USB/SATA External Disk Backup – Recent bug or stupid design decision
We have a variety of external disks (150+ over many sites) that we attach to the NAS for external backup that are taken to off-site storage. It is part of the normal operational routine. Been worki...

Whatever the ReadyNAS system does needs to be corrected – having a disk that is not usable at all because of a failure to dismount is simply wrong.
Typically the read-only status occurs because the "dirty" bit on the USB disk is set when the disk is mounted (which normally is cleared when the disk is properly dismounted). Windows will see this and offer to repair.
Do you know what format the disks were using?
Did you try these mitigations: https://www.easeus.com/storage-media-recovery/fix-read-only-error-on-hard-drive.html
These are only external drives that attached via the rear SATA/USB port of the ReadyNAS.
They were formatted as NTFS drives. They have been in use for the past six plus months. Now we have failure.
Stuff used to work but now the drives are not recognized by Windows 11 or Easeus. If not recognized then it is impossible to change any values or repartition or reformat.
My sense is that the ReadyNAS OS/system has 'fiddled' with the drive in a way that does not allow them to be recognized on a Windows system.

If the file system somehow became seriously corrupted, then it is possible that Windows wouldn't recognize the format. However, if EASEUS was subsequently able to re-partition the drive, then Windows should certainly be able to format it.
After you repartitioned the disk, did you re-initialize and format it with the windows disk manager?
Have you tried using Seatools in the PC?
This issue gets more interesting.
Here is the ReadyNAS admonishment about read only.
Took the drive to a Windows 11 system and ran EaseUS after a clean workstation boot. Drive was seen.
No Windows admonishment regarding repair or the equivalent.
Can open the drive in File Explorer.
Can copy data to the drive using File Explorer. Disk Manager sees the drive as well.
Seems like it is OK in the Windows system. It is obvious that the file system is not corrupted or damaged.
Took the drive back to the ReadyNAS and received the same error message.
Something hinky here – works in Windows but ReadyNAS blocks it. Could this be a result of the recent OS upgrade just released?
By most standards this is an operational anomaly.
Of course we just want it to work like it used to. Just received another report of same problem from a different location.
As an additional comment, this is a perfectly fine and operational off-site backup drive that we rely on for operations in case of a disaster. Reformatting or partitioning the drive does not work since the data gets destroyed.
At this point we have three such drives that have occured in the past several days.
