"Vol: has a checksum error on disk block xxxx"

[Tenacious]

In the past, I would swap out the hard drive after receiving this message.  Now, I'm running out of hard drives.  

After all this time, does our favorite OS offer a way to re-map the bad places on a drive and continue on?  This partition is currently formatted with FFS.

Thanks for the advise and solutions Thomas, Zipper and Thomas!  

Yes, it is a SCSI HD, under 4GB in size.  The partition in question is only 700MB.  The machine is an A2000 with a GVP 68030 accelerator and A2091 running OS3.1 with BetterWB.

I used PFS2 years ago and really liked it.  I haven't formatted a new system with it since the free version came out.  But now, I'm tempted by this.  There are probably better tools in PFS for this kind of problem.
