Laptop HDD has 800Gb of bad sectors – is there a fix?

Have been singing the praises of my Lenovo Ideapad Y580 but after doing a routine CHDDSK it turns round and tells me it has the following:

Which equates to suddenly having only 19Gb of free space instead of 800Gb on a 4 month old 850Gb HDD (partition).

Are there any tools to fix this? Warranty is the usual send away and wait, so am loathe to do that unless absolutely needed.

Cheers all

Defrag
If there are still that many bad sectors afterwards I would draw it to Lenovo’s attention.

Defrag really?! I was thinking a full reformat.

genuinely interested, whats the reason behind defraging to solve bad disk sectores? i thought one was to do with logical data and the other physical disk?

I was thinking of that but read about people making things worse by defragging. Also can’t see how that can improve any physical damage if that’s what’s happened.

I’ve only got a few files on there to back up as most data is on D:. Oddly the machine is still running perfectly well – just like before I did the CHKDSK. I guess those bad sectors were already there but not brought to its attention until the scan.

Get your data off it asap. Get a replacement from Lenovo.

as above, get a back up done (do not overwrite any existing backups that you may have!) and get it replaced.

do not overwrite any existing backups that you may have!

Good point – you cannot rely on the data that you get off to be good, so overwriting a previous backup on external media would be a decidedly bad idea.

10 day RTB turnaround with Lenovo according to CS team. Looks like it’ll have to head back for repair 🙁
