Hard disk Simple English Wikipedia, the free encyclopedia. A hard disk drive HDD, hard disk or hard drive, is a data storage device for computers. The capacity of a hard drive is usually measured in gigabytes GB, however hard disk capacity can also be measured in terabytes when the capacity is over 1. A gigabyte is one thousand megabytes and a megabyte is one million bytes, which means that a gigabyte is one billion bytes. Some hard drives are so large that their capacity is measured in terabytes, TB where one terabyte is a thousand gigabytes 1 TB 1. GB. Serial ATA cables are a common way to connect hard disks. Over the years there have been many disk interface types, though all used the same rotating platter recording technology.

As there are different kinds of hard disks, there are also different kinds of interfaces. In 2. 00. 9, it was common to attach a hard disk using a Serial ATA connection. The connection that came before that was called IDE and is called Parallel ATA today. In large data centers, Fibre Channel is often used. For servers, the SCSI pronounced scuzzy interface is very popular. There are several types and versions of SCSI interface, like parallel and Serial Attached SCSI, each stepping up in terms of speed and price. Within servers, several SCSI drives are often used in conjunction with each other, in order to safeguard against data loss or corruption this is known as RAID and there are many configurations to choose from.

If you are using a serial port and you cant get any communication with the CM1. A, uninstall your serial port. To do this, go into Device Manager, then Ports COM and LPT, then right click Communications Port COM1 and select Uninstall. It should then give you a warning select OK or apply. Then restart your PC. When it restarts, the serial port will reinstall itself. You may see a pop up like found new hardware or something to that effect. Let your PC automatically finish installing it. Now try the CM1. 1A and see if the serial port works. I cant speak to other operating system, but this seems to be the norm for Windows XP. I also had a fellow tell me this fix worked for his Windows 9. Apparently this is a very common problem with a serial port. The only way I discovered this fix is because I have a digital camera that uses a serial port to connect to my old Windows XP machine. The serial port would always seem not to want to work when I wanted to upload photos. Uninstalling and letting the system reinstall the serial port would always get it back to working. The same applies if you are using a serail to USB port adapter. If you cant get it to work, uninstall it from device manager and then restart your PC. Then plug in the adapter and let Windows search for and install the correct driver. Dont bother with using any software that came with the adapter as it may be incorrect or outdated.
