In the event you delete the partition of the challenging disk by error and you will find important information in it, are you currently worried about it! Do not be concerned, don't worry! Right now I will introduce two solutions to bring your tough disk back to life! The initial technique will be to use Winhex, as well as the second process will be to use Diskgen. Of course, the second one particular is reasonably basic, and also the speed is comparatively speedy. It's an ideal software for people who've no foundation for information recovery. Okay, let me introduce my experimental environment first. This is a virtual hard disk taken from the teacher. I do not know how lots of partitions? What sort of partitions are there? data recovery usb stick realize that there's information in it. Now the data must be recovered. Let's talk regarding the very first kind of winhex to hang the really hard disk to be restored to a further pc. Disk 1 is the target tough disk. Now that it has turn out to be unassigned, we have to restore its partition. Open the winhex selection tool----disk editor to open the really hard disk 1 and now get started to analyze: because the very first 63 (0-62) sectors of every really hard disk are reserved for the system, we must start out searching from 63, Visit sector 63. Based on common sense, most of the present difficult disk partition types are NTFS partitions, then 1st observe the ch28 place and find that it really is 00000000, indicating that the judgment is wrong, it should really be a FAT partition. Then at CH20, a set of data 00823E00 is located, which tells us that the first partition is usually a FAT partition and the partition size is 3E8200. Note: If it is NTFS, then a couple of bytes after the offset CH28 for the arrangement plus one will be the sector size on the NTFS partition. Now that how to recover lost data from usb flash drive know the size from the initial partition, you can know its end position plus the next The starting position of a partition. recovery data usb -1 could be the end position of the very first partition. Which is, convert 3E8200 to decimal plus 63 minus 1 equals 4096574. Then the very first partition is from 63 to 4096574 sectors. In case you know the end with the first one, then add one particular to the finish (4096574+1=4096475). The starting of a partition. But, is definitely the next partition the key partition or the extended partition? Not sure, if it can be the next extended partition then there really should be a partition table in the first 64 bytes of 55AA. If it can be not a partition table, then it truly is the principal partition. It is best to look at the position of CH28 or CH20 to figure out what variety of partition. According to typical sense, it must be an extended partition. Go to the 4096575 sector initial. See, the initial 64 bytes of 55AA are not partition tables, and frequent sense deceived me once again. The second partition could be the principal partition. Then look in the position of CH28 or CH20 to establish what type of partition. The size with the second partition (3E823E+1) is recorded in the position of CH28, indicating that the NTFS partition adds his size towards the get started minus 1, which can be his The end position (3E823E+1) is converted to decimal 4096575+4096575-1=8193149 The second partition is from 4096575-----8193149 sector, then the starting of the subsequent partition is the finish plus 1, 8193150 Visit sector 8193150 to see. It can be discovered that there is no information in CH28 and CH20, and it's empty before 55AA, then it shows that this can be a deleted partition table, that's to say the third partition can be a logical partition. This place is the starting location in the extended partition. The very first logical partition begins from sector 63, then add 63 to the starting of the extended partition, which is the starting position of your logical partition. That is definitely 8193150+63=8193213. The same goes to the 8193213 sector. The CH28 position with the sector records the size of this partition (5DE27F+1), and additionally, it shows that this partition is NTFS. Start+Size-1=End, 8193213 +6152832-1=14346044 In this way, we also know the finish position of this partition, then the following sector of your end sector of this partition is the start off of your next partition 14346045 partition three from 8193213-----14346044 sector we see The result is a partition table, indicating that the fourth partition is also a logical partition. This position may be the starting position of extended partition 2. The logical partition starts in the beginning position of the extended partition 2 to the sector 63 back, then adding 63 to the start in the extended partition 2 will be the starting position in the logical partition. 14346045+63=14346108 We see that at CH28, the size on the partition (5D64FD+1)=6120702 is recorded, and in addition, it shows that the partition is NTFS. Start+size-1=end 14346108+6120702-1=20466809 partition Fourth, the sector evaluation from 14346108-----20466809 is finished, and now we know that you will discover 4 partitions in total, assuming 4 disks of D, E, F, and G. D: Principal partition, FAT32 form, beginning 63----------------4096574E: Key partition, NTFS sort, beginning 4096575-------8193149 Extended partition 1: starting 8193150 ------20466809F: logical partition, NTFS variety, beginning 4096575-------8193149 extended partition two: starting 14346045-----20466809G: logical partition NTFS kind, starting 14346108--- ----20466809 With these parameters, we create three partition tables within the partition table (sector 0) with the D drive, describing the E partition and the extended partition 1 separately. Only the parameters in the 3 LBA partition tables are considered here: 000000000B0000003F00000000823E00 (the number of sectors before the 3F000000 partition, 00823E00 partition size) 00000000050000003F823E003F823E00 (the amount of sectors just before the partition 3F823E00, the size in the partition 3F823E00) 000000000F0000007E047D00FC47BB00 (the number of sectors before the extended partition 00823E0023E00 Size) Two partition tables are written in the partition table (8193150 sectors) of extended partition 1, describing F disk and extended partition two, respectively. The two partition table parameters are 00000000070000003F00000080E25D000000000005000000BFE25D003D655D00 extended partition 2 partition table (14346045 sector), create the commence and size of the G disk 00000000070000003F000000FE645D00 to the D disk partition table (sector 0), create the parameters Enter, as shown inside the figure below, visit the partition table from the extended partition 1 (8193150 sector) and create the parameters in the two partition tables. As shown in the following figure, write the parameters from the G disk in the partition table of your extended partition 2 (sector 14346045). , Save and restart the computer. Right-click on My Computer---Management---Disk Management and discover that there is no drive letter. Right-click the mouse and click 'Change Drive Letter and Path' to pop up the leader, pick Add----OK to open my computer system and discover that the disks are back, ( *^__^*)...plus the data are all in Haha Now introduce the second technique, use software program to recover. I use diskgen. Initially delete all of the disks just now, and simulate the failure. Now it truly is the same because the beginning. Open the software program diskgenius.exe, this interface seems, pick the second tough disk, click the search partition to seem the wizard, the configuration is as follows, the default should be to uncover a partition, choose to keep the second, keep the third, hold the fourth, preserve the size and In the event the original is the similar, pick OK after which select Apply to change the pop-up dialog, pick mbr, and confirm right-click on my pc --- management --- disk management, and find that the drive letters are all there. Appear at my personal computer, and also the information inside is all there. Ok, both of them are introduced. Do you feel the second one is exceptionally easy?
