when something says that your harddrive has lost clusters
what does this mean and how can you fix this?

Basically, a small part of the hard drive has become unusable. Can be many causes, but quite a few times it indicates the imminent failure of the drive if it keeps happening. A very sharp knock while hard drive is running or failure of some magnetic material on the disk can cause it.

I think you are confusing lost clusters with bad sectors.

Lost clusters are marked as "in use" but no stored file is actually linked to them.

Lost clusters are usually the result of interrupted file activity of some sort, where a program will allocate some clusters to a file it is building, and if the file is not properly finished and closed, the clusters never get correctly linked to a file name.

Depending on your operating system you can use chkdsk with the /f switch to convert them to separate files, and then delete them...or view them in notepad to see if they are that long lost letter you have been looking for...

lost clusters is basicly lost info on the harddrive. bad sectors usually means the hardrive is on its way out.

These days, you use scandisk rather than chkdsk. :D (Or is it still chkdsk in NT?)

But yes, lost clusters are not usually a sign of hardware problems. It's usually a software crash/powerfail while writing.

Its Scandisk that gone in XP. Chkdsk is still there.
