My external hard drive became inaccessible, parameter is incorrect. In My Computer, it shows the disk as a "Local Drive" and it cannot be accessed. In Disk Management, it shows the drive is healthy, but has converted to a RAW drive somehow. I tried to change the letter of the drive, but that didn't help. I used a program called TestDisk and it shows that the files are on it and can be copied to my computer. I have researched the subject, but cannot find a solution. Is there a way to make the hard drive become accessible back to the NTFS format and keep the files on it without having to re-format the drive? I don't have the ability to copy the entire contents onto another hard drive, so I am hoping there is a way to fix this without having to completely start from scratch.
Not that I know of..… I think you are screwed on this..... Sorry. Sound like to me the partition table is gone and as far as I know there is no way to recover from that.
That's what I have gathered, but I just wanted to make sure before I pulled the trigger and deleted everything. There are a lot of programs out there that hint at a solution, but I wasn't totally sure. Thanks a lot!
I had this same issue about a month ago on a new HD that was only 2 weeks old. First and only time in many years and about 20 HD's that this has happened on. I am using this HD for "back up" of files that are on other HD's. Hopefully, two hard drives won't fail at the same time...so it is still "effective" as part of my system "but" I have read a comment that the data changinf from ntsf to raw could indicate the drive is failing. I haven't been able to confirm that. the other comment I read too often is that it could be a virus==but all the other HD's are just fine. Lots of FUD on this issue.
How does a drive revert to RAW data? What causes it when its not a virus...or..what exactly is the "failure" that causes the change? I used a data recovery program that could only find data that had been written to the drive in the first 4-5 days. The data that was written in the most recent 3-4 days was not found. The first data found was totally scrambled and unusable...which should not have happened as all the files were "first writes" and should have all been linear and continguous...but I have no basis to make this assumption.
