There is indeed a patched Kickstart called Level42 (Kick1.2), which had a diskcopy Programm patched into Kickstart (leaving out some other suff of kickstart).
Perhaps you find someone with this kickstart. (I can't find mine anymore).
With this kjickstart you can make a copy of the workbenchdisk, which is then written onto a fresh disk.
The benefit of this diskcopy prg is that it tries to read atrack severel times until it gets valid data too write back.
It seems to mee that your drive cannot read anymore cylinder 0, where the bootblock is.
Perhaps blowing air into the drive can help.
There is also a kickstart hack which gives you a cli instead of the wb-handpic, but i don't remember its name (HQC kick???).
Or find someone with the beta kickstart1.4 specially for A1000 (very rare sorry). There you could get into the bootmenu and chose booting without startup-sequence. You will get an complaimng requester about not beeing able to read the wb.disk, but after clicking away the requester you have a cli. Now do the following:
1. Write-Protect your WB-disk.
2. Insert it into df0:
3. enter "df0:c/copy df0:system/format ram:"
4. enter df0:c/copy df0:c/install ram:
5. put a empty (or obsolete) disk into df0:
6. enter ram:format DRIVE df0: NAME Workbench
7. enter ram:install df0: (makes the disk bootable)
8. press ctrl left A right A (softreset)
Now the a1000 should at least boot from your new disk into a cli.
Exchange above "format" (step 3) with the diskcopy command and give it a try:
ram:diskcopy FROM df0: TO df0:
(always writeprotect your important disks)
At last. there is a patched kickstart called "UFO Final Antivirus kick". Give that a try as it can eliminate some bootviruses and install the C= bootcode, BUT don't use this on Original Gamedisks, as it can overwrite the custom bootcode !!!)
I can send you that UFO kickstart via snailmail, but that can take some days.
