I have no problem accessing any files in my main disk 0 partition, however, I have not been able to run disk defrag in months, it says it cannot start, however, it can work perfectly on any drive but my HDD disk drive 0. And I have recently, within the past day, deleted the EISA partition, worth 6 GB, to free up space. Now I can create a new partition out of it. However, it will not allow me to format this new partition in either FAT32 nor NTFS. It simply gives me the error of it cannot format it. It leaves the partition as the RAW format. I would like to know would could cause this...1 person needs an answerI do too

Hello NovaCrazy,1. What is the exact error message you get when you try to run Disk Fragment on your computer?2. What is the exact error message you get when you try to format the other drive?For both your issues, I suggest that you run CHKDSK to check if there are bad sectors on your hard disk:This scan attempts to find and repair any developed bad sectors in the data available on the hard disk, and it can take much longer to complete.a. Click on start.b. Type cmd in search bar.c. Right click on the cmd and select the option Run as administrator. Type the following command, and press Enter:chkdsk [drive:] [/p] | [/r][drive:] Specifies the drive to check, this is the drive letter for your external hard disk./p Check even if the drive is not flagged dirty, bad./r Locates bad sectors and recovers readable information (implies /p).d. Press Y on the keyboard when you are prompted to check the disk the next time that the system restarts.e. Close all applications, and then restart the computer.Note: During the restart process, Windows checks the disk for errors, and then Windows starts.f. After the computer restarts, repeat steps a through d for the other volume by replacing with the drive letter on which you are trying to format.Note: I suggest that you backup all the important data on your computer before running CHKDSK as it could cause data loss in the event of failure.Thanks,Irfan H, Microsoft Answers Support Engineer.
