Q with IOCTL_DISK_GET_DRIVE_GEOMETRYIOCTL_STORAGE_GET_MEDIA_TYPES_EX can only get very little disk parameters, I would like to get the serial number including the hard disk of more detailed information, what method? A Indeed, with what you call the I/O control code, you can only get the most basic disk parameters. Get the disk factory information I/O control code, Microsoft in the VC/MFC environment is not open, in the DDK can find some clues. Earlier, Lynn McGuire wrote a very famous program t

Minion sequencing instrument.I. Brief introduction of Minion sequencing technologyThe core of the Minion Nano-hole sequencing instrument is a flow cell with 2,048 nano-holes, divided into 512 groups, controlled by a dedicated integrated circuit.

Delete disk partitions by mistake in ESXi Because you are not familiar with ESXi commands and are careless, you accidentally delete the partitions of the ESXi operating system. The operation procedure is as follows: Obtain disk device information: [Root @ localhost: ~] Fdisk-l [Root @ localhost: ~] Fdisk-l **** ** The fdisk command is deprecated: fdisk does not handle GPT partitions. Please use partedUtil*** Found valid GPT with protective MBR; using GPT Disk/dev/disks/t10.

The hard drive using the SATA (serial ATA) interface is also called a serial drive. In the 2001, the Serial ATA Commission, made up of Intel, APT, Dell, IBM, Seagate and Serial, officially established the ATA 1.0 specification, and in 2002, although serial ATA related equipment was not officially listed, serial The

The Serial ATA 1.0 specification was formally established in 2001 by the Serial ATA Board of Intel, APT, Dell, IBM, Seagate, and th

hard Disk Interface The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all hard drive integrated controller design belongs

care about where the memory comes from. Instead, it gives Allocator the opportunity to make full use of various operating system mechanisms for optimization. In the upper layer, ease of use is also more important than a little performance loss. In addition, the simpler object management implementation during runtime, the better performance in the long run. Sadly, I mistakenly understood the main problems in the other party's mind. At that time, my main focus was on three issues. First, this ru

characteristics of strong, for its other types of hard disk can not replace the status. Development process Early IDE interfaces have two transport modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although DMA mode system resources are low, they require additional drivers or settings and are therefore less acceptable. Later, in the case of higher speed requirements, the DMA mode is more efficient, the operating system starts to support directly, and the ma

SCSI Small Computer System Interface (Small Computer System Interface), which was first developed at 1979, is an interface technology developed for minicomputers. However, with the development of computer technology, now it is completely transplanted to a normal PC. ATA (at embedded interface) The purpose of this interface is to directly connect the bus in the at computer manufactured in 1984 with the driver and controller that are combined. The "at"

number is the primary flag, representing the number of slices in the normal IDE hard drive. For example, "2" means that there are 2 platters in the drive. In Seagate's SCSI drive, the primary ID is the speed of the hard drive. The second number is the secondary flag, which is the auxiliary flag for the hard drive. The secondary flag is valid only if the primary flag is the same or invalid. It is generally used to represent the algebra of hard disks, the larger the number of tablesThe higher the
