Files Are Missing after Check Disk

When encountering the "one of your disks needs to be checked for consistency" error, many users are prone to let the disk check run in order to fix the problems they may think exist on their computer disk. Sometimes, the check process can be finished smoothly, but sometimes, it can't be done. Well, does it mean everything goes fine when the check disk is finished completely and you start the computer successfully? Of course not!

Please look at this case:

"Hi, guys. Just got this error when I switched on my computer: one of your disks needs to be checked for consistency. (G:) The disk in question is one of the two partitions (F: and G:) of an old HD that I just slotted into my new system 3 days ago. It was working fine, and able to browse files on it fine until earlier. I let the chkdsk run, and it found some errors and orphaned files etc.

Now when I'm in Windows, under My Computer, F: shows with details of space etc., and G: is there but doesn't show details. What do you suggest I do next? My OS is in my new drive, so it isn't a problem. This old drive has been with me for 7 years, and I'm wondering if it could be failing. Also, I was shifting the CPU earlier, could it have been due to that?

EDIT: Just tried accessing G: in My Computer, and after the green bar filled up for a while, a message popped up saying: G: needs to be formatted before use. Do you want to format it now? I clicked No, and then an error message popped up saying: G: is not accessible. Data Error: Cyclic Redundancy Check."

Shank said that he was in Windows and found that G: didn't show details. When he tried accessing G:, the message popped up, saying that G: needs to be formatted before use. In this case, he loses access to all the files saved on G:, obviously. If any of those files are important to him, he will definitely make every effort to recover data after check disk.

Considering this, we decide to teach you how to recover data after CHKDSK.

1. Estimate the total size of files you need to recover. If it is no more than 1GB, just go to download MiniTool Power Data Recovery Free Edition V7.0; if it is more than 1GB, you should rely on an advanced edition (we recommend Personal Edition if you have no special requirements in usage environment).

2. Run the setup program to install the data recovery software to the computer. Then, launch it to choose a proper functional module to recover data according to needs (you should copy & paste your license key into the text box to register first if you choose the advanced edition).

3. Choose the certain module by clicking on it. For instance, to recover data from G:, the inaccessible drive, in above case, you should click on "Damaged Partition Recovery". By putting cursor onto it, you'll find it's designed for "deep scan, recover data from damaged, RAW or formatted partitions."

4. Select the target partition to scan from the list in the software interface. Then, click on the "Full Scan" button in the lower right corner to start detecting files in that partition.

Press Any Key to Skip Disk Checking Not Working

When Windows asks to check disk for consistency, there are also some people choose to reject this request. They prefer to press any key to skip the disk checking, as prompt said. Yet, how will you respond when one of your disks needs to be checked for consistency stuck? Are you afraid of losing all the data saved on the current computer? Please don't be, since we have a way to help you recover data from the corrupted internal hard drive.

Let's see a specific case first:

"I am currently having an issue. Whenever I start up my PC, the following message appears:
Checking file system on C:.
The type of the file system is NTFS.
Volume label is ACER.
One of your disks needs to be checked for consistency. You may cancel the disk check, but it is strongly recommended that you continue. To skip disk checking, press any key within 1 second(s).

This message counts down to 1 second and freezes. I tried leaving it for 4 hours today as I went to school. Came home, and it was still on this screen. As I said, every time I start up my computer, this message appears and I am forced to force shut down the computer if I do not hit a key in time. I am wondering if there is an alternative and recommended option to run this disk check to avoid skipping this message on every startup."

- put forward by Sean1082 on SevenForums

Sean said that when the message counted down to 1 second, the process froze. Then, he left the computer opening. But when he came home from school 4 hours later, the computer was still stuck on the same screen. And every time when he starts up the computer, the same message appears. In cases like this, people will be wondering how they can avoid the auto check on startup and how to recover files after check disk was stuck.

Now, we focus on how to restore data from internal hard drive:

1. How to recover data from non-booting computer? You need a bootable edition of MiniTool Power Data Recovery. Of course, you also need to choose a license type for it. The free edition is not suitable anymore in this case since it is only able to scan the files for you, not recover. So you need to choose from Personal License, Commercial License, Enterprise License and Technician License. (We'll take Personal License as an example in the rest steps; other license types are basically the same)

2. Save the bootable edition to another computer that works fine. Then, connect a USB flash drive to or insert a CD/DVD into the computer and run the program to make a boot disk according to prompts.

note Please make sure that there is no file you need on the USB flash drive or CD/DVD because when you click on the "Next" button in the following interface a warning window will show up, informing you that the selected device will be formatted and all the data on it will be destroyed.

3. When you see the successfully prompt window, you should unplug your device from the computer as suggested. Then, you should connect this boot disk to the computer which requires disk check for consistency.

4. Restart your computer and press corresponding button to enter the BIOS. Then, change the boot order of your computer to make this boot disk the first boot device. After that, exit BIOS and save changes.

5. After a while, you'll see the picture shown below. At this time, you may choose "MiniTool Power Data Recovery V7.0" directly or wait for a few seconds for the automatic boot.

6. Then, you'll be brought to the main window of MiniTool Power Data Recovery Boot Disk, which is almost the same to the main window of the non-bootable edition (the only difference is that the boot disk has only four functional modules, "CD/DVD Recovery" is not included). Now, you should jump to the second step in above "Files Are Missing after Check Disk" part and finish the rest steps shown in this part.
