A problem occured while I was using a SIMTEL program DESK130 (a desktop utility) while it was rearranging my 30Mb harddisk for better performance or whatever. The result was that my hard disk could not be rebooted. So I rebooted with my DOS 3.00 diskette from drivve A: The hard disk is formatted with 3.2. Now I cannot reboot the hard disk without formatting it seems, the Norton utilities report that the hard disk is fine in all repects, system files, FAT's etc. When I bring up the system under 3.0, I cannot format a diskette using my 3.2 utilities. A solution could be to check and write the system (3.2 preferably) on the hard disk again. Does anyone know how to write only the boot-stuff on disk without reformatting the hard disk? Or any other suggestions? I seem to have myself found in a catch-22 situation. Peter Teuben (i'm using this account from a friend, you can reply to him)

When I updated the system on my HP-Vectra (AT compatible) from 3.1 to 3.2 all I had to do was boot 3.2 from diskette and then transfer the system files with A> SYS C: After that all I had to do is transfer the new MSDOS files (using REPLACE). Before you reformat your hard disc you might want to try this first. Gary

Specifically, a PC-DOS SYS looks at the target disk and removes any existing IBMBIO.COM and IBMDOS.COM and writes the new ones from the source disk. An MS-DOS SYS will, of course be looking for IO.SYS and MSDOS.SYS. Some versions will not recognise the other, will not delete the existing system files and will report "No room on target disk". Solution: unhide the system files and get rid of them. I know Compaq PC-DOS 3.20 does not have this problem but Microsoft's MS-DOS 3.20 does. Other possible problems here: If the version of SYS does not re-write the boot sector (are there versions which do not?), then the disk will not boot as it's bootstrap program will be looking for the wrong files. Also, there must be enough continuous free space after the root directory for one or both system files as DOS may not allow them to be fragmented (this differed with DOS version...I forget exactly how). This reminds me of another stupid incompatibility in the BACKUP/RESTORE pgms. MS-DOS BACKUP writes the files pathname in the back-up file with "/" while PC-DOS's BACKUP uses "\". MS-DOS's RESTORE reads either way. PC-DOS's only recognises files with "\"s. Silly, eh? (I might have a few things reversed there as I'm going on memory, but it's something like that). Hope that wasn't all redundant.

There was an upgrade which fixed this (among other things), MS-DO v3.21. So, other than MS-DOS v3.20, all DOS versions use a "\" to store the full filename when backing it up. I've seen a program on some BBS which did nothing but read MS-DOS v3.20 backup files and replaced a "\" with a "/". (Note that MS-DOS v3.20's RESTORE utility did correctly read the files produced by the MS-DOS v3.20 BACKUP.) -Lee ________ 01001100 Lee Fisher, Microsoft Corp., Redmond, WA. 01000101 {uw-beaver,decvax,decwrl,trsvax,sun,attunix,uune:}!microsof!leefi 01000101 leefi@microsof.uucp 01000110 leefi@microsof.beaver.washington.edu 01001001 disclaimer: My opinions are my own, not those of my employer.
