> To remember the article on a Seagate hard drive (model number st94011a, sn number 3kw1aa08) for data recovery, for example, the first volume shadow disk agile applications (1) first appearance on the hard drive for testing, test results for the hard look intact, no signs of disc opened, pcb circuit board can not see to see obvious signs of waste (2) the hard disk connected to the computer as a slave, in coms below this hard drive can properly identify the relevant parameters, But into the operating system is very slow; first start the operating system, by moving the hard drive cable connected to the computer's usb port on the phenomenon of the mouse away to control all programs out to respond. operating system to show fake crash phenomenon, host system partition can not see, as shown.recovery"> (3) for a more intuitive view of the data area damaged hard drive, this hard drive hanging from the disk, start the computer into dos mode, use mhddsoftware to scan the bad sectors, the results shown from the scan results see this disk bad sectors very tight below to quickly extract with datacompass important data in this drive.recovery"> (4) hard drive will fail and dc, the computer properly connected to the mobile hard disk drive means connected to the figure (5) start the bottom of the control program, open the dc controller power Switching power supply for the failed hard disk, waiting for the hard disk status displays as "ready" that is ready to open on the failed disk read function, as shown.recovery"> (6) Click the" shadow disk "tab, and open the shadow disk initialization, set the figure at the plate corresponding parameters, as shown (7) Click "sector view" tab to view the content of any sector source disk in the "dec" text box, or "hex" text box, enter the address you want to view lba sector , click "view sector" button in the left window shows the corresponding sector data, shown in Figure 5. If the view to the 4040 data is incomplete, that can really read the hard drive data, utilization source data compass explorer (hereinafter referred to as dcexp) to copy the data obtained by clicking "dc explorer" button, the system automatically starts the top of the data recovery process. (8) in the open "dcexp" working interface, click "file recovery" election tab, where you can visually see the partition and file system directories. Click "open disk" button, the program automatically reads the hard disk logical partition information, as shown. ⑼ by reading the partition information in the interface left side of the box shows, by clicking on the "+""-" button to control whether to display partition information, you can see there are three hard disk failures partition, double-click the partition to start under the directory, click the "root" to open the directory Under the document, as shown. (10) to restore the files, and open the file for viewing, the invention in which an image is displayed as shown in (11) to open the picture file with winhex view, you can see in Figure 9 shows the information it is clear that some displayed as "4040," the message that failed to read the contents of the file, which may be due to the location of the part of the data storage caused more bad sectors. ⑿ for such part of the file has been read out, can be agile recovery disk set at the figure. go back to the underlying control softwaredata compass panel, switch to the "shadowdisk control" shadow plate control tab, select the "intensive read" and "ignore shadowdisk" check box, as shown. (13) Click "dc explorer" button to start dcexp procedures, read with the previous method does not completely restore the image file, you can see, the picture has been viewed can be normal, as shown For the other did not read the complete picture, these methods can also be used a second reading. Thus, the data suffer from the hard disk to a full recovery. so we can see, agile figure to use the dial to set the relevant options, you can In the process of data recovery to play an unexpected effect.
