The floppy cable has a twist in the cable.
All "modern" floppy cables have at least one special "twist" in them. IDE cables are flat.
used on a floppy
A 34-pin ribbon cable.
The floppy drive cable would be about half the width than the other.
Floppy Ribbon : The floppy cable has 34 wires. There are normally five connectors on the floppy interface cable, although sometimes there are only three. These are grouped into three "sets"; a single connector plus two pairs of two each (for a standard, five-connector cable) or three single connectors. IDE Ribbon : IDE cables consist of either 40 individual wires or 80 individual wires. Ultra ATA/66 or later devices need the 80 wire cables to operate efficiently. Most of these wires are used to transfer data between the motherboard and the drives.
the technical name is frc i.e flat ribbon cable
The ribbon cable is either plugged in upside-down or is damaged.
Many newer systems don't have any ribbon cables at all. Ribbon cables were used for IDE drives, SCSI drives, and floppy drives. The number of cables will depend on the number of drives in the system (16 drives per SCSI cable, 2 per IDE cable, and 2 per floppy cable).
By the colored stripe on the cable it refers to the first pin.
A 34-pin ribbon cable will connect a floppy drive.A 40 (or 80) conductor ribbon cable is for (E)IDE devices.Other ribbon cables may be used (80 conductor for SCSI, and in older systems, MFM and RLL Hard drives).A smaller ribbon cable (10 conductors) may be used for USB Headers.I think that covers most of them.
Failed FDC means that the Floppy Disk Controller is no longer responding. Possible solutions to this issue are to replace the FDC (not so easy on integrated MBs) or possibly replace the floppy drive. This can also occur when the ribbon cable connecting the floppy drive is not inserted correctly.
If there is a backup done select the date on the backup to when the ribbon was there. Any computer technician can do this and it shouldn't take more than ten minutes.
your power supply has a small plug attach to it with several larger ones that go to your cdrom and hard drive it will fit in to the back of your floppy
