Hibernation has nothing to do with battery calibration per say. It's just that when you run your battery down, the system will shut down cold instead of hibernating. You will lose anything that's in memory, so you should save any changes you have in applications before doing it.Does anyone know if a battery calibration is still possible even if hibernation is turned off (i.e switching to hibernation 0)?
I've just turned off the "put the hard disk to sleep when possible" for both "on battery" and "on power"...
Question: THis should keep the mac away from future problems, right
No. What you want to do is go to Energy Saver pref pane and set the "Computer sleep:" slider all the way to the right to "Never" under both battery and A/C power so the computer will not go to sleep on its own. You can still sleep it by closing the lid or by the Sleep menu option in the Apple menu.
Hi,
I just contacted the OWC tech support regarding the hibernation issue and a firmware updater for OS X. He confirmed the hibernation issue, but according to them the current FW does not have problems with sleep mode.
Also, a firmware updater for OS X is on the way along with a patch for the hibernation bug.
What do you think? Are they reliable? They better are...otherwise no more sales.

That disables suspend to disk functionality entirely, so you would't hit any of these SSD issues.Also, I have made the changes discussed here: Optimizing Mac OS X for SSD drives. That does include switching hibernatemode to 0 and disabling hard drive sleep.
I prefer that myself since it also frees up disk space equivalent to installed RAM if you delete the sleepimage file. In my case that's a 8GB of available space recovered.That disables suspend to disk functionality entirely, so you would't hit any of these SSD issues.
We can appreciate all the sentiments in this thread and wanted to reach out to say we hear you.
We have been and continue working diligently on this issue with SandForce, and while it doesn't affect 90% of those that purchased and are using an OWC SSD, it still is something that is a high priority for us to resolve.
Unfortunately, during a cutting edge product's evolution, issues can crop up despite all research measures employed during development.
To ensure the confidence in purchase, we were the first SSD manufacturer to offer a 30 day money back guarantee in the event of any dissatisfaction. And we offered this from day one of this product's introduction...not just a band-aid fix for this isolated hibernation issue.
We truly hope a new firmware update that solves this matter will be forthcoming from SandForce in the next several weeks. In fact, we have been testing the next firmware release version since mid-February and we hope to have an announcement shortly.
We want to thank you for your patience in this matter and should have you have any additional needs, please do not hesitate to contact our customer service/tech support departments.
Sincerely
OWC Grant
With luck I wont experience the issue with the OWC, as I believe the Crucial uses the very same SF1200 controller in its SSD's.
Crucial is using a Marvell controller in the C300's, not Sandforce.

Any update on the OS X based firmware updater that was promised on your web site? Or even a Linux/FreeDOS CD-Rom installer would do the trick. The current solution OWC of installing Windows under Bootcamp for firmware updates is not very attractive from a user standpoint.
A double AMEN to that - having to install anything Windows to update SSD firmware = NO OWC PURCHASE !!!
Does anyone have an OSX firmware updater right now?
I'm hoping that OWC will bring out new drives soon along with an OSX firmware updater and a hibernation fix! I guess I can dream...
The current SSD Apple sells in the CTO/BTO computers are slow compared to Sandforce controlled drives (OCZ, OWC, and some others) and also the Apple versions cost much more. Do not avoid buying aftermarket because you are afraid of changing one. It only involves 10 screws, 4 pegs and a plug.
Anytime soon till June is there ETA for that... *sigh* I'm really thinking about just giving in and buying a SATA 3Gbps drive (I have 2011 MBP with SATA 6Gbps).
...
I'm preparing to order an MBP 2011 13" and was planning on adding an aftermarket SSD after seeing discussion here in the forums, however after reading this review I am concerned about what aftermarket drive will give me the highest reliability/least concern. (I didn't really want to BTO as its the most expensive option, since I can order a stock PC from out of state save a couple hundred in tax as well as the higher price of the Apple SSD). While I want speed, it doesn't have to be the fastest on the planet. Reliability is most important.
Am I being overly concerned about fearing an aftermarket SSD? Is TRIM a desireable feature?
Thanks
