How does Storage Space identify a weak drive?
I had a storage space on my behemoth homegrown Windows 10 22H2 PC. I seem to have used too much power and am now about to replace the power supply. To reduce power I moved my Storage Space from internal SATA to external USB
The move from internal SATA to external USB was uneventful. The Storage Space appeared as expected. However, Storage Space identified Disk #2 as being a candidate for replacement. It did not say what was wrong with it. It also did not say whether Disk #2 was which serial number.
I have learned through bitter experience that there is no way to identify which drive is which. I would have thought that the drives would have the serial numbers embeded in firmware.
So I chatted with Western Digital. They had no solution, but referred me to their application "Dashboard" which has serveral diagnostic tests.
I could not get Dashboard to recognize the external USB enclosure, so I removed the two WD hard drives and transferred them, one at a time, to a one-drive USB enclosure. Although the PC did not recognize it, the Dashboard application still functioned. It said that both drives were just fine based on the SMART test.
So my question is "What does Storage Space know about the hard drive that the SMART test doesn't?"
