Seagate Expansion Portable Hard Drive light is blinking

The drive mounted, but the light is blinking, no activities, why? In fact, 2 of them started on the same day.

I tried restarting no help. It does not blink before I enter the password on my Mac, then starts again. Thanks.

iMac 27″, macOS 10.13

hard drive not showing up I have a Mac Air (earlier model, Mac Air 13 maybe ? I received it from school around 2019 I think?) and desperately need to clear some space. Just bought a new Seagate Hard Drive 2TB... plenty of space, brand new. The problem is, the hard drive isn't showing up. Light is flashing and it's making a beeping noise, but nowhere on my Mac. I'm not exactly tech savvy either...

Seagate External HDD stopped working My Seagate Backup Plus Portable Drive stopped working. It was in storage for two years. I pulled out to work with an old iPhoto library. I left it plugged into my computer for a few days. Slowly it stopped working. It started taking longer and longer to do things. Then it started crashing my computer. Then after a restart from a crash it simply disappeared. The light is on. It sometimes making spinning noises and it sometimes just hums. It does not show up in DiskUtility. It does how up under System Information. It does work on my other Macbook either. I have tried different cables and different ports. I am attaching a few files so you can see my computer info and where the HHD shows up. Any and all suggestions are appreciated.

External Seagate Disk (1T) restarts my macbook everytime I try to use it Hey guys, I have a macbook pro, (early 2015, macOS Catalina version 10.15.7) that restarts everytime I try to use my external seagate 1 Terabyte disk. Everytime I try to browse its content (for example, trying to copy its content to another external disk) after a few minutes, it restarts my computer...it goes totally black for a couple seconds to later display a message that says something like "your computer restarted due to a problem" (it does NOT disconnects due to going asleep, it literally crashes and restarts my laptop). I feel the main issue is the disk as I already tried to use another macbook and did the same thing. any idea what could be going on or what could I do to rescue my data? thanks in advance guys! Marco

Yes, likely Spotlight or Time Machine accessing it.

The Blinking indicates the computer is reading the external drive. The drives get Power from the computer so until the computer is turned on - no power to drive(s) - no blinking.

The reason I posted because it was blinking for a long time, maybe because it was connected for a while, as it's a backup of the backup.

Thanks!
