Ext hdd became very slow...

[Alex6969]

Hi, I have two identical Buffalo ext hdd, one of them today started to be verrrry slow, writing a 50k data took 25mins.
I tested the hdd on another laptop, with no problem. It must be something with the hdd and my macbook pro running monterey. But the other hdd on the same macboo pro is fine.
I noticed that when the drive is connected, the icon also appears under network on Finder, also takes lonftime to load and eject.

Any idea how to fix this?
thanks.

Hello and welcome.

• Which exact model MBP?
• Which version of macOS Monterey?
• What is the exact model of the Buffalo HDDs?
• How are you connecting the HDDs to the MBP?
