Sorry to bring this up again. I know that this has already been discussed at length, but I seem to have discarded all the info. I am having problems with configuration of a 1.44 Meg floppy by TEAC. Here is the problem: I have just added a 3.5 inch 1.44 Meg floppy to my system (which has been functioning fine), and now when I use normal DOS utilities such as COPY, XCOPY or other utilities such as XTREE I consistently get an error message when accessing the 1.44 Meg floppy: Sector not found error reading drive F Abort, Retry, Fail? Chkdsk, Dir, Norton's NU and NDD and FastBack Plus all work fine and never complain. I have tried numerous variants in CONFIG.SYS with the same results. Currently, the CONFIG.SYS contains the following line: DEVICE=DRIVER.SYS /D:1 /T:80 /S:18 /H:2 /F:7 I have tried PC-DOS 3.30 and 4.01 and MS-DOS 3.30 all with the same results. I used the Advanced AT Diagnostics 2.01 to configure the system. Since it does not know anything about 3.5 inch floppies, I told it that the drive (physically drive B:) was a 1.2 Meg floppy. As of this posting i have the following configuration: AT compatible 6/10 MHz 1 Meg RAM Phoenix 3.10 BIOS WD 1006V-MM2 controller Seagate ST-251-4 1.2 Meg TEAC floppy PC-DOS 3.30 (same results with MS-DOS 3.30) I don't know where the problem lies: in SETUP, DRIVER, CONTROLLER, or BIOS (or a combination of the above). Any help will be appreciated.

Have had the same fun 'n games when I built my own AT clone. For me, it turned out that the sensor in the Toshiba drive I finally settled with cannot read the indent style 1.44 floppies (there is an indent, rather than a second window through the floppy; Memorex 2S/4D's are a fast example). When I finally purchased some of the double-windowed disks, the problem with Sector Not Found errors went away. It seems that most AT clone BIOS do not handle the 1.44 drives properly. I have set up a couple of Format batch files to handle the switches necessary when formatting for 720 3 1/2"s and 360k 5 1/4" in the high density drives. I do not use any drivers for the 3 1/2, just normal BIOS handlers. The motherboard/drive controller combo here is the AST Xformer 286 w/ 1 meg memory and the Western Digital WD1003-SR2 RLL/floppy. The AST diagnostics keep telling me the 3 1/2" drive is a 1.2meg, but the BIOS entry is for 1.44 meg. I just live with it and work around the dain-bramaged thing.

Just to add: certain programs will alter the environment when you shell out of them. Just had an attack of the "drive stupids" when I shelled out from my telecomm program. Warm restart cleared the brain drain, now it works fine. IBM Clone <> IBM. Even IBM <> IBM. There is no such thing as a 100% clone of IBM PC.
