Data loss in DVR units can occur due to multiple reasons
Before we move on to DVR data recovery more in-depth, a few words on why data loss in DVR units can occur. Next to each, we’ll also list the recommended course of action to take in each of these scenarios.
Even though your first instinct may tell you to dry the DVR unit due to it having come into contact with water, DO NOT dry it!
Attempting to do so would accomplish nothing but subject it to further damage, which can greatly reduce your chances of successful HDD data recovery.
The solution, although not ideal, is to actually keep the hard drive wet.
If the DVR unit gets damaged by fire, one of the key points to remember is to avoid trying to take it apart without professional assistance, else you might cause irreversible data loss.
Although it’s possible to salvage it, this requires specialized data recovery equipment.
Out of everything, data loss due to accidental deletion is arguably one of the most salvageable causes of data loss. Upon normal deletion, the data itself doesn’t get erased, merely “unlinked” from the data structure, so the operating system no longer recognizes the data is actually written on it.
The good news is unless the data was shredded, it’s actually possible to recover it with the help of DVR and external drive recovery software such as SVR for HikVision by SalvationDATA.
It will easily help you recover these files even if they have been misformatted, deleted, or overwritten.
A common reason data might corrupt is when detaching the SD card too soon when copying data from or to it so it doesn’t get a chance to be saved properly.
Of course, someone might even decide to format an SD card, either due to the need to make more space or as an attempt to conceal crucial evidence.
In both of these cases, SVR for HikVision can help you restore the data that’s on it.
Malware is one of the most potent cyber security threats that can do all sorts of things:
- Install a backdoor
- Steal data
- Delete data
- Encrypt data
- Cause performance issues
- Monitor your actions
Some nefarious forms of malware are so potent in their design that they either destroy your data on purpose or make it inaccessible. Although most DVR units are running their own operating systems (usually a Linux distro), malware can theoretically still be a potential cause of data loss.
Sometimes, a DVR unit can start failing due to physical damage or wear and tear. In case you hear any strange-sounding noises coming from the unit, this is usually a sign that it’s going to need professional repairs.
Trying to repair it on your own is NOT recommended, as this introduces an unnecessary risk of permanent data loss.
In layman’s terms, a bad sector is a part of the hard drive that has been permanently damaged. If you suspect you’re dealing with bad sectors, it’s essential to use a professional computer data recovery software such as DRS by SalvationDATA.
It comes with built-in scan modes that will detect whether there are any bad sectors on the drive. With the help of disk imaging, it will help you recover the data affected. Plus, It supports a wide range of hard drive brands.
DRS comes with several disk diagnostics, file recovery, file carving, disk imaging, and firmware recovery features.
