1. HARD DISK STORAGE BASIC
- Introduction to Storage Device (Types of Hard disk, Models, Types of Converter.)
- Introduction to Storage Device (Types of Hard disk, Models, Types of Converter.)
- Hard disk families, identify, (wd, Seagate, Samsung, Toshiba Hitachi etc)
- Hard Disk Data recovery common problems, with fault identify (logical, physical, PCB, mechanical and firmware problems )
- Logical Common Problem (Formatted, MBR error, boot sector error, partition not shown)
- PCB Common Problems (Dead, No spin up, Shorting, Burned Component, Motor dead)
- Physical Common Problems (Head voice, Scratch voice, Motor damage, head stuck, Preamp)
- Firmware Common Problems (Model not shown, slow, bad sector, wrong model, not detect, defect list, plist, glist, etc)
- Ransom ware virus ( how attach , types of virus, effect on files, solution )
- Understanding hard disk structure (head, sector, cluster, track, cylinder, CHS, LBA, Zone BIT,)
- Internal Parts of Hard Disk (spindle motor, arm, head, filter, Heater, Gimbal, Platter, Clamp)
- Understand how data stored in hard disk (Sector, cluster track, cylinder, FAT, NTFS, MBR, MFT, boot sector)
- Working concept of Format, Partition & Computer booting process, Service Area, User Area
- List of Common software use for recovery (files recovery, mbr repair, partition recovery, fast copy, zero fill, etc)
- Formatted and deleted disk
2. LOGICAL DATA RECOVERY SOFTWARE
-
- Data recovery Software used for different problems, (Deleted partition recovery, Formatted data recovery, MBR repair, Deleted files recovery, Different software used idea)
- Pen drive and Memory card logically data recovery concept

- Common software Used
- Memory card data recovery practice
- Pen drive data recovery practical
- Hard disk data recovery practice
