A downgrade is destructive, you will have to restore your data. That's been posted in several places on these forums and it'll warn you when you do the downgrade.
A lack of information regarding the physical switch is concerning...
The firmware itself if coming from another company, and Crucial tweaks it to their needs. That's very common. So they are somewhat dependent on their supplier.
Having just downgraded back to 1571, I'm much happier. Aside from performance being restored, my Macbook Pro is no longer cranking up the CPU and heat on heavy writes. I was noticing that my temps were clming to 80c with large write ops and after the downgrade I'm restoring 73gb worth of virtual disks and it's not breaking 60c.
I used a WinPE boot CD, USB stick to downgrade. On the MBP itself, you can boot off Windows 7 WinPE and run the wiper tool, but it says it cannot do anything with the disks. TO do the firmware downgrade, I did take the precaution of both setting the physical switch and using an older toshiba laptop. Looks like one could run the firmware upgrade from the Mac, it detects the drive, but I dunno about the AHCI thing.
I would like to see more action/communication from Crucial on some issues. OTOH, this is still a newer technology and early adopters with feel the pain. If you can't deal with it, you really should wait and see how upgrades turn out before doing them.
Even then, have a good recovery plan.
I'm pleased to report that Carbon Copy Cloner on Mac does great, and I've used it both to restore systems and migrate them to newer hard drives.
Total time spent with downgrade and data restore, about 2 hours for 129gb....not too bad.
It took me all of twenty minutes including the Ghosting work to do it. Your assertion that SSDs are new tech is somewhat ignorant. I was using SSD more than a year ago. There is more than enough information regarding SSDs to put out a product that doesn't need the consumer to beta test it for you.
Are you telling us that the responses here by Crucial to their customers is good? It is just not good enough when Crucial can not even answer a simple question like "is it safe to revert to the 15xx firmware while waiting for a fix to the fix". Is it too much to ask that Crucial release working firmware instead of throwing anything at us without even testing it in a real world situation? Who the hell actually tested this new firmware, the work experience kiddie? Surely it wasn't anyone that did any testing on the performance implications because they would have found that writes suffered a 50% hit.
I don't know what your affiliations in this matter are but I'm sure you don't represent the view of the majority of users here. I really don't get what the point of your post is. If it's to say that it's simple to downgrade, well derr, of course it's simple to downgrade. But that's not the point. The point is, why release a faulty firmware 17xx, then take weeks to release a "fixed" faulty firmware 18xx, then leave customers hanging in the wind when they ask simple questions like is it safe to continue using 15xx. If you hadn't noticed the upgrade data file made mention of a problem with 15xx but now that everyone is downgrading to fix there SSD performance that was rooted by upgrading to a faulty 18xx firmware we can't even get a simple answer to whether or not it is safe to use 15xx while Crucial hopefully within the next year manages to get a real working firmware that does what the drive specifications say it should do.
We need communication from Crucial not deafening silence. To tell you the truth, I'd rather that Crucial put back the 17xx firmware for download as it had better performance than the 15xx and probably had fixes that are useful. Come on Crucial tell us if it's OK to keep using 15xx or upload the 17xx firmware so we can use that while we wait for an hopefully final working firmware.
**Keep it courteous**
I'm a customer, just like you are.
No reason to be rude, and if you'd go back and read my post, you might see that I do have issues with the current situation.
As for your technical critiques, let's get a few things straight.
1. I took my time. No need to rush.
2. My downgrade time included taking machines apart, flashing, and restoring, etc. Pulling data off a 5400 RPM drive over FW400 ain't the fastest read source either. But fast enough for my purposes.
I was actually trying to be helpful and provide information that some may have found useful.
I get it, you're **bleep** off at Crucial. And taking it out on someone just trying to be helpful here is just a real stand-up thing to do.
while you're busy **bleep** about Crucial, I guess the fact that other manufacturers are having the same issues...
Firmware has issues. Always has, and like any other software, always will. Providing useful relevant feedback will help. After you've spent a few decades in the IT industry, you might figure that out.
At this point, Crucial, please get a little more active on these boards,
