"I ordered this on January 18, 2026, and got delivery within just 2 hours - super fast! But the drive came in a plain envelope without any bubble wrap or box safety, even though it was a brand box inside. That was my mistake - I should have rejected it right away due to improper packaging.It worked fine initially, but on February 1st, it suddenly stopped working completely - wouldn't power on at all. When I contacted Amazon support, they said the return window was closed, so I had to file a warranty claim with Seagate.Contacted Seagate support -they first offered a refurbished replacement, which made no sense for a brand-new purchase. After a long discussion, they finally agreed to send a brand-new drive, but I had to ship the defective one to their Chennai office first. It took me 3-4 days to find a courier, but then I contact Seagate again and discussed and they said they provide free pickup services, so no extra cost there. However, the new drive would only ship 10 days after they receive the old one. The confirmation PDF didn't mention "new" - it only said used/refurbished, so doubt remained.I contacted Amazon again. The first agent started a return/refund but later refused saying the lead team denied it. Had a long call explaining the whole issue. They said if Seagate is denning for replace in that case i have to send Amazon an official mail from Seagate with denial of replacement and then only Amazon will refund me otherwise, they won't refund. It felt like a scam - seller is deliberately sending defective items with poor packaging.Checked reviews: multiple users had the exact issue - HDD failing within 15 days of purchase, no Amazon support, and Seagate sending refurbished drives despite high price paid.No choice but to proceed with Seagate's free pickup. But hours later, Amazon emailed that my return request was approved! Somehow, the item was returned successfully, and I got a full refund.IF YOU WANT TO BUY THIS ITEM FROM HERE THINK 100 TIMES. THE SELLER IS DOING SCAM.YOU CAN FIND MORE REVIEWS SIMILAR ISSUE HAPPENDED WITH THEM."

As a MacBook user with very less memory space on my variant this is life saving. Great for backups and extra storage for pics and videos and other important docs to carry around or save. Tho you would need a separate cable with this one on a Mac. The one that comes with it isn’t type c compatible. Lightweight as well. Not as heavy as I was expecting. Looks smart as well. Easy to use. An expensive but valuable investment. Got it on sale. So worth it!
