Apologies if this isn't the correct forum but im having problems saving spreadsheets in excel. When saving to a specific folder on my hard drive I receive the error message "Data Error (Cyclic Redundancy)". It doesn't happen every time but most of the time. It only happens in Excel and only happens when saving to one specific folder. Does anyone have any ideas about the problem?

Thanks.

The hard drive has a bad sector under that folder?

Test the hard drive with the manufacturer-provided utililty to confirm.

The bad sectors can be marked unusable with the chkdsk utility to make Windows work around the bad areas, but you should consider repacing that drive.

I ended up fixing them with chkdsk /f.

Thanks for your help
