But overall, it does seem like Hitachi and Seagate are the most unreliable manufacturers of them all. Seagate and Western Digital, on the other hand, have the most recorded drives, so their numbers will be the most accurate. The results would be far more accurate if Secure Data Recover had an even distribution of failed drives from all six manufacturers.Īs a result, lower disk counts of Hitachi, Toshiba, Samsung, and especially Maxtor have to be taken with a grain of salt. Thankfully, the rest of the six manufacturers were not as bad as Hitachi, with Toshiba turning up with 1,884 bad sectors in total, Samsung with 529, Seagate with 2,671, and Western Digital with 628.ĭespite the significant variance in power-on hours and sector errors between drive manufacturers, we can't take these results at face value. But the best-performing drives in this category come from Maxtor, with just 228 bad sectors found. Again, Hitachi was by far the worst-performing manufacturer, with 3,348 bad sectors across the same 211 drives.
Secure Data Recovery also recorded the number of bad sectors on each drive.
