    OK,, so it seems to be an intermittent problem throwing us into tantrums. You may have to run TestDisk many times. I do not know how with this intermittent problem you are going to manage.

    Click on [List] . Do you see your files?
    If you do not see your files but get an error message take a screenshot and post it.

    Note:
    1. If you see your files you need to copy the files to another external disk plugged in. For that you must have plugged in the external disk before starting TestDisk..If you do not have an external disk now, you have to get one and run TestDisk again. TestDisk should see the external disk along with your system drive (500GB) and your 2TB disk.
    Read here: Copying files listed by TestDisk during Recovery My external hard drive suddenly became unllocated: - Page 3 - Windows 7 Forums

    2. If you are closing TestDisk now: : Since now Bootsector is OK and Backup boot sector is OK when you reboot the computer, your 2TB Disk should be accessible and you should be able to see and access all data in it. - if that was the only problem.

    3. If you get an error message when you click on [List] and do not see your files you have to click on [Repair MFT] and proceed

    If TestDisk returns the message that MFT and MFT mirror is OK then as stated earlier you should run checkdisk

    If Test disk returns an error message that MFT cannot be repaired. then you need to try the trial version of the commercial software GetDataback or active@file recovery and check whether you can see your data.

    You now have all th data on using TestDisk that should help.

    Let us know how it goes.

    After the surgery on 01 Mar and 04 Mar I will be off my PC for atleast 20 days till my eyes recover fully..

    I still don't see my files and folders , so I can't copy out my data yet.

    - - - Updated - - -

    just to recap . I am running ORG.BS again since that was the result:

    Boot sector - OK
    Backup boot sector - Bad
    Execute [ORG. BS] command.
    and I reached the next screenshot , I entered Y and pressed enter.

    - - - Updated - - -

    but it seemed to have hung there and nothing happened so far.

    - - - Updated - - -

    it came back to the next screen so I pressed boot. and now finally I see both status as OK. I will proceed now to "repair MFT".

    - - - Updated - - -

    Good news! I now see MFT and MFT is ok. This looks like progress, I will now proceed to run CHKDSK.

    - - - Updated - - -

    Now running CHKDSK. Its moving very slowly. ETA keep increasing to a huge number . hopefully doesn't take too many overnights.

    - - - Updated - - -

    just an update. this doesn't look good . anyway here is a screenshot. will post another screenshot sometime tomorrow if there is something different.

    @KCC

    After looking back and going through all that has happened this is the final verdict - postmortem

    There was a catastrophic failure - sudden death - of your disk. As a matter of fact that resulted in your system calling for a checkdisk.

    Checkdisk is only trying to do a cleanup operation, but the cleanup is not going to bring the disk alive permanently. (It may bring it alive momentarily when clean. But since the generation of bad sectors is now a continuous process it will die again in no time - my analysis.)

    The fact that [List] files shows only two root directories that were created on 18 Feb 2023 08:56 and no folders and files in it means there is no data present.

    We have only been beating a dead/already dying snake for the last one week ..

    When you replace the disk with the SSD , you will also need an external disk for backup. Buy a branded enclosure and a disk to put in..( I use Orico enclosures. I also have a two bay Orico dock hosting my 5TB backup disk. Back up with Macrium Reflect.)

    When you buy the enclosure, put this 2TB HDD in it and try

    Note: Even SSDs can fail. If it is a hardware fault (memory cell failure) there is every chance of such a failure completely wiping out all data. So backing up is all the more important. If it is only a file system corruption ( logical fault), conventional data recovery procedures can be applied to recover the data or restore the disk (Partition recovery).) .

    Hi jumanji

    Thank you again for your comprehensive analysis. After more than 16 hours the chkdsk only progressed 40% with a long list of "file record segment xxxx is unreadable" errors. I will terminate the chkdsk then since the HDD looks very dead.

    Thanks also for the tools you mentioned esp the Macrium software and docking station.

    I have already a 5TB external backup drive, I just didn't backup the last few weeks of data. This is the first time I've experienced catastrophic HDD failure and with no warning. oh well, lesson learnt. I should backup everyday now or whenever there is important new data.

    - - - Updated - - -

    oh I think you mean this enclosures ORICO 2.5 inch USB3.0 Hard Drive Enclosure
    I can also plug in HDD into the Orico enclosures from my old laptops , for less important stuff. I will use it to test that faulty 2TB HDD first although I don't have much hope I will see anything.

    KCC,

    To counter my own tendency to forget to make regular backups, I have an SD card in my otherwise rarely-used SD card slot so I run a RoboCopy script to back up as much as I can every hour.
    When I started I could only backup a few key files [MSOffice Outlook's pst file, my finance spreadsheet] because the SD card was small but now that I've got a much larger one I can backup the whole of my Documents folder & much of my audio collection.
    Such local backups are exposed to malware so are always at risk. They do not replace proper backups to external drives that are then removed & locked up in Fort Knox. But they can be a life-saver when an internal disk fails.

    When my internal disk failed several years ago, I was able to rescue new Desktop & Favourites entries but nothing from any other folders***. I lost about three hours work. I counted myself very lucky.
    That prompted some thinking. Now that I've adopted the SD card interim backup solution I never expect to lose more than an hour's work.


    *** In an earlier post, I explained that my disk failure was progressive.
    I could not see any contents when it was fitted internally.
    When I connected it in a USB enclosure, I could see the Desktop & Favourites folders but no others.
    After a period of non-use I could no longer even see those folders.



    Best of luck,
    Denis

    Thanks Denis,

    I think the Macrium software recommended by jumanji can probably do that automatically. WD Discovery which came with my new 5TB backup drive can probably do something similar but just that I didn't explore that yet. Will try both once I get my new SSD next week and after everything is running normally again. Thanks for the idea, I also have Malwarebytes in my laptop, currently using the free edition.

    Hi. No quarrel with anything in this post, except the recommendation for Orico.

    I have had two Orico 2.5" external drive cases fail. USB drive doesn't work. Take out the drive and put it into a different case, same cable, and shazam! the drive works.

    I had an Orico 2 bay docking station fail.

    Did I ever get a useful email reply back from them? You guess. Now I use Anker or Fideco products.

    I had an Orico 3.5" drive external case that was so poorly designed that the HDD wasn't properly supported in the case, putting pressure on the SATA connector.

    @x509,

    I haven't recommended ORICO specifically . I have only said KCC should buy a branded enclosure and HDD to put in. And went on to say "like I have a ORICO enclosure and dock."

    After going through user reviews and what is available in India, and the price factor, I bought these years ago from Amazon India. KCC is free to buy whatever good branded enclosure/dock is available in Canada..

    Incidentally, my ORICO enclosures and the dock are performing satisfactorily to this day. I have no complaints.( Note: These are previous generation ORICO products not available today. Now I see ORICO has upgraded most of their enclosures/docks. May be these upgraded products are not upto the mark)

    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.
    Thanks. My wife ( a doctor-Psychiatrist) had these years ago, in the same superspeciality eye hospital , first in one eye and a year or two later the second eye. Since then we have been fighting , With clear vision, she couldn't stand a bright light but with impaired vision I needed bright light. Now it will cease. Both my eyes will be fixed Right eye - 01 Mar and left eye - 04 Mar.( both of us are covered by Central Government Health Scheme - by virtue of my positions held in Central Government) and the hospital bills including the cost of the IntraOcular Lense will be raised on and paid by the government ).

    I was also told that I will need glasses for near-vision after the surgery but my wife is doing well without any near vision glasses.

    Thanks jumanji and x509,

    appreciate all your recommendations, up until this thread discussion, I've never heard of of orico, anker or fideco. Up till today I'm still waiting for the new SSD and tools. There is a shop near me that sells orico products but I'll check out the others also if they have them. I'll go get an enclosure ( relatively cheaper than the SSD and tools) once I get my tools. I'm always happy to hear feedback on how products work well (or not).


    on a separate note, my PC is slow now, but I'm assuming its my PC being manic depressive due to my faulty and a "ghost" of the D: which sometimes show up and sometimes doesn't. it takes 4mins to boot up instead of less and 1min and I have really watch and quickly press any key to "skip disk checking." It takes about the same time (sometimes a bit longer) to shut down it will say "Shutting down..." and after 4mins it finally does to my relief. I even ran my antivirus and malware checks and nothing was found which is good. Is this situation of manic depressive "slowness" due to my D: ?

    If so, then I can put my mind to rest everything should work fine after I plug in my new SSD. Thanks again.
