Despite anecdotal reports of serious bugs in Microsoft Corp’s new MS-DOS 6.0, PC Week Labs says it has been unable to reproduce in a controlled laboratory environment any of the data-threatening errors specifically attributed to MS-DOS 6.0 or its DoubleSpace component, adding that it believes that many of the reported data-destroying errors can be attributed to the sudden introduction of SMARTDRV, the MS-DOS and Windows cache program, onto previously uncached systems – SMARTDRV caches disk writes, and any sudden power-down can cause unrecoverable file and disk errors – but be that as it may, Microsoft is taking the reports of data loss sufficiently seriously that it has pledged to do whatever it takes to track down and purge any serious flaws, although it has found none, and InfoWorld reported it found several problems, including one in the DoubleSpace data compression – but Microsoft said two of its engineers looked into but could not replicate the problems InfoWorld saw.
