NTFS - CHKDSK - Corrupt Files - Large Drives
To start, I apologize that this inquiry is extremely long.
Basic configuration: OS: XP Pro, Version 5.1.2600, SP2, Build 2600 Processor: Pentium 4, 2.5 GHz Bios: Phoenix Technologies, 6,00 PG, v2.2 File System: NTFS Ram: 1 G, available: 596 MB Virtual Memory: 2 G, Available 1.96 G Page File Space 2.41 G Storage: C: WD 100 G E/F: WD 200 G, partitioned in two (100 G each) G/H: WD 200 G, partitioned in two (100 G each) E/F, GH operating on separate controller Other Drives: D: HP 200I DVD/CD writer I: virtual DVD/CD (Daemon Tools) TSR: Norton System 2004 DiskKeeper 8 Zone Alarm 5.0.590.043 Webroot Spy Sweeper Other: Enabled 48-bit logical Block Addressing Support of ATAPI Disk Drives (KB 303013) I have run this configuration for about a year without problems. I work with large (min 800 M to up to 2 G) video files and edit many. Primary video players include MS Media Player 10.00.00.3646, Core Media Player v 4.0 Final build 449, and DivX Player 2.6 with 5.21 Codec. Recent reinstalls and updates to DivX have resulted in some strange anomalies in 3rd party editing software, particularly VDub which lists two identical DivX codecs (Divx.dll and divx.dll). With DiskKeeper running, periodically the system will advise that DK cannot defrag as CHKDSK is schedule for one or more of the auxiliary drives/partitions, primarily F, G, or H drives. E has not been affected as I can recall, nor does this occur to the primary and system drive C. Invariably if a CHKDSK occurs at boot up or if I manually execute CHKDSK from the cmd line (CHKDSK X: /f) , the files are rearranged and/or split such that continuous video files are no longer continuous or usable. Additionally many data files are reduced to 0 bytes. After another CHKDSK 'event' a comparison of the current data against the backup data revealed some interesting things: A couple files were reduced to 0 bytes., but the more interesting is several files were changed in size, usually upwards from the backup data. A property inquiry on the compared files indicated the file size matched, but the size on disk was larger and did not match, thus the disk file had been altered from the backup data. Other files have identical file size with disk size, but lists the creation date for example in March 2005, and a modified date of November 2004. And one more example, now that I am paying more attention: I had restored the data from the optical storage discs, evaluated most of the files, fixed some and concluded that they were for the most part intact, that I could discern. Looking to backup the files again to another partition, I discovered that the Recycle Bin on H and become corrupt. Performing a CHKDSK H /f from the command line resulted in 304 empty files (0 bytes). Thus I reformatted H since the basic data was elsewhere. I made another copy of the two directories on F to the clean partition H and backed-up the directories to the optical device. (DVD+RW disc and CD-RW). As an aside I could not do a 'long' reformat of H, only a quick format. Attempting the former resulted in only about half the volume available. The resultant properties for all this is as follows: F Partition: (Local Disk) Used Space: 4,847,411,200 bytes 4.51 GB Free Space: 95,171,960,832 bytes 88.6 GB \F Directory 1: Size: 2.62 GB (2,823,885,057 bytes) Size on disk: 2.64 GB (2,836,533,248 bytes) Contains: 5,636 Files, 1,081 Folders \F Directory 2: Size: 171 MB (179,964,802 bytes) Size on disk: 177 MB (185,638,912 bytes) Contains: 2,756 Files, 431 Folders \D Directory 1: Size: 2.62 GB (2,823,885,057 bytes) (DVD+RW) Size on disk: 2.63 GB (2,829,873,162 bytes) Contains: 5,636 Files, 1,081 Folders \D Directory 2: Size: 171 MB (179,964,802 bytes) (CD-RW) Size on disk: 174 MB (182,755,328 bytes) Contains: 2,756 Files, 431 Folders \H Partition: (Local Disk) Used Space: 3,104,825,,344 bytes 2.89 GB Free Space: 96,914,546,688 bytes 90.2 GB \F Directory 1: Size: 2.62 GB (2,823,885,057 bytes) Size on disk: 2.64 GB (2,836,533,248 bytes) Contains: 5,636 Files, 1,081 Folders \F Directory 2: Size: 171 MB (179,964,802 bytes) Size on disk: 177 MB (185,638,912 bytes) Contains: 2,756 Files, 431 Folders Directories 1 and 2 match exactly from F to H, although the F partition is considerably larger than the H partition. Investigation of additional files on F including system files, resulted in an additional 85 K accounted for on F. Any suggestions for this anomaly? My suspicions initially were a registry problem. In attempts to activate a restore point, resulted in failure. The system refused to restore any point and even when I cleared the restore history and created a new restore point, I could not restore that point several days later. I have attempted to employ third party registry cleaning software, (in retrospect not necessarily a safe option) but that does not seem to prevent the sporadic CHKDSK launch. Linking the DiskKeeper activity with the CHKDSK launch, I consulted with Executive Software and they assured me there was no conflict with their product and Win XP and SP2. I have attempted to read the posts in this group and have gleaned and executed the following: Checked the drives with the manufacturer's diagnostic softwa passed Preformed memory diagnostics with DocMemory Pro: passed Verified the system files with SFC /SCANNOW from the command line. Verified the Registry listings for autocheck to be "autocheck autochk*" (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Session Manager Are there any suggestions for resolving this problem before I initiate an OS repair or at worst a clean reinstall? |
