    hard drive D: is not accessible


    hello,

    I have an ASUS TUF gaming laptop I bought back in 2019. Processor AMD Ryzen7 with 16GB Ram, 64bit. I am using Windows10 Home 21H2 . My harddisk is 2TB and partitioned as C: for 500GB and D: 1.5TB. D: is where all my files, folder and data is.

    2 days ago I saw one of my new folders inaccessible so I ran ccleaner and updated my windows and after that it was fine. After I rebooted my laptop, my Asus laptop went into PC diagnose and started automatic repair. If I remember correctly it was at "Fixing D:\ Stage1: 40600 out of 110000 36% " and ETA went from a few minutes to 8 hours and after overnight next morning to something ridiculous at 118 hours and kept increasing. For e.g. 40600 went up 1 at a time 40600 to 40601, 40602 every 15 to 30secs and so was painfully slow. This went on until last night and 36% only climbed to 40% in 2 days. It seems like repairingThen the power went out. When power was back up my PC complained it wasn't shut down properly but I was able to boot back to Windows and logged in.

    I saw to my horror D: was missing. I checked with Diskpart and it could only see my C: partition. as my D: In Device Manager it was listed as "unknown device" In Disk management I it as "Disk Unknown", Not initialized. When I tried to initialize it it says "incorrect function". I tried to disable it. reenable, update the driver, but didn't help.

    THis morning I powered on my laptop again and seems like I could at least see D: but when I tried to access it I get:

    D:\ is not accessible " the request could not be performed because of an I/O device error"

    In Disk Management I now see it as Disk0 and online. and the partition as D:\ RAW healthy primary partition. My laptop has asked me to format that partition in order to use it. But I cancelled it because I want to back up some recent data.
    It looks like part of my D: has some bad blocks, I am unlucky perhaps , my laptop is only 3years+ old. And perhaps I also need to replace my hard drive soon also ?

    Could someone please advise what I should do now the fix this issue so that so I can access my data?

    For checkdisk to take so long means there are mager faults on the drive and its retrying a lot. Raw means its lost the parition table you can use specific free parition recover software if you get it back you would need to get data off ASAP and replace the drive

    I suggest you do nothing until you have received advice from @jumanji who has helped many people in your position.


    Best of luck,

    Hi @KCC

    My first question: Where are you located? What is your local time? ( My location India Local time 22:54. Almost bedtime. So can't do much right now but don't despair.)

    We will go slow. Due to my impaired vision I am limiting my computer time and looking at the monitor. ( Hmmm...Only this morning I consulted my CGHS eye specialist and she has ordered Laser cataract surgery for both right and left eye and a whole bunch of lab tests in preparation for it. I have to get it all done in the CGHS empanelled hospitals before I depart to USA on 13th April. So I will be running around for the next few days scheduling it. That is going to make it still slower.. Till I get into the operation theater ,I shall try to devote some time every day to help.

    As with any data recovery project, I do not promise anything. I have to analyse your situation and then see what can be done.

    1. To start with please post a screenshot of Windows Disk Management.. Follow the guidelines here How to Post a Screenshot of Disk Management

    2. Download and install the trial version of Hard Disk Sentinel Hard Disk Sentinel Trial version - HDD health and temperature monitoring and post the overview of your disk.

    A sample screenshot.: will post shortly.

    Hello @jumanji,

    I'm in Canada and my local time now is 1pm. thank you so much for your help. Attached below is the screenshot of DiskManagement. I am downloading the harddisk sentinel in the meantime.

    - - - Updated - - -

    I've just installed hard disk sentinel and here are 2 images, the first one is of C: which is working fine. And the next image is D: which is the problem partition. No worries I will wait for your reply tomorrow then.

    OK,good. Somewhere in Canada over Newyork - same time zone as. ET

    Now post a screenshot overview of D: drive in Hard Disk Sentinel.

    Select your D: drive Disk 0 and not Disk1 which is your system drive.

    Sample screenshot :

    hard drive D: is not accessible-26-11-2021-19-26-19.jpg

    No need to be in a hurry. I am going to bed now and will see it my tomorrow morning about 8 t0 10 hours now.

    Disk 0 has a drive letter D: So the partition exists. It is not a partition recovery problem as Samuria suggested in his post #3

    Good luck with your surgery. The good news is that cataract surgery is very routine these days. You may need a new prescription for your glasses.

    OK, Hard Disk Sentinel puts out some obscure message that isn't of any help.

    From what I understand from your first post - the system initiated a checkdisk operation and it got aborted midway due to a power outage. In current Windows Disk Management your Disk 0, the seagate 2TB HDD is visible as healthy but RAW.

    What I am now worried about is "Is the MFT of Disk 0 corrupt?" If the MFT was indeed corrupt checkdisk should not be run. If run, checkdisk will delete all the files that are not properly indexed in the Master File Table (due to MFT corruption).. I would presume the long time it was taking was due to this. I wish I am wrong So we shall go ahead and use TestDisk to find out the MFT status.

    Do you know whether your 2TB D: drive is an MBR disk or a GPT disk? If not, evoke Windows Disk Management View > Top > Disk List. That will show the partition style of your Disks. Post a screenshot.

    Download the stable version 7.1 from Partition Recovery and File Undelete . Extract it to the root of C:

    You will run testdisk_win.exe in the testdidisk-7.1 .folder

    ( Do not use TestDisk on your own till I give you the go ahead signal with step by step instructions)
