How does mhdd work?
MhddIt's a professional hard drive from maysoftTool softwareIt has many other powerful features that cannot be matched by hard disk software, divided into free and fee-paying complete versions。
Now, let's look at the use of professional hard drive software。
Port (thermal keys shift+f3):
The hard disks on each ide mouth are shown so that you can select the hard disks of the respective mouths by the corresponding number, which will then be recorded in the mhd. Cfg file under the /cfg directory, 1 for ide1 owner, 2 for ide1 owner, 3 for ide2 owner and 4 for ide2 owner
Scan (thermal f4):
A face-scan can be used to repair the bad sector in a specific mode, where:
Scan in: chs/lba
: scan in chs or lba mode. Chs is valid only for old hard drives up to 500 m。
Starting cyl
: sets the column where the scan starts。
Starting lba
: sets the lba value that starts the scan。
Wait: wait for the hard drive。
Stop (heat key shift+f4): turn off hard drive motors。
In the case of light grey squares (third squares), it would be more time-consuming to read them;
In the case of green and brown squares (third and fourth squares), the anomaly is read here, but no harm has occurred;
In the case of red squares (the sixth, the last, the last), the reading of edifice here will produce a bad path;
If there is a question mark? This means that there is an error in reading and that there are serious physical defects that cannot be repaired。
Note 1: some hard drives that are very slow to read and write can be seen if they are scanned by the mhdd f4 scan and opened by erasewaits, either evenly spread many ws, or are covered in many coloured squares, which means that they are so slow to read and write because of the fact that a large number of disc sections are defective that it takes longer to read and write each sector, which, taken together, leads to a very slow reading and writing of the entire disk。
Note 2: the low performance and slowness of the older hard drive (under 2, 3g) makes it rare for the first square to appear at the f4 scan test, while the second and third squares appear, and even the fourth square (green square), due to the slow reading and writing of the old hard drive, which does not indicate an anomaly in reading and writing in those sectors。
The use of arrow keys during scanning allows for flexible control of the scanning process, very much like the vcd player: ↑ 2% fast; ↓ 2% back; ← 0. 1% back; 快 0. 1% fast. The flexible use of arrow keys allows for the repeated scanning and repair of unstable, persistent areas。
