Data Recovery on Windows: What to Do First

Stop writing to the drive

When you delete a file, Windows does not erase it. It marks the space as free, so the data can still exist until something overwrites it. Microsoft’s own guidance is to minimise or avoid using the computer after losing a file, because even ordinary activity creates files that can claim that space. Close your apps and do not save anything new to the affected drive. On an SSD, deleted data can often be cleared sooner, so speed matters even more.

Check the easy places first

Most lost files are not really lost. Before reaching for tools, look in these places:

• Recycle Bin: sort by Date Deleted, then right-click the file and choose Restore.
• OneDrive: sign in on the web and open its Recycle bin, which keeps deleted OneDrive files for a limited time.
• Previous versions: right-click the folder, choose Show more options then Restore previous versions. This only works if File History or System Protection was switched on.

If the file is in none of them, search for its name across the whole drive before assuming the worst. A file saved to an unexpected folder, or renamed by an app, looks exactly like a deleted one until you search for it, and checking costs nothing.

Try Windows File Recovery

If the files came off a healthy drive and are not in the Recycle Bin, Microsoft’s Windows File Recovery is a free command-line app from the Microsoft Store. It cannot recover files from cloud storage or network shares. The format is winfr source-drive: destination-drive: /mode, and the two drives must be different.

winfr C: E: /regular /n \Users\<username>\Documents\

Regular mode suits recently deleted files on NTFS drives. Use /extensive for older deletions, after formatting, on a corrupted disk, or on FAT and exFAT drives. Recovered files land in a Recovery_<date and time> folder on the destination drive. If you are unsure, Microsoft suggests starting with Regular.

When software can’t help

Recovery software only works on a drive that can still be read. Power the drive down if you hear clicking or grinding, if Windows does not see it at all, or if it has been exposed to water, heat or a hard knock. Repeated power-ups can turn a recoverable fault into permanent damage. These are physical failures, and they need specialist equipment rather than another download.

Choosing a professional lab

Labs open drives inside a cleanroom, repair or replace failed parts, then read the data. If you need one in Singapore, CBL Tech is a local option; its website describes an in-house cleanroom and a free diagnosis, so you can learn what is wrong before agreeing a price. With any lab, ask for a written quote in advance and find out what happens to your data afterwards.

Make the next loss painless

The best recovery is a restore. Set up Windows Backup and File History as shown in our guide to backing up Windows 11, and keep one copy off-site. Be careful with a factory reset, which wipes the very drive you may still need to recover from. Keep Microsoft Defender running so ransomware does not decide for you, and consider a mirrored pool with Storage Spaces for drives you cannot afford to lose.
