I just brought a brand new WD My Passport Ultra 2 TB today.
After formated it to be MAC OS Entended journaled Enscripted
I partitioned it to be for store data and for backup.
After load 1.2 TB of data in to it. Now i start “notice” a nasty noise.
It sound like when normal hdd seek or write data, except it 200% louder, 300% more frequent.
So I use WD bundle sorftware to test, for a SMART and QuickDriveTest the result is pass. Then i use BlackMagic to test the speed, the result is 60 MB/s and 70 MB/s in write and read accordingly.
All seem fine, but the sound really worry me. It remembrance me of my failed HDD in the past.
So i record it with my iphone point blank to the HDD. Here is the result.
I sound like a grinding combine with a random “dudd” sound. Here is it.
