I am in dire need of your help. Not ten minutes ago , I lost access to my brand new 2 TB drive. I have all of my data on it. this is what I did. I bought this drive to upgrade from a 1.5 TB drive and successfully cloned the 1.5 TB drive to the 2.0 TB drive. I have been using the 2.0 TB drive for about three weeks without any problems. Both the 1.5 and the 2.0 TB drives were mounted on external sata enclosures. today, I wanted to format the 1.5 TB because I was satisfied that the 2.0 TB was stable. What happened next will astound you. I properly ejected the working 2.0 Tb drive from the windows open devices and printer icon on the far right corner of my screen. I always properly eject and wait 60 seconds before I turn off the external enclosure. After the 60 second wait period , i mounted the 1.5 TB into the external enclosure (it can handle two HDD's). Now both drives were mounted and I turned the external enclosure on. To my surprise and utter dismay both drives came up with drive letters F: and G: respectively,but I couldn't get into the drive via explorer. The error I received from both drives is that they were both unreadable and corrupt. I pooped myself. I got on line and looked for a solution. I found that all I had to do is go to the dos prompt and perform a chkdsk /f f: and then I had to go to the security tab and take ownership of the drive and viola , the 1.5 TB came up and I can access all my data again. Since the same condition exist with the 2.0 TB drive , I performed the same task but the chkdsk failed promptly with the following error:
Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.
C:\WINDOWS\system32>chkdsk /f g:
The type of the file system is NTFS.
The first NTFS boot sector is unreadable or corrupt.
Reading second NTFS boot sector instead.
Unable to determine volume version and state. CHKDSK aborted.
I am concerned, as I have added three weeks of data to this drive, so it would be nice to get it back. I believe to be as simple as fixing the mbr, but I will take your advise in trying to get my drive back. If the 1.5 came up , why not the 2.0. Is it because the 2.0 drive is hitting the limit of NTFS and needs to be formated as GPT?? I don't know. Please advise.
