I'm using testdisk7.1WIP 32 now.

In test disk i only see 2 disks, the internal ones, and the external as a drive only, see picture:

the logfile is at 50mb, by just starting quickscan and aborting directly, is that normal? after running for a day it's well over 300gb. it reads:

("felaktig funktion" means erroneous/bad function).

When a disk appears as RAW means that you have a partition in your partition table.
Running TestDisk on a "Drive" will display the whole available disk space as Unknown.
Using the menu Type you could add a file system.
But ist doesn't help as much because a drive has no partition table and a partition starts at the boot sector.
When the start and size of a partition doesn't match, you won't get a reliable result.
RAW means that you have a partition, but either your boot sector is BAD, your partition is not formatted or the file system is faulty or not recognized.
That's why selecting your disk and confirming at Analyse will display your current partition structure (partition table).
When your correct partition is still in your partition table, it'd be possible to run a boot sector diagnose.
It wouldn't stress your disk as much.
On a Drive with partition table type None it's not possible.
Please copy and paste the content of your testdisk.log into your next post.
At the first you'd only need to confirm at Analyse and I'd like to watch only your current partition structure (partition table).

Re: Lost the partition/mft/boot sectors

#15 Post by monkey » 10 Jan 2016, 07:59

I have a very similar situation. My disk shows up under Disk Management as RAW. When I run TestDisk (v7.0) it only shows up as a Drive, not a Disk. When I choose the Drive, the default partition is None. I've tried choosing all of the different partition types, but it always says that no partition is found. Attached is the log file from when I tried a Quick Search (it has a lot of the read err lines that the previous poster also saw). Note that I have two USB hard drives attached. The one I'm trying to recover is the 320 GB drive. Also, I previously let the Quick Search go to completion and it created a 177 GB log file with many, many of the same read error messages (unfortunately I wrote over that log file). Also, I think I accidentally pressed enter too many times. I did not mean to execute write_mbr_i386.

Any suggestions would be very much appreciated!

The log file was too large. Excerpt is below:

Can you try TestDisk 7.1-WIP ?
If the problem is Windows related, it's better to also try under Linux.

Thank you for the response. I tried TestDisk 7.1-WIP and got the same results. Does the error that it keeps repeating give any clue about what the problem might be with the drive?

Anyone have a response to my inquiry about the error message I'm seeing:

file_win32_pread(580,1,buffer,19(19/0/1)) read err: read after end of file

My log file repeats this message over and over (~300 GB worth). Does this indicate any specific problem or how I might proceed?

This error message can be caused by
- a Windows problem, it's why I recommanded you to try under Linux. There are various Linux LiveCD/USB solution...
- a hardware problem. In this case, you need to contact a data recovery company.
As Fiona has already explained, it's better to use the PhysicalDrive (/dev/sda, /dev/sdb...) than the drive letter.

Thank you again for your response. I thought I had tried previously on Linux, but it was a different tool. Also, I saw Fiona's suggestion to use the drive, rather than Disk letter, but when I ran TestDisk in windows, it didn't show up as a physical drive.

I just now tried TestDisk 7.1-WIP under Linux. It recognized the disk as a physical drive (/dev/sda), but it was still unable to find a partition. I tried a Quick Search and also a Deeper Search, but it did not find a partition. It produced a large log file (~400 MB) that had a lot of errors like the following:
file_pread(4,11,buffer,625141885(38913/72/5)) read err: Input/output error
