I need Help in fixing a drive with bad sectors. A little info for best assessing my question:
I have been given these steps from an expert in another question to prepare and format a drive (high-level formatting) and I was recommended by a colleague to prior the high-level format, to do a low-level format first (to manage the bad sectors).
The disk in question is a Windows 10 Pro hard drive 1 TB (I have unsuccessfully reinstall Windows with keeping files). I have extracted the drive from the computer and placed in an enclosure making USB accessible.High-Level Format:
I have been given these steps from an expert in another question to prepare and format a drive:
Tasks I did prior placing the question:
- Boot windows installation from USB drive
- Press Shift+F10
- In console type diskpart.exe and press enter. In this program execute following:
- select disk=0. Disk 0 is your destination drive, so be careful, all information on this drive will be removed.
- create partition primary
- select partition=1
- format fs=ntfs quick
- exit, now you have bootable drive C
I have run chkdsk and downloaded/run other sectors checking apps follows with result at its side:
App Windows Chkdsk:
Results: Read error with status 0xc000009c at offset 0xc78ba000 for 0x400 bytes - Unable to read file record segment 1E2E8” – also doesn’t say if the bad sectors marked as bad.
App Paragon Partition Manager,
Ran the checking file system
Results: ‘/O error on hard disk’, so it seems that this apps does not fix bad sectors.
App EaseUs Partition Manster,
Ran scan surface, gave sectors errors, but found out it does not fix it
Results: doesn’t fix bas sectors
App MiniTool Surface Scan.
Ran scan surface
Result: said “Surface Scan complete no errors found”
Ran scan surface
Results: found errors, and I cliecked ‘Repeair’ and is now fixing sectors (I am running at this moment)In summary, my questions are:
- For high-level formatting, diskpart.exe is ok?
- What is EE opinion on low-level format prior High-level format?
- Is MHDD reliable for this tasks? – (EaseUS page sent me to MHDD for fixing)
- Does chkdsk process marks bad sectors as bad as to not to be used?
- Should an apps be reliable (in this case MiniTool) if say no errors when all others say that there was errors?
- DiskGenius, I have it runing repairing sectors, what is EE opinion on this apps?
(I tried as explicit with my situation as possible - please advice, that I am considering to purchase a new drive but want to see up-to where I can fix this one)
