In any Windows computer, running chkdsk often fixes file system related hard drive issues. But there have been lots of instances in which chkdsk has failed because of its limited capabilities. If the present hard drive problems do not allow you to boot the computer, all the stored data becomes inaccessible. These are some situations when you might need to use a Hard Drive Recovery Software, especially when there is no or invalid data backup available.

After a general description, here is a specific, real-time scenario that might occur and render your hard drive data inaccessible by all means. Consider a case when you use a Windows run computer that fails to boot with an unmountable boot volume or similar error. Such problems require you to enter Recovery Console and run chkdsk from its command-prompt. But when you do so, it doesn't succeed while giving you the below mentioned error message on screen:

“The volume appears to contain one or more unrecoverable problems”

The depicted problem can be the result of both software and hardware errors- usually the software errors.

Methods to Solve

In some cases, the above issue can occur because of Windows issues - missing or corrupt system files. If this is the case, you should first try Windows repair install and if repair doesn't seem to work, try clean reinstall . To restore deleted data, you need to use your latest data backup. A corrupt MBR partition table, or boot sector is also known to cause similar kind of issues. For repair, you need to enter Recovery Console and run commands like, fixmbr and/or fixboot. In worst cases, a clean reinstall is the last option.

During any of the cases discussed above, if you fall short of restoring deleted data from backup, it is recommended to use a Hard Drive Recovery software.
