I have probems to install an additional 3,5 inch 720K disk drive to IBM compatible PC. My computer is Tandon XT with 5,25 inch 360K disk drive (A) and 20M hard disk (C). Operating system is MS-DOS 3.2 and new drive is Epson SMD-300. After I was put the new drive to its place and checked cables I added to config.sys file line DRIVPARM=/D:1 /F:2 which should configure new drive as drive B and 720K. I rebooted my PC and tried to read a formatted diskette in driv B, but then camed only following error message "write protection error" and the same text from drive A. Only drive C was OK. Then booted again from drive A with MS-DOS 3.3 and the line in config.sys file was DEVICE=DRIVER.SYS /D:1. This time I got a diectory list from drive A, but when I tried to write to A the machine wrote to diskette in drive B, but it didn't understand drive B. I would be pleased if anybody can tell is wrong with these configurations or is the drive broken or something. Pekka Riiali riiali@kannel.lut.fi

When I was considering a 720K drive there were postings about a weird bug in DRIVPARM. Basically, the options need to be prefaced with three ctrl-A characters, for some unknown reason. I tried that right off, and the following line works fine for me: drivparm=^A^A^A/d:1 /f:2 /h:2 where `^A' is the single character ctrl-A, or 0x01. I never tried the documented form, so I don't even know what problems might have occurred. How anybody ever thought to insert ctrl-A's is beyond me...
