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
beginning can be used normally, but after a period of time, the hard disk heating will cause the jumper switch internal reed deformation, resulting in poor contact, resulting in the crash, replacement data cable and jumper switch, troubleshooting.
Hard Drive connection fault handling
"Symptom" a Pentium 4 motherboard can support the ata/100,
series, so it's more complicated to distinguish their numbers.180GXP SeriesThe 180GXP series inherits the IBM hard drive number. It is identified by: "ic+ platter size + HDD height + capacity + Interface type + Series model + RPM + cache capacity"The simple representation is: IC "Xx,x,xxx,xx,xx,xx-x", its hard disk nu
as the main disk. For a simple example, you had a Ⅱ20GB hard drive (7200 RPM) and later acquired a 60GB Seagate U6 hard Drive (5400 rpm), so you should set the cool fish ⅱ20gb as the main dish because it's faster.
Th
under the premise that the so-called "a pie" has not been cut, after the intervention of the partition after the device naming, first understand the hard disk partition and the system boot process of some knowledge.Two. Disk partitioning and System startup briefThe hard disk referred to here refers to the traditional disk composed of platters, mechanical arm, spindle motor, the size of the
1, the fatal weakness--vibration
Hard disk is a mechanical product, vibration can be said to be a hard enemy, hard disk internal structure is quite sophisticated, the head from thousands of rpm per minute of the surface of the disc only a few microns high, once the vibration is stronger then there will be read and wri
several minutes to clean up the dust, I have never stopped it (using golden to 6 generations and 40 GB ). In addition, there are three servers that use SCSI hard disks, which have not been stopped for two consecutive years. The hard disk's calorific value is not comparable to the ordinary IDE Hard Disk (10 thousand RPM
press F1 to continue, this is the S.M.A.R.T technology to test your hard drive may be faulty or unstable, warning you need to back up the data immediately and replace the hard drive. With this hint, there is no workaround other than replacing the new disk.
Four, the sound to determine the
of the Data warehouse, all the user data and software are stored in this , it is clear that security, stability for the server hard disk is how important.
At present, the server hard disk according to the different ports, mainly SCSI, SAS and SATA, and several other, and SATA hard disk is widely used in desktop computer (PC)
for special needs of users.
The speed of the hard drive is also different except for the volume. 1.8 and 2.5 are generally only 5400 rpm, and the majority of 3.5 is 7200. There are also more than 10000, the higher the speed of reading write faster.
V. Caching

, but Lenovo to the solid state drive, whether you can understand this problem.
Although the desktop can use a notebook hard disk, in turn, the notebook is not able to use the 3.5-inch standard desktop hard disk, because the internal space of the notebook is limited, the hard disk size is designed for 2.5-inch small
Article Title: seven practical tips for optimizing the hard drive performance of Linux servers. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
In Windows, disk fragmentation is a common problem. If you do not pay attention to it, the system performance may be eroded. Li
Many installation software will be stored in a USB hard disk. In Windows, this means that the USB hard drive must be in NTFS format, because the maximum file size in FAT32 format is 4 GB. However, there will be new problems here, because in RHEL5, NTFS format is not supported by default. In other words, you cannot mount a USB
mode, in fact, the serial technology is faster than the transmission speed of parallel technology.
Easier cabling-the flat, wide line of SCSI cables will no longer be used.
Wider scalability-compatible with SATA.
Lower costs-with the advantage of simplifying the internal connectivity design, you can reduce design costs by sharing components.
Look at this picture, this is the image of the SAS hard drive. Th

Edit summary:
I hope these software can give you help when your hard drive data is lost. Although these software can reduce our loss to a minimum, but we should also be from a number of details to avoid the perfect hardware data loss, small set also in the hard drive to protect the small common s
1. First put Ubuntu shutdown.2. Click on the menu in VMware vm-->settings3. In hardware, click the Add button below and choose hard disk-->next-->next-->disk size (GB) is the size of the new drive-->next-->finish--> Ok. This will have a hard Disk 2 in VMware's devices.Third, the next step is to go into Ubuntu and mount the new
When the computer suddenly crashes or loses power, is the hard disk data lost? Did the important USB flash drive files be accidentally deleted? Computer poisoning, file loss or unreadable? The system suddenly crashes and important files are lost? The most feared use of computers is the loss of important data due to sudden and catastrophic failures, misoperations, computer virus attacks, hardware faults, and
