I bought “My Book Studio II”, and it is mainly for storing my work files at home taken from my office. It is using RAID 1, so I thought it should be safer.
I tried the followings to test the drive work probably with RAID 1, but no luck.
Taking Slot A WD HD out, and install this hard drive into another 3.5" HD enclosure.
Copy a file into Slot A WD HD.
Put Slot A WD HD back to the “My Book Studio II”, without connecting the computer.
Switch on the “My Book Studio II”, and let it rebuild RAID.
Connect “My Book Studio II” to my computer when the LED glow steadily after around 5 hours.
I found the files I copied before were lost after RAID rebuild. How RAID 1 exactly work? It might be happen when one drive failed, and replace a drive, then rebuild RAID, and losing files?
Any steps I was missing? Your helps or experience are very appreciate. Thank you.
