External hard drive corrupted, CHKDSK stalls at 76% complete

I am trying to fix a new Toshiba Canvio 3.0 1.5TB drive that has errors. Each time I plug it in, I'm directed to run CHKDSK, but CHKDSK fails to complete with the /f parameter. The process stalls at 76%. If I run CHKDSK without the /f parameter, I get the following result:



Again, if I run CHKDSK /f, the process stalls at 76% and hangs forever. I've left the process to run overnight with no progress.

I've looked for solutions on Toshiba's website, but haven't found a solution. Any help or ideas are appreciated.

By the way, I'm not super tech-savvy, so if you have a technical solution, please give me as many detail as possible. Thank you!

I had a drive with a bad sector that would stall with CHKDSK /f. It was at the very end of the drive. I repaired the drive by formatting with Gparted or Partition Magic, one of the two, don't remember. When complete SMART reported 2 reallocated sectors and 99% health, been running fine ever since.

Hi mmpfs,

Format it with HP USB Disk Storage Format Tool 2.2.3 HP USB Disk Storage Format Tool Free Download

It is a nice tool to have in one's kitty and as easy as A B C to use.

(Right click on the small exe file and run it as administrator. Remove all other USB drives so that you don't make a mistake of choosing the wrong drive - applies to any partitioning/formatting tool. Check that the correct drive is chosen.)

Were you able to run this program without losing data? I ask because I have about 400GB of data backed up to the external drive. I'll have to copy it onto my computer and some other device because I don't have enough space left on my laptop.

Thanks for your advice and help.

Sort of a stupid question, but I assume that when I run the reformat, I'll lose all of my existing data? I'll start copying the 400GB of data from the drive to other devices just in case.

Appreciate your help and directions!

Yes, if you have data to be recovered, then do not format.

I would rather like to see how your problem drive looks in Windows Disk Management. Post a screenshot.

It well destroy any data you have on the disk. Back up as needed then you can do a repair that writes to each sector. This well force it to reallocate any bad sectors it finds. After you repair this hhd run SMART and you well see how many sectors were bad and reallocated. 2 or 3 sectors reallocated is not unusual, any more than that is a intication the hhd is dieing and should not be used for mission critical data.

Jumanji; Here is a screen shot of Windows Disk Manager:



Disk 1 shows "Healthy". Any other thoughts before I start to save my data to other devices? Thanks.
