Which software is able to (try to) remove bad blocks from an external 2GB Iomega SCSI drive, which is connected to an adaptec scsi controller

I tried several tools like, SpinRite v6, HDD Regenerator v1.51, Frobo Hard Disk Repair v1.0 and Frobo HDDBadSectorRepair but none of them work, they do not support SCSI devices or do not recognize the JAZ as a writable device

A simple low-level format does not do the job as it fails with an media error

Any suggestions for a better tools which does the job?

Only tool to recover SCSI that i know is Pc3000 SCSI .

MHDD does support SCSI devices, but can only perform Scan/LLF/Erase. Recovery/Reallocation is not available (however I have doubts that those iomega disks have the ability to reallocate sectors; I may be wrong though)
