In many data recovery cases, users will get many invalid or corrupted files in the recovered folders. It’s not good or not professional to send all these recovered folders to the final clients(PC users asking for data recovery).

When patient drives have many bad sectors or weak heads or scratched surfaces or when the patient drives have many fragmented files and common data recovery software cannot recover and restructure all fragmented files and the recovered files could not be opened normally, users will get many invalid or corrupted files within these cases.

Dolphin DR Assistant Pro. helps a lot to detect all invalid files or corrupted files quickly and delete them quickly.

Invalid files contain the following items:

01: Suffix contains tmp, tem, temp, Ink, etc;
02: Prefix contains ?, ~,etc;
03: File name contains ? ;
04: Detect and delete desktop.ini ;
05: Detect and delete thumbs.db

Content or File Header contains DEADDEAD;

All corrupted files will be put to one special folder DEAD_DEAD_DEAD.
Data recovery engineers use this function-‘Detect and Delete Invalid Files’ very frequently for their data recovery success.

Steps to Detect and Delete Invalid Files:

01: Select Path to detect and delete invalid files;
02: Click ‘Check’ to detect invalid files;
03: Click ‘Delete’ to delete invalid files.

Dolphin Data Lab has created one unique firmware repair and data recovery solution for Western Digital slow hard drives including the WD SMR hard drives. This new function is called ‘Adjust Adaptive Parameters’.

Western Digital HDD Slow Issue types:

01: Firmware slow-users can fix the corrupted firmware modules to fix the slow issue. DFL-WD HDD Repair Tool offers one-click slow fix solutions: Common>Common Repair>Slow Fix for traditional WD hard drives and DFL-DDP data recovery tool offers easy-to-use slow fix for WD SMR hard drives: DDP>Western Digital>Change Disk Configuration>Set the sector r/w response time.

02: Physical slow-users need to use the new data recovery solution to enhance the head r/w capabilities and make the drives read/write quickly. Menu path within DFL-WD hdd repair tool: Common>Adjust Adaptive Parameters

Please note: Some WD hard drives are full of bad sectors due to head corruption and users need to swap heads to fix and get lost data back.

Users can watch the video instruction here on how to use ‘Adjust Adaptive Parameters’ for data recovery without head swap.

Dolphin Data Lab has created one new Seagate hdd firmware repair function specially for fixing Seagate faulty hard drives with LED status.

For Seagate patient hard drives, users cannot enter F3 T> and cannot do anything further to repair the corrupted firmware modules if the hdd suffers LED failure. It is something like the bluescreen of the computers.

To fix the Seagate LED HDD, there’re several methods:

01: Short connect;
02: Hot swap;
03: Boot ROM write+Loader

Now we create the 4th new and easier method: Disable Subsystem of the SA and this is something like the ‘disable 411’ within WD hard drive firmware repair software, very easy to use and very helpful in many Seagate LED cases.

Users can open DFL Seagate HDD repair tool, enter the software, select ROM Operations>ROM Edit>Disable Subsystem

Next users just need to write new rom to HDD and then users can bypass the LED status, go to COM terminal and enter F3 T>, finally users need to write back the original rom after firmware repair.

Next users can open DFL-DDP data recovery software and get all the lost data back easily.
