Cant access USB Hard Drive ExFAT in macOS , but its working in windows

[qwezxc]

Hello,

Today I was working in my usb 6TB WD_BLACK in mac os (macbook pro 14 m1) , everything was working fine, I close the lid and when I came back to work again the disk wont show in finder, but its grey out in Disk Utility.

The usb hard drive works great in windows, what should I do ?

Put the computer to sleep and pull out the USB and plug it back in after waking up the computer?

I close the lid, after one hour (+-) , came back the disk did not show up.

Restarted the computer multiple times same problem, tried in another macbook (mb air m1) , same problem.

Is this an older drive? Invert the USB-C adapter plug in the USB-C connector.
"Sidedness" is supposed to be only an issue with USB 1.1, but who knows?

Its a new drive.

The HD is usb, i have an adpter like so :

I tried both ways, I also tried another with multiple adpters in another macbook m1. Same problem, this is so confusing . The disk powers on.

Reboot your laptop.

Reboot your laptop.

already did, multiple times.

After using windows built in tool check disk for errors, it worked . lol , i dont know what happen.

restarting solves 99% of all problems

ExFAT is a notoriously unreliable format. Your drive probably went corrupted and macOS refused to mount it. Windows had less concerns. Disk check would have fixed that. You still probably have corrupted files on that drive though.

This is always the best approach when you have access to a Windows machine.

I use several ExFAT formated HDDs daily, on both macOS and Windows, and have done so for the best part of the last decade. I've had very few issues, but 100% of the issues have involved use on macOS. My Macs seem to very occasionally damage to drive format. This may be related to the macOS's sleep functions and its issues with unmounting drives while its dreaming and its faillure to properly remount when awakened. Mac's Disk Utility can't handle these damaged volumes but Windows' repair services seem to always do a good job.

ExFAT is a solid drive format, though it lacks some of the ruggedness (duplicate directories, ...) found in NTFS and HFS+. The Windows implementation has been solid since late in the WinXP days, but Mac implementation (intro OSX 10.6.5) seems to have been less stable, at least in my experience.

Did you try using Disk Utility on the Mac before that?

If not, next time you can’t mount a drive, use Disk Utility since it can often repair unmountable drives.

The only time as Mac user was use ExFAT was in Intel days for Bootcamp the Windows installer could see it and refit it NTFS before installation!

Everything is working fine, check all the drive, no corrupted files. Also the drive is new.

Yes, every option wouldn't work (did not test erase or restore).

What type of file system do you recommend ?
I have to work with that Hard Drive in windows, linux and macOS.

I have no experience with Linux machines in radio stations (my friend owned a radio Station) and it ran on Lixun servers and workstations! Only on time when old Ethernet cable failed did we have any problem running that system!

The format in networked device doesn't really matter! What matters in network is the shares be able to read/write to certain shares! You better of going with a smart NAS setup to share data points and archiving!

Well, sure, the original disk check probably fixed whatever was wrong. I mean, the mere fact that running the disk aid on Windows "fixed" the disk for macOS is a clear give away that something has been changed.

no corrupted files.

How do you know that? Did you maintain checksums for all the files on the drive?

Also the drive is new.

Bugs and other problems with filesystems affect drives regardless of whether they are old or new.

Geez. Give the guy a break. His drive works and he's happy. Why would you want to rain on his parade? (rhetorical question) Yish!

My suggestion:

Try a different CABLE setup.

Does the WD drive have a "detachable" cable (at the enclosure end)?

If so, get a cable with USBc "on the Mac end", and USBa (or whatever the drive is using) on the "drive end".

No promises.
But sometimes, making simple changes like this... changes everything.

Yes ,

Yes, I ll buy one, for now i'm using the adpter, was the fastest way to access that hard drive, I had my developer projects in there.

Yes, I'm made sure the drive is ok, I have alot of projects there, that my work depends on.

Problem keeps happening, after a call with apple, they said the adpter is the most likely causing this.
