Today's blog entry is going to be a bit dull, since it's just all the easy to fix Bellcom disks. No new Perl code is needed, these can all be fixed with the techniques described in past entries. In fact all of them involve just patching a single sector from another disk. The hardest part was finding the disks with equivalent content, but I've written before on how binary grep for content.

• Disk 670: Sector 113 empty, damaging WRITER.OBJ (Antic Writer). Patch sector from ANTIC\87_JUL.ATR, sector 403.
• Disk 606: Sector 129 empty, damaging FOOTBALL.BAS. Patch sector from ACE\ACEC071B.ATR, sector 206.
• Disk 441/442. Sector 466 empty, damaging PSPIC3.ACT. Patch sector from UMICH\CIS\BIN25.ATR, sector 554.
• Disk 605: Sector 113 empty, damaging ISLAND.OBJ (The Island). Patch sector from Page Six standard disk 251, sector 121.
• Disk 616: Sector 266 empty, damaging LASER.CHR (Lasermaze). Patch sector from Page Six standard disk 243, sector 266.
• Disk 478: Sector 320 empty, damaging TIMP.SPL. Patch sector from Page Six issue disk 45b, sector 288.
  

There are about ten more disks in the Bellcom collection with identifiable damage. I've yet to find exact matches for the sectors in my collection of disks for these, so I'm going to build up my collection of user group disks in the hope of finding some further easy fixes.
