IMHO it depends on what caused the bad sectors. I once had a 500GB Seagate HDD that developed some bad sectors due to a severe power fluctuation. Not having a replacement on hand, I gingerly continued to use it. When it didn't cause any problem in operation, I became complacent and continued to use it for a few more years until I upgraded to a 1TB drive.Thanks. I have already copied data. No errors. This is totally asymptomatic other than RT-PCR (HD-Tune) test.
So, should I throw this or there might be someone interested in buying it at "some" price?
A detailed scan with HDDScan showed two bad sectors about 100 sectors apart near the end of the disk.
It just so happens that I had a reason to connect that 500GB drive to my computer last week. SMART shows the reallocated sectors but it's still working fine with nearly 34,000 power on hours count and 10,000 start/stop count
