This question may be old but if you still don't know. Slave basically means like a second drive. One that doesn't need an os and is just put in your pc as secondary storage. Your primary or master hdd is the one you boot or post from and has windows installed. This is just the basics there is a little more to it.
I do mean an external hard drive.
Main Hard Drive
Whenever hard dRIVE is used, it blinks. It shows running of hard drive.
Hard Disk Drive
The cache size is refers to the size of buffer on the hard drive. The bigger the the buffer, the less the hard drive has to access the drive. Also it improves the time that the computer needs to access data from the drive.
Of course, copy all your programs and files you need from the old hard drive and put it on your new hard drive BEFORE formatting the old hard drive. Formatting your hard drive will mean losing everything and a slim chance of getting it all back.
Installing the program to your hard drive
it is a Czech word for slave or hard worker. a machine or a piece of machinery
To allow for two drives on the same cable, IDE uses a special configuration called master and slave. This configuration allows one drive's controller to tell the other drive when it can transfer data to or from the computer. What happens is the slave drive makes a request to the master drive, which checks to see if it is currently communicating with the computer. If the master drive is idle, it tells the slave drive to go ahead. If the master drive is communicating with the computer, it tells the slave drive to wait and then informs it when it can go ahead. The computer determines if there is a second (slave) drive attached through the use of Pin 39 on the connector. Pin 39 carries a special signal, called Drive Active/Slave Present (DASP), that checks to see if a slave drive is present. Although it will work in either position, it is recommended that the master drive is attached to the connector at the very end of the IDE ribbon cable. Then, a jumper on the back of the drive next to the IDE connector must be set in the correct position to identify the drive as the master drive. The slave drive must have either the master jumper removed or a special slave jumper set, depending on the drive. Also, the slave drive is attached to the connector near the middle of the IDE ribbon cable. Each drive's controller board looks at the jumper setting to determine whether it is a slave or a master. This tells them how to perform. Every drive is capable of being either slave or master when you receive it from the manufacturer. If only one drive is installed, it should always be the master drive. Many drives feature an option called Cable Select (CS). With the correct type of IDE ribbon cable, these drives can be auto configured as master or slave. CS works like this: A jumper on each drive is set to the CS option. The cable itself is just like a normal IDE cable except for one difference -- Pin 28 only connects to the master drive connector. When your computer is powered up, the IDE interface sends a signal along the wire for Pin 28. Only the drive attached to the master connector receives the signal. That drive then configures itself as the master drive. Since the other drive received no signal, it defaults to slave mode.
I'm not sure what you mean by hard drive history, but if you mean recently used programs, documents etc then you can use a tool called CCleaner (http://www.ccleaner.com/)
work hard but not so hard that you become obsessed. the phrase was written by Benjamin Franklin
it means hard drive port is not working properly.
