For some time now I’ve had issues with SATA bus-errors once in a while. The latest occurrence was a few days ago, a day after I had made a full backup.
Less than 1MB/s is not exactly normal. Usually I get about 90MB/s from that disk.
I couldn’t really explain it, the disk was / is fine [works now – as usual].
After some head-scratching I remembered I had unplugged the disk, as I was messing with “secure delete” on an external USB disk – and didn’t want to shoot myself in the foot. That didn’t work, so I just wiped it and after that was done plugged the SATA disk back in. It appears that the trouble started afterwards.
Anyhow, thanks to a different SATA cable, everything is back to normal again.
BUT… I wanted revenge!
I present to You, the headless snake!
