How can you identify the IDE cable for hard drive and floppy drive?
The two most common types of IDE ribbon cables are the 34-pin cable used for floppy drives and the 40-pin cable for hard drives and optical drives.
What are the two main differences between a PATA drive cable and a floppy drive cable?
Floppy drive channel cables look similar to PATA cables, but are a different standard. Floppy cables use a similar-looking ribbon to PATA and feature 34 connector pins compared to PATA’s 40. The floppy cables and ports are marginally smaller than PATA cables and ports.
How many hard drives can a PATA cable support?
The answer: A) One PATA is a good example of a drive technology that supports up to two devices per motherboard interface. There’s no common hard drive interface type that has a maximum of four devices per interface, although SCSI can easily support four drives on a single interface.
How many PATA drives can be installed on a system?
Most computers will have two ATA channels (primary and secondary), so we can have up to 4 ATA drives on our system. The thing is, when we connect two drives on one cable we also have to configure the master/slave relationship between those two devices.
How many PATA hard drives can you have on a system with two PATA hard drive controller?

|---|---|
| How many PATA hard drives can you have on a system with two PATA hard drive controllers? | Each controller supports two drives. |
| How do you differentiate two PATA drives on the same cable? | PATA drives use master/slave jumpers to differentiate between the two drives. |
What is the maximum eSATA device cable length?
The eSATA or external cables are designed to bring standard internal SATA drive performance out of the PC. Using a shielded cable with a maximum length of 2m, these high specifcation cables comfortably outperform both the more traditional USB and IEEE 1394 technologies.
Does SATA cable length matter?
SATA spec is the cables should be between 30-100 cm. Shorter than 30 cm (12 inches) and you may have interference problems with internal reflections. Longer 1 meter (40 inches) and you may have problems with signal degradation.
Will there be a SATA 4?
There is no SATA 4 and there probably never will be. Mechanical drives like hard disks and optical media don’t even come close to saturating the 6 gigabit link SATA 3/AHCI provides.
What are the 4 extra pins on a SATA drive?
A jumper pin is a rectangular connector that creates a circuit between two pins. Seagate SATA drives have four pins, while Western Digital SATA drives have eight pins, with the additional pins to be used by technicians or your network administrator for powering up the drive while in standby mode.
Are all SATA connectors the same?
All the SATA ports on a motherboard are the same speed, but all motherboards do not support the same SATA speeds.
What is the 8 pin on my hard drive for?
Pins 1 and 2: Enables spread-spectrum clocking (SSC), which helps deal with excessive electromagnetic interference. Pins 5 and 6: Limits transfer speed to 3.0 or 1.5 Gbps, depending on the model. Pins 7 and 8: Enables support for the Advanced Format disk option in some older versions of Windows.
What are the pins for on a hard drive?
You may have pins on the back of your hard drive that nothing is connected to. These pins are called jumpers, and are used to enable specific types of settings. They’re not used so much with modern hard drives, except in some special circumstances.
Why is Molex bad?
Why is molex good for bad. One of the big reasons against molex is that, even though there is the notch that’s supposed to prevent you from plugging the connector the wrong way around, it’s still possible to plug it far enough in for the pins to make contact, sending 12V on the 5V rail and vice versa.
Does Molex plug into SATA?
Another option is to use a molex to SATA adapter cable. By going this route, you won’t need to worry about swapping out your power supply. Instead, all you need to do is plug the adapter into your PSU. Then plug your hard drive into the other end, and you’re good to go.
Do SSD need 3.3 V?
One problem we have with testing mSATA SSDs is the fact that they require an mSATA to 2.5″ adapter with a voltage regulator since 2.5″ SATA is 5V whereas mSATA spec is rated at 3.3V.
Do SATA SSDs need 12V?
Most ssds are 5v only, most 3.5in hdds need 12v and 5v to turn on.
