It has been revealed that any particular threat/computer virus/malware atleast can disable a hard drive temporarily. Means it itself alone is not capable to damage the drive physically or completely disable hard drive to the extent where it can’t be repaired. However, it’s quite difficult to remove some highly perilous or destructive threat like boot-sector virus in specie to the non technical people. The reality is that, it can damage or corrupt the data saved on the hard drive, but not so much capable, that it can destroy the device itself.
Virus Disable Hard Drive, Not Break It
Actually, computer virus is malicious programs that after getting settle down into the targeted computer can executed, replicates by inserting copies of itself in order to spread into the entire PC along with data files, computer programs or the boot sectors of the hard drive and this area has been considered as “infected”. Further, it do have capability to perform some distrustful activities on the background one after another and can disable whole operating system making the PC just a useless device. In most of the cases, it has been seen that some virus that has affected the hard drive files can be eliminated by hard drive reformatting. Means you have to delete all data and after doing that also, there is still a chance of having that malicious program on the file backup.

Boot-sector viruses has been considered as one of the most vicious and damaging virus whose removal is somewhat more difficult as compared to other virus. Usually, it infects the computer system by copying code either to the boot sector on a floppy disk or the partition table on the hard disk. It automatically get loaded into the memory each time when PC startup and will infect any non-infected disk accessed by the system. Examples of boot- sector viruses are Michelangelo and Stoned. This threat can infects crucial part of the hard drive, even to the those that holds operating system loading information and file allocation tables which is being used by the hard drive in order to locate device stored information. Boot-sector viruses stored on different section of the hard drive disk and that’s why, it can survive a hard-drive reformat. It can be obliterated either by emptying or clearing the boot sector or through using a powerful and effective removal tool that has capability to rebuilt the boot sector.
Presumptive Firmware Damage
As to the Computerworld, It has been said by Western Digital Vice President Gary that it is possible to craft a virus that do have capability to both damage a particular hard drive’s firmware and can disable the device. The firmware-damaging virus is an hypothetical creation which is quite effortful to craft it. Further, it has to be tailor-coded for each particular hard drive and lacks actuational intent as because it instead of stealing information, may disable computer. But, firmware-damaging virus still cannot disable a hard drive permanently as it can be flashed and restored to its real state.
It has been believe of various heads that a virus could devote to an current action that may result hard drive break. In case of having insufficient RAM in order to fulfill demands of all the programs, PC fall back on the hard drive virtual memory extension. And at some point of time, when hard drive memory become insufficient, PC enroll in disk thrashing which means continuous reading and writing information of the hard drive, that resources hardware to wear down. Dissimilar to a virus, it would cause disk disk thrashing, but having numerous malware in PC that’s already disk thrashing can increase severity of the issue and dispenses to the hard-drive wear.
