Notably, 74.5 percent of the HDDs came from either Western Digital or Seagate, which Secure Data Recovery noted accounted for 80 percent of hard drive shipments in 2021, citing Digital Storage Technology Newsletter data shared by Forbes. The firm also determined the drives' current pending sector count, depicting "the number of damaged or unusable sectors the hard drive developed during routine read-and-write operations." The company's data doesn't include HDDs that endured non-predictable failures or damage by unexpected events, such as electrical surges, malware, natural disasters, and "accidental mishandling," the company said.Īmong the sample, 936 drives are from Western Digital, 559 come from Seagate, 211 are Hitachi brand, 151 are Toshiba's, 123 are Samsung's, and there are 27 Maxtor drives. Secure Data Recovery's March 8 post broke down the HDDs it received for data recovery by engineer-verified "power-on hours," or the total amount of time the drive was functional, starting from when its owner began using it and ending when the device arrived at Secure Data Recovery. "Most" of those drives were 40GB to 10TB, according to a blog post by Secure Data Recovery spotted by Blocks & Files on Thursday. The statement comes from a Los Angeles-headquartered HDD, SSD, and RAID data recovery firm aptly named Secure Data Recovery that has been in business since 2007 and claims to have resolved more than 100,000 cases. Īn analysis of 2,007 damaged or defective hard disk drives (HDDs) has led a data recovery firm to conclude that "in general, old drives seem more durable and resilient than new drives." Further, eight of the 13 SMR drives from Western Digital and Seagate registered fewer than 15,000 power-on hours on average. The firm found that, "Western Digital's SMR models had a 12.7 percent shorter lifespan than their CMR counterparts, Seagate's SMR models had a 19.7 percent shorter lifespan than their CMR counterparts," when looking at average power-on hours. It said that 37 percent of the Western Digital and Seagate drives analyzed featured SMR. Update : Secure Data Recovery provided us with a little more information on the defective HDDs tested.
