I did First Aid (which still said the drive was OK) and tried to reformat in every available format (except NTFS) again on my MacBook Pro 13” (Mid 2009) running MacOS Monterey (12.2). I then attempted to format in ExFAT, and then FAT32 again, which failed again.Īt this point I was completely exasperated, and settled on formatting it on another machine. I attempted to format in MacOS Extended (Journaled), which failed again. I then tried formatting in APFS, which failed once again. I tried First Aid, and it once again said the drive was OK. It now appeared, though still as an uninitialised drive. I followed the prompt to initialise it, and opened disk utility. Frustrated once again, I left the drive connected, and after about 10 minutes it appeared as an uninitialised drive. I used the terminal command “diskutil list” and it was not listed. Since the drive was visible in System Information, I figured the drive must be hidden somewhere.

When I restarted the computer, the drive was not recognised in disk utility, but was visible in System Information. I then tried to eject the drive, and it would not eject.įrustrated with this, I disconnected the drive (without properly ejecting) and then installed the drive into a CD to SATA adapter internally. I then tried to format the drive as ExFAT and FAT32, which also failed. I ran First Aid again, which reported success.

I then proceeded to attempt to format it as Mac OS Extended (Journaled), which also failed due to a mount error. The format failed due to not being able to mount the disk and I ran First Aid, which succeeded. When I plugged it in initially with a USB to SATA drive adapter it showed up in disk utility and I tried to format it as APFS. The drive is a Seagate Laptop Thin HDD, 500gb (Model Number is ST500LM021). I am running MacOS Catalina 10.15 on this laptop. I have bought a hard drive for my MacBook Pro 15” (Early 2009). (Please bear the long background, I want to explain all of the events that lead up to this problem) Normally performing these resets separately is fine, but years ago OWC support had me perform these two resets back to back to get an OWC third party SSD seen by a very old MBAir which had the odd small hard drive/SSDs.Ĭheck the documentation for the SSD to know if macOS 10.12 is even compatible with this SSD.Hard Drive not visible in disk utility or terminal after failed format.

Sometimes it can be tricky to perform the PRAM Reset immediately after an SMC Reset on these USB-C Macs since the SMC Reset can sometimes cause odd power on behavior. Try an SMC Reset followed immediately by a PRAM Reset (hold the PRAM Reset for at least two chimes if possible). I omitted macOS 12.x Monterey since that installer may not work with third party SSD if Monterey had not been previously installed on the laptop. Or a Mac from 2015 to 2023 for macOS 13.x. For macOS 11.x a Mac from Late-2013 to 2020. Generally you need a Mac from Late-2009 to 2018 to create a bootable macOS 10.13 USB installer. You can also create a bootable macOS 10.13+ USB installer if you have access to another Mac:Ĭreate a bootable installer for macOS - Apple Support In the non-touchbar model the SSD does have a high rate of failure and is usually the component which fails.Ĭan you boot into Internet Recovery Mode using Command + Option + R to access the online macOS 13.x Ventura installer? Either this SSD requires using macOS 10.13+, or the SSD is not working, or the SSD was not the part which failed. You are booting into macOS 10.12 Sierra installer which is not showing the physical SSD in your screenshot of Disk Utility.

I'm thinking that if I find this adapter I could install macOS on it using another macbook. I'm looking for USB enclosure for this SSD but I found nothing. The only thing that changes is the capacity. I bought an original Apple SSD, you can see in the photo the old SSD and the new SSD. I already created a bootable macOS installer with Monterey on USB flash drive as '' Create a bootable installer for macOS'', but I'm not sure how use it. I tried the SMC reset and PRAM reset, but nothing happened. I don't get the error message any more, it asks me to select the disk where I want to install macOS, but the disk list is empty. When I boot into Internet Recovery Mode (with cmd+ R) to access the online macOS (Sierra) installer, I've this error message : ''The installer information on the recovery server is damaged''.īut if I boot into Internet Recovery Mode with cmd+option+R as you said, the graphical interface of the recovery mode changed. It's friend's macbook, when she went in apple support, they told her to replace herself the ssd because it's easy and cheaper if apple does.
