CD-Driver noticed but drive invalid

I run a win95 and in MS-DOS it will not recognize my CD-ROM Drive (nor
has it eveer) i have added LOADdevice=C:\command\ibmidecd.sys
/d:ibmcd001 yadda yadda yadda... in my config.sys
and have added MSCDEX /D:ibmcd001 /l:H in my autoexec.bat
i know that the driver is loaded.
but it will not respond to dir /v /p H:\
