This looks like a duplicate Chinese products and as the look goes so does the performance. It keeps getting disconnected and a lot of error messages. Tried with different laptop and found out that this hard drive itself is defective. I wish I had gone with Seagate or other brands.
There is reason behind cheap prices. This is because it’s made of cheap material. Not only doesn’t this portable hard drive from toshiba is cheap - very light, cheap plastic body & most importantly not durable. The product didn’t arrive as a defective one. After using for about one month(actually less than 3 weeks) it no longer works. You see the main problem is that this cheap device can’t endure. Worst of all I lost my data which is what happens when HDD have issues like this , indeed an irreplaceable damage .
Save your money and buy Western Digital Passport or similar product. Though they are slightly expensive it’s worth it. No warranty can save your data !
