If you are searching for a decent and real data recovery service provider in Bangladesh, then you have come to the right place. I will tell you how to choose a data recovery service provider. It's for you, it's very important to read every line when you need to send your HDD to get your irreplaceable data recovered. You need to be very sure that your HDD is being handled by a Expert who is/are equipped with full facility. Your HDD could be suffering any type of problem, it needs to go through systematic and logical way with the usage of right tools. There is no room for mistakes in Data Recovery.
A decent/real data recovery firm will be equipped with the following equipment to deal your cases (Following Facilities only we have in Bangladesh so far):
1. HDD Surgery equipment/tools + Clean Chamber or Clean Room (ISO 5 Standard/Class 100 Clean Lab)
2. Data Extraction/Imaging Device (Software & Hardware Combined Device)
3. HDD Analysis & SA Re-Work Device (Software & Hardware Combined Device)
4. Several types of other instruments required to inspect damage HDD.
5. Certified Expert - Achieved Certificate of Excellence (Issued in 12th January 2015 after 8 years of continuous growth)
Without the facilities, only Software based recovery such as - deleted/formatted/virus attack etc.and/or at best some External PCB (Printed Circuit board) work is possible. In different cases, usage of software will not be able to access data area or if somehow can be accessed, the process will kill the drive or will degrade the drive more instead of recovery. Then when you bring your case to a decent/professional data recovery firm, actually your case is now more complex that increases your cost of recovery or not recoverable anymore.
It's found that, without the specified equipment & facilities, at best 22% cases can be dealt, in rest cases, either cases gets more damage because of software based retry or can't be dealt in any mean.
In investment basis, data recovery tools/technologies are expensive. The equipment/facilities we have been using is worth about 15 Lacks Taka. And it's increasing day by day to meet with latest model hard drives. So, we can deal 100% cases whenever it comes to HDD, we can deal 100% cases doesn't mean we can solve 100% cases, there are several cases will be irrecoverable even with full facilities we have because of several factors such as -
1, If the platters are severely scratched or we can see a large area of physical scratches and sometimes we call this one physical bad sectors, then your data is gone forever with the existing data recovery technologies and tools;
2, If the platters gets miss-alignment and get totally distorted , no way to recover;
3, If we cannot find a donor components or a donor drive, then tools and technologies are nothing;
4, If the data is overwritten or further damaged by the first party you send your drives to and these cases are mostly unrecoverable even if we may get the drives work again but data is permanently lost. etc.
A lot of firm/people are offering data recovery services without decent facilities. Only dealing some very basic jobs, in difficult cases, some of them are good and taking wise decision, they just stop playing with the HDD, also some of them can't take wise decision as of lack or experience/knowledge, they are still playing with the HDD, it's out of their imagination that they are making some irreversible damage, it's advised to the people for taking care of client HDD wisely as there is no room for mistakes in Data Recovery.
