📎 AI Summary:
The thread discusses a user experiencing issues accessing and formatting an Android OS partition installed on a HDD, which became unrecognized and inaccessible in Windows 7 after an unsuccessful installation attempt. The user cannot open Disk Management or use third-party tools to format it, including via Command Prompt. A responder suggests that if it's a separate disk, the issue might be with the disk itself, but if it's a partition on the same disk, Windows should handle it as unused space, and recommends using a live Linux distribution like Ubuntu with gparted to reformat the partition. The overall tone is helpful and troubleshooting-focused.

Hi,
I was trying different Android OS that I was installing in a HDD Partition (J:\). It was EXT4 Mounted Partition & lastly I came upon a Android OS (it was unofficial) & after unsuccessful attempt to install. I booted into Windows 7 & tried to format it but it was neither opening or formatting the method I have created, mounted, formatted partitions many times & this issue never appeared but now its not accessible. Plus, I cant open Disk Management nor Third Party tools I tried formatting through Command Prompt but no luck. 🙁
Any help will greatly be Appreciated.

-Thanks

If it's a separate disk then it could be a issue with the disk. If it is truly a partition on the same disk and Windows then it should format without issue. Windows would just see it as unused space. If it's not accessible from Windows I would download and boot to a live Linux distro such as Ubuntu and format the partition with gparted.
