As we all know, computer misoperation is a frequent problem of data security risks, especially in the hot summer, people will be easily tired, a little careless, it may delete data or partition misuse, once the important data is lost, it may be given to the user Bring huge losses. After the data is lost, if an incorrect method is used for data recovery, it is likely to face even greater losses and even complete data recovery. The following Darth Hard Drive Data Recovery experts introduce some common data loss cases and recommend the correct data recovery method.
Hard disk data recovery method after deleting partition
Figure 1 disk 1 divided four partitions in good condition
Looking at Figure 1, Disk 1 is a 250GB hard drive with a total of 4 partitions. Each partition is in good condition. Next we delete the partition and see what effect it is, as shown in Figure 2. When deleting a partition, the system will prompt: "All data on this volume will be lost, do you want to continue?" After the partition is deleted, it looks "unassigned" on the resource manager. When we delete all four partitions, the entire hard disk becomes unassigned, just like the new hard disk is initialized.
Figure 2 four partitions are all deleted
If you use your computer with carelessness, you may encounter accidental deletion of the partition. Here we introduce how to perform a complete data recovery operation. For the average user, we recommend D-Recovery Standard Data Recovery Software Standard Edition, which makes it easy to recover data completely, and all partitions and file directory structures are very good. Recovering the problem of partition deletion, D-Recovery Standard works best in the currently known data recovery software.
Below we detail the entire process of D-Recovery Standard Dash Data Recovery Software Standard Edition recovery partition error deletion. As shown in Figure 3, we open the standard version of D-Recovery Standard, the interface is clean and very friendly.
Figure 3 D-Recovery Standard Dash Data Recovery Software Standard Edition interface
Figure 4 uses the Darth Data Recovery Software Standard Edition to search for partitions.
Select the second disk, click the right mouse button and select the search partition, as shown in Figure 4.
Figure 5 sets the number of heads, cylinders, sectors
D-Recovery Standard can automatically identify the number of heads of the hard disk, of course, can also be manually modified, the number of heads is critical for hard disk partition data recovery, this feature is also a major feature of Darth data recovery software.
(Note: Windows is based on cylinder, head, and sector. The number of heads, cylinders, and sectors in each partition is regular. We can scan according to this rule. Quickly find out. The number of heads is the number of logical heads that are mapped out after the hard disk is attached to the computer. It is different from the actual number of heads. The number of logical heads that can be realized on the same hard disk on different computers may be different.)
Then click OK, Das data recovery software starts to scan the partition table, as shown in Figure 6. The Dass data recovery software scans quickly, with a 250GB hard drive and a scan time of about 5 minutes.
Figure 6 Darth data recovery software standard version began to search hard disk partition
Figure 7 Das data recovery software searched for four partitions
After the Darth data recovery software search partition is completed, four partitions have been searched, and the number of partitions is the same as before we deleted the partition. Let's see if the data is intact.
Figure eight double-click the third partition part2 to expand
Figure 9. The third partition can be expanded normally.
After the third partition is expanded, the directory structure is very complete. We examined the other three partitions separately, and the same directory structure is intact. In order to restore the hard disk to a normal state, we need to rebuild the partition table.
Figure 10 Right click on the disk one, select the partition table operation
Figure 11 Select partition table reconstruction
Then select the partition table to rebuild and click OK.
Figure 12 It is recommended to back up the current partition table before rebuilding the partition table.
At this time, the Darth data recovery software will prompt a warning: the partition table needs to be backed up before reconstruction. Backing up the current partition table can achieve the function of “repentanceâ€. That is to say, after rebuilding the partition table, if it is not satisfied, it can be restored to the reconstruction partition. The state before the table, this function is very practical, and I hope that readers will get into the habit. After backing up the partition table, click Save. At this time, the data recovery work is basically completed. Next, let's verify.
Figure 13. We select disk 1 in the device manager and uninstall it.
After unmounting the disk, we can rescan the new hardware or reboot the system. As shown in Figure 14.
Figure 14 Scanning and detecting hardware changes after uninstallation
The system will soon be able to detect new hardware, as shown in Figure 15.
Figure 15 detects hardware changes after uninstallation and quickly detects new hardware.
Figure 16 We look at disk management again, all four partitions are restored successfully.
Summary: Hard disk partition accidental deletion, partition loss, hard disk prompt formatting, unassigned, etc. are all areas of partition data recovery. The standard version of the Darth data recovery software we tested does have obvious advantages in this function.

Height Adjustable Study Desk And Chair
There are many styles of study desks on the market now: foldable, inclined, horizontal, adjustable height, extended desktop... All designs are convenient for children to use, but the premise is that its design must be It is safe. Make sure that the folded one will not catch the child's hand, and there will be no safety hazard in the front and rear corners of the folding table (the child accidentally knocks it), and choose a table with a rounded corner design.
