    I have 3 computers on my network. I can transfer large files on 2 computers with no problems. One computer has XP pro and the other has Win 2000. On the 3rd computer I have Win 98. When I try to transfer a large file, say 800MB the system locks up. This computer has a 550 mhz amd prossesor and 256 mb of memory. I'm running a DSL router and can download large files through the internet but not through my network on this win98 computer! Any suggestions? Thanks :confused:

    I assume you mean that the 98 PC is the one that is locking up?

    Does it do this when transferring to or from it?

    If when transferring to it, it may be lack of disk space, other apps or processes using network bandwidth already, or it may just be that it is taking a very long time to get to the "preparing to copy file" dialog box as the files are so big.

    What are the symptoms that make you think that it has locked up? Assuming that you have a 100 Mbit network, in theory it would take 64 seconds to transfer an 800 Mbyte file across it if the network had no other traffic on it. In practise no network ever sustains 100Mbits for that long, and control bits and other checks increase the amount of data transferred so I would expect it to take between 4 - 6 minutes plus to copy the file. If either of your other machines are on the network at the same time that could easily expand to between 20 and 30 mins to copy a file that big over the network.

    If you've only got a 10Mbit network then obviously multiply everything by 10.

    I get to about 1min. of coping then it freezes and I can't even ctrl alt delete. I have to power off completly, and yes, I mean the computer with win98. I have 2 other computers that I can copy a 4 gig file with no problems. One computer has win2k OS and the other has xp pro. On the win98 computer I tried removing the protocals and installing but the same problem occurs. Help! Thanks.

    I merged your response to the original thread. You have to be patient. This is an all volunteer board and sometimes people are busy doing other things with their families or their personal lives.

    OK, maybe a long shot, but perhaps worth checking out ...

    Have you run scandisk on your drive recently? If your drive has errors (either hard or soft), it's possible that a large transfer will run into those problems and be unable to complete. OK, it's not a high-tech solution, but maybe it's worth a try.

    It's also possible it's a hardware problem. I'd check memory, IDE cables/sockets and DMA settings for starters.

    Hope this helps.

    Here are a few things to try:

    1) When I'm transferring large files, sometimes it seems good old DOS is better than Windows Explorer through the GUI. Try copying from a command promt. You can use "xcopy" with the /c switch to attempt a graceful exit if something goes wrong in the process. Typing a /? after "xcopy" will get you the full command line help for that program.

    2) Also check that the file name is not outrageously long or the file is not burried deep in a directory path. The Win9x network redirector has trouble with these.

    3) Nick sort of mentioned this and it is a good point. Any automated processes like screen savers that might hit the 98 machine during the copy should be turned off.

    4) Also check that any energy saving features such as spooling down the hard drives after x minutes of inactivity are set to keep the hard drive always on. The long copy may exceede this time limit and it is going based on the last keyboard input.

    5) Codejockey's suggestion about scandisk is a good one and I'd add that defragging the drive might help. Win98 fat32 or fat16 drives can get heavily fragmented and trash a really big file copy if the big file is being fragmented where it lands.

    As Davey said, be patient. We'll help you.

    I'll piggyback a coupla little things:

    Assuming you've several gigs empty space...& lots of ram(try lowering agp aperture size in bios if you don't have lots of ram)....there should be no(or at least a large max) limit on your TIF & pagefile settings. You might also delete pagefile and reboot-- windows will recreate empty one on boot. Re TIF, there's a delindex app floating around the web that will delete the index.dat files-- can be quite helpful...then I'd clean out all your TIF, temp, tmp, cache folders with ccleaner.

    It may help to ensure hard disk is primary w/ no slaves....

    Enable DMA & 32 bit access UNLESS if your system is old- pre 2000...this can be done for both with free version of x-setup + i think i remember in run/msconfig for the former... the latter in Device Mangler/your hard disk model/properties, and you must have this MS update: http://download.microsoft.com/download/win98SE/Update/5638-6151/W98/EN-US/243450USA8.EXE

    In one if the tabs of Control Panel/System there are a couple of settings re read-ahead & write-behind caching....toggle the latter & watch for effect. Re the former, there are a coupla very good reg files with optimized settings for all that based on your system config: http://www.mdgx.com/newtip16.htm#MCS http://www.mdgx.com/newtip18.htm http://www.mdgx.com/newtip6.htm#CDMAX

    Here are a few items that remove win98 limitations re copying large files, lots of ram, large hard disk sizes + associated format/fdisk/defrag/scandisk issues: http://www.upload2.net/page/download/PvBN9k7QppFCfgC/COPY2GB_4102222.ZIP.html (that particular copy2gb: 'only' for win98 SE version!!!!) Become msfn member and download 410222 version of the new esdi driver: http://www.msfn.org/board/Enable48BitLBA_Break_137Gb_barrier_t78592.html&st=0 http://www.mdgx.com/files/SCANFRAG.EXE http://www.mdgx.com/files/FDSKFRMT.EXE
    The ram workaround can be accomplished by installing unofficial win98 service pack2: http://exuberant.ms11.net/98sesp During install it will apply settings based on your ram amount.

    Good luck.
