ST1000DM003 ST1000DX001 Damaged Heads or Platter Damaged

,

The following is one email from one DFL user in Germany asking for the compatibility between two Seagate hard drives, one of which requires head swap.

‘DONOR is ST1000DX001
Patient HDD: ST1000DM003

Hello,

i have here a Seagate ST1000DM003 – Drop down failure.

In first test i can see error message = damaged heads / and may be platter damaged

FAIL Servo Op=0100 Resp=0003
ResponseFrame EC40 0046 03B2 4900 0008 0000 0000 0000 0966 0000 0000 0000 0000 0000 0000 0000 57D1 F98F FFFF 2000 2412 0000 0000 4947 0000 4947 0000 007F 0000 0020 0012 0004 0000
FAIL Servo Op=0100 Resp=0003

I have only one donor HDD – ST1000DX001 and i know many people change heads between different hdds
and the preamp is the same.

Question: should i change the heads without create adaptive rom? (DM/DX possible !?)
or must i create a adaptive rom?

Or does it make no sense to swap the heads, what is your recommendation?

Patient: ST1000DM003 – 2 Heads
Preamp: B2 03
S/N: Z1D
PN: 9YN162
FW: NDP3
SITE: TK
Family: Grenada

Donor: ST1000DX001 – 2 Heads
Preamp: B2 03
S/N: Z1D
PN: 9YN162
FW: NDP
SITE: TK’
Family: Grenada”

For Seagate hard drive head swap, users need to check the preamp type, family, PCB number and sometimes head map, for some drives, even they have the same model number, they may have different head map.

After head swap, if the drive clicks, users need to create adaptive rom and write adaptive rom and try again. For the head swap cases, it’s very important for users to air blow the platters and the hdd inner parts and also need to check the surfaces carefully.

Tools required to fix above cases:

DFL Seagate hdd firmware repair tool
DFL DDP data recovery equipment
Seagate hdd head replacement tool

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.
