What to do if your CD drive is not recognized?
What to do if your CD drive is not recognized?
Verify the drive is activated in the BIOS. BIOS systems vary by device. If you are not sure how to verify the drive settings in your device’s BIOS, contact the manufacturer of your device.
Is it safe to leave output pins unconnected?
Output pins are generally safe when unconnected, but it’s a good practice to connect them to pull-up instead of pull-down resistors to minimize idle currents. Having external resistors also means that heat dissipation is evenly distributed instead of concentrated on the microcontroller itself. Some pins are best left unconnected.
What to do with unused pins on a microcontroller?
The quick and easy solution is to leave these pins unconnected as this means less routing for the hardware as well as less space occupied on the PCB. However, the consequences of doing so can include the unstable operation of the microcontroller in an actual application or, on a serious note, outright damage to the component itself.
Where are the extra 4 pins on the power supply cable?
The extra 4 pins on the cable just hang over the end of the motherboard connector. The 24 pin cable only fits into a 20 pin socket at one end so you can’t plug it in incorrectly. The extra 4 pins were added to the 24 pin version of the cable to provide one extra wire for ground, 3.3, 5, and 12 volts.
Where can I find the manufacturer of a CD drive?
The manufacturer name may not be enough information, but you can find more information printed on the top of the drive. Many CD drive manufacturers have stickers on the top of the drive that contains complete information about the CD drive.
What should I replace my IDE CD ROM with?
For example, if your computer is using an IDE CD-ROM drive, we recommend it be replaced with another IDE CD-ROM. Additionally, you may want to consider upgrading to a drive that offers additional support. For example, if you are replacing a standard CD-ROM, you may want to replace the drive with a CD-R or CD-RW drive.
Can a PCI Express connector be plugged into a power supply cable?
If you use an adapter then be sure to plug the 4 pin peripheral connectors into separate cables coming from the power supply. If you plug them both into the same power supply cable then you are drawing all the power of the PCI Express connector through a single 18 gauge wire. You can usually get away with that but there’s no reason to do it.
