Currently I said him run chkdsk /f /r J:

After completing any steps in the other TF room plan to run chkdsk /r /v J: using Windows RE.

This do as

1. Boot from installation media
2. Go CLI admin CMD
3. run chkdsk /r /v J:

by this may corrupted data or other problems of hdd get fixed...?

in other words like someone said previously in this thread page 2 ...:>>>> ????

Find a flash drive that you can format (> or = 8 GB)

Create a bootable Windows 10 iso:


https://www.microsoft.com/en-us/soft...load/windows10
Download Windows 10 ISO File
Create Bootable USB Flash Drive to Install Windows 10


Boot to the windows 10 iso > open the Windows advanced troubleshooting menu on the iso > click command prompt > type these commands (comments are in parenthesis)

bcdedit /enum
bcdedit | find "osdevice"
(note the partition drive letter)
c: dir
d: dir
j: dir

chkdsk /r /v W:
(drive letters may change when using Windows RE)
(change the letter W: to the drive letter that has the folders/files similar to J:)
(reboot as needed)
(running chkdsk in this fashion typically displays ETA)
(plan to run in the evening so that a substantial portion is run overnight)

Hi @lse123,
I am afraid you are clinging on to an old recommendation made by zbook. Forthwith stop using checkdisk on the (logically) faulty external HDD. Checkdisk cannot repair the errors in the uppercase file. Running checkdisk unknowingly has only aggravated the problem. ( When checkdisk is unable to repair a problem it aborts and leaves your HDD in a much worse condition - perhaps ruining all chances of data recovery.)

My recommendation in my post #30 on my entry to this thread and also that of zbook in his post #29 almost arrived at simultaneously after seeing your post #28, was to check your friend's PC for any malware that could cause uppercase case file errors. ( I took a little more time to compose my post and submit by which time zbook had already posted recommending that you "Open a new thread in: https://www.tenforums.com/antivirus-...stem-security/
Ask if a Farbar scan is indicted.
If yes, then perform the scan."
So seek expert guidance on how to cleanse your friend's PC of any malware in the subForum: AntiVirus, Firewalls and System Security and do it first.

( In all cases where the HDD becomes inaccessible and OPs want to recover the data, I never jump to checkdisk as a first step. Only after a short investigation with TestDisk and if Test Disk confirms no MFT corruption, I would advise running checkdisk. If TestDisk says MFT is corrupted then straightaway on to Data Recovery procedure using commercial software. Running checkdisk on a corrupt MFT will abort itself unable to repair and leave your HDD in a much worse condition.In this case Checkdisk found errors in uppercase file which is an MFT corruption and it never ran to completion. Post-mortem of course but I am destined to make)

BTW
The HDD is Seagate Desktop HDD 4TB connected in a USB ext adapter SATA...

would recommend that you try Getdataback pro (Trial version) and check whether it can recover the corrupted files. ( You can open and play the files and check the file integrity. If satisfied only then buy it.)

Neither me nor zbook are experts in System Security aspects. That is why you have been redirected to specialists on the topic in the subforum on how to ensure a thorough cleansing of the system. The system includes all storage devices that you normally connect to the PC.

At the moment, you need not bother about running TestDisk. That stage has already passed. Just concentrate on cleaning your system and then running Getdataback Pro. There is no guarantee that you will be able to recover the already corrupted data made worse further by running checkdisk but you can definitely try your luck.. Any uncorrupted data that you have verified for its integrity can be saved to another HDD after buying the license if you want to. Read all the documentation on how to use getdataback in the website. The program only scans your disks to show the data and does not make any changes. So you can make any number of mistakes till you get a hold on how to use it.

Note: For those who may be interested in knowing how to use TestDisk for determining whether MFT is OK or corrupt these two threads in Seven Forums:
