Partition table is missing, hard disk partition table is missing

Run the diskgenius software (**The address is in the references), find your hard disk (pay attention to the hard disk model and capacity), right-click on it, select Search for lost partitions (rebuild partition table), and then you will find your previous partition, after the search is completed, right-click on the hard disk again, select Save Partition Table, and then open my computer, your previous partition should come out, and the data is the same as before, you can also use this software to partition, delete the original partition first, Then just create it, it's very simple. Good luck!

PQ Disk Partition Or right-click on My Computer Manage Disk Management Right-click 1T hard disk to create.

You can use an optical drive, use a system disk partition, but after dividing the hard disk, the things are gone.

The version of Disk Genius (DiskGen) has the ability to repair partition tables. The effect is not bad. It takes an estimated hour.

2.There is a special one for repairing partition tables, and it is also a software under DOS, and the effect is great. But if you don't know much about SCSI hard drives, you can't do it.

3.Manual recovery.

The 0th column of the hard disk, 0 side, area 1, CHS format (0, 0, 1), the LBA address is 0, which stores the master boot record (that is, MBR), the last 66 bytes of the MBR is the partition table, except for the last two bytes 55 AA is the end mark, and the remaining 64 bytes are the hard disk partition table. The convention can only have four partitions, so each partition entry is 16 bytes.

Byte definitions: boot type (1), start chs (3), partition format (1), stop chs (3), start liba or interpreted as how many sectors there are before, what really means should be the offset relative to this MBR (4), partition size (4).

Here, chs, the first byte is the disk (magnetic head number), the first 6 bits of the second byte are the sector code, and the last 10 bits are the cylinder number, now you know why the single partition is the largest, 1024*64*255.

Knowing this is not enough. Then analyzed, there are only four partition entries in the MBR, so there can only be four primary partitions, in order to expand, it must be in the form of a linked list, and the last primary partition becomes an extended partition, in which the recorded LBA starts to point to a certain sector, and the function of this sector is equivalent to another virtual MBR, where there is a partition table.

In addition, in the first partition, the size of the partition is recorded, which is the key to our manual recovery. Software.

You'll have to be patient

Diskgen is a good one

There are many reasons why partitioned tables are missing, but there are four common problems:

1. Wrong operation. When the user reinstalls the system or restores the system, the recovery partition is selected as the recovery disk, and after the completion of the Zen Yu roll, the entire hard disk becomes a C disk, and all other disks are lost;

2. Software conflicts. When a user uses a tool such as Partition Assistant to merge partitions into a virtual hole, due to the exclusivity or permission of other software to the hard disk, the partition operation is forced to break in the middle of the partition operation, and the partition table will be confused or rewritten, resulting in the loss of the partition table.

3. Power off. When the user uses it normally, due to the sudden power failure, it will cause great damage to the hard disk, such as data disorder, partition disorder or bad sector of the hard disk, which will cause the loss of partition table.

Tools Raw materials.

Computer. Method steps.

1. First of all, click the "Start" icon, click "Run", and enter "cmd".

2. Enter the command prompt interface, enter "chkdsk f h:" according to the drive letter corresponding to the U disk, and press enter.

3. Click "Start Check", pop and dismantle the Qing out of the window, click "Yes", and repair the partition disk through the tourism chkdsk command, and then you can open the partition disk normally for access and operation.

We must have encountered the problem of losing disk partitions from computers at work, and many of us will choose to format the disk or create another disk partition when encountering this situation. Actually, this is not the right thing to do, partition loss data recovery we can use like ourselves don't just operate.

Many people do not understand how to recover data from partition loss, resulting in the wrong disk partition or the recovery of the disk partition, but the files in the disk have been damaged or lost.

What to do after hard drive partition loss? If you need to recover data after partition loss, you should stop writing new data immediately, and choose the right method to recover it according to the problem analysis, so as to avoid the wrong operation destroying the data again and increasing the difficulty of recovering data.

How to recover data from lost hard drive partition? The operating system does not have the capability to recover lost data. If you want to recover missing data from a hard drive partition, you need to use a third-party data recovery software. Let's take a look at how it works.

Select the "Hard Disk Partition Disappears" feature.

Step 2: If the software has found the lost partition, click on the corresponding partition to recover.

If the missing partition in the list is not the one you want to recover, you can click Scan Lost Partition to scan the lost partition from your hard drive. When the dialog box for the lost partition pops up, select the hard drive from which the partition was lost and click Next to start scanning.

Step 3: After finding the lost partition, select the file type you are looking for, and then click Next to scan the data in the lost partition that matches the selected file type.

Step 4, when all the files are scanned, you can find the files you want to recover according to the file type, path, file name, etc., if it is a common file type, you can click to preview it, then select the data you want to recover, click "Recover" to restore it to the path you choose.

Hello, all kinds of software are developed for a purpose, and sometimes when you are not sure about using a certain function of a certain software to accomplish a certain task or need, it will help you instead.

I once used the partition table doctor to repair the partition, and as a result, the C and F drives became "free space", and I didn't back up the important data in the hard drive at that time, so I searched everywhere on the Internet for data recovery software, and it took me a few hours to recover the data.

So you don't have to trust the functionality of a software too much, it is recommended that you make a backup of your important data first, and then try to repair the partition using the partition table doctor.

If you can't back up due to the wrong partition location during backup, you can use data recovery software to restore important data and back it up before using Partition Doctor, recommend data recovery software to you: DiskGenius It's best not to use "Data Recovery Wizard" because when you spend a few hours recovering data, you will find that there is a charge in the end, and at first you don't know that it is charged, I was fooled once. Data recovery takes a lot of time to be patient.

Good luck, don't be as miserable as me, tossed by hard drive data.

Hope it helps.

You can take the hard drive off and hook it up on another computer.
