As for the driver version, I have not used the latest version, but have used it for more than half a year. It is determined to be the latest version.
In this document, the security mode is available in x61 be8. For other x61 hosts, consider the entire method.

8. IDE interfaces and IDE Devices The ICH4-M provides two independent IDE signal channels, each supporting two IDE devices, with 16 Mb/s pio ide transmission or Ultra ATA 100/66/33 transmission, each IDE device has an independent clock. IDE devices are hard drives and optical drives.Nowadays, an IDE interface technology nam

Linux terminologyMedium, MTDs (memory technology devices) includes from the drive ROM to NOR/NANDFlash card storage, the difference between them is very large, in the linux kernel provides a unified layer for seamless connection to the low MTD chip and into the user Module (user)Module ).
PATA and SATA are both ATA standards, that is, what is often saidIDE. IDE is commonly used in workstations and servers to store OS bootloader and
Sometimes, during maintenance, we always encounter a problem similar to Io, but it cannot be determined whether it is an I/O bottleneck or a hot disk caused by improper configuration of software parameters. at this time, we usually want to know the read/write speed of the disk for further decision-making.
The following are two test methods:
(1) Use the hdparm command
This is a command used to obtain the parameters of the ATA/IDE hard disk. It was writ

Error Analysis: this error is generally caused by a disk error. Sometimes it is recommended to check whether the hard disk connection Red is not in good contact or whether the connection line meets the hard disk transmission specifications, for example, ATA-100 hard drive still use ATA-33 connection line, does not matter to low speed hard drive, but high speed hard drive (Support
I. Use the hdparm commandThis is a command used to obtain the parameters of the ATA/IDE hard disk, hdparm has been written by Mark Lord, the primary developer and maintainer of the (E) IDE driver for Linux, with suggestions from javasnetfolk ). this command should also be used only for Linux systems. For UNIX systems, ATA/IDE Hard Disks may be used less often. Generally, large systems use disk arrays.Easy t

Sometimes, during maintenance, we always encounter a problem similar to IO, but it cannot be determined whether it is an I/O bottleneck or a hot disk caused by improper configuration of software parameters. at this time, we usually want to know the read/write speed of the disk for further decision-making.

At present, all hard disks on the market have S. m.A. r. t.
