Corrections to Minor Problems for Better Handling Bad Sectors
SMARTDrive version 4.1 includes the following corrections:
• SMARTDrive now correctly deals with bad sectors.
• SMARTDrive now correctly handles the int 21 function 68h (Commit
File) carry flag.
SMARTDrive Now Supports DoubleSpace
If a DoubleSpace volume is mounted before SMARTDrive version 4.1 is
loaded, it caches the DoubleSpace host drives. This functionality is
similar to the way SMARTDrive versions 4.0 and 4.1 work with Stacker.
The caching of DoubleSpace through the host drive is accomplished
using a special interface to the DoubleSpace components.
If you specify a DoubleSpace drive on the SMARTDrive command line, you
get the following message:
To use SMARTDrive with DoubleSpace, you must specify the host drive.
If SMARTDrive is caching a DoubleSpace host drive, it lists
DoubleSpace drives with asterisks (*) to indicate that that caching is
really done via the host drive.
