then we connect it with external usb device
the maximum number of drives that can be installed depends upon how many drive bay slots your case has and how many SATA connections your motherboard has.
A hard drive or solid-state drive (SSD) is typically housed in a bay within a metal frame in a computer chassis. This bay provides physical support and protection for the storage device, ensuring it stays securely in place within the system.
There are not 4 steps to installing a CD-ROM drive, there are 9-10 steps. # Open the computer case and decide which drive bay you wish to use. (Suggest using the top bay). # Most older cases use screws to secure the drive to the bay, and some use a clipping mechanism. (step is optional if this is first time CD drive has been installed). Remove face plate from front of bay. # Slide the drive into the bay. Leave enough of the drive protruding to be flush with the front cover of the computer case. # Push the clipping mechanisms back into place, or put 2 screws into each side of the drive (this is for bays that use screws) to secure the drive (use screws that came with the drive. Long screws can damage the drive. # Connect a power cord to the drive. # For EIDE drives, connect the 40-pin cable to the IDE motherboard connector and the drive. # Attach one end of the audio cord to the drive and the other to the sound card or, for onboard sound, to the motherboard. # Some drives have a ground connection, with one end of the ground cable attaching to the computer case. Follow the directions included with the drive. # Check all connections and turn the power on. Press the eject button on the front of the drive. If it works, power is getting to the drive. Put the computer case cover back on. # Turn on the PC. Follow the steps in the Add New Hardware wizard to add the device driver for the CD drive.
Two possible solution. 1. Some external USB device comes with external power supply. Please use it to increase the power to the USB device. They are normally about 5 volts. 2. Plug into the USB port on the motherboard rather than the front bay or through the USB hub, The reason is because the USB at the motherboard has more power. Re: 1. They are ALWAYS 5 volts Re: 2. The USB at the motherboard does not have any more or less power than a single hub or the front bay connection. Shared ports, like hubs, have the same current available per connection to the CPU. Finally, power is not the cause of this symptom. It is caused by corrupt or missing DLL's. November 14, 2010 I had the same problem with an Acer Aspire 5515. I plugged in an external hard drive to the front USB port and got the same error message. I then plugged in an 8GB flash drive but to no avail......same message. Finally, I tried devices in the rear USB that's on the motherboard and Eureka!!!! they both worked like they're supposed to. With that said, both ports having different voltage has merit.
I wouldn't if I were you.i have that combination and it's a nightmsre. Main problem being the drive bay cradles prevent you plugging into SATA ports. So you have to have the drive bays sticking out the front.
You can use the universal kit to sexly fit the hard drive into the drive bay.
Attach a cable for the data (IDE or SATA types) between the drive and a socket n the motherboard. Attach a cable for the power (there are always spare cables for this coming from the PSU (Power Supply Unit). Attach between two and four screws at the sides of the drive to hold it in place in the drive bay.
Universal Bay Kit
When referencing a computer case design, an external drive bay is one that is accessible from outside the computer, such as a drive bay that houses an optical drive (CD or DVD). An internal drive bay is not accessible from outside the computer, such as a bay that houses a hard drive. There is no need to have physical access to the hard drive so it does not need a "door to the outside" like a CD or DVD drive.
You would use one when you are trying to put in a hard drive, or any kind of drive, that is too small to physically fit into the drive bay.
