Re: [SURVPC] Disk compression trivia
Hi, Here's the end of your basically accurate DOS and Disk Compression story. When MS settled their suit with Stac Electronics and payed them something like at least 114 million dollars, they released MS-DOS 6.22 with DriveSpace which contained some of the Stacker algorithm but was not a copy or clone of Stacker. A modified DriveSpace came with the DOS 7.X component in Windows 95. Novell released Novell DOS 7.0 with a subset of Stacker version 3.0 which came to Caldera and stayed in OpenDOS 7.0, 7.01 and 7.02 and also in DR-DOS 7.02. IBM actually had the SuperStor disk compression in PC-DOS 6.1 as well as in PC-DOS 6.3. PC-DOS 7.00 has a full implementation of Stacker 4.0 for DOS and Windows 3.X included in the package, not a subset of functions. Having not seen PC-DOS 2000, I don't know what it contains, but would be willing to guess that it might still have Stacker 4.0, maybe with some updates. One would hope that such updates might include ability to recognize and display and deal with long filenames. PTS-DOS 6.70 has its own disk compression and file compression software written by the program's Russian developers.

Perhaps when Microsoft adjusted those utilities from their original forms, they didn't get a perfect fit. DRDOS 7.02 is far more stable and internally consistant on my machines. Although I can't speak from personal experience, I have heard the same about PC DOS. My experience has been mixed. I have been using MS-DOS 6+ on several machines and interlinking them. One day I decided to install DR-DOS 7.02 on one machine. Still having a need to have the machines talk to each other, I put intersvr.exe on the DR machine. Going back to the client (MS) I proceeded to connect to the DR machine. That went fine until I discovered that the more I accessed the machine, the more the FAT got thrashed. Before I could catch it, the whole drive was a gonner. So . . . who do I blame?

You are wrong, but you could still be right. I've got PC-DOS 6.1 here, and it came with SuperStore/DS! No coupons, it came included on the original install disks. This is the Norwegian version though, so you could be right as far as the US version goes. If my notes are correct the US/English version of PC-DOS 6.1 first came out in June 1993, and version 6.3 followed in November same year, while Norwegian ver. 6.1 have file dates of 19 November 93. In other words; the Norwegian ver. 6.1 was released about the same time the new US ver. 6.3, which could explain why SuperStore/DS came included with the Norwegian 6.1 but (maybe) not the US 6.1. As I understand it, at the time when Microsoft was telling the world that DoubleSpace compression was "integrated" and "built into" MS-DOS 6, they were also telling IBM that DoubleSpace was a competely separate product from MS-DOS 6, and therefore not included in IBM's license of Microsoft DOS source. DoubleSpace doublethink! Doublethink and doublespeak doubles the moneyg (Web browser parallels left as an exercise for the student.) Good point! To bIE or not to bIE, that's the question! Btw: I never used SuperStore/DS. Purchased Stacker 4.0 instead (w/upgrade 4.1 for WfW 32BFA support). Never experienced a problem with it, no data loss at all, runs smoothly, maybe since I perform weekly check and de-fragmentation, and monthly full re-compression. Found a rebuild utility on Stac's site. Never used it. Assume it works something like fdisk /mbr. To the original question that triggered this thread, don't know if it will also rebuild a Dblspaced vol file. Only one way to find out I guess.

Re: [SURVPC] Disk compression trivia
Does any one know how to format a flopy disk whith ms dos 622 or higher so that drvspace.bin wont automatically be included in the system transfer? As well as be loaded, wheather you use it or not. removing it afterwards shouldn't make a problem occour. you could also try: format a: sys c: a: will that copy the doublespace file to the floppy? Oh, yah, what about pressing control C when the press any key to run scandisk comes up? Interesting idea, but I would have to do it again the next time the PC starts wouldnt I? Also if I turn the PC on and go do something else in the mean time (ex. answering the phone, searching CDs etc.) scandisk will start after a time interval (30 sec?) I find this very strange and really annoying since I can't leave the PC when it boots W95. Now there isn't ay problems with this anymore since I only get an error stating that I need M$-DOS 6 to run D:\Dod\ScanDisk.Exe since it still can find it in my path. Another boring thing is if I leave my modem on and reboot and start Windows, then it tries to "install it". (I thought I did that when I plugged it in?) I'll add the line autoscan=0 to msdos.sys later (when I feel an urge to see the Star Wars trailer) BTW: All of you that don't have W95 (with QuickTime 3) and want to see something from the trailer for Episode I: "The Phantom Menace" can visit my homepage I put some images up there (28 to be exact).

COMMAND.COM was hacked to display a slightly different version number. (Lie, that is.) Otherwise, 6.21 was exactly the same as 6.20. If you have MS-DOS 6.21, you *can* run the 6.20 version of DoubleSpace simply by coping the files from another machine. like Open/DR-DOS has. As an aside, did DR DOS 6 have Stacker, or was it introduced with Novell DOS? I seem to recall DR advertising DR DOS 5 - or maybe 6 - as having 'UltraStor' or something similar technology, not Stacker. SuperStor, by AddStor Inc. An earlier version of the same product in IBM DOS 6.3. DR DOS 6 also included Multisoft's Super PC-Kwik disk cache. If nothing else, Novell's purchase corrected a lot of misspellings!

Perhaps what you state about sartdrive is the reason I've never used it? I heard that it wasn't good and i had never heard of it, so I removed it from my autoexec.bat and it has never found it's way back unless I test it for some reason (namely Arachne speed comparsions) Best cure for my PC? Del scandisk.exe :) Deltree/y windows is also a good way to fix most of your PC troubles. //Bernie To unsubscribe from SURVPC send a message to [EMAIL PROTECTED] with unsubscribe SURVPC in the body of the message.
