Dear Netters: I just upgraded my hard disk drive to a Corner 120MB. But it seems to me there is something wrong with it. The pkunzip program simply refuse to unpack becasue it says hard disk is full, while the chkdsk says lots of disk space still available. The zip file passed CRC checking on the floppy but after I copied them to the hard disk, it fails CRC checking. (I tried both xcopy and copy command). I have never met these situations before, do you know what's the reason ? (The Macfee's antivirus scan doesn't find anything wrong. ) My dealer says maybe the pkunzip file messed up the HD's FAT table. Also another odd thing is that the various commands that I put in the autoexec.bat file like DOS PATH sometimes works, sometimes doesn't work. It's very unstable. The system get halted if I set the comspec=c:\dos\command.com, but this is exactly the same command.com as in the root directory. Anyone knows what's happening here? Regards, Xiaojun.

Hi, Netters: Since I didn't receive any reply with respect to my original posting, so I suspect that maybe a FAQ, but unfortunately, it's not. The disk full problem is not the case because I have lots of tiny files in my root directory. Is there anyone out there who is kind enough to answer my question, because I want to make sure that I didn't get a bad harddisk while my dealer says it's ok. Following is my original posting: >>Dear Netters: >> I just upgraded my hard disk drive to a Corner 120MB. But it seems to me >>there is something wrong with it.

Dear Netters: Since I posted my message, I received lots of replies and suggestions. It's so kind of you. First of all, my problem was NOT the case that I have lots of tiny files in my root dir. Here was my reply to Ken yesterday: >>This was not my problem at all. My root directory contains only >>autoexec.bat , config.sys and two hidden files >>i.e. io.com and msdos.com. >> >>Other files are NOT in the ROOT directories. Secondly, my hard disk is divided into 4 parts, each 30MB, so it's not caused by the wrong partition. Thirdly, according to my description, the dealer was finally convinced that there is something wrong, because after using (xcopy) copy command, and do the comp, it reports compare error at offset ..., and no EOF stuff, they said maybe DMA is bad, I don't know what's DMA is. Anyway, as long as they believe there is something wrong, it's fine. I am so frustrated because they have kept me bringing my machine back and forth for more than 5 times in one week and keep saying the machine is fine. Sounds like I have done something wrong. Finally, since it's an odd phenomenon, if anybody is interested in the final result to my harddisk drive, I will send him/her a report. Thanks again for all your replies. Regards, Xiaojun. P.S. I am sorry if I made a wrong choice to do the posting in this news group, but I don't know what's going wrong in the very begining, I just want to make sure the problem is not caused by pkunzip. and I still post this here because lots of you have already replied my message and I can't reply all of you individually, many thanks.

DOS has a maximum number of directory entries allowed (I don't know the exact number, but I seem to remember something like in the 120's). If the number of files exceeds this number, then DOS will report the disk as full, even if you have many Mbytes free. Try creating a directory and moving all of the tiny files there and removing them from root. As far as the root directory is concerned, a subdirectory is only one file, even if it contains a million tiny files, so a general rule of thumb is to keep as few files as possible in the root, and place the rest in subdirectories. Hope this helps your PKUNZIP problem, as far as the command.com problem is concerned, I beleive DOS likes to find in in the root directory only, and sometimes causes problems if its rold to look elsewhere for it, but I am not sure of that, since I always keep command.com in the root directory.

When you say " lots of tiny files in my roo directory.", do you mean in the hundreds? If so, then you might be running into the limit for files in the root directory. If that is the case, all you need to do is to start making subdirs, and moving files there. The maximum number in my root dir is 512, but may be different for other HD's. Good luck, Rob 6600m00n@ucsbuxa.
