Replacing a floppy drive


Floppy drives fail because of dirt.

Air is drawn into the system for cooling past the floppy heads.
A dirty head can scratch a floppy that you insert and permanently damage it.
Since drives are very inexpensive, when in doubt, replace it.
It is wise to have a spare or two in stock, since they are crucial for data transfer.


Using the other drive:

Flowcon batchers are usually shipped with two floppies.

From the opening menu, you can select the alternative drive.
All menu options for saving and restoring will use the designated drive.


Testing a drive:

Insert a known good floppy, and from a DOS prompt, type dir a:
The drive should turn, access, and display file information.
Insert a floppy that is erasable.
From a DOS prompt, type format a:/u
When the operation completes (1-2 min) try reading it per above.
The DIR command should show about 1,457,664 bytes free, less if you have bad sectors. If the reported amount is less than about 1,350,000 you have excessive errors.
Reformat the drive.
If the DIR still shows a lesser space free, discard the floppy.


To replace a floppy drive:

Removing the drive:

Turn off the computer and unplug it.
Remove the screws holding the floppy drive in its bay.
Push the drive enough further into the case to make it easier to disconnect the power and data cables.
Remove and tag the old drive as bad.

Installing the new drive:

Turn off the computer and unplug it.
Insert the drive through the front of the case.
Push it in past the mounting point (further into the case) to make it easier to connect the power and data cables.
Connect the data and power cable to the new drive.
The stripe on the data cable (pin 1) goes toward the power connector.
Be sure the data cable is centered correctly on its mating connector.
This is usually an 'open header' type connector, and it is possible to misalign the cable.
Try to keep the cable unmoved at the motherboard.
Verify that the cable is securely attached at the motherboard.
If the cable has been removed, make sure it is not misaligned.
Sometimes the best way to check is to carefully remove and reinstall the connector.
Reinstall the screws holding the floppy drive in its bay using at least one screw per side.


New system Installation:

If the floppy does not work when putting together a new system

Make sure the CMOS is configured to match the drive.
We supply 1.44 meg capacity drives, and you need to configure this menu for both drives.
A missing configuration, or a wrong one like 1.2meg will not work.
