| 1287791 | 2012-07-11 07:58:00 | Hi. i can't defragment the main drive on my computer. there are two drives on this PC, one is Drive D, one is Drive c, Drive C is the drive that has 95% of the OS on it. It only has 20GB. I can defragment Drive D alright, C is not working and it doesn't do other checks properly either. What should i do:( |

| 1287793 | 2012-07-11 08:36:00 | The reason I would think that you can't defrag C: is because there is not enough free space to move files around as the defrag works. | Bryan (147) | ||
| 1287794 | 2012-07-11 08:50:00 | Use something like ccleaner (www.piriform.com) and remove the temp files etc. Then try again | Speedy Gonzales (78) | ||
| 1287795 | 2012-07-11 09:08:00 | Aso, try Defraggler (Also by Piriform, the same people who make CCleaner) which works well while the OS is running / writing to the drive. | Chilling_Silence (9) | ||
| 1287796 | 2012-07-11 23:25:00 | Smart Defrag from I/Obits is good too! | SolMiester (139) | ||
| 1287797 | 2012-07-11 23:30:00 | Also run DiskCleanup to get rid of all but the last system restore snapshot (if SR is used). That can get a few GB back. | Renegade (16270) | ||
| 1287798 | 2012-07-11 23:42:00 | My advice is dont defrag, seriously. Modern HD's with NTFS dont really need defrags old HD's: you run the very real risk of moving data into faulty parts of the HD. Ive seen that happen. Data loss !!! |

| 1287799 | 2012-07-12 00:31:00 | In my opinion defragging is good housekeeping on any hard drive and helps keep the data on your drive and the drive in good condition. Modern drives do require defragging especially if the system has insufficient physical memory. One of the jobs of defragging is error checking which will hopefully detect any potentially failing sectors and mark them as bad so data can not be wrote on those areas. By not defragging (and/or error checking) you are more likely to get data corruption from the drive continuing to write to bad sectors if it has any. If you have an older drive that has bad sectors, replace it asap as it will only get worse which can result in total drive failure and/or total data loss. If you cant defrag a drive, it is commonly for 2 reasons, as already mentioned, lack of disk space to perform the job (I think it is a minimum of 15% free space required), the other is disk errors. If you have enough drive space, run an error check on your drive and fix any errors - you may already have some corruption which can be fixed if caught in time. Sorry 1101, but I think telling someone not to defrag is not good advice. |

| 1287800 | 2012-07-12 00:41:00 | Don't defragment a solid-state drive. Just don't. But if it's a mechanical drive, yes, it will help performance, albeit marginally in most cases. Windows disk defrag, as iantech said, requires 15% free space to work effectively. This is approximate, and the exact amount varies depending on the size of the files & fragments moved, but it's a good rule of thumb. When you say it is "not working" what exactly happens - an errors message or something? | inphinity (7274) | ||
