middle connector on a dual drive cable (The one with the twisted cable for Cable Select, as seen on older PC 3.5″ Disks). The Amstrad FD-1 Drive is permanently jumpered to act as Drive B, they were expected to be connected to an Amstrad CPC664/6128 as a secondary drive (Disc controller wasn’t required).
      • Note: I don’t have a DDI-1 and Drive to test the combination for 464 users.
  • Check the command syntax
./gw read --revs=5 --drive B --ecyl=39 --single-sided diskfilename.scp
  • If you believe the drive is configured as A
./gw read --revs=5 --drive A --ecyl=39 --single-sided diskfilename.scp
  • If that doesn’t work, there may be a more fundamental issue with the Drive. Remove the top half of the case (with the drive powered off and unplugged). Reconnect the hardware and check that BOTH the disk and the drive motor spin
    • I’ll upload a video showing the process of replacing the belt, though be aware there’s two major model designs, one with a mechanical write pin, the other with optical. The mechanical write pin version is a real PIA to deal with, but doable.
Ensure the 5V Connector is disconnected before connecting to the GreaseWeazle.
