Re: Error code 0x00000024 how
A problem occurred within NTFS.SYS, the driver file that allows the system to read and write to NTFS file system drives. There may be a physical problem with the disk, or an Interrupt Request Packet (IRP) may be corrupted. Other common causes include heavy hard drive fragmentation, heavy file I/O, problems with some types of drive-mirroring software, or some antivirus software. I suggest running ChkDsk or ScanDisk as a first step; then disable all file system filters such as virus scanners, firewall software, or backup utilities. Check the file properties of NTFS.SYS to ensure it matches the current OS or SP version. Update all disk, tape backup, CD-ROM, or removable device drivers to the most current versions.
As Dr.IP says, get your important stuff off your harddrive and store to a flash drive and/or burn to CD/DVD.
People can often access their harddrives if they Slave it in another PC. Often you can run a full harddrive diagnostics as a slave. Seriously look into getting a new harddrive.
