Somebody :) made an experiment with his old 486 600MB floppydrive and HD. Experiment went the following way : copy c:\command.com a:\ And now the HD is lost (a:\dir gives same result as c:\dir) This someone now gets the message that size of c: is exactly 1.44 MB . :) Could somebody please tell me how to access HD. No OS in HD.
did you run the subst command or something, i will assume you have rebooted your computer, since you copied the files. if you have a boot disk (or any dos disk 1) boot off of it, and type fdisk see if it reports a harddrive, goto info, and see how much space it has, and what its formated to.

Only command (ok it was me) i made was copy c:\command.sys a:\ I tried with W95, w98, DOS6.22 bootdisks and none of them gives access to HD. Tried FDISK and result is that fdisk reads only floppydrive. And yes computer is rebooted. Tried also format c: /s and got message "wrong version of MS-DOS". Tried also installing DOS622 -> ...aborted cause DOS already exists which isn`t true. HD was formatted just before the copy command.
check the bios to see if it has a harddrive listed, if it has autodetect, let it detect your drive(s) again. also if this is a newer computer, in the bios there is usually a switch called, reset data configuration, choose yes, reboot (for both), and see if anything changes

Perhaps someone should add that that command "copy c:\command.com a:\" shouldn't cause any harm to your hard drive at all, not even touch it. It could, though, make a boot diskette bootable. Your problem has probably nothing to do with you typing that command, but something else that's messed up in your computer. It could happen if the hard drive is broken (you have gotten a light head crash) and in that case, I would try to run scandisk a couple of times on it before I put anything important on it.

I have gotten into trouble by entering MOVE COMMAND.COM A:, but never by copying it to A:. Your problem could come from a lot of things, but my first guess would be that your CMOS battery went dead or momemtarily lost voltage at the time you encountered the problem. Old 486 computers seldom had auto detect so the hard drive perameters are not in the BIOS any longer. To fix this you go into the bios and select #47 USER in the hard drive section and enter the perameters (Heads, Cylinders and sectors) for the hard drive. If it is not this go on to other things involving a bad hard drive such as no power, ribbon cable off or a crashed drive.
Summary: can anyone help. I need an old colpy of command.com for a 286 toshiba t1000le laptop. Ive no idea how it got corrupted, but the system will not boot, and when i use a boot disk i have freom a win95 ma...
