Q:Use ioctl_disk_get_drive_geometryioctl_storage_get_media_types_ex to obtain only a few disk parameters.I want to obtain more detailed information, including the hard disk serial number. How can this problem be solved?
A:
Indeed, with the I/O control code you mentioned, you can only get the most basic disk parameters. Obtain the I/O control code for the disk factory information. Microsoft is not open in the VC/mfc environment, and someClues. Previously, Lynn McGuire wrote a well-known program n

[Hard Disk fault] mainly refers to the aging of the hard disk or bad sectors caused by improper use. In this way, the machine will easily crash during running. You can use special tools and software for troubleshooting. If the damage is serious, you can only replace the hard disk. In addition, for boards that do not support udma 66/100, you should pay attention to the setting of the hard disk running mode in CMOS.

In addition, for motherboards that do not support UDMA 66/100, you should pay attention to the setting of the operating mode of the CMOS hard disk. "CPU overclocking" overclocking increases the CPU's operating frequency, and may also make its performance more volatile.
theoretically supports only 66MHz bus frequency motherboards, does not support 100MHz bus frequencies, and naturally does not support 100MHz memory. Therefore, the symptom is the same as the memory bar is bad. Motherboards with the Intel 440BX main chipset that support the 100MHZ bus frequency should be used, such as Asus PII B, gigabyte 686BX, Soyo 6BE, or 6BA.
