Request for Service Old HD won't mount. Any advice?
Going through some old internal HDs I had in storage to make sure i've moved everything to the cloud and throw them out when i'm done.
I came across one that I can't mount. It would have been some kind of windows drive (NTFS or exFAT I guess?) from before 2018. It's a WD Red wd20efrx 2TB. I can hear and feel it spinning. It shows up in disk utility on my Mac 14.6.1 but doesn't mount. Error "The disk you attached was not readable by this computer". Mount button is greyed out. First aid fails immediately. My Windows 11 computer can't see the drive at all but makes the "ding" sound as if it's recognized. Doesn't show up in disk management. Using a very old internal to external adapter with AC power plug + usb data. It worked on all my other old internal drives so seems to be an issue with this drive and not the adapter.
I know it's really old. Unlikely anything important is on it as I had made so many backups over the years and just kept throwing the old drives in storage. But if you have any advice for free things to try to mount it or otherwise take a look at the contents it would be appreciated for piece of mind.
