External HDD Error: You Need to Format the Disk Before You Can Use It
Hi All-
Any insight in how to fix a drive that is giving an error of "You Need to Format the Disk Before You Can Use It"?
The HDD is a 1TB LaCie USB HDD formatted in FAT32 that I'm using on my Win7 Homer Premium (64bit) OS.
I'm using this drive using for file storage with my home photography business and it is critical that I recover data from it. I've had the drive for about 6-months and it worked great the entire time. Recently, I received an error message when I was backing everything up to a secondary drive that said certain files were not valid or that the file was not readable. When I plugged it into my Win7 PC, I got the standard "Scan & Fix Pop Up" that pops up with almost every other USB drive I plug in. Since I was getting the "invalid file" error during back-up, I thought I would try the Scan & Fix option to see if it would repair it. After the scan completed, it told me that it found a few errors and that they were fixed. I immediately tried to access my drive and that's when it started to give me the error listed in the title.
I can no longer see any files on the drive. The drive is listed as Local Disk (N:) in My Computer (same drive letter it had listed before). It listed properly in the the USB Removal task panel with the correct drive name. It is also listed properly under Disk drives in Device Manager. When I run the Disk Management tool in Win7 to view partition information, the disk is listed as RAW File system. There are no strange noises. No clicking, no whizzing, or anything. I just cannot access anything on it.
After a lot of searching online, I tried running chkdsk /f which yielded no change and also TestDisk from cgsecurity.org. After a QuickScan and a DeeperScan, TestDisk was able to find (2) FAT32 partitions, but it said that both were not recoverable. I'm in the middle of running PhotoRec, but so far the results are yielding broken files and non-readable images.
I'm starting to have trouble finding out how to go about recovering the data from here. I've read in places that I may have to fix the MBR on the disk using fdisk (which I thought only applied to connected system disks). I've also heard of tools such as EaseUS Partition Recovery and MiniTool Partition Wizard, but have not tried those yet. As I said, it is absolutely critical that I retrieve data from this drive because while I was able to backup the majority of the drive before this started happening, there is 1 wedding on there that was not backed up. This is a once in a lifetime event that needs to be retrieved otherwise I have nothing to give the client. Any help on how else to proceed would be sincerely appreciated.
Thanks!
