hard drive error

I had a hard drive which was formatted with the MPC2000. It has 26 sections a-z, but the mpc4000 does not recognize anything in the second half of the drive letters m-z (or there abouts) it sees the letters, but none of the programs or sequences...please help.....

How did you format it with the mpc2000? Are you talking about a SCSI hard drive external> ? I'm trying to figure your setup out so I can help...

yes an external hard drive that was formatted with the mpc2000
