Yes, I have an external drive case with an IDE CDRW (Samsung 52/24/52). The driver "DI1000DD.SYS" is only for Mass storage external disk. My problem is only when I boot on Dos (Win 98). It is recognized if I stop feeding and supply to reset the external case for recognized by the driver "USBASPI.SYS" 2.06 of Panasonic.

I would suggest to remove the CDROM drivers and try the DI1000DD driver instead, as you are not directly communicating with the CD drive you are communicating with the drive case No USB cd entries in autoexec.bat, but following in config.sys device=usbaspi.sys /v/w device=di1000dd.sys

Hi, After many tests, I have this constatation : For connecting only one External Usb 2 Case with Recorder (Not External Disk in dual) using a CardBus Pcmcia Usb 2. The only solution is : "config.sys" with : device=usbaspi.sys --> V 2.6 of Panasonic device =usbcd.sys /d:mscd001 "autoexec.bat" with : mscdex.exe /d:mscd001 Not use "di1000dd.sys" because for : External Disk by Usb 2 Case. But there is an uncertain detect of external recorder (see the other response for resetting the recorder case). The recorder is detected or not detected according to his humour !!!! Where can I sent this problem to the conceptor of this driver.

That's correct - use DI1000DD.SYS for mass storage devices (hard disk, flash drive, etc..) and USBCD.SYS for CD readers. Am sorry but I have difficulty with statement. Have problems understanding "... if I stop feeding and supply to reset the external case for recognized by the driver ..." Does this mean you have to reset the external drive by cycling its power OFF then ON? Let me see if I got this right - 1. You are NOT using /V and /W in USBASPI.SYS [ Can you try putting in these two options and report what comes out? Plug the drive in only after the /W option says so] 2. When you boot from DOS (created by Win98), it normally won't recognize the external CD-ROM [Does it time-out or does the system wait for you to reset the external drive by turning it OFF then ON?] 3. Are you resetting while it is waiting to detect the drive OR before starting to boot from DOS? Maybe you can try out this option on USBASPI.SYS (am not 100% certain of its use) device=usbaspi.sys /V /norst

This is the results of my test : 1/ The external recorder is on 2/ Boot Dos (Win 98) 3/ The Cd-Rom Device driver is not installed 4/ Boot Dos (Win 98) and when appears Win98 in the screen, put the switch of the external recorder off, then on. The external recorder "Samsung Cd-R/RW SW-252B" is detected and the Cd-Rom Device Driver installed. Remarks : 1/ I have test with switch device=usbaspi.sys /V / norst or /V /W 2/ In the manual of the CardBus it is indicated that there is a Dc Input Adapter (But Optional, so I don't have). Is-it a problem of feeding of the CardBus ? Thank you for a response.

Wierd problem. I assume you have no problems detecting the ext CD-RW on Windows (i.e. w/o the OFF-ON action) and this only happens in DOS? Also, your external drive has its own PS and is NOT stealing power from the USB bus. Here's how I would approach this: 1. Could it be driver compatibility? As there aren't too many Cardbus compatible USB drivers, the options are to 1.1 Try these options on USBASPI.SYS [To use slow down mode] device=usbaspi.sys /V /slow /norst OR [To force USB1.1 operation] device=usbaspi.sys /O /V /slow /norst 1.2 Try running the ext casing on another PC with on-board USB. 1.3 Try a casing with a different USB-IDE bridge chip or 1.4 Try a different Cardbus controller 2. Could it be the CD-R/W drive? 2.1 Try swapping a regular CD-ROM drive into your ext casing and see if it gets detected without the wierd behavior. 2.2 Or if under warranty, try swapping your external USB case as the IDE-USB bridge may be flaky or the power supply underpowered 2.3. Maybe it's an initialization/timing issue on the CD-R/W - is your Firmware upgraded to latest v. R701 for SW-252B (dangerous - try at your own risk!) 3. Could it be the CardBus controller? 3.1 Make sure you have disabled power saving features that affect your cardbus slots 3.2 Make sure your notebook/PC can supply enough power to the cardbus cards. Good luck!

Hi MaxmaxUSB, I have connected the external case usb 2 with Samsung Recorder 52/24/52 to an Adaptec Pci Card Usb 2 on my Desktop and with a unique electrical plug. The Firmware is at the last version : R701 (detected by Liveupdate after connection to Samsung Site) and I have the same diagnostic. I think that there is a problem of dialog between the external case and the Samsung Recorder. Thanks very much for your suggestions. Best Regards.

Hi, A precision: when the external recorder is recognized in boot dos (win 98), ghost 2003 works very well for restoring image. thanks!!!!
