How and Why You Should Totally Power Off External Hard Drive When Ejecting

Unplugging Flash Drive after you ejected it is what people usually do even if the LED light is still blinking or still have light. In Microsoft’s earlier version of Windows operating system like Windows XP, LED light will be automatically turned off after you successfully ejected your flash drive. In Windows Vista and 7, Microsoft included a feature that even if you successfully ejected your flash drive LED will continue to light so that you can still charge external devices like your phone, mp3 players, cameras, etc. then remove it later safely. But what if you’re using external hard disks? Flash Drive and External Hard Disks are totally different because Hard Disk has moving parts. There are many people reporting to Microsoft that this feature may cause damage to their external hard disk.

Types of External Hard Drives

HDD (Hard Disk Drive) – Composed of moving parts therefore more sensitive to shocks. Low price and more affordable than SSD.

SSD (Solid States Drive) – Extremely fast and extraordinary expensive compared to HDD. SSD has no moving parts making it less susceptible to physical shock, runs quietly and have lower access time compared to HDD.

Numerous reports have been posted to Microsoft’s website stating that their external HDD is still spinning even successfully ejected. This is a big problem and concerns many people since removing it while it spins can eventually damage your external HDD if not instant. If you’re using external SSD then there’s nothing for you to concern since SSD has no moving parts.
