I/O Errors after installing a new SSD
I have a I/O error problem after I installed an SSD to the original HDD bay of my MBP.
- Model: MacBook Pro7.1
- SATA II
- Year: 2010
- CPU: Intel Core 2 Duo
- OS X 10.8.5
- RAM: 4GB
- Samsung SSD 840 EVO 250GB (compatible with both SATA III 6GB/s and SATA II 3GB/s)
- Model: MZ-7TE250BW
- Firmware Revision: EXT0BB0Q
Bought a new Samsung EV0 840 (non-pro) installed as the main drive to my MacBook Pro 13" model 7.1, with SATA II. Installed Trim Enabler (Groths.org). From the very beginning for a couple of weeks the disk was producing I/O errors, sometimes even did not boot correctly. After a couple of weeks the SSD was dead.
Sent it back and received a new replacement.
After installing a new one, no matter whether enabled TRIM through Groths or Chameleon app I ran Blackmagicdesign Disk Speed Test and had again I/O errors after about 1-5 mins of the drive test. I disabled TRIM and the test went well for about 4 hours, but then again had the I/O error. After the I/O error had to take the SSD out, connect it externally via USB and run Disk Warrior to repair it to be be able to use it again.
After days of trials I gave up and put an old HDD back. Now testing the old one to see if the error still persist...
It has been quite a nightmare and I am thinking of either the MBP being dead, SATA cable to be replaced or the motherboard (logic board) dead....
Anyone experiencing similar issues? Any ideas about a potential cause of the I/O Error? Is Samsung 840 Evo 250 GB just a wrong pick and I should have chosen a different SSD?
Thank you very much
Is this a good question?
