Performing a select statement on a database that exists on a CD-ROM disc may return the following error:

Error: 601, Severity: 12, State: 2
Could not continue scan with NOLOCK due to data movement.


This problem is caused by a known bug in Windows NT 4.0.


Share the CD-ROM drive, map a drive letter to that shared drive, and read the data from the mapped drive instead of directly reading it from the CD-ROM drive.

Note that if you share the CD-ROM drive and then connect to this share, you will really be accessing the data on the drive through a normal file system driver (FAT or NTFS) rather than directly to CDFS. Since the problem only exists when trying to do READFILESCATTER on a CDFS file system, this option is a viable workaround.


For further information regarding this problem, including instructions on obtaining a hotfix, see the following Knowledge Base article:
