Another possible thing that zeroing all data may fix, is blocks that are "weak" magnetically, though this is just my theory.The Covid-19 pandemic and the social distancing that followed have affected all walks of society, also education. Blocks that are bad like this won't be detected by utilities that scan for bad blocks, since these utilities just look for blocks that are so messed up that they can't be read at all-these utilities can't know whether the data stored in those blocks is correct or not, they only detect scrambled "header/footer" identifiers that bracket the data in each block, or blocks that sit on a location on the disk where there's actual physical damage. How these blocks get bad in this way, I don't yet know-possibly the result of crashes, buggy software, etc.-the usual. These blocks can have wrong data, etc., and zeroing all data is the only process that actually erases them (and all the other blocks on the drive) and resets them to a condition that Apple is happy with.

Choosing to simply initialize a drive doesn't erase all the blocks on the drive-it just removes all file entries from the directory tracks, and does nothing to actually repair any messed-up blocks that the Mac OS reads as part of its process of interacting with the drive, including the directory tracks, but also including the boot blocks, etc. I've increasingly been finding that the 'zero all data' option fixes a variety of hard drive problems that no diagnostic utility can either fix, or can even detect. Works for me every time (I fix Macs for a living, so I've seen this many times). Sometimes you have to replace the RAM several times during this process, with different RAM each time, until you get OS 9 to boot and let you run the firmware updater.

But again the effect is only temporary, so you need to quickly update the firmware once you get the Mac running, which will clear up any remaining messed-up video too. There are ways around this if this happens to you mainly they involve removing the RAM and installing different RAM, which often gets the logic board running well enough to allow you to boot from an OS 9.1 - 9.2.2 hard drive and update the firmware, since when the logic board sees a new RAM configuration, it TEMPORARILY resets some of the scrambled settings as part of its process of storing the new RAM configuration, usually long enough to allow the Mac to boot and allow a firmware update simply resetting Open Firmware sometimes does the trick, but replacing the RAM works more often. Now Lynn (the iBook) is now enjoying Aqua goodness!Īctually, it won't fry the logic board as such, but it can scramble the firmware chip which is on the logic board, and the Open Firmware settings, resulting in anything from weird video but a Mac that works otherwise, to a black screen and no boot. Then I used Carbon Copy Cloner to copy from the mounted backup image to my super clean ibook. From TTP4's output: Precheck StructuresThis test checks the readability of the various volume structures.Precheck Structures The only thing that worked - the only method that allowed me to boot into my backup image - was using Disk Utility's "Zero all data" and "8-way random write format".

And running Tech Tool pro 4 resulted in a failure of repairing volume structure.

All of them left me with a circle with "/" through it.

I tried Carbon Copy Cloner, Disk Utility's restore function, ASR from the command line and NetRestore. A simple partition on disk utilities didn't work.What would happen? Well I'd erase and then partition the drive as HFS+journaled (same as the backed up disk image) and restore it.A simple "erase" in Disk Utility didn't work.But now my iBook wants to get back to Panther, so I'll restore the image I made of her HD. I've put it on my secondary hardisk on my PowerMac. I've been trying Yellow Dog Linux 3.0.1 on my iBook, and it's been great.
