LaCie 2Big external hard drive error mounting problem

Asked By 10 points N/A Posted on -


I have a LaCie 2Big external hard drive. When I tried to access it this error came.

I tried shutting down my computer and unplugged the USB cable, turned it on then plugged it back in, but when I accessed it still it likes to show of its big error message with hint's that I don't even understand.

What should I do?

I don't know if this helps, my operating system is Linux.

Unable to mount LaCie 2Big

Error mounting: mount exited with exit code 12: Failed to read last sector (1953519615): Invalid argument

HINTS: Either the volume is a RAID/LDM but it wasn’t setup yet, or it was not setup correctly (e.g. by not using madams – build …), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount ‘/dev/sdc1’ doesn’t seem to have a valid NTFS. May be the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

There might be a problem with the driver related to your external hard drive. The connection driver might have been corrupt. 

Try to uninstall the driver related to the drive and restart your system. 

After restarting try to install the driver again and connect your hard drive.

This should solve your problem.

Thank you.

You might be using a Mac operating system, and one way to check this problem is locating if there are problems with your cable, or if the software associated with your device is damaged.

If the cable is damaged, replace it with a new thunderbolt cable.

If the software is damaged, reinstall it with the application software included with your device.

You need to check the drive for errors. Plug the external hard drive to a computer that runs on Windows. Start Windows Explorer then select “Computer.” Take note of the external drive’s drive letter. Next, press the Windows key then type without quotes “cmd” in the search field. Right-click “cmd.exe” in the search results then select “Run as administrator” to launch an elevated command prompt.

In the command prompt window, type the following command then hit Enter:

chkdsk /f [drive letter]

Replace “[drive letter]” with the drive letter of the external drive. For example:

chkdsk /f e:

If this doesn’t work, try downloading PC Tools Performance Toolkit. Once installed, start PC Tools then go to “Recovery” tab and click “Repair Drives.” On the next screen, select the drive you want to check. From the options, select “Surface Scan” and check “Perform on reboot.” Click “Start” then “Continue.” Exit PC Tools then restart the computer to begin the check.

The checking will be quite long depending on the size of the drive and the extent of the problem. If bad sectors were found, try repeating the scan a second time. Bad sectors are normal for hard drives and usually appear as the drive gets older. If bad sectors appear everywhere on the drive and the drive is quite old, it means you need to replace the drive with a new one.

If you need to partition your drive, you can use EaseUS Partition Master Home Edition.
