Hard disk partition RAW format is not accessible solution

  
        Problem feature:

Hard disk partition drive letter can not be accessed, file system shows RAW, not NTFS, used space, free space and capacity information are 0 bytes, double-click display "Cannot access C:, file or directory is corrupt and cannot be read"
Workaround:

Method one,
<

Right click on the RAW format drive letter, select the attribute, then select Security, delete the useless user, add your own user name, and then change the permissions. If there is no security option, you can right click on the NTFS format disk in the folder option (Open My Computer, select the Tools menu, and then select the folder option). Security options are displayed in the properties menu.
Method 2,

Go to the "Control Panel" and find the "Administrative Tools", open it, and open the "Local Security Policy". Open "Security Options", in the right window, find "Network Access: Share and Security Mode of Local Account" and change "Only Guest" to "Classic", exit back to my computer, right click on the D drive and find " The "Safe" tab, delete it garbled, and then add the user of this computer. Note: The first and second methods are for the NTFS format. Unfortunately, the hard disk I have encountered is just the FAT32 format.
Method 3, [
Note: This method restores the HD video file, the file resolution will be reduced and the audio file may not play.]
1. Use EasyRecovery Pro 6.06, select Data Recovery Advanced Recovery (select advanced option custom data recovery function);
2, select the drive letter that has become RAW format, click the advanced option in the lower corner; />
3. In the file system scan, select "NTFS" for the file system, click Advanced Scan, select "Advanced Options" in the lower right corner, and set the cluster size and data start position to 0;

4, click on the partition settings, use the MFT method (this must not be wrong); then determine;
5, click Next, start scanning the file system, and then wait, want It takes a long time and you have to be patient. Upon completion, you will find that you have found a NTFS drive letter, then click on the found drive letter to start scanning.
6. After the scan is complete, you will find all the files found, then click Restore. , select an available disk to save your recovered files;
7, finally formatted the problem disk to copy the recovered files back to OK Everything is intact. Note: The third method I tried was that the data can be recovered, but it took a long time, and I did not restore it according to the original file name when recovering. All file names were changed to file1? File100......, the file name changed, it didn't make much sense. I later saw a way to restore data on the Internet. I think this method may be really possible. First, make the RAW format hard disk use Ghost as the image file, and then use Ghost Explorer to restore the data.
Method 4:

I accidentally discovered a tool PTEDIT32.EXE (partition table editor) included with Norton PartitionMagic 8.0, just tried it. After opening, find the information of the corresponding partition, and compare it with other partition information, and find that there is a big difference. At this time, the information of the partition that is in error is modified according to the information of other partitions (the hard disk partition is different, so there is no standard. The parameters), you can resume the operation, so don't worry, it won't damage the data, save it after the modification, and you're done after restarting! Note: The first thing I think should be that the partition table is broken. The most important thing to think about rebuilding the partition table is to use Disk Genius (because I don't have PTEDIT32.EXE in my hand), in the toolbar of the menu. Select "Rebuild Partition Table" and Disk Genius will start searching and rebuilding the partition. Disk Geniusn will first search for the hidden sectors starting from 2 sectors for the 0 cylinder 0 head, looking for the partition table that has been moved by the virus. Next, search for the first sector of each head. The search process can be done in either "automatic" or "interactive" ways. Automatically retains every partition found, which is suitable for most situations. The interactive mode gives a prompt for each partition found, and the user chooses whether to keep it. When the partition table in the automatic mode reconstruction is incorrect, you can re-search in interactive mode. I did not succeed in rebuilding the partition table in either "automatic" or "interactive" ways.
Method 5:

First cp ~/.bash_history ~/cmd_history Back up the commands you have tried, and then find you in cmd_history What order was used?
Method 6:

Modify the drive letter method, change the RAW drive letter, if it is C, D, E, F, F It is a RAW drive letter, and you can restore it by changing F to E.

Right click on the disk and the security options are displayed in the properties menu.
