Bad block list and defragging drive problem.

[kvasir]

Hello all, I have a 1.2 gb work: partition on my A1200, using SFS filesystem, and there seems to be a bad block somewhere towards the start of the drive. I've been trying to use sfsdefrag, as the files are scattered in a way similar to buckshot from a shotgun round. When it get to one specific spot on the drive, the hard drive shuts down and makes a sickly grinding noice. After a second or 2, it will spin up again, and repeat until I reboot.

What I need to fix this is:

A block by block scan of the partition
A way to map these blocks out, I beleive this can be done with hdtoolbox, but I need a refresher on how to do this.

Both previous things that are compatable with SFS.

Failing that, I might be able to format the drive if sfsformat can "skip" blocks, but this would require transferring about 700MB over an ethernet cable, hardly the most exciting part of my week....

Any suggestions?

@ all
Thanks for the help! Just an update, spent last night tying up 3 computers (My 1200 w/ ailing HD, My windowsXP laptop, and my Wife's computer). Dumped all my important files accross to my laptop over wireless (for some reason my wifes computer won't accept a SAMBA connection from my 1200), whilst checking my financial aid status and customizing my new cellphone on my wifes computer, then killing time on the rest of the backup with a game of Homeworld (before semester starts and homework requirements prevent such frivolties). Also looked into my IBM thinkpad PII, that I picked up for $10 at a rummage sale not too long ago, which sports a 5gb drive thats old enough to be recognized by my 1200. (I don't have a working 4x-eide card yet, the one I do have requires a tower case, which I'm saving pennies to buy, so I'm stuck with laptop sized IDE drives for now) I have a couple of probs with the backup, though. I have 1 MacOS partition that the Amiga can't access directly due to a lack of a Macintosh filesystem, and 2 windows partitions (3.11 and win95 for pc-task) that will copy fine, but eat the rdb block, requiring a re-install. not too big a deal for 3.11, but 95 will take all friggin day.... Also, my internal floppy isn't working all that well. I still need to sync the file attributes between the backup (on Windoze crap NTFS) and the Amiga, while I believe theres a proggy on Aminet for this sort of thing, I can't remember where... Plus I want to get my wifes computer with a 120GB drive accepting smbfs mounts, with her being hardwired into the router the backup would go much faster. The drives actually done this before a while ago, and it just takes a reset to get around, but now it only does it during a defrag, like sfs is already skipping that block. At first it was acting more like an overheating problem, and possibly the drive had a safety shut-off of some sort. Haven't been able to dig too much info on it other than here. ( 2.1 GB internal 2.5" IDE drive ) Anyway its alot of fun about to be had here. I can't do a UAE dump on it as it is a 2.5", and I don't have an ide adapter for the tower size ide port (pin amounts escape me this few cups of coffee in the morning, I know one of em is 44 pin :-D ) This also goes for reformatting the 5 gig drive... Ugh.. will have plenty to do this weekend. Thanks again all!
