DoubleSpace Doesn't Mount After Installing RAMDrive (96440)


The information in this article applies to:

  • Microsoft MS-DOS operating system 6.0
  • Microsoft MS-DOS operating system 6.2
  • Microsoft MS-DOS operating system 6.22
This article was previously published under Q96440
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

If you use DoubleSpace with a removable hard drive (such as Syquest, Bernoulli, or Quatam Passport XL) and later install RAMDrive, DoubleSpace may refuse to mount its compressed drive(s).

CAUSE

This problem only occurs if the RAMDrive DEVICE command in the CONFIG.SYS file precedes the removable hard drive DEVICE command line. Since RAMDrive may inadvertently use the drive letter of the removable drive, DoubleSpace may not find the compressed volume on the expected drive. The same behavior may occur if you remove RAMDrive after compressing your removable hard drive. (The drive letters shift and DoubleSpace does not mount.)

WORKAROUND

If this problem was caused by installing RAMDrive, you can simply move the RAMDrive DEVICE command past the removable drive's DEVICE command in the CONFIG.SYS file. The advantage of this workaround is that the drive letter assignments stay the same.

If this problem occurs after removing RAMDrive, run DBLSPACE. From the Drive menu, choose Mount. DoubleSpace scans all your drives for compressed volumes and reassigns drive letters appropriately. This workaround may cause problems for programs configured to specific drive letters.
