I get the "You need to format the disk in drive I: before you can use it." message when I try to retrieve files from my storage device. When I say "no" to reformatting, I get the "I:\ is not accessible. Data error (cyclic redundancy check). I have read thru at least 3 dozen posts on this forum and can't wrap my head around which step to take first and last. I did do some things and have determined thru device management that the data is that, it is in RAW. Would someone be willing to walk me thru the process step by step to recover my data. I really need it because my back up crashed a while ago and I failed to make another. <_< I would be much appreciative for the help.

Thanks... Bobby

Hi Bobby

Did anything happen to the drive before this? Did the problem suddenly appear while in the middle of using it or when you rebooted or connected it to the computer?

Okay, in that case, let's take a quick look with TestDisk and see if it is a simple problem. If not then we'll check the disk's health and go on from there.

Download TestDisk from
http://www.cgsecurity.org/testdisk-6.13.win.zip
and extract it to your desktop.
Open the folder testdisk-6.13
Double click testdisk_win.exe to run it.

TestDisk is a console application so you have to use your keyboard to interact with it instead of your mouse.

Choose Create and hit enter (this makes the file testdisk.log that is automatically created in the folder testdisk-6.13)
You should now see a list of drives including your external drive.
If you have any difficulty identifying which one it is, let us know what you see and we'll help you figure it out.
Select the external drive and choose Proceed and hit enter
It should automatically have Intel or EFI GPT selected (if not, select Intel and let me know) hit enter
Select Analyse and hit enter
Select Quick Search and hit enter
Say 'Y' if it asks if the disk was made in Vista/Win7 (even if it was made in XP say 'yes')

If you see what looks like a normal partition, highlight it and press
p
and see if you can see your files and folders there. Press
q
a bunch of times to back out of TestDisk.

Let me know how it went. If there were problems or you did not see your files and folders, please copy and paste the contents of the file testdisk.log which you will find in the testdisk-6.13 folder.

James

Followed the instructions explicitly twice. Got an error that said "unaccessable". I have a couple of screen shots so that you could see what I'm seeing, but I can't fiqure out how to add them to this message. Thanks... Bobby

Here are some instructions for using PhotoBucket to post images. Let me know if you have difficulty with it.
http://www.bleepingcomputer.com/forums/topic14738.html

Also, I have had people post pics to their Twitter. If you can do that and let me know where it is, I'll host it and put it in this thread.

At what point in the process did it say "unaccessable"?

James

I got the "unaccessable" at the end after I had followed all the step. I will upload to photo bucket as soon as I can. Once again, Thanks!

Hi
Yep, that works :)

In the second picture, where it shows the partition highlighted green, is that where you pressed p and were told that it was "unaccessable"?

Can you post the contents of the testdisk.log file which should be in the same directory as the testdisk program?

Yes, that is where I got the unacessable. I could not find a log file. I don't think one was made for some reason?

Okay, lets check the boot sector.

Run TestDisk again
Choose Create and hit enter (this makes the file testdisk.log that is automatically created in the folder testdisk-6.13)
You should now see a list of drives including your external drive.
If you have any difficulty identifying which one it is, let us know what you see and we'll help you figure it out.
Select the external drive and choose Proceed and hit enter
It should automatically have Intel selected (if not, select Intel and let me know) hit enter

This time Select Advanced and hit enter

Select Boot and hit enter

Take a picture of this screen and post it.

Press
q
a bunch of times to back out of TestDisk.

The logfile may be simply called testdisk in the testdisk folder if your OS is set to hide known extensions. See if you see anything in there called testdisk that has a textfile type icon next to it. It may be listed between readme and testdisk_win. That might be the logfile that I need to see.

Yep, that's the log I need. Sorry I wasn't more clear on where it was at first.

I see
NTFS: Can't read MFT

That is a tricky one. I'll look into that more and get back to you.
