When I bootup my 2010 13-inch MacBook Pro I am stuck on the bootup screen.

i went into verbose mode and I got this text and ended here as well.

Your hard drive is corrupt. Boot with the CD or Thumbdrive.

BEFORE you try and repair it or anything backup any data you want or need.

Then try the Repair Disk in Disk Utilities.

I would reinstall after that.

If that doesn't work come back here, tell us what happened, and I or someone will guide you further.

Thanks Bifurcator.

I only now got around to extracting the HDD and putting it on an an external enclosure to backup my "User" directory.

Now, Mavericks is taking almost 10 mins to initialize the HDD and I get the error message below of "OS X can't repair the disk".

Would anyone know how to fix this? Can I just do a simply reformat and I can reliably use the HDD again?

Disclaimer: I am not an Apple use, other that tablets and phones

Copy your data files to other media ASAP. As for whether or not you can use the drive reliably after reformatting depends on the cause of your problem. If due to a head crash, no. If due to other magnetic field corrupting data, most likely you can use after reformatting. Sometimes mechanical wear throws off the indexing just a tad and a refrmat will allow the drive to work a bit longer. But, drives are so cheap, I'd replace it and have a few more trouble-free years. You may wish to go with an SSD instead. The Samsung 840 EVO, Crucial M500, and Sandisk Extreme are highly-rated choices.

Copy any files over that you can ASAP to an external HDD using the boot CD or thumbdrive, and then swap out your hdd.

You won't be able to fix this, and it's common, happens to most computer users by the 4th year of owning a computer. If you're unlucky, it'll happen sooner.

fix this - as in the HDD, you'll have to replace it.

Way ahead of you.

240GB Crucial M500 with firmware MU03 on a 2010 13-inch Macbook Pro with Superdrive through SATA 3Gb/s (300MB/s) interface. Clean install of 10.9.1 + other updates. TRIM not enabled as it was recommended by a Crucial employee that the built-in Garbage Collecting is sufficient.

Before I reformat the HDD and designate it a dummy HDD for trivial data what else do I copy other than "Users"?

Application, System & Library are were not added to actively by me since 10.8.x.

What you decide to migrate over is up to you of course. My question is why the slow speed for an SSD? Most of my SSDs peg the SATA2 limits but the screen cap above shows about half that and what I might expect from an ordinary FAST HDD. What am I missing?

Bifurcator - Probably limitation of a slower machine not being able to fully utilize the speed of the SSD. Same sort of results from my MBP with SSD and my newer mac desktop with SSD.

p.1 #9 · p.1 #9 · 2014 SSD (was Mountain lion/lion doesn't get passed boot)


Mine is older - 2006 compared to his 2010, and I get faster speeds than that - as mentioned I max out the SATA2 buss at between 295 and 305 MB/s for both read and write in black magic's DST. I dunno, no buggy tho, I was just wondering.

With a single 1TB Seagate (single platter) Barracuda I can get 210 Write and 195 Read in BM's DST on that same MP-2006.

The SATA II interface offers a max theoretical transfer rate of 300Mbps.

The SATA III interface offers a max theoretical transfer rate of 600Mbps.

Most new SSD's running on an Intel (not Marvel) slot will average ~400/400. If you're getting better transfer rates than that on SATA III, I'd like to see it.

Bifurcator,

Crucial M500 are mainstream SSD that put $/GB & reliability as a priority. Published read for the 240GB SSD is 500MB/s and write is at 250MB/s for SATA 6Gb/s (600MB/s) interface. With SATA 3Gb/s (300MB/s) I would have expected only 250MB/s reads and 125MB/s writes.

They are included in the buyer's guide of the following sites.

http://anandtech.com/show/7545/best-ssds-holiday-2013
http://www.tomshardware.com/reviews/ssd-recommendation-benchmark,3269-2.html
http://thewirecutter.com/reviews/the-best-ssds/
http://www.techradar.com/news/computing-components/storage/9-solid-state-superstars-which-is-best-for-you--1190457/2#articleContent

I could have gone with a SanDisk Extreme II, Seagate 600 & OCZ Vector 150 but I honestly would not notice a 10% or less difference in read speeds. Also my writes tend to revolve around UDMA 7 CF card memory transfers and the spec is capped at 167MB/s.

I'm also coming from a 2012 iMac with Fusion Drive and before that I was using mostly mainstream HDD spinning at 7200RPM, 5900RPM, 5400RPM and even 5200RPM.

I know Macbook Pro notebooks made from 2006-Early 2008 are SATA 1.5Gb/s (150MB/s). What's your SSD by chance? If you are comparing a Mac Pro tower then all of them from the 2006-2012 models are SATA 3Gb/s (300MB/s).

Also are you comparing your single platter 1TB Seagate Barracuda to a notebook HDD? Are you using a 3.5" Desktop SSHD?.

The only instance a HDD like the 5x800GB platter 4TB WD Black HDD WD4003FZEX's 186GB/s sequential read/wrrite was outdone was with a Hybrid HDD like the 2TB Seagate Desktop SSHD at 194MB/s.

Yeah, it's true that people won't notice any difference. Almost all of the noticeable differences in speed occur down below the 100MB/s range where hundreds or even thousands of transfers happen per second. Large transfers are of course faster when they are faster but typically a person doesn't notice the difference between 3s and 2.5s

I just expected higher numbers and was wondering why they weren't there. I think it's a mistake to think that half the interface speed will incur half device speeds tho. For example if a device delivers 400MB/s over SATA3 then you should expect it to deliver the full 300MB/s over SATA2.

Sarsfield,
I get 550MB/s read and 450MB/s write from my 840Pro series SSDs over SATA3.

In fact in the buyer's guide on Anandtech explicitly states that to not overspend on high end (I assume performance) SSDs unless I need the extra performance. For an average user put the money to other things or a larger capacity. What is important is that I'm going all SSD since last year.

Based on what I've read it appears that is how some SSDs work. If the bench result is better than what I was expecting the better, right?

Now if there is an SSD that delivers more than 150MB/s, 300MB/s & 600MB/s on a SATA 1.5Gb/s, 3Gb/s and 6Gb/s for all the tests then I'd be inclined to pay a premium that is double of the M500.

Sarsfield,

Samsung 840 Pro is known for that. That was my SSD of choice 12 months ago but the purchase didnt push through as my priorities changed.

Now, I am considering upgrade my SATA 1.5Gb/s and 6Gb/s MacBook Pros as well with the Crucial. At first I feel "cheated" that my max throughput would be capped at only 150MB/s but the response time is still way better than any SSHD or HDD.

Now this bring me to 3.5-inch Desktop SSHDs. It looks like an interesting solution for iMacs with a SATA 3Gb/s interface.

Sarsfield, I get 550MB/s read and 450MB/s write from my 840Pro series SSDs over SATA3.

I'm not doubting you, I'd just like to see it. You could use any number of free speed tests to prove it. My brand new 750 gb 840 EVO maxes out at 540/520 which confirms Tom's hardware tests here:

http://www.tomshardware.com/reviews/samsung-840-evo-review-1tb-ssd,3567.html

There are very few others on the market that actually reach the speeds the manufacturers claim but Samsung has done a great job of telling you real numbers and not fictitious speeds.

sarsfield looking at http://ssd.userbenchmark.com/ Bifurcator may be correct.

250GB 840 Evo vs 256GB 840 Pro
Read: 477MB/s vs 524MB/s
Write: 494MB/s vs 505MB/s
Eff Spd 551MB/s vs 579MB/s
Age: 7 months vs 16 months

If I had to rebuy my SSD I might have gone with 250GB 840 Evo over the 240GB M500. Peso/GB is 35.20/GB vs 29.17/GB respectively.

If you're buying an ssd for external use then watch out for the power draw. I have two sandisk ssds that want 1.6A from a 0.9A usb 3 port. They give me 20-30 MB/s. When an external power supply is used I get up to about 200MB/s. Nowhere near as fast as I expected nor indeed as fast as I got from thunderbolt on a Mac system.

Did you try reformatting the drive ? Or simply deleting all files ? After that try a low-level test that looks for bad secotors, etc. If none are found then the drive ought to be ok, but check the SMART data to be sure. Otherwise it is unsafe and therefore completely useless even for trivial data. A drive that cannot be trusted should be used for target practice. Don't give it away and don't throw it away just in case someone gets your data off it.
