PC/Computer gives a Blue Screen of Death (BSOD, tracked down to the hard disk drive by using chkdsk, which said that the C: drive was in the RAW format and the disk could not be checked

PROBLEM: My desktop computer with a new 1TB hard disk drive and is running Windows XP Professional, The C: drive containing Windows is 100GB and the rest of the disk is partitioned as drive D: which is used for storage. Both partitions are formatted to use the NTFS file system. The PC was running just fine until it produced a Blue Screen of Death (BSOD) yesterday. The drive’s power and data cables are connected correctly, but when I ran the Windows chkdsk diagnostic utility by entering cmd in the Start => Run box and entering chkdsk c:/r at the Command Prompt, it told me the C: drive partition was in the RAW format and the disk couldn’t be checked. When I entered diskmgmt.msc to bring up Disk Management, it confirmed the C: drive was unformatted. I then restored a system image created with Windows 7’s Backup & Restore, but got another BSOD today.

ANSWER: This looks to me as if it is a problem with software-related rather than a hardware-related problem. For example, if you use disk or file encryption software it could be responsible. You need to run the Windows chkdsk disk-checking program to give the drive itself a clean bill of health. Then you need to be able to find out which software is the cause of the problem. Note that chkdsk is available from Windows XP to Windows 8.1.

CHKDSK – http://en.wikipedia.org/wiki/CHKDSK

In Windows XP, open My Computer, right-click on the C: drive, click Properties and open the Tools tab. Click on the Check Now button. Place a check mark in both boxes with the mouse and click Start. Answer Yes to schedule the disk check for the next boot up and restart the computer. Note that the disk-checking can take several hours.

In Windows Vista and Windows 7/8.1, you have to run the Command Prompt as the Administrator. If you just enter cmd in the Search… box and then enter chkdsk (plus any of its switches) at the Command Prompt, a message that says: “Access Denied as you do not have sufficient privileges. You have to invoke this utility running in elevated mode”.

To do that in Windows 7 SP1 open Start => All Programs => Accessories, right-click on Command Prompt and click on “Run as administrator”. Enter chkdsk /? to be provided with a list of the available switches provided by the chkdsk command.
