Only if the DVR system has the channels info stored, they can be found out and listed. For formatted or deleted videos, users can use the Deep Scan option within Dolphin DVR data recovery software and get lost videos back by dates.

This is one patient HDD firmware repair and data recovery case study from one DFL user in Indonesia.
Patient HDD ID: Seagate ST9500325AS Wyatt 3C
Symptom: Capacity 0 with the following com terminal error messages:

‘Rst 0x08M
RW cmd 0002 req = 89 3E 00 00 17 02 00 00 00 00 00 00 08 8C 08 00 87 97 09 00 08 8C 08 00

opts = 00001121’

To fix the capacity 0 and RW Err, users need to backup rom and firmware modules and sys files and next the engineer got partial sector access issue.

To fix the partial sector access issue for this patient hdd, users need to use the partial sector access auto fix solution, just one click to fix by DFL Seagate hdd repair tool.

Finally the data area was fully accessed by DFL-DDP data recovery equipment.
