Here in January of 2015 I'm still using my modified SSD Enabled '08 and Crucial M4-CT256M4SSD2, 256.06 GB modified MacBook Pro. Here's my original post. It is STILL performing well, However, after a botched AFP file transfer that yielded over 242,000 0 byte entries for one file in the Document directory - I noted some behavioral problems, like Spotlight stuck indexing a lot of nuthin'. BUT The end result is Good News.
Disk Utility suggested reformatting my SSD as it was unable to repair the filesystem properly after I botched the attempt to delete the spurious files. So I
- Turned 'Trim Enable' to off, re-enabling Kext protection (this was of no account)
- Backed up the root drive via SuperDuper to a partition I keep for the purpose. This also was unnecessary (except perhaps for my peace of mind).
- Rebooted and entered recovery mode, reformatted the Crucial SSD and recovered from Time Machine. This turned out to be the fastest fix for a not completely clear problem.
- Downloaded Crucial's latest (070H) version of the firmware for Mac OS. It's an ISO file you burn to CD (or DVD). I did this with my original SuperDrive that lives in the case I got From MCE (original post).
- Rebooting and holding down 'C' before the Apple logo appeared, I followed the onscreen directions to update my Crucial's firmware. Reboot again.
- Verified via (Apple)->About this Mac->System Report->ATA SATA that the update was being reported to Mac OS X
- Re-enabled Trim Enabler 3.0 which took two re-boots - one to disable Kext signature verification (Apple doesn't allow signing any longer of 3rd party Kext's), and the other to turn on Trim Enabler.
My machine is again running smoothly - fast as ever - even if it'll be 7 years old in a few months. In computer years about Nine-Hundred and Eighty. Almost Biblical.
PS - Sorry for gushing - but a great experience should give credit to whom and where due. I have not received or sought any consideration (or acknowledgement) from any of the mentioned vendors. But each has provided me with great product, and made my life a lot better.
