I have a Seagate 1 TB external drive (2N1AP4-500) (USB 3) that I've used with Win 10, Linux and even as a usb connected drive to a Synology NAS box. But now Windows (10) doesn't recognize it. It's formatted NTFS and I can read/write to it from a Linux box, or from the Synology, but not from Win 10. Win 10 reports it as used space 0, free space 0 when I look at properties. Management lets me assign a drive letter, and reports it as Online, healthy, and primary partition of 931.51 GB. I've tried Windows "management" to re-format, reformatting using Partition Magic, and windows still doesn't let me write to it or read from it. Anyone have any suggestions?

BTW, I was a Newsguy user to access the group for years, until they suddenly went bankrupt. I can READ the group from newsgroup ninja, but haven't figured out how to post from there, hence the need to post this from google Groups

You can set up an account using AIOE. It is an NSP
that does not require a username and password, to post.
The details are here, as to port numbers. Since you're
not sending username and password, there is less need
for anything other than the default port 119.

They show a picture of a read-only symptom here.

https://www.diskpart.com/screenshot/en/others/others/copy-failure.png

The article is here. I've copied out an interesting part.

https://www.diskpart.com/windows-7/external-hard-drive-read-only-in-windows-7-0310.html

"Run Diskpart as administrator

[Administrator Command Prompt will do]

diskpart

list disk # returns a numbered list of disks
select disk 3 # Assume the third disk is the 1TB one
attributes disk clear read only
exit
"

( This implies sector 0 has some means to record "read-only" ? )

Then you can enter Disk Management and have a look.

*******

The diskpart command can also do this

diskpart

list disk
select disk 3
detail disk
list partition
select partition 1
detail partition
select partition 2
detail partition
exit

The idea there is, it can display information about the disks
and partitions in the system. But it requires selection,
to tell the program exactly what you want.

As can fsutil, but only for NTFS.

fsutil fsinfo ntfsinfo X:

That would display information about NTFS partition X: .
It will show cluster size as well as a bunch of other numbers.

Note that it is possible, using Windows 10, to format a partition
to a very large cluster size, like 1MB per cluster. But then if
you plug that same drive into Windows 7, it goes "what the..."
and refuses to work. And that's because Windows 7 cluster
support stops at 64KB.

If you are using exotic cluster size choices, try to limit yourself
to 64KB, as that works everywhere. The new Win10 capability is nuts.
It violates one of the first rules of running a computer room.

OK... Diskpart says:

Note that here diskpart indicates the disk is offline, but Disk
Management in windows says the disk is online.

(I split the disk into 2 partitions just to see if I could get a
portion of the disk to be accessible. Didn't make any difference.)

Soi I tried to change it to online with diskpart:

Well, I wasn't expecting that.

I didn't know partitions could individually be offline.
I only thought disks could be offline (mainly caused
by the diskID being identical on two disks -- they hate that).

Did you notice that the offline command accepts

offline disk # which you tested
offline volume #

online disk #
online volume #

So maybe you need something like this:

list disk
select disk 3
detail disk
list partition
select partition 1
detail partition
online partition
select partition 2
detail partition
online partition
exit

That sort of thing.

OK, looking back, I see the reason I got the error was a misspelling of partition.

OK, here's an update. I finally got Windows to "see" this disk. I tried formatting with Linux to both NTFS and FAT32, and neither worked. That is, windows still couldn't see the drive.
So I went bact to attching it as an external drive to the Synology NAS box, and formatting it to FAT there. That worked, and Windows was able to see it and write to it. So I then used Management under Windows to reformat it to NTFS, and that also worked, so now it's seen and connected to Windows.
Many thanks for all the suggestions.... even tho using Diskpart didn't fix things, I did learn a lot.

I found another article, for future reference.

https://docs.microsoft.com/en-us/troubleshoot/windows-server/deployment/system-partition-offline-install-3rd-party-disk

"Diskpart

List volume
Select volume 1 (Considering this is 100-MB system partition)
Online volume
exit
"

So it looks, to be successful at it, it's a volume reference
that is needed.

"Assigning the drive letter will ensure the volume [will]
not [go] offline again after a reboot.

The volumes may go offline if AUTOMOUNT is disabled either
while using a third party storage software or if the user
manually disabled the AUTOMOUNT for the volume. To check this,

Diskpart

select volume 1 # Automount is a per-volume feature

automount # returns the status
# Automatic mounting of new volumes is disabled.
# To enable AUTOMOUNT, run the following command

automount enable # Automount now enabled on Volume 1
exit

Reboot the server and the volume will not go offline.
"

HTH,
