Stop using the affected disk and avoid any writes to it. Whether Windows still boots (the diagnostic raised) changes the next steps, but the safest universal strategy is: make a sector-by-sector image of the failing drive to a different physical disk, then work on that image. If the drive is producing clicking, grinding, or heat, treat it as a probable physical failure and do not power it on repeatedly — consult a professional recovery lab.

A practical, widely used workflow for non-physically-failed disks is to boot a rescue Linux USB and image the drive with a tool that tolerates read errors. Example commands (run from a live Linux session, with the destination on a separate drive):

sudo ddrescue -n /dev/sdX /mnt/backup/disk.img /mnt/backup/disk.log

sudo ddrescue -d -r3 /dev/sdX /mnt/backup/disk.img /mnt/backup/disk.log

First pass (-n) copies everything it can without aggressive retries; the second pass (-d -r3) does direct reads and retries. Read the ddrescue manual before running: GNU ddrescue.

After you have a good image and log file, run file-recovery tools against that image, not the original drive. Also check SMART to get a health summary (example):

sudo smartctl -a /dev/sdX

See smartmontools.

Tying this back to earlier replies: is correct that out-of-Windows, low-level tools are often needed; imaging first preserves your ability to try several tools safely. and were right that working from another machine can help — just make the image first. If the data is irreplaceable or the drive shows physical failure signs, stop DIY attempts and contact a professional recovery service.

hi, i think a really good recovery program is needed for recovering data in corrupt sectors/clusters, spinrite recovers the data and marks sectors so no data will be wrtten to them ,it depending on hdd size it can take days to run it fully ,it boots to the cd [worth it cost ] ,so windows isn't running .http://www.grc.com/spinrite.htm

You can also try this;

Remove the drive from the PC.
If you have another working PC or can temporarily borrow one, slave the drive and recover your data.

Due to bad sectors or many other problems i have lost my important data

free and basic file recovery tools are not going to be of much help with recovering files from bad /damaged sectors.!!just my opinion

Get other primary hard disc, put that on slave and find some recovery program and recover it

I agree that a good software is required even if it is not "bad sectors" but "many other problems" good software is necessary.
"Due to bad sectors or many other problems i have lost my important data,"
I have successful used and have read that "Recuva" is a good, free software. I am sure that the one you have suggested is much better and therefore, worth the cost. As the OP stated it is "important data".
