I have a very strange problem with a WD Blue 1TB drive, which I used as a second storage drive in my PC. I was in the process in copying everything from that drive to a new location, when suddenly the speed starts to declining till it completely freezes.
So I tried rebooting the system, but with the HDD drive (connected via SATA) Windows refused to boot, although it’s installed independently on a SSD.
So I dismounted the drive from the PC and connected it via an SATA-to-USB adapter and now things started to get strange.
The partitions are recognized, but this takes about 5min to accomplish this by Windows and the same goes for accessing the file system like directory listings. Copying is nearly impossible, only very small files (< 100kB) could be copied and that took about minutes.
I checked for SMART errors but nothing is stored and the HDD doesn’t make any strange noises during operation and speeding up.
I also tried LINUX for accessing the data, but it behaves even slower than Windows.
Does anyone have an idea what went wrong with the drive?
