I'm having problems with both of the above and having tried a few things suggested on forums they are still not working.

I get the message and Disk "Defragmenter cannot start" and "Windows was unable to complete the disk check"

I've tried running chkdsk from startup but that doesn't work either - it says it cannot be prformed on a RAW disk, even though my hard drive is NTFS.

Any advice?

If disk defragmenter shows RAW partition, your partition table has got corrupted.

My bit of advice would be to backup all you can from all partitions of your hard disk and repartition and reformat your hard disk. Use full format when reformatting.

You may also want to download disk diagnostic tools from your hard disk manufacturer's website and try to repair the exisiting partitions. In any case, data loss is a high possibility.

I suggest trying recovery software.

A partition seen as a RAW file system...either has NTFS problems or hard drive problems, IMO.

There are free and paid versions of recovery software...and some programs are better than others.
