I have two identical Elements SE 5TB drives, as well as a Seagate Ultra Touch 2TB, whereby I use one Elements drive for daily use (let’s call it drive “A”), and then at times I back up to the other Elements drive and the Seagate drive (we’ll call them drives “B” and “C”, respectively) for data redundancy. From the first time I ever used any of these drives individually they have never given me issues, and for months when I backed up from drive A to drives B and C the data transferred without a hitch. Now, within the last few weeks, when I attempt to back up data from drive A to either drives B or C, the transfer is extremely slow and drive A clicks occasionally during the process. Naturally I thought at first drive A was mechanically failing, but not only has it checked out as physically fine when testing for drive integrity, but when I transfer files to any thumb drive of any size this same issue does not crop up, nor under typical daily usage of reading or writing to drive A does it operate slowly nor does it ever click.
I can’t figure out what is going on, either why the slowdown or clicking issue started in the first place, nor why it only affects hard drives but not thumb drives. If anyone has insight or suggestions I’m all ears. Thanks so much!
