FastATA 4000

Need more info, like versions of Kickstart (3.1 40.70 for A4000 probably).

The CD-ROM will need a CD file system to get mounted - is at least one free one on Aminet. Copy it to L directory should help get CDs mounted and recognized.

True Acill, latest/current version of ATA4000 does come with AllegroCDFS...

Not sure if OP bought new or second hand, but at least the freely available AmiCDFS will let them read disks. That was my thinking. It's not the fastest or fully featured, but at least it should work.

I don't know about the CF cards, but I suspect the problem with the hard disk is, it was configured as a master, and is now on a slave channel. Check the jumpers on both the CD-ROM and the hard disk to make sure they are set properly.
