hello guys this external seagate 2tb i have had always 100% health and performance(monitoring with hdd sentinel)

yesterday i turned it on to find out it has 48 bad sectors and only 37% health.

all sectors of hard disk are 3.907.029.168 and with a scan with sentinel it found the bad sector in here 5.985.952.96

so i used hdd regenerator to remap the bad sectors,weird thing is that it took more time than usual cause regenerator was saying drive is not ready......

i tried 4 times and finally remapped the sectors and reached health 99%.

 

i know you ll tell me to replace the disk and i ll do,

but cause its full of media and the bad sectors were only in one specific area.....i dont want to believe that disk is failing......

but why all those bad sectors in one area.....dust?lost magnetic power?hardware failure?just bad sectors....?

i really guys want your help to find out what is happening to the drive and make it last as long as it can,

should i backup the data and make a low level format(to write zeros)will this help?

 

sorry for all the speech i ll be waiting for your help

Your last set of attributes looks good. You can run Seatools for Windows short and long generic tests to confirm the drives health. I would keep an eye on Reallocated Sector Count and Pending Sector Count.

If not yesterday, today, right now, for sure:

coldboot or restart into anything similar to Macrium Reflect [or Acronis True Image if you're a geek], make one if not two folder/file backups and/or one if not two full-image backups of the data partition and of the OS partition -- onto at least one if not two usb external hard-drives.  After making the backups, do a separate verify of the images made.

all i want to see is why today the pefrormance of the internal disk is getting lower......

Paul, you're right as rain!  Do you have another, 2nd, external HD for your backups?  I found out the hard way once that it's not always a good idea to have only one ext HD for backups.  The one ext HD with my really needed backups - was kaput software-wise.  Now, I have more than one.

In the future I wouldn't choose Seagate drives. Especially in an external enclosure their failure rates are terrible.
