Solid State Drive Occasionally Seems to Disappear, Fine After Reboot

Hi everyone.
I'm running Arch 64 on an Acer Timeline 3810T, with an 80 GB SSD and ext4. A few times recently, it's like the drive suddenly disappears, and I'm down to ram. Resources fail to be found, icons turn to crap, and all unopened programs ranging from Firefox to ls are nowhere to be found. I can manage to bring up Gnome's shutdown dialog, but the letters are all boxes, and shutdown hangs after complaining about ext4, among other things. After a hard reboot, things seem ok.
fsck doesn't report any problems. What could this mean? I don't even know if this is a hardware or a software problem. Any help would be greatly appreciated.
SSD: ATA Intel SSDSA2MH080G1GC
fstab:
none /dev/pts devpts defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/sda1 / ext4 defaults,noatime 0 1
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
If more information would be helpful, please let me know.
EDIT: My rc.conf includes
MODULES=(acpi_cpufreq cpufreq_ondemand cpufreq_powersave fuse !snd_pcsp !pcspkr)
DAEMONS=(@syslog-ng hal @networkmanager @laptop-mode @avahi-daemon @alsa !openntpd !network !netfs !crond)

This still happens without running powertop, so that's out. Last time it happened I found reports like this in tty1:
EXT4-fs error (device sda1): ext4_find_entry: reading directory #24588 offset 0
and then:
INIT: Cannot execute "/sbin/agetty"
INIT: Id "c1" respawning too fast: disabled for 5 minutes
What could cause the filesystem to lose everything like this, only to find it again on reboot?
Thanks for any guidance on this issue.

Can you upgrade a MacBookPro hard drive from a "750GB Serial ATA Drive @ 7200 rpm" to a Solid State Drive easily? The info seems to say that it's as easy as plugging the new drive into a drive slot?

It's easy, but not that easy. You need to copy all the info from the drive currently in the mac to the new one before you install the new SSD. You can do this by downloading cloning software (I use CarbonCopyCloner because it's free)
Not to be picky but CCC is donationware, if you use it because of its quality you should send a little bit of money in appreciation, and as a bonus you get to turn the banner off.

Satellite Pro S300 EZ1514 - Cannot initialize Solid State Drive (SSD)

I have a Satellite Pro S300 EZ1514.
Recently I purchased a SATA II Cavalry 64GB SSD to replace the current hard drive. First I tried to install XP with SATA drivers streamlined in.
The install process recognized the SSD and did the initial file copy to it, but when it restarted to continue the install process the system would not boot from the drive.
Then I tried installing Vista Business 64 from the recovery disk that came with the laptop.
After initiating the recovery disk, the install process said the hard drive was not Initialized and to click OK to initialize now.
After clicking OK to initialize the system restarted only to end up on the same screen telling me to initialize the hard drive.
Then I tried to initialize the drive manually off of my desktop.
Plugged it into my desktop, initialized it and formatted it to NTFS. Plugged it back into the laptop to try Vista recovery again. And yet again the same screen shows up. Plugged the SSD back into the desktop only to find that the drive was no longer initialized and had to be initialized again.
Then I gave up and installed the SSD to my desktop as primary boot and it installed perfectly fine with XP. For testing purposes I then put the ssd with the pre-installed XP back into the laptop to see what happens. To my dismay the laptop would not boot and on top of that when I put the SSD back into the desktop only to find that the drive was no longer initialized and I had to reinstall XP again.
Conclusion:
It seems that the Satellite Pro S300 series is not SSD friendly and just the post it self de-initializes the Solid State Drives.
This seems like the logical conclusion as the SSD works perfectly fine on my desktop and the laptop is fine now with the old spinning hard drive back in.
Anyone else have this problem or a solution?
I would still like to put the SSD into my laptop for power saving.

Im using AHCI mode, but for testing I tried both and neither one worked. My bios is already up to the latest version and unfortunately the Cavalry site does not have any firmware updates yet. Again I don't think the drive is bad cuz it works perfectly fine on a desktop that had the same intel chip set and SATA controller. I think it's the custom boot agent that Toshiba uses at boot. Anyone know how to disable that agent and the intel boot agent as well? I read somewhere that the agents are not needed for the boot process and that in some cases they do cause issues like mine.

1 solid state drive or two ATA?

I have a Macbook with 2GB RAM. I run VMware Fusion with WinXP installed for .NET development. Sometimes it can bog the machine down. For example, when the sql server IDE is starting up. For the most part, it all works fine.
I don't see the option to get a Macbook with two hard drives. I imagine that would use up battery time quickly. Would one solid state drive be faster than one ATA drive in my case, since that is currently an option?

Thanks. I've been avoiding it after a couple of post that additional RAM didn't really improve performance to much. But I guess my case is different.
Do you think Apple RAM is best? I'd have to buy the full 4GB since there isn't a 2GB upgrade. Macbook only has two slots and right now I'm using them. Can't sell the 2GB on eBay either. I see they don't sell. There is one place that will give you something on your 2GB for 4GB upgrade. But I've read people sometimes have problems with their memory. Also, if I go with Apple RAM, it will help narrow down any general troubleshooting issues, since 3rd party RAM won't come into play. Just very expensive route.
Like it was said, Apple only buys from third parties. For the most part they don't even identify the RAM the install or sell as Apple-OEM parts like you see on hard drives.
Still - Apple at the very least uses modules that they're sure will work. The memory controller seems to be very fincky with DDR3 memory. There seems to be a lot of reports that people have gotten memory from OWC, Crucial, etc and had compatibility problems, including kernel panics. That's usually because there's something marginal about the memory's compatibility with the controller, where it passes power-on self test but eventually fails during regular operation. I guess heat could be an issue, as that slows down semiconductor switching speeds. I've heard of electronics that have been cryogenically cooled to improve performance.
At the very least you could get your memory from a retailer that has a compatibility guarantee. I would think by now Crucial or OWC have figured out what the problems may have been. Crucial.com is selling the 2x2GB kits at a pretty good price.

Upgrade my Macbook Pro 17" with solid state drive and RAM?

My MBP is a 17" mid-2009, 2.8 GHz Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3, Graphics NVIDIA GeForce 9600M GT 512 MB.
I am an architecture student. I use 3D modeling programs like SketchUp, Revit, AutoCad, etc. According to these software websites, my MBP is sufficient. However, when I'm running these programs, I get the apple "beach ball" a LOT, along with a lot of lagging even when I'm working on simple models. After doing some research, it appears that upgrading my RAM to 8GB (my model's max capability) and buying a solid state drive would help my MBP run much faster and much cooler.
My questions:
1. What brand and exact product #/link to this (if possible) of RAM (2 x 4GB sticks) and SSD should I purchase?
2. Which SSD GB option should I purchase? I chatted with OWC online and was given this variety of SSDs.
http://eshop.macsales.com/shop/internal_storage/SSD/Mercury_Electra_3G_Solid_Sta te
3. I was also given this product bundle recommendation. It's cheaper than buying everything individually, but I'm not sure if I need the tools and I don't understand the purpose/advantage of having the "OWC Express Silver Enclosure".
http://eshop.macsales.com/item/OWC/YSSDMP240/
I just want my MBP to run as fast as possible while running my modeling software w/o spending an arm and a leg if possible. But I don't know if it's worth the trouble and expense to upgrade my current MBP, which I love, or just getting a new MBP or Mac desktop. And if I should just get another Mac, I don't know which one I should get.
Another thing I have seen is the Mac Mini. Is it possible to plug this or any other external device to my MBP in order to accomplish my performance goals without having to modify my MBP or buy another Mac?
This is the first time I've posted any help questions to the Apple Support Community. I really appreciate any advise you Mac experts can give me. I called one of the Apple Stores, but I was definitely not satisfied with the inexperienced rep's answers.
Thanks!

1. OWC or Crucial are recommended sources for memory. You can usually find a 5% off and free shipping code for Crucial on retailmenot.com. On crucial just key in your system information in their memory selector.
2. Your system likely supports SATA II speeds, so the SSD OWC pointed to would work. I installed one in our 2010 mac mini and it's working well. I originally installed their 6G drive however it ran at SATA I speeds. Turns out the 3G which is specd for SATA II is what was needed and works fine.
3. The OWC package they recommended includes a case to put your existing hard drive in. That helps to be able to transfer your data back to the SSD then you can use it as a backup drive or as an external storage device.

I have a iMac intel 2.4 GHz core 2 duo maxed out at 4 Gigs of memory. I wondering if it would be worthwhile for me to put a solid state drive in in place of the optical drive in order to squeeze a little more speed out of this thing.

I saw a description of using a solid state drive for the system and certain other programs in order to create a snappier response. My iMac certainly seems to drag at times and the drives don't look prohibitively expensive anymore. The article was about macbook pros, so I don't know if the iMac is as good an example. Anyhow, any thoughts?
Jim

IMO, SSDs are too expensive, too small, and adding one to an iMac isn't a trivial undertaking.
As for improving performance, more RAM is better.

Can i install samsung 850 pro 1 tb solid state drive in my "macbook pro 2012 mid".

Hi, anyone know. can i install samsung 850 pro 1 tb solid state drive in my "macbook pro 2012 mid". any compatibility issues?

"In addition to TRIM, I just stumbled on this discussion. One of the posters is having some odd difficulties with that combination."
Yup and that's why I've avoided any 3rd party SSDs.
I only deal with:
http://eshop.macsales.com/shop/SSD/OWC
I've done 6 so far and no problems at all; formatting, installing nothing. Total no brainer. I did have a small formatting problem on my last one but I called them and solved the problem before the guy got on the phone. He immediately offered a return sticker (RMA) but I didn't need it and the MBP is running fine.

Optimisation -Solid state drives

Log Name:
Application
Source:        Microsoft-Windows-Defrag
Date:          5.1.14 15:27:29
Event ID:      257
Level:         Error
Description:
The volume System Reserved was not optimised because an error was encountered: The parameter is incorrect. (0x80070057)
Should the system on Windows 8.1 try to optimise a solid state drive?
Hope this helps, Gerry

This issue could be caused if Defragment take operation on SSD. And as we know SSD cannot be defragged.
I just want to mention that the above statement is not accurate as written.
The general wisdom is that one SHOULD not defrag an SSD. That's different than "cannot".
A file system indeed can be defragmented on any drive, including an SSD, though common wisdom is that the payback in performance to doing so is negligible, so doing a defragment operation just wears out the flash memory without any
real benefit.
Defragmenting the file system can ensure the data is read using fewer low level operations - i.e., a big block of data can be read in one contiguous chunk instead of several smaller chunks. Even as efficient as the most modern SSDs are, with near-zero
seek time, it DOES take some time for the operating system to prepare SATA commands and get them out to the drive across whatever busses and controllers are in place.
The difference in file system performance between a fragmented file system and a defragmented one can literally be hundreds of megabytes per second or even gigabytes per second when RAID is involved and the SATA link isn't a bottleneck. I
call your attention to the ATTO benchmark, which measures performance at various read sizes.
Therefore there is some current debate on whether an occasional (e.g., once a year) defrag on an SSD can optimize performance enough that it could actually be a good thing to do.
That said, with Windows 8 I'm not sure Microsoft's tools can actually be coaxed into doing a defrag on a (properly recognized) SSD. It was possible in Windows 7.

What's a good solid-state drive for my Pro 1.1, c.250-500gb?

What's a good solid-state drive for my Pro 1.1, c.250-500gb?

I only in the last months learned about the XP941 as an option, and for all Mac Pro models.
And that was in the middle of a long thread that led me to look further.
SATA Express meets the '09 MacPro - Bootable NGFF PCIE SSD ( 1 2 3 4 5 6 ... Last Page)
So the adapter is cheap $24-52 versus say Sonnet Tempo Pro SSD ($295) which is not even bootable in 2006/7.
No need for $15 Icy Dock. Does not take up drive bay or any of the 6 SATA II ports.
Yes up until last fall/winter the 840 EVO was fine, I have half a dozen ranging from 128GB up to 500GB and they work fine.
In the past I ended up using the Sonnet card just for data (graphic library for Adobe and iPhoto) and not the system.
Options are always good to have.

Solid state drive

I have 2 Solid state drives in my computer. For a while they worked fine. Then a couple of weeks ago the main drive stopped working. I got a error message that said "drive not found". The only way that I could get the main drive (PNY 480 gb) to work, was to reinstall the operating system and disconnect the second drive (SAN DISK 256gb). When I had both drives hooked up, the main drive would not boot-up. Then I would get the error message that said "driver not found". Why did the drives work for a couple of weeks an not they won't work togather. Will 2 SSD's work in my computer?

Hello @JLAR,
I have read your post on how the main solid state drive on your desktop computer has stopped working, and I would be happy to assist you in this matter!

Solid-state drive v.s 500GB @7200

Core i7, 8 ram, 128GB solid-state drive, 7200 rmp drive... will you help me to prioritize this list... put it in an most money worth order?
I am planning for a new 15" pro. I do graphic design... multiple applications open... CS5 (photoshop (manymany layers), ill, id), and some ms applications as well. No video editing.
Thanks!

Purely with respect to "perceived" performance, the single biggest thing in your list would be the SSD. The i7 will give you slightly better performance than the i5 options... but they are all excellent processors. However, with the size of the files you'll likely be working with either now or in the future, a larger rotational hard drive may be a better option than a faster SSD. After installing CS5, your Microsoft apps, and what ever projects you may be working on... 128GB can fill up quickly. Mind you... an SSD will make your system seem super fast. Another option would be to go with the SSD and keep your work on an external hard drive. However, this would sort of defeat the purpose of having an SSD as your largest (and longest loading) files will still be on a slower hard drive.
If you're set on an i7... then there isn't much debate there. 8GB would be a great option for the work you're doing. The only issue is the drive and you really just have to weigh the benefits of each and consider how you'll be using it.

Solid State Drive Upgrades

Hi guys,
My 2012 MacBook Pro (13" (non-Retina model) i7, 8GB) came with a 5400 RPM 750 GB hard drive.
While it runs fine for general use, I do a lot of pro-audio production & my system struggles while recording & mastering multiple tracks. Although 7200 RPM drives are usually the minimum requirment I thought I might as well keep up with the times & look into upgradint to a solid state drive. It's new territory for me, so any advice & additional information would be greatly appreciated .
In the past I've heard you should only go with drives that use a SandForce controller chipset... I don't know if that is still a valid requirment or not. Considering the size of my software & the audio files (pre-mastering), a 512 GB SSD drive is probably what I'm looking for.
Any recommendations anyone?
Also, while I'm here, if I take out my current system drive (which also contains a Windows 7 installation - via Boot Camp) & mount that into an external USB caddy, can I boot into those operating systems? Compared to my PC I see no BIOS access options in order to set drive boot priority, etc. Can anyone advice as to this point?
Many thanks for your time & kind regards,
mez

Take a look at the great information concerning SSDs here - http://www.overclock.net/t/1179518/seans-ssd-buyers-guide-information-thread/ Most of the coverage is pretty general but some of it is PC- specific. It's a good starting point.
I've a 512GB Crucial m4 series SSD that I've had since April. The nice thing about Crucial is that they have terrific Mac support. So do the drives from OWC, but I find them a touch too expensive.
There are likely a hundred users on here that have SSDs - and you may get a handful of opinions as to what the 'best' SSD is - I think that we tend to be 'in love' with the models that we own and that have given us good service (which is why I recommend Crucial - you don't have to take it to a Windows machine just to update the firmware).
You'll want to buy an external enclosure for your old drive, use Carbon Copy Cloner to clone your Mac partition and use Winclone to clone your Boot Camp installation. Then you can use the same external drive to keep a clone of your hard drive (again, I use CCC for that as well).
I'll keep an eye on this thread - should you have any further questions, write back.

SOLID STATE DRIVE, WHICH ONE TO GET? I NEED HELP me please!

So I am looking to get a SOLID STATE DRIVE but not sure which one to buy, I had gotten the intel x25 80gb but its too small and not too much different from my stock hdd. I mean sure its fast but not worth $200 thats for sure. I need a top quality, flying fast and worth the money SSD, SO WHICH ONE DO YOU RECOMMEND? I was going for the c300 from crucial the 128gb to be exact, but I have heard so many bad things.
My current setup is 13" i5 2011 version, with 8gb ram upgrade.
Im running OS X 10.6.7 and Windows 7 boot camp as well.
I need to know before I go to store tonight.
thanks!

Many users on this forum are very happy with OWC's line of SSD. They're located in the greater Chicago area but I don't think they have a retail store you can drop into. Great vendor in that they offer good prices, they specialize in Macs, great service and they're stuff is high quality. You can visit the SSD section at:

Solid State Drive For Macbook Pro mid 2012

Hi Apple Users,
I would really appreciate some advice, a link would be great too.
I am using a mid 2012 macbook pro with 16gb ram. After trouble here and there, slowing down here and there to the point I'm about to crack - solution = Solid State Drive.
I use a variation of 2D & 3D Programs to design with which include photoshop, maya, modo and Mari. My laptop just can't cut it most of the time and I need whatever I can so I can get jobs done without any lag, freezing or spinning ball while my laptop tries to catch up.
I have browsed around for A solid State drive but what I found is confusing or at least I get somewhat lost in my search of plug and play. My built in hard Drive of 500gb has 350gb spare so going for a 250gb SSD seems the sensible option as I use my external HD to store my files, music etc.
I don't want to open my macbook and fiddle too much so any suggestions which are near enough 'plug and play' would be great. I am aware I will have to take the casing from my macbook but I want an SSD that -
- Fits straight into my macbook pro from out of the box
- I can use my time machine backup to put onto my new SSD without trouble and Can continue getting my design work done.
Budget wise I don't want to spend over £250 and that reminds me I would like to purchase from A uk website or retailer.
Please Point me in the right direction of what SSD to buy.
Really Appreciate your advice.
Thanks

Any SSD with a SATA formfactor of 2.5" diameter and a thickness of 9.5 mm will be compatible with your MBP. Another possibility you might explore is OWC.

SSDs are indeed expensive, but is is not my place, nor anyone else's, to tell you how to spend your money. To dismiss your query by expressing personal bias is a disservice to you and the purpose of these forums.
I have installed in my MBP a Seagate SSHD (hybrid), 1 TB in capacity. The cost is a very modest premium compared to a conventional HDD. Boot and shutdown times are dramatically faster than before but it will not give the same performance as a SSD in processing resource intensive applications. This is simply to give you an additional alternative to consider.
Ciao.

How do I verify my T510 actually has the solid state drive that I ordered?

My machine sometimes makes a loud noise like a hard drive going nuts when it is moving alot of data (as I move data from my old machine to this one). I ordered it with a solid state drive but wonder if a regular hard drive was put in the machine by mistake. I checked Windows system information on the disks and it says I have a "fixed hard disc". I am not familiar with Windows 7 and wonder if it might say that even if it is a SSD.
Thanks
