My Lacie Drive Won T Show Up

LaCie External Hard Drive won't start up Thread. It did show that 450 GB of the drive was taken up. So if the files could have been corrupt, would that still show. Therefore, if an externalhard drive won't mount on Mac, it means the system gets into trouble in recognizing the file system or other information of this hard drive. Conclusion: If your external hard drive is not mounting on your Mac, don't panic. Most of the time, you are going to fix this disk problem with the solutions above. When I connect the Lacie to the PC with Disk1, windows won't pick it up (does not show in device Manager or My computer), but it can be used using the Firewire400. When I connect it to the PC with Disk2 the USB2 connection works normally. Curious thing is that I also have a Seagate USB2 external drive and it works perfectly with Disk1. LaCie drives conserve power by spinning down when you set your computer to sleep mode. When the computer awakes from sleep mode, the drive may not have enough time.

Why Can't See Files in External Hard Drive & How to Solve

I find files missing from external hard drive become a frequently discussed issue in many forums. So there must be some ideas that catch the point.

Based on this, I decide to make a list of the possible reasons and useful suggestions for users to refer to. Here, I have summarized 4 main causes as well as the solutions in Windows 7 through internet searching and actual operations.

4 Causes That Can Be Fixed Directly in Windows

1. The files are hidden.
2. There are file system errors.
3. The 'CheckedValue' is suffering from virus infection.
4. The mirror image in memory is damaged.

Possible cause 1 – the files are hidden.

Sometimes, the files are not really missing from external hard drive; they're just hidden and not being shown. Here are 4 solutions to unhide them.

Solution 1:

1. Type cmd to the search box and press Enter.
2. Right click on the cmd.exe and select Run as administrator.
3. Input DIR/A x:-s (x refers to the drive letter of your external hard drive). The meaning of this command is: list the non-system files in x: drive.
4. If this command returns nothing, it means your folder has been marked as protected system files, and then you can refer to the second solution.

Solution 2: check whether the files are endowed with system property.

1. Run control folders, or go to Control Panel and Appearance and Personalization.
2. You can see the window Folder Options.
3. In view tab, check show hidden files, folders, and drives and uncheck Hide protected operating system files (Recommended).
4. Then check whether the files/folders are there.

Solution 3:

1. If your files keep missing from the external hard d drive, run cmd and press Enter key.
2. Then, if the hard drive letter is O:, you should enter this command: attrib -h -r -s /s /d o:*.*.
3. Finally, check if the real files will be showed.

Solution 4:

If all solutions above failed, try the following process which is most complex:

1. Run cmd.
2. Type the location of the external hard drive. Example: 'd:', 'e:', 'f:', etc.
3. Type dir /ah. You will now see the files/folders with hidden attributes.
4. Type attrib [name of file/folder] -r -a -s -h.
5. You should repeatedly type dir /ah after un-hiding some files/folders so you know if the files/folders are now appearing or hiding.
6. Finally check your external hard drives, all data should be there.

Please note:

• If you're going to unhide files, you should type the whole name plus the expanded-name. Example for file named party: attrib party.jpg -r -a -s -h.
• If you have folder names with 6 characters or more, type the first 6 characters followed by '~1'. Example for folder named birthday: attrib birthd~1 -r -a -s -h.

Possible cause 2 – there are file system errors.

In some cases, the files may be not showing in external hard drive because the file system is corrupted or because it doesn't contain a recognized file system. At this time, you had better recover data from external hard drive firstly.

Here's how to confirm:

1. Right click on the external hard drive.
2. Choose Properties.
3. Select Tools tab and click on the Check now button.
4. Check Automatically fix file system errors from the pop-up window.
5. Click on the Start button to begin and wait for the process.

Possible cause 3 – 'CheckedValue' is suffering from virus infection.

Here's how to fix:

1. Run Regedit.
2. Then, follow this route in Registry Editor: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerAdvancedFolderHiddenSHOWAL.
3. Check whether the data value of CheckedValue is 1.
4. If NOT, delete CheckedValue, create a new DWOR in the blank and rename it as CheckedValue. After that, modify the value data as 1.

Possible cause 4 – the mirror image in memory is damaged.

Sometimes the mirror image in memory is damaged and the operating system does not respond a timely refresh, which happens by chance.

How to fix: restart the computer and then reconnect the external hard drive to check if the actual files are shown.

That's all for the solutions. In fact, each solution has helped many users get rid of files not showing in external hard drive problem, and I also hope they are helpful for you.
