How to fix bad sectors on USB HDD?

Question

Hard disks

WD My Passport BZZZ5000ABK is available.
It is divided into two logical partitions. Recently, when connecting, the second section began to appear somehow not stably. Sometimes it doesn't show up.
I looked at SMART in CrystalDiskInfo and it turned out that the values ​​​​of C5 and C6 (197 and 198, respectively) ticked the counter to "1".
I uncovered Victoria, but she does not see the disk point-blank.
Same with MHDD.
Shamanil with IDE and AHCI modes. Try as I might, everything is empty.
I thought to remove the disk from the box and connect it directly to the SATA port. However, having opened the box, I realized that the USB-SATA controller is corny built into the disk and cannot be dismantled. Naturally, there are no SATA ports there either. That is, you can only work normally, via a USB cable.
What should I do in such a situation? Do not backup all 500 GB in order to completely format the disk and fill it all over with a new one?

Answer 1

Does it look like this ?

Answer 2

Strange approach! The disk is dying, but you do not want to backup its contents? So you don't need it much, at least not all 500 GB.
And you need to do exactly as you wrote at the end - merge the necessary information, reformat, upload something that is not valuable or has a copy. Keep track of the number of these unstable sectors. If it grows further - the disk is scrapped, it died like that. And some magical methods of treatment - fairy tales all this.

Answer 3

Just like resurrecting the dead, you need to sprinkle living water)))
