To the USTOR team, Needless to say that I've spent the last year living with a slow and cumbersome system due to the "DOS compatibility" mode of Windows 95. Needless to say that I spent months searching the web and CompuServe for the latest Ultrastor 24F miniport driver, only to discover that the company was no longer in business. Needless to say that I could not use my $1000 DAT tape drive to backup my system because the 64/63 mapping mode was freaking out Windows 95. After finally finding your site - and browsing around for about 5 minutes - I found salvation! I followed your suggestion to change my mapping mode to 64/32 and reformat/reinstall windows. I would have never found this on my own. Of course - it worked! Now my system is humming (1.2 MB SCSI hard drive at 10MB/sec Sync) and my tape drive works fine. My only disappointment was that it took me so long to find your site. Thanks a Million! You guys are what the web is all about. Sincerely, Bob Begun Solus_Software@compuserve.com
