hi guys, does anyone can recommend a freeware or any tools to recover a raw hdd drive. The system was suddenly corrupted, hdd can still be detected and shown on my computer but upon clicking on the icon it's asking me to "Reformat my hdd".

When Windows prompts to "Reformat" a drive and labels it RAW, the OS simply cannot parse the filesystem. Common causes include a corrupted partition table, damaged filesystem metadata (for example the NTFS Master File Table), or physical sector failures. If the data matters, avoid any writes: every write can reduce recovery chances.

Safe-first workflow that works in most cases:

  1. Stop using the disk immediately and boot from a Linux/live USB so the drive stays unmounted.
  2. Check drive health (SMART) before heavy work; a failing drive needs a different approach than a logically corrupt one. On Linux, smartctl -a /dev/sdX reports SMART data.
  3. Make a full sector image to another drive and work from that image. For problematic disks, imaging tools that retry bad sectors are preferable. Example using GNU ddrescue (two-pass approach):
ddrescue -f -n /dev/sdX /path/to/backup/image.img /path/to/backup/image.log
ddrescue -d -r3 /dev/sdX /path/to/backup/image.img /path/to/backup/image.log

Always operate on the image, never the original.

Once you have a verified image you can try non-destructive recovery steps: inspect and rebuild partition tables, attempt metadata repair, or run file-carving on the image to extract files. If the drive shows mechanical or electrical problems in SMART, stop and consult a professional lab — further DIY attempts often make things worse.

Given the thread: was correct that a bootable recovery environment is useful, and was right to point to low-level tools for stubborn problems. Since had a verified backup and chose to format, that was a pragmatic solution. For the future, keep periodic full-disk images (not just file copies), verify those backups, and monitor SMART so issues get caught before a corruption event.

Hello,

If this is a one time thing and I suggest downloading UBCD for windows. It is a bootable CD that has partition and file recovery tools available from the system after it boots.

If the data is critical look into photo-rec and testdisk which are free or purchase and R-Studio and their applications.
