Clone the hard drive with bad sectors

Hi all,

I need your advice, I am thinking about clone my hard drive with bad sectors to put them on another hard drive as I guess the old hard drive is on the way out sooner or later.

Do you think is it good idea to clone the hard drive with bad sectors and put them on another hard drive so I could recover my files without send the hard drive to the professional??

Would it make it worse if I attempt to do this?

We need more information
Is this the Windows OS drive? or is it just a Data Drive without an OS on it?

When you clone a disk, it is a mirror copy of the source drive with the bad sectors and corrupted data on those sectors. So, the problems with the drive will be imported onto a new disk.
It is easier and cleaner if you just copy and paste your files to a new drive. If you are having problems accessing the drive you can make an Image of the disk with a 3rd party Imaging/Cloning app. You then can browse the Image and copy your files from it to another drive. And you will no longer need the failing drive. If you keep working with the failing drive, it will fail sooner and may fail before you get all the files off of it.

No, it is not Windows OS Drive. It is just Data drive without the OS on it. I am thinking about to clone the old HDD hard drive to put them on SSD hard drive, so I can attempt to recover my data using with the data recovery program.

When I clone a disk, can I create a ISO image of the disk to put them on a new hard drive?

Do you think it is a good idea to do this to clone a disk to back up my data and attempt to recover my files or do you think if I should send the faulty disk to a professional data recovery company who will do this more easily?

I am hoping that it would not affect the disk and would not make it worse if I attempt to clone a disk. I don't have any problem with accessing the drive, but I am having a problem with accessing my files through on the data recovery program as I have lost my files due to crashes from the OS.

I hope it will give you an idea with what I am trying to do to save my money without send the drive to a professional data recovery company.

As I mentioned, it is a bad idea to clone your failing disk. Be aware that if a drive is failing with a lot of bad sectors, most Imaging/Cloning apps will fail to clone or image because of the health of the source drive.
As I stated, you can make an Image file of the disk and save it to a different drive. This is almost the same as a Clone, except the Image doesn't take up the whole disk. You can store more then one Image on a backup disk if it has enough capacity. Where as a Clone would take up the whole disk. An Image is also similar to an ISO image, if you want to restore it, you would use the Imaging/Clone app Restore feature. Or you can browse the Image and copy files from it.

But as I also stated, If you are successful in Imaging or cloning a disk, when you restore it, you import all the problems the old Disk had to the new disk. All data on the Bad Sectors will be corrupted.

That's why I also suggested you just copy the disk files you want to another disk.

Sending your disk to a Data Recovery center is only a last resort and only if you can't access it and use data recovery software on your own because they are very, very expensive.

In your position I would make a copy of all accessible files on your disk to another disk in a folder named, for example, Backup_1
I would then run a program called HDAT2,

HDAT2/CBL Hard Disk Repair Utility

Which used to be free but have no idea if it still is, on the old disk to see if those bad sectored might be recoverable. Depending upon the state of the damage, some may be recoverable, others not.
Now run a second copy of all your files to another disk, saving in a folder called Backup_2

If you have access to a folder comparison software like Norton Commander, Volkovs Commander, Beyond Compare or even Winmerge, you will be able to see the differences between the file backups. I have a very old version of Beyond Compare which will do a binary comparison of folders and files highlighting differences which will allow you to open those files and see what those differences are.
Winmerge is open source and I haven't used it, but looks at first glance as though it might be similar.

When you have recovered as many files as you can, ensuring all complete files are in the Backup_1 folder, you can delete the other.

I agree... what's the point in cloning a data disk.. it only contains data... I have a data disk which was originally 1 tb and not enough room, so added a 2 tb disk, copied all data from the original, then removed the original. Added to this, this disk had stand alone installed software which runs from links, and these also worked fine after the transfer.
The only thing I would reccommend when doing this is to ensure your drive letter remains the same, and if not, then change using the Disk Manager or whatever other method you are used to using.

If you want to pursue a DIY approach, the best tool for the job is HDDSuperClone (now open source). It understands how to work with bad heads/media. It will clone the easy sectors on the first pass, and then try the more difficult ones on subsequent passes. It's a Linux tool, but the author has produced a Live CD with a GUI.

Windows based cloning tools are unsuitable because Windows interferes with the data recovery process. Most of these tools will keep thrashing a bad sector, thereby accelerating the total failure of the drive. HDDSuperClone attempts to identify a problematic head and will avoid it until the final pass.
