Disk Health

It appears that windows has found some bad clusters and repaired them. There was data in those clusters. Those files are probably alright.

If You would like a small app to check disk health search the net for "Crystal Disk Info". It is a freebie. Just be careful where you download it from.

Hi Slartybart - yes this is a valid user

Hammerhead - Thanks for your thoughts, I will have a look at the software you've mentioned. Are bad clusters something physically wrong with the drive or would they disappear with a hard drive format. It is my intention to do a clean install but was really wanting to know if it would be better to install a new HDD first...

The Log file from ChkDsk also contained a log from when it ran in 2013 - I have attached the full log (was to long to copy and paste here)

This looked longer and like there were more problems. The reason I am looking at the machine is that it is very slow to startuo and can be a bit crashy!

Any advice welcomed, thanks

Disk Age?

How old is this disk? The log file you included in your last post showed problems. Install and use the disk health check app we discussed. I would say this disk is on its way to failing. It may last longer but who knows. I would be looking at some new disks, an ssd maybe.

Thanks - HPC AV is a valid user.

Bad sectors/clusters normally indicate a physical defect on the disk - all disks have bad spots, even new ones (mfgr should mark them out of use, but some small defects do creep through).

Windows disk check recognizes the error and tries to move the data to a good location and then takes the sector out of service by marking it bad. They might disappear with a clean and format, but you really don't want to prolong the failure.

I recommend that you backup your data now, before a more intensive recovery (if possible after failure) is required.

YES to a new HDD - SSD if your budget allows.

CrystalDiskInfo can be safely downloaded directly from the developer at CrystalDiskInfo - Software - Crystal Dew World.

With Thanks

Thank you to all who replied. I did a factory restore with the existing hard drive and then ran Scandisk again. This showed that the number of bad sectors had increased so I decided replacement was the way to go. Crystaldisk Info also indicated there were issues.

Replaced the 1TB drive with a WD 500GB drive as don't need all that space. Tried using the HP Restore Discs and they refused to work! Scoured the HP forums and found that this is apparently not uncommon when you replace a HDD with one of a smaller size (wish I'd known that before now!). One contributor had found a solution which was to clone the recovery partition from the old HDD onto the new one and then use the system restore option during bootup.

After a few lessons from youtube and some free software, I managed to create a partition on a USB HDD and clone the recovery partition onto it. I the plugged in the new drive, cloned the partition onto it and to my complete delight, the recovery option worked :-)

All up and running again - thanks for your advice

Glad you worked through the final solution and that you have a reliable drive.
