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.

WD SMR 2060-810035 Spyglass II HDD Repair and Data Recovery Steps

,

WD SMR 2060-810035 Spyglass II HDDs have both MCU lock and SED lock. To repair firmware corruption and recover lost data, users need to fix the MCU lock first: swap with special 2060-810035 firmware unlock PCB or writing unlock rom to bypass the MCU lock by DFL-WD hdd repair tool.

Please note: not all 810035 PCBs support MCU lock bypass by unlock ROM.

Most common HDD failures for WD SMR 2060-810035 Spyglass II HDDs:

The data area is not accessed;
The data area is full of 0000;
The drive is undetected due to 190 corruption;
Physical head damage.

Most common functions and solutions used in repairing and recovering WD SMR hard drives:

Read/write ROM by HDD ROM Chip Pin Reader;
Generate unlock ROM by DFL WD hdd repair tool;
Sort nodes within module 190 by LBA/tree;
Scan missing nodes;
Delete overlapped nodes/wrong nodes;
Repair wrong nodes, etc.

Users can save all the modification to one new module 190 and then users can write the new module 190 or load the module 190 or T2data to RAM by DFL-DDP data recovery equipment for immediate data recovery.

WD SMR HDD WD20EZAZ 810011 Data Recovery Case by DFL User in Sri Lanka

,

This data recovery case study is shared by one of our experienced, smart, friendly and kind users from Sri Lanka, his name is Dananjaya who offers very professional data recovery services in Sri Lanka.

HDD ID Information:
Patient drive: WD20EZAZ
PCB: 2060-810011

Reported symptoms
According to the drive owner, when he was copying wedding pictures to HDD, windows OS popup error massage called “not enough space”

HDD Repair and Recovery steps:

1.Once our user received the HDD, he checked. He found that when power on HDD, it spin up, but then two times’ clicking and power down. Like platter damage;
2.He tried to unlock, but same scenario. No modules showed, only power up, two clicks, power down;
3.So he guess it can be module damaged. But couldn’t power up. He used only pcb and disable module 02, module 411 and kernel mode. But same clicking;
4.He found a donor PCB with same microcode HDD. Then used patient PCB to donor for test, donor drive can be detected as normal;
5.He put donor to PAITENT HDD. Luckily the patient drive can be detected. But after 10 seconds, gave one click and went to busy status. Not responding;
6.He managed to power on and off till enter the inside of FW program;
7.He disabled module 02. After doing that HDD shows module and no clicking. But once enabling module 02, start clicking again. He had to disable again to get all modules;
8.He edited module 02 manually and write it SA. Fortunately no clicking, smoothly worked with HEX 00;
9.DFL repaired the corrupted module 190, he then wrote it to SA and load to RAM. “missing node function ” and “repair nodes function” which built in version 2.31 were used for this case;
10. Two partitions are displayed properly, the image speed is quite good, up to 150M per second.
