Read CD-R in A1200

[Kronos]

with a 2X SCSI external CD-ROM drive

Thats an quite old drive !!!
The error-message sounds like the CD sends corrupted data.

May be that it doesn't like the used brand of CD-Rs or no CD-R at all.

Try to copy files from a "normal" CD to check that.

You might also check temination and power-supply.

What kind of controller are you using ? Has the CD an extra PSU ?

I don't think he would be able to "see" the files if the CD had the
wrong format. Must be some kind of read-error.

When I had my A1200 (with 3.0) I used a pre-IDE Mitsumi on a
PCMCIA-Contoller. CD-R were nothing more than a wet dream back
than, and when they finally appeared the disks were often unreadable
in older drives.

I even got a 16xTEAC here that will make nothing but trouble when I
feed it with a certain brand of CD-Rs.
