Problem with a SSA drive

I've a problem with an IBM StorageWorks - Seagate SSA drive, model ST373453LC (IBM P/N 24P3733, Type S53D073, 72,8 GB 15K - USCSI 4 - 320 SSA). I bought this disk used but working; it came from an unknown IBM SSA storage array. I've removed the SCA - SSA adapter (IBM 18P3051 - 001 - R0) and i tried to install the drive with a "normal" SCA tray in my NetFinity 5500 M20. The RAID controller is an IBM ServeRAID 4M. The problem is that the disk is "seen" by the controller, but I can't access it in any way. If I connect it to an Adaptec 29160, at the CTRL + A prompt, after the spinup, the controller says "SCSI ID0: device connected but not ready" (and the disk can't be accessed, of course).
Some ideas regarding this problem...?
Thanks in advance!!!
I apologize for my poor English...
