Some beginners in data recovery field would like to ask such one question-‘Do the head combs I buy from you fix all my physical recovery cases?’ I am sorry but the answer is no.
There’re no universal head combs or tools which can be used for all hard drives because each type of drives have different design and structure, they have different head and platter numbers, they have different data storage technologies.
Sometimes it’s more important for users to have proper knowledge to diagnose the failure reasons and then use the correct solution to fix the physical data recovery cases.
For physical cases, the following are very common cases:
The heads are dirty or contaminated and users need to use distilled water to clean them. If the drives are drowned by a flood, users need also ultrasonic cleaner with distilled water, never power on the drive until you have cleaned and dried the drowned hdd;
Heads’ stiction is another common case on different drives and users need very proper skills and forces to spin the platter and uninstall the heads with suitable head combs;
Single head damage or multiple heads damage, it’s a must users need to use the right head combs to swap heads;
Motor stuck: users need either to swap platters or release the spindle motor;
Platter scratches: this one has very small chance of getting data recovered, depending on how severe the platters are scratched. It’s better users have one microscope to watch the platter and heads in the clean room.
The head combs are used in all above cases but it doesn’t mean you can get a success in the recovery cases because your skills of operations, your donor quality, your operation environment can all affect the final result.
The head combs are designed to work with the common drives we saw in the market, but it doesn’t mean they support all cases, and the support list is clearly explaining what the head combs support.
We hope above answers the question clearly.
