problem with defrag and write-protection

[Haan22]

Did search, but found no useful help. I've been trying to defrag my harddrive, but a lot of files aren't being processed. There aren't any information on why, but they are all write-protected, and when I try to remove the protection it reappears immediately. Any ideas?

Operating system?
Ran chkdsk or scandisk?
Examples of files? What types of files?
How do you know they are write-protected? What does the error message say?
How are you removing the protection?
Have you tried running it in safe-mode?

Have you checked the hard drive with the free diagnostics at the appropriate drive maker's site?

"Operating system?"
Win XP Pro

"Ran chkdsk or scandisk?"
Not yet

"Examples of files? What types of files?"
Fileshared manga and anime, jpg, png, wmv.

"How do you know they are write-protected? What does the error message say?"
The write-protection shows when checking the properties of the catalogues affected. The error message is just a statement that it couldn't defrag certain files and that I should check the report for details.

"How are you removing the protection?"
By unchecking the relevant catalogues and applying it to all files and sub-catalogues.

"Have you tried running it in safe-mode?"
Not yet.

No, since it doesn't appear to be a hardware malfunction. The files are readable and moveable.

this does not mean there are no errors within your OS. You need to run scandisk.

Done, no errors.

Btw, are there an upper limit to the size of the files that defrag can handle?

You could try DLoading and running DisKeeper Lite which is still free i believe...
