Diskcheck and format

[jeccross]

Hi, I have a LS-WXLB16 2 x 1tb drive and found the red light flashing and the web access page saying 1 drive had an error.  I ran a disk check and the red error light is now indicating that it is formatting, although the drive isn't making much noise.  However it has now been running for over 4 days.  Is it normal for it to take this long?  Should I keep waiting or interrupt the process somehow?

 

I presume it will only be formatting the disk with the error?

 

Thanks
