| Feb 23, 2017 at 9:54 | comment | added | Monomeeth♦ | That means what I said in my earlier comment has now happened: that Disk Utility has flagged the bad sectors and ensured they are not available to the OS. It's fixed in the sense that those bad blocks won't be a problem. However, there's no guarantee that you won't encounter new bad blocks. | |
| Feb 23, 2017 at 5:03 | comment | added | Luke James | So the secure erase worked and didn't throw any errors, and I was able to reinstall the OS. I ran the 3rd party program and it's indicating the drive now has 0 bad sectors but 21 reallocated bad sectors. Does that mean the issue is fixed? Thanks again for your help. | |
| Feb 23, 2017 at 2:04 | comment | added | Luke James | Ah, something weird is going on actually. The "secure" erase only took a few seconds, which seemed off, so I restarted and rebooted into Internet Recovery instead and it's now taking an estimated 1.5 hours. Will update. | |
| Feb 23, 2017 at 1:47 | comment | added | Monomeeth♦ | Well, if you've done a secure erase then Disk Utility will have flagged any bad sectors as such and ensured they are not available to the OS. The question is whether those bad sectors are an indicator that the drive is on the way out? In my experience, a drive with bad sectors can suddenly start deteriorating badly with countless more bad sectors, but I've also seen drives with bad sectors last for years after a full reformat. That's why for me I'd now use the SSD as my main drive, and repurpose the old one as an external drive (e.g. it could be a second TM backup drive, etc). | |
| Feb 23, 2017 at 1:33 | comment | added | Luke James | Do you think that the drive should be okay then? I forgot to mention some 3rd party programs indicated there were 20 bad sectors, but is that something Disk Utility should have caught afterwards? | |
| Feb 23, 2017 at 1:25 | comment | added | Monomeeth♦ | @LukeJames I guess that is a personal decision based on what you can afford and how important the data is to you. If it was me, I'd keep the new SSD and install it into the MacBook and use that as my main boot drive. I'd then keep the old drive and use it in an external case/enclosure as another drive. Cases/enclosures don't cost much at all. But, as I said, it's a personal decision for you to make. | |
| Feb 23, 2017 at 1:19 | comment | added | Luke James | Hello again. I ordered a new SSD and was waiting for it to arrive to try this... and the high security erase worked (I actually did it a few times to make sure, and once on the highest security setting). It's now recognizing the original drive and allowing me to re-install OS X on it, and Disk Utility says it's fine. Is it possible this is a fluke, or should I no longer bother with the SSD? Sorry for the bother again. | |
| Feb 14, 2017 at 21:17 | comment | added | Monomeeth♦ | As for installing macOS on a new HD, you can do this by using Internet Recovery. Another options is to download the installer using another computer and create a bootable USB. Or you can start your Mac in Target Disk Mode and use another to do the installation. Either way, you'll find answers here on how to do the installation. | |
| Feb 14, 2017 at 21:17 | comment | added | Monomeeth♦ | If you do a Time Machine backup and then go ahead and do a totally fresh installation of your system, then you shouldn't have any issues migrating data back from the TM backup. Your system itself won't be migrated back from TM, only your files etc. If you don't already have backups previously, I would probably do a full TM backup first and then manually copy across your most important data onto another drive. But if you've already got corruption on your main drive there's nothing you can really do about it now (unless you have older backups). | |
| Feb 14, 2017 at 17:43 | comment | added | Luke James | By backup, do you mean just transferring over the files to a drive or a TimeMachine backup? I'm scared that something in my file system is corrupted or something and if I restore from a TimeMachine backup it'll restore it with the same corruptions/issues. Thank you for the suggestion; I will try reformatting, but I have no idea how to go about re-installing the OS from there if it won’t show up in the menu in Internet Recovery Mode. | |
