If I have an HDD with some bad sectors and I format the disk (from Windows) or re-partition the disk, will bad sectors still be marked as bad?

The first 7GB of a 500GB NTFS partiton was accidentally overwritten with another file. Is it possible to recover some of the data in the remaining 493 GB of the NTFS volume? The partition table is intact. The executed command was:  dd if=file of=/dev/sdc1   Thanks  Edit: My question is different. I overwrite first 7GB of NTFS partition. Other question mostly deals with hardware failures or bad sectors.

I am planning on selling my laptop. So I formatted my disk using the Disk Utility and chose to overwrite the disk with zeroes.  Two questions:  Is this the same as overwriting the disk using dd?  sudo dd if=/dev/zero of=/dev/sda   And is this method secure enough so that buyers can't easily recover the previous data? Or should I take additional measures (like encrypting the disk, destroying the headers, etc.)?

I ran chkdsk /r on drive with some bad sectors, and I manually aborted chkdsk at stage 4. I took this screenshot just before exiting chkdsk.    1 ~ 3 stages are passed with no error messages and stage 4 only showed "looking for bad clusters in user file data..." nothing more, I aborted chkdsk at this point as shown in the screenshot.  So, at stage 4, since no messages were recorded on prompt yet, that means stage 4 didn't do anything to data (clusters) yet.  Am I correct?

I apologize if this question has been answered previously.  I've checked through the "similar titles" but haven't exactly had any luck.  I'm aware of the problem and I know the solution, I simply don't know how to implement the solution properly.  Any help would be greatly appreciated.  What I'm experiencing is a SMART failure 05 and I'm being warned that a disk failure is imminent.  My old partitions is what is causing the problem and the solution is to skip over the bad sectors via a new partition.  I have a 100gb hard drive, and I think it's safe to say that the first 20gb are borked in this regard.  How do I set up a partition outside of these first 20gb?  Would I designate this as "free space"?  Or something else?  Please be detailed (e.g. screen shots), I'm fairly computer literate but I'm a beginner when it comes to Ubuntu 12.04.  Thank you for your help!

I've searched through several questions but didn't quite find anyone treating mine.  So, I have a 1TB external hard drive I use for backup purposes with only 1 NTFS partition. Today using DiskPart I formated that partition by mistake (who would have thought the disc count started in 0 and not in 1). The complete command I used was:  format recommended override quick label=Windows   So I performed a quick format, and from which I've read after a quick format it's possible to recover the data stored there. Anyway, as soon as I realized it wasn't the partition I wanted to format the one I specified I removed the access to my external drive to minimize possible damages.  Now, the MFT is the metadata part where the file name, creation date, access permissions and contents are registered; and it's mirrored too (so there's a copy of it somewhere in the disk). What I don't know is if a quick format erases that MFT mirror too, I hope not.  I'm running a program to recover files on it but I'll have to save the files to another location (once it's finished scanning, ~12 hours from now) and I don't quite have over 900GB of free storage where to put the data.  I would like to know if there's a program or procedure by which I could restore the old MFT in-place and have all the data that used to be in there accessible once again.  Any help or light you could shed on how to proceed or what programs to use is really appreciated.

I have a dual boot of Windows 10 and Ubuntu 16.04. Recently I upgraded it to 18.04. As soon as I did it, it started showing DISK IS LIKELY TO FAIL SOON (37° C / 99° F).    I checked the status of my disk via Windows and it shows it’s perfectly healthy. I assumed the error occurred because my partition size of Ubuntu was 64GB (which I now increased to 86GB). Please help me out with this.    Edit: The results of smartctl - attributes

A few days ago I was in a middle of copying or cutting folders and data to my external hard drive and it was corrupted.  I have tried to locate the lost information on Test Disk but I have now lost it because it has already been over written. The file is 0. 0. copy and completed.  I have now only have the image.dd file. How can I restore this to it's normal folders and files without losing the names? Many thanks.

Is there a way to read ext4 partitions from Windows? If so, what can I do?

My wife's Windows 7 (64-bit) box has suddenly developed a SMART "disk is bad" status.  I'm attempting to copy everything off (no admonishments about lacking a backup regimen, please, I know already  :(  ) by creating a System Image across the network to a different machine, but it gets to a certain point and starts taking forever.  Doing a chkdsk reveals that certain files cause this by having many bad blocks (like dozens of thousands in a row, if the event log is any indication) and causing the system to do its standard try-to-recover-and-relocate-upon-access thing.  But this is taking so long, I'm afraid the disk will fail completely before I can get the damned thing copied.  However, several of the files so far have been ones that she has copies of elsewhere, so I am able to just delete them prior to retrying the backup to speed things up considerably.  So:  is there some tool or procedure that will try reading each file, and upon hitting a bad block, just tell me about it and skip to the next file?  So I can see which ones I can just dump and which I need to let it try to recover?

I just bought a new external hard drive (). In a PC with Windows 7, I formatted it by Right-clicking the drive > Format (Quick Format - NTFS) before using it and, and then checked out its Properties.     I noticed that it already has 118 MiB of its disk space already used, despite being newly formatted and no files transferred to it.   Questions: Is the disk space occupied by the disk overhead, metadata, etc. correlated to the total disk space capacity of an NTFS-formatted hard drive? If yes, how is it computed? (How much disk space will be 'used' by default on a brand new, newly formatted hard drive, given its disk space capacity and if it is formatted to use NTFS?)

As we know, in Windows the partition location is prefixed with [a-z]:. What happens if there are more than 26 partitions?

I have one hard drive. It's partitioned into 4 partitions, one of them is encrypted by Windows 7 Bitlocker, then I used Acronis Disk Director to merge both partitions during the process PC power off now the encrypted partition and when I try to enter the partition I have a message to format it, the other partition seems to contain 20 MB but when I open it I found nothing.  all data in this partition is so important to me , so please if anyone can help me recover my data I will be thankful

Got a problem with my laptop manufacturer's partition. It's FAT32-formatted and fails under same curcumstances as for topic starter at . It seems like vfat got a problem working with x-gvfs-show parameter. Also, I seek for more "painless" solution then "format-and-refill", because this one is created by the manufacturer and (as far as I know) got specific structure adapted for BIOS.

I dont know whether I can ask this question here or not. Please consider this if it not a proper place.  Here is my problem, I was using Windows XP previously and I changed it with Windows 8. After installation of Windows 8 when I booted it up, I found my HDD behavior changed. Sometimes it is running and sometimes it is not.  My system specification is :  Intel Motherboard (945 Express Chipset) Processor (Core 2 duo) RAM (2 GB) HDD(500 GB)   When I open my HDD for getting the cause of problem (I open that casing and check head  and disk). I did not find any hardware visible problem. Just it is stop rotating, before it can boot OS.  Can someone help me to fix this problem or recover data in this case.  NOTE : Warranty period expired, and I have my 5 projects in that and some important documents.

Q1: Can forcibly powering off a PC without using the built-in shutdown/reboot functions, cause a HDD to accumulate bad sectors? Whether it be the result of BSODs, lockups, crashes, etc.   Q2: If so, are these bad sectors repairable? I know an OS typically relocate bad sectors to other areas of the drive, but once a drive accumulates too many it just dies.   I have read up and saw things about 'soft' and 'hard' bad sectors. One caused by software and the other being actual physical damage. The reason I am asking this is because I have had several HDDs die on me in the past year, far before their estimated lifespan, and one thing they all had in common was that I had forcibly powered off my PC a lot.

My Portable harddisk was working fine. I once accessed it from a linux terminal. Later when I tried to use it in window it said You need to format it before you can access  In Ubuntu also when I plug it, it does not appear.  I tried running chkdisk but Windows says Raw file system could not be processed.  Is there any way I can get back the disk data?  Recovery software does not preserve folder when it recovers data. Also When I tried it it says "1 days remaining to process" nearly 350GB data.
