DOCUMENT:Q109251 18-NOV-1999 [msdos] TITLE :Cannot Remount DoubleSpace Drive (ASPIDRVR.SYS and DOSOAD.SYS) PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.2,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 6.2, 6.22 ------------------------------------------------------------------------------- This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames. SYMPTOMS ======== Under some Bernoulli configurations, DoubleSpace-compressed drive C may spontaneously unmount. Although the DoubleSpace-compressed drive is unmounted, the compressed drive and host drive letters are still accessible, with both drives showing the files on the host drive. Trying to mount drive C causes DoubleSpace to report it is already mounted that drive. CAUSE ===== This problem occurs when you use the Bernoulli DOSOAD.SYS device driver and have a SCSI host adapter that requires an ASPI device driver. MORE INFORMATION ================ For more information on using DoubleSpace, a ASPI device driver, and Iomega DOSOAD.SYS device driver, contact Iomega.
