Can anyone help with this ?
Bought a new 250Gb Crucial SSD and fitted in place of the CD Rom.
Now having all these issues and it won't work.
Have I messed up and not its good for the bon or can someone help me out. ??
Thanks
MacBook Pro 13″, macOS 10.15
If this SSD is in the Optical Drive bay, then perhaps the cable is not sufficient for working with an SSD. Apple never designed this miniature cable to be used with a high speed SSD. Or maybe SSDs just are not compatible with your optical bay SATA controller. This is not uncommon. You can try connecting the new SSD externally using a USB SATA Adapter, drive dock, or enclosure to see if the problem is with the optical drive bay or the SSD.
FYI, I notice you are using an MX300 SSD in the main drive bay. You should make sure that SSD is running the most current firmware since we've experienced a lot of problems with the older firmware on our organization's SSDs. The problem only occurs when the SSD tries to reallocate a bad block and is unable to do so resulting in data loss. I highly recommend you update the MX300's SSD firmware. You can use the downloaded firmware .iso file (must first extract the .iso from the .zip file) as a source for Etcher to create a bootable USB SSD firmware updater. Option Boot the USB drive and select the orange icon labeled "EFI".

To make sure your MX300 SSD doesn't currently have this issue run DriveDx and post the report here so I can examine it. If the SSD shows this issue, then the only way to fix it is by updating the SSD's firmware and using the SSD's built-in hardware secure erase feature to reset the SSD to factory defaults.
Upgrading the SSD's firmware should not cause data loss, but it is a serious update so there is always a possibility of data loss even if it is very unlikely. Make sure to have a good backup just to be safe.
FYI, you should always have frequent & regular backup especially when using an SSD since it is impossible to recover accidentally deleted data from an SSD plus an SSD can fail at any time without any warning signs. Make sure to backup both SSD and any external drives which contain important & unique data.

Yes your 750GB hard drive is in really bad shape.
Please post the full DriveDx report for the MX300 SSD by clicking "Save Report" within DriveDx which is in the upper right corner (make sure to first select the MX300). Then copy & paste the contents of the resulting file here using the "Additional Text" icon which looks like a piece of paper. I need to see all the attributes to know if there may be an issue.
Try erasing the entire Device "CTX250MX... media" again.
If it fails again, erase it agin.
when you get tired of this, you need a new drive or a new drive cable.
If you buy a new drive, try to get one ≥500 GB. Smaller drive can be really slow.
Make sure you are formatting it at the device level not the volume level.
The SSD was a 250gb for some some music and pictures so I can make some more space on my 525 SSD which is also my boot up disc.
The 250gb SSD was put as a second into my CD Rom as I currently have a standard 750HDD in there and I was just looking for something slightly smaller and quicker than a 750 HDD.
I have tried and tried to Erase it, Run a first aid on it and remount it but nothing seems to work.
I have since popped my 750HDD back in and there is no issues or problems and it works a treat.
Thinking im just going to hit it with a hammer and then buy a new 120 SSD or a 250 SSD
Now that I have done this im now just looking to take the 750 HDD out and out in a small 120 HDD and then take my MX300 500gb SSD out and put a new 1T SSD in its place and start from scratch.
Can you Advise what the best SSD is for this MacBook Pro ?
Hi There,
Once again THANK YOU so much for all this help and advice.
I have now just bought a MX500 1TB SSD and I will install it and take it into my local apple store and get them to put all the correct software on for me.
I will take this MX300 500gb SSD from this Mid 2012 MacBook which im using at the moment and put in into my Old 2010 MacBook.
Im now going to be running a MX500 1TB SSD from crucial and a small 120gb HHD in the optical in my 2012 MacBook Pro so it will be working perfect with enough storage and fresh drives.
I have no idea how to fix the firmware on the MX300 so I will just fit it to my 2010 MacBook and leave it in the box.
Thank you for all your input and help
Anyone Shed Any Light On This Or Shall I Just Bin The SSD & Start Again ?
Thanks
Wow,
Very Very helpful and has explained a couple of things.
When I got this MacBook there was a 256 SSD that was the boot up drive and the 750 HDD in the optical drive.
I took the 256 SSD out and put my Cruial 525 SSD (MX300) into this and it is my boot.
I was under the impression that I could take the 750 HDD out the optical drive and put another smaller SSD in there.
I have had my MX300 ssd for many years and if im being honest what you have said I fully understand but way above my head.
I have downloaded DriveDX and here is the results
First Picture is the 750 HDD in the optical Drive
The Second Picture is of my Crucial 525 SSD (MX300)

Sometimes you can. Try reseating the cable to the Logic Board in case it has gotten a bit loose. Once you determine if the new MX500 SSD is good you can try replacing the cable in the optical drive bay if reseating it doesn't help. I think some people have tried to shield the cable, but this is very difficult to do without shorting something out.

I discovered that the MX300's firmware had a really bad bug where the SSD could not properly reallocate a failing block. So the bad block remained in use so any data stored within that stuck bad block became corrupted. A later firmware update fixed the problem so future bad blocks would get properly reallocated, but if the SSD already had a stuck bad block the firmware update wouldn't help until the SSD had a hardware reset to factory defaults which also erases the SSD.
Plus the later firmware helped to increase the performance of the SSD when writing GB's of data in a short period of time.
The MX300 SSD looks to be in good shape. After upgrading the MX300's firmware you shouldn't have to worry about any bad block reallocations getting stuck. FYI, unlike hard drives a bad block on an SSD usually doesn't mean the SSD is bad.
We've installed the Crucial MX500 series SSDs in many of our organizations Macs without any issues. It is getting much harder to find good SSDs these days since most vendors try to hide the technical specifications so users cannot tell which SSDs are good and which ones are very slow budget economy models. Stay away from the Crucial BX500 series as it is a very slow drive.
Currently my first choices would be Crucial MX500, Samsung EVO or Pro models, and possibly OWC Mercury (least favorite). There may be a couple of others, but they require too much research to confirm specs, quality, and performance.
