Hello,

I had a few problems with getting this drive going again, but I finally managed by cleaning the lens; thanks to those who suggested that. Now it works perfectly in DOS, using an Adaptec 1542C, aspi4dos.sys, and uni_asp.sys, a CorelScsi driver. However Win 95 is a different story; I seem to get random crashes, sometimes a fatal error, at other times it will just freeze and fill half the screen with symbols, or occasionally a single horizontal line near the top of the screen, which made me think it might be a display
problem.

I've tried disabling hardware acceleration and other settings on the card, and this seems to help as does running with a VGA driver, but it still crashes near the end of large backups. I've noticed that the throughput seems much higher than in DOS, so I also tried slowing the
disk down by using the troubleshooting settings on the "performance" tab. Again, disabling sync. buffer, and write cacheing also seems to help slightly, and finally, I've tried disabling sync transfers in the settings tab of the native win 95 driver. Icidentally, the crashes always result in a scrambled File system on the disk, with lost chains, crosslinked entries, etc.

Another, possibly related problem is that I have a Wangtek 5525 Tape drive that won't work on it's own in Win95 AND DOS, but will work when another SCSI device is in the chain. I'm sure that I've adjusted the terminations correctly in both instances; though the optical disk will work on its own, I still get the problems I mentioned above.

I have a Matrox Mystique, on a UM8810 board, latest bios with an AMD 5x86 and eide HD. The 7010 was manufactured in 92 and has the original bios

Anyone have any ideas? I've tried looking for drivers from Panasonic or Plasmon/Reflection, but have had no luck. Someone suggested an Optisys driver, but $495 is beyond my pocket.

Regards,

Joe Kirlew

Hi Joe: Maybe we can help you out with these problems, but let's try and single certain things out to keep this from becoming confusing. First things first, I'll take you through some things to check so that we can stabilize the system. When you receive errors, jot down as much as possible and post it here.

1. Visit the Matrox site and download the latest "Windows 95 *approved* driver", not necessarily the latest driver, and install it.

2. Go to Control Panel, click on the System Icon and click on the Performance Tab, then file system and change the typical role from Desktop to Server (if you haven't done this already), save that, then click on the Graphics Button and set the acceleration at about 1/4, and save that.

3. Next, reboot your system and go into the Bios/Cmos setup for your motherboard and look for any APM settings, advanced power management, and disable them entirely. Save the settings and boot through to Windows 95. In Windows 95, go to Control Panel and look for any APM settings there. If there are none, don't worry about it.

4. Next, go into the Control Panel, Display and check the settings for the video card and monitor. Make sure that the refresh rate setting matches the capabilities of your monitor. If they are set too high, you will get errors.

5. Next, using Wordpad or Notepad, look for a file on your drive called bootlog.txt. Check the last 10 or 15 lines and note any load failures. Some are normal, but others may tell us where the problem is. Using copy and paste, paste the last 10 or 15 lines here.

I'll wait for your next post!
Best regards,
Dennis

I'm afraid I've  already done all the above and a whole lot more, with no luck; all my bios settings are at the most conservative also. however I have had a look at bootlog.txt and as well as posting the last few lines I'm posting the 4 fails I found also.

[00019468] Loading Vxd = ndis2sup.vxd
[0001946A] LoadFailed  = ndis2sup.vxd

[0001948B] Loading Vxd = vshare
[0001948C] LoadFailed  = vshare

[00019498] Loading Vxd = vpowerd
[00019499] LoadFailed  = vpowerd

[000194D0] DEVICEINIT   = MTRR    
[000194D1] DEVICEINITFAILED    = MTRR    

LoadSuccess = user.exe
LoadStart = MSGSRV32.EXE
LoadSuccess = MSGSRV32.EXE
Init = Final USER
InitDone = Final USER
Init = Installable Drivers
InitDone = Installable Drivers
Init = TSRQuery
InitDone = TSRQuery

The "share" vxd is worrying, but seems to have loaded in another part

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Joe, the first three fails, ndis2sup.vxd, vshare and vpowerd, are all okay. Ndis2sup is for netware netwroking (if you don't have it don't worry about it), Windows attepts to load this automatically.
As for Vshare, if you look back, you will see this loaded once and Windows, after detecting different files may try loading it again, finds the first one and fails. Vpowerd is for power management support and it fails if windows doesn't find power management. Now, for MTRR, this is a virtual device driver loaded by or for DirectX 5. Has DirectX 5 been installed on this system? or any games requiring DirectX 5 compliant drivers?

Let me know!

Yes, it has, but this problem is unconnected as it happened when direct x 3 was loaded.

I've since reinstalled Win95 and I was pleased at first to see that the drive wasn't causing the system to lock up anymore, only to find the usual mess of cross linked files and invalid filenames after Itried writing to it. This ONLY happens in Windows 95, not in DOS, where it works fine. I've got a feeling that the throughput is too high(much higher than the 8MB/s I have aspi4dos set at under dos), but I can't find any switches to alter the speed in the Adaptec documentation. I'd be very interested to hear from anyone who's got one of these drives up and running under Windows 95.

Joe: Part of the problem may be that your trying to run the SCSI devices both in real Dos as well as under windows. You can run Dos from within Windows and access SCSI devices that way, but when you call real mode drivers from Dos (config.sys and autoexec.bat) and then call protected mode drivers from within Windows 95, the result is what you are experiencing. If your going to use this drive in Windows 95, you will have to disable the real mode drivers and then make sure the protected mode drivers are installed properly.

No, I can definitely rule that out. I've thought that the problem might have been an incompatibility between 32 bit and 16 bit file access or the long names might be a problem, so I've tried using cartridges exclusively under windows95. Its always the same; eventually the disk becomes unusable due to the problems above. In fact I can't even get it do one backup/compare of say 20MB without problems. However, If I use the same cartridges with the real mode drivers, exclusively under DOS, they're fine.

Well that lends quite a bit to the problem. Visit the Panasonic site or call them directly and request the latest 32-bit drivers for that drive. For the SCSI card, use only the Adaptec 32 bit drivers, and for the drive itself, use only the drivers recommended by Panasonic for it and try that. It sounds like the drivers are causing data corruption. BTW: Adaptec may also be able to help you, they have a good tech dept.
