So, I received this HDD today, and I decided to test it on HDAT2 to know if I would have to deal with premature failures. Instead, I accidentally created one while using the "Create Bad Sectors" function on the first gigabyte of the hard drive. It made S.M.A.R.T register thousands of Current Pending, Uncorrectable and Reallocated Sectors, while hanging on HDAT2 read or write tests, failing all SeaTools for DOS tests and going invisible on Windows.

Using Victoria, I was able to clean Current Pending and Uncorrectable Sectors and the drive doesn't hang anymore, but I still have 288 perfectly good sectors that were reallocated.

Is there any way to have them back, like a self-test that checks for the health of bad sectors? If that's impossible, is it recommendable to RMA the drive to Seagate?
