IDE Disk (hard drive)

IDE disk (hard drive)

• IBM PC XT develop, use a Seagate 10 MB hard disk for storing programs and data.
• This hard drive has 4 head, 306 cylinders and 17 sectors per track, controlled by Xebec disk checker on a plug-in card.
• Technology is developing rapidly to make the disk checker that previously separated into one integrated package.
• Did the IDE drive technology (Integrated Drive Electronics) in the middle of 1980.
• Technology IDE disk can only handle a maximum capacity of 528 MB of disk and control 2.
• IDE developed into EIDE (Extended Integrated Drive Electronics).
• Capable of handling the hard drive more than 528 MB and supports address LBA (Logical block addressing), the only method that gives the number in sectors ranging from 0 to a maximum of 224-1.
• This method requires checker able to convert addresses into the address LBA head, sector and cylinder.
• Improving the performance of other transfer speed is higher, able to control the 4 disk, able to control the CD-ROM drive.
