HDD bad sectors when file transfering.

[GEOrifle]

Hi. Recently bought Seagate External HDD Databackup 6TB. It wasn't bad for 10 days, no bad sectors and nothing suspicious. Then i was transferring an ISO image from it and 180 bad sectors appeared, file wasn't transferred also. So every time i was trying to transfer same ISO file additional bad sectors were appearing, another files and ISO's had no problems. Finally "COLLECTED" around 1000 bad sectors and 3 day Life left on it. Returned to store.
So question is what went wrong? Where i made mistake?
Now i bought for storage data Toshiba NAS drive, tech told me it work with no problems and was cheaper than regular Desktop one.Any different opinion on it?
Which one is better use it in case or like external enclosure?
Thanks.

Where i made mistake?

Buying a Seagate SMR drive.

A Toshiba NAS drive doesn't sound too bad. Is that just the drive, or is it in a NAS unit itself? (Do you connect it with USB3.0 or ethernet?)

It's just bare drive, going to put into the PC case or external for DATA.
Seagate's are that kind BAD?
LOL, i have 2 Toshiba's drives 3 year and 5 year old and still remaining 100% health and 100% Performance. Hope i didn't make another mistake at this time

Yeah... can't say I am happy with Seagate's quality these days.
Bad sectors happen once the R/W head goes over the platter to that area, so, you wouldn't actually know they are bad until it passes that area.

That is why you need to "burn in" any new HD for a few hours / days (depending on the size) to get the "kinks" outs. They usually fail in the beginning, or the end of it's life, or a typical bathtub curve.

How to do "burn in" ?

You install a SMART monitor (like crystaldiskinfo), then you basically write to 100% of the drive.
I am currently using https://github.com/Microsoft/diskspd and it is pretty good.

This is good advice. Always do at least one full drive write before committing anything important. Preferably a full surface scan too. Drives can, and do, get damaged in transit. Nothing you can do about it.

But then again, you really shouldn't trust just one drive for backup duties...
