What I can try
Failing disks, some SSDs, USB sticks, memory cards and laptops that no longer boot.
Data recovery
If the files still matter, stop using the drive.
I can often recover documents, photos and work from failed or unbootable storage. It is not a guarantee.
Do not keep switching the machine on to “see if it works”. That can finish a drive that still had a chance.
What I will tell you first
Whether an attempt is sensible, and if a specialist lab would be better.
Afterwards
Move the files onto a new drive and set up a backup.
Get in touch
Call, text, WhatsApp or email. I aim to reply the same day. Happy to talk it through before any work.
Send a photo of the problem. A picture of the machine or the on-screen error is enough — attach it in your email app (this link only starts the message).
