I started to prepare an external drive for backing up other drives.  I started CCleaner's disk clean and saw the time required go from 1 hour to 2 days.  I stopped it and went straight to defragging with the XP Disk Defragmenter.  It looks like that will take all day at the current rate.  Is there any advantage to doing the cleanup first?  


Also, would a cleanup AFTER defragging do any good on a drive that will be used only for data and backups?  


I've ignored my old XP SP3 Dell Dimension 8100 for too long and will be doing that next.  Is defragging quicker if you do it more often?

I would do the clean up first and the defrag last. There is no point in defragging a file if you are going to delete it. But thats just my opinion.

Clean it. empty your temp files ( use TFC )and recycle bin.
Copy or backup all work files, photos, email, etc., to another hard drive, CDROM, DVD or other type of media.

Use CHKDSK to scan and fix the drive first.

Thanks for the feedback, Nick.




Long time back I read that CHKDSK could cause problems.  I had an old Norton Disk Doctor installed that gave me the following advice:
            Norton Disk Doctor found problems with the file system.
            Run Norton Disk Doctor and check the Fix Errors option.
Is CHKDSK with XP-SP3 better than my Norton 2006 utilities?
That was an interesting read at your link to BP's defrag.  I recently had a backup fail which I blamed on my disk problems.  Could it have been the AV or Win Update programs interfering?
Thanks, also

I always do a virus scan first with Malwarebytes then clean with CCleaner then use File shredder then Smart Defrag.

Hi Chic Bowdrie -

Microsoft built several tools into your computer, and it sounds like you are using XP still, so use those tools and just add a bit of help from the trusted methods. chkdsk /r will never harm your system (throw that old Norton Disk Doctor in the bin)

I always do a virus scan first with Malwarebytes then clean with CCleaner then use File shredder then Smart Defrag.

If you mean IObit Smart Defrag, then you are wasting your time, as IObit programs and MBAM will always conflict.

Also you do a Malware Scan with MBAM, not a Virus scan << This is for your Antivirus program


It is just as simple to use Temp File Cleaner as per boopme and even Disk Cleanup, from System Tools, then run your Microsoft defrag program.
