How to Edit File Names After Raw Recovery

,

Raw recovery is very commonly used in all data recovery labs. In many data recovery cases, the faulty hard drives may have bad sectors, MFT corruption, scratches, etc and therefore, users can only recover the lost data by file types, that’s raw recovery.

All the recovered files don’t have real names and they are recovered in raw status and it’s not possible for users to recognize the wanted files from thousands of files or even more.

So what’s the best solution to fix these raw files without correct names?
Dolphin Data Recovery Assistant Pro. comes as the best solution with one software module called ‘File Rename’ and users can edit all these files easily with proper names.

The following are two video case studies:

How to rename raw files for best recovery success：

How to Find out Lost Documents with Real Names:

Steps to Edit the Raw Files with False Names

1, Adjust the File Rename settings to rename by date, sheet, content or file size;
2, Select the folder containing raw files with false names;
3, Check files;
4, Rename files and Done.

WD SMR HDD All Sectors 0 Sector Mark

,

Within the new DFL-DDP data recovery software, users can set sector mark easily for ‘all sectors 0’ areas. This feature is very helpful to get lost data from WD SMR hard drives.

‘All sectors 0’ failure has two situations:

The 0 sectors have data and the 0 sectors don’t have data. It’s normal many sectors are 0, empty and no data at all;
For WD SMR hard drives, many 0 sectors may contain real data which is controlled by the dynamic translator module 190.

In real cases, it’s not possible to tell which 0 sectors have data or not and therefore, users need to mark these sectors and put them aside.

Next the engineer ticked the WD SMR all sectors 0 mark, went to set up head map, image good heads, image good sectors first or load 190 automatically to image; After the first round of image, users can edit the disk image settings, for example change the read block size to smaller, disable pre-read, change to lower-rated data transfer mode, etc. After these settings, users can image all the 0 sectors again.

By above method, users can definitely get more data back from the WD SMR hard drives.

Seagate 24 1A sEDU HDD Firmware Repair and Data Recovery

,

Seagate 24 1A and sEDU data recovery cases are common in Seagate rosewood LM series, all data recovery engineers can use DFL Seagate hdd repair tool and DFL-DDP data recovery equipment to get the lost data back from these patient drives suffering 24 1A or sEDU failure.

24 1A or sEDU is the error indication shown in the hex area and when the hex data contains these errors, the files cannot be opened successfully.

The key to fix Seagate 24 1A or sEDU cases is to backup the original NGlist, translator and primary defect list.

What causes these 24 1A or sEDU errors?

These errors come after translator regeneration, users need to be very careful when trying to regenerate translator, specially for rosewood EB01 hard drives. Sometimes if there’re some bad sectors, the 24 1A or sEDU errors may not be fixed completely.

Weak heads cause 24 1A or sEDU errors too. This kind of case has usually single weak head but the patient hdd is still detected correctly. The hdd data area can be accessed but slow and when trying to view the hex area, users can see 24 1A or sEDU indicators and these sectors are not correct and files of these sectors cannot be opened successfully.

With original NGLIST, it’s not difficult to fix the 24 1A or sEDU issue by DFL Seagate hdd repair tool. For weak heads causing the 24 1A or sEDU errors, users usually need to swap heads by Seagate LM Head Replacement Tool to get all data. Before head swap, users can check the imaged data, sometimes the 24 1A or sEDU files may be not important at all and then no need to swap heads.

Within the new DFL-DDP data recovery software, users can simply set the 241A or sEDU sector mark to start the image and image all possible sectors before processing the 24 1A or sEDU repair. After repair, users just need to image the 24 1A or sEDU sectors again.
