Hard disk lockup.
So I've recently had a couple of random freezes on the hard disk, which caused some unresponsiveness in the system (couldn't open files, shutdown, etc).
I had related issues in Windows 7 as well, but installing Intel Rapid Storage Technology solved the problem almost 100%.
Now I'm not sure if I should install this service in Arch, since it's mostly needed for Raid which I don't have, but the manual of the laptop (Clevo p150hm) suggested I do so anyway (for Windows that is).
I ran fsck, but there were no errors whatsoever. Same thing with smartctl.
dmesg output after the freeze:
FileThre: Cannot read block bitmap - block_group = 1, block_bitmap = 1026

Before that section, there was a gap for some reason - don't know what that means. And of course after booting again, there was a recovering journal process, which ended successfully the first time, but the second I had to boot to Windows, then reboot, because some process failed and eventually led to an emergency shell.
Ok, now I get some unresponsiveness on certain things (can't open app menu in xfce-panel, keyboard scrolling in chrome, right click in desktop - although the launchers in the panels work good, except that when launched the terminal becomes unresponsive). After a while the system becomes fully functional again.
dmesg:
[ 1963.822517] EXT4-fs (sda3): re-mounted. Opts: commit=600
[ 1969.130092] EXT4-fs (sda3): re-mounted. Opts: commit=0
I don't know if it's related to the 2 disk lockups I had. Could some file have become corrupted, so the remounting is a failsafe thing of the OS?
I also seem to have noticed that it happens when I play a media file, and I have to use the fn-buttons to increase/decrease the volume. But the log kinda baffles me.
edit. Well, it happened again. (see 1st post)
Again I had to boot to windows, in order to boot to linux, otherwise it stated that "failed command: FLUSH CACHE EXT", (or something like that) when it was recovering the journal.
At the time of the freeze, the dmesg was similar to the one I posted in my opening post. And if I remember correctly, they were the same sectors (wtf).
I just want to locate the fault for certain, before I just replace the hdd and then maybe it happens again.

Zen Micro Lockup - Hard disk failu
Zen Micro froze while playing an MP3 file. Had to remove battery to reboot. Can hear the hard disk seeking ~25 times during powerup before it freezes at the "CREATIVE" logo screen. Rescue mode commands - reformat/reboot/disk clean up has no effect. Can't hear any hard disk activity when unit held close to ear.
Firmware version is v0.0.56. Hard disk had ~750KB of free space. Unit was sitting still on desk at time of failure. Used less than 2 weeks.
Aside: Have experienced several lockups with this device during playback and docking. All were resolved by removing battery. Firmware seems to be very buggy.
Already logged a formal e-mail support request. Wonder if anybody has experience similar failures.You do hear of them from time to time. It might be that the heads have jammed, in which case you can try the advice here at your *own risk*.

Wrong support on hard disk failure?
My iMac had been getting progressively slower (applications would lock up with the spinning wheel for minutes at a time before letting me do anything).
After one such lockup, I hard booted and the iMac didn't come back - just stuck at a grey screen with the spinning wheel.
I rang Apple Support and on a long support call was taken through various checks before the conclusion of hard disk problem was diagnosed. We tried to repair using the disk utility, but that was unsuccessful and given that I had a time machine backup, the advice was to reformat, reload Snow Leopard, re-download and upgrade to Lion and the use Time Machine to restore.
All fine (and I am back up and running now) - but one element of the support advice didn't ring true to me and I ignored it! So I'm asking for opinions on whether I was right to do so.
I was told to use a Time Machine backup from before the slow behaviour started, as by restoring I could restore the disk problem in the files loaded back from the Time Machine backup. This made no sense to me. I had a hard disk failure - sure - and Disk Utility confirmed this. By reformatting the hard disk, I've eliminated the hard disk issue (albeit that having failed once I guess I may get other bad sectors/failures in the future). The files on Time Machine - in whatever state they are in, are just files. By copying them back onto the disk, I can't damage the disk - I may just end up with damaged files. If some of those files were operating system files, then I could end up with problems - but as the operating system was cleanly installed - not from Time Machine - then even this shouldn't be an issue.
Seems to me the only issue I may have is with my own files - restored from TM - if they happened to be on a bad part of the disk and were damaged.
Do you agree? Or am I missing something about being able to create bad areas on a disk by copying bad files?To add to this - given that I've had no replies, given with perhaps others have faced similar issues without a solutions.
My problem has recurred - the disk failure repeated - again unable to repair the harddisk and having to reformat, reinstall Lion and restore from Time Machine again.
Two points here:
I continue to believe the support information I was given was wrong - and will be talking support again to test this. My harddisk post reformat was fine (disk utility showed no problems), and post restoring from Time Machine the harddisk again was fine. But after a week, the disk has failed again. I don't believe that restoring files can cause this, but think I must have a bad harddisk and that the real answer is to replace the harddisk
I was told (on the original support call) not to use the latest backup - as that might bring back corrupted files that could recreate the disk problem. I ignored this as above as I felt the support was wrong - it making no sense to me that on a good disk, copying bad files could corrupt the disk. However, when you use the migration assistant you do not get an opportunity to choose the date you are copying data from - so there seems to be no way of doing what the support team told me to do - by default I get the very latest backup. Am I missing something? -
Can't create Aperture vault on my new 1 Terrabyte Hard Disk
Just bought two new Maxtor 1 terrabyte harddisks to back-up my Aperture vault,
my Aperture Library is now about 450 Gb. When I'm making a new vault on the new hard-disk, wich takes several hours, my G5 will "colapse" after a few hours, the whole system is stuck and the only way to get out is too get the power of.
When I restart and look at the disk I see that about 250 GB has been transported, I tried this several times and it's always stuck at about the same point. Also when I'm dragging the Aperture-file to the new disk, the same thing happens.
When I do the same thing to a Maxtor 500 GB disk everything worls fine.
Does anybody have a clue ? Thanks in advance !
With kind regards
Albert BrunstingIt could be that the 1TB drive is heating up and shutting down after turning for several hours causing the system to lockup. Might try adding a cooling fan pointed at the external HD.
One alternative is to reduce the library size. Export projects from that large library into another empty one until both are about equal in size. Then back up each library individually onto the external HD. -
Hard disk starts to run then slows entire system down
My MacBook ran fine until I installed Aperture. Since then, it runs OK for a while, then suddenly will stop operating anywhere from 30 seconds to 5 minutes. The little colored pinwheel will appear and start to run. Sometimes it needs a complete hard reset to begin operating again. During these times, the hard disk runs continuously, and battery consumption increases.
I have totally removed Aperture (using AppZapper) and re-installed several times, all to no avail. At this point the MacBook is unusable as the lockups occur frequently. It seems to be cumulative, it runs OK for longer periods after a reboot and the longer it runs the worse it gets.
While in the locked up state, I can't run any utilities to see what's going on that is causing this problem. I have noticed that the SyncServer (whatever that is) uses a lot of CPU time when the MacBook is operational (ie not locked up).
Any help would be appreciated.
JohnHi
I don't have a definite solution, just a couple of suggestions:
1. Try clearing out all cache files using a utility like Onyx or Leopard Cache cleaner (Google will find them). While you're at it, repair disk permissions, too.
2. If that doesn't help, then try re-installing Leopard using the Archive and Install option. Make sure all your files are backed up first, just in case of snafus...

Hi,
I am using Windows 8.1
I have an External Hard Disk i have partitioned it to 4 parts.
One drive is now inaccessible due to sudden power failure while listening Music from that drive few days ago.
Now it shows "Data error (Cyclic redundancy check)".
I tried all the procedures provided here like
chkdsk /f, diskpart, rescan etc
but no result :( (i mean all processes failed. They could not detect the drive).
Please help me to get those data, pictures and project files.
thank youThen why aren't you posting this in the Windows 8 forums found @

Delete file from hard disk etc.?
Can iTunes do the following, and how?
1. When I ask a file to be deleted from the Library, is there some way of asking for the file to be deleted from the hard disk itself?
2. If the location of the file has changed, can iTunes update its library and delete the unfound files from its list?Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

RE: Apple iMac 27 Hard Disk Replacement Complaint
Dear Customer ServiceManager,
RE: Apple iMac 27” Hard Disk Replacement Complaint
On May 12, 2011, Ibought an iMac 27” for my daughter from your official Hong Kong website (www.apple.com/hk).
I am writing tocomplain about my dissatisfaction of your poorproduct quality, irresponsibleattitude of your customer service, and most importantly my painful experience with your Apple Careservice. I am also very disappointed with how your Apple Care staff made a discriminating comment about your low income Hong Kong customers.
On July 28, 2011, mydaughter received an email from your company ([email protected]) informing her that the hard disk of her newly purchased iMac wasdefective due to factory error. You promised to replace the defective hard disk with a brand new onefree of charge, but when she asked your HK Apple technical support if therewould be on-site replacement service, your staff told her that she can onlyeither carry the 30-pound iMac herself to their service center or pay HKD1200for the Apple Care which offers the on-site replacement service.
First of all, I foundyour request very unreasonable. Mydaughter was not the one who broke the hard disk, your company informed herthat you gave her a defective one. So why is the responsibility and the cost of taking the iMac for repairshould be borne by her, as an innocent customer, who paid HKD18, 000 for aniMac directly ordered from your official website? She did nothing wrong but your company required her to barethe cost of transporting a 30-pound iMac and the risk of causing damage on theway.
Secondly, I believeyour company has deceitfully forced my daughter to buy your Apple Care, whichis completely against her original will. Since she is just a 22-year-old girl, it is impossible for her to carrythe 30-pound iMac by herself. Andclearly, she was not given a choice but had to pay HKD1200 for the AppleCare. This made me doubt if thisis a scam of your company. Is thisa way of how Apple make extra money by giving your customer faulty products anda mission impossible, then forcing us to pay for a service that we did notneed?
Anyway, thepainfulness of enjoying your Apple Care service has just started…
On Aug 10, 20111:30pm, your service man came to change her hard disk with just a look as ifthe process was very ‘efficient’ and left after half an hour, even her Mac OShas not yet been completely installed. After he left, my daughter found that the OS could not be installed, soshe called your service center immediately and under her strong request, he hadto come back on the same day and check the new hard disk. He found it proved to be a defectiveone again. I was shockinglysurprised that your company, which always claims to produce products of highquality, selling at an expensive price, replaced my claim-to-be defective harddisk with a defective one again. Iwonder how Apple’s quality control is done? Your company didn’t even bother to check if the new harddisk is working before replacing it for customers.
My daughter requestedfor a new one, but then your service center said they had no new stock andasked her to wait until further notice. But without any definite date, it means my daughter’s brand new computercannot be used for… I don’t know how long. Please notice that I paid HKD18,000 to buy a first-classproduct of high quality, as claimed by your company all over the world.
So my daughter had tocall your service center again and forced them to return her original harddisk. Till 5:00 pm on the sameday, another technician came to reinstall her original hard disk into hercomputer. Surprisingly, all thedata in her original hard disk was still there, which means there is a riskthat all her personal data and information had been accessed by your servicecenter staff.
As a father, I had totake over the matter from my daughter and called your hotline 2112 0099 at5:00pm on Aug 10, 2011. After 30minutes, I could finally talk to one of your technical support staff for 10minutes about my complaint. Heasked me to hold the line and wait for him to transfer my call to his seniortechnical support colleague, so I kept on waiting for 15 minutes, but finallythe line was being cut and no body contacted me and my daughter again.
I had to call yourhotline again at 6:00 pm and waited for another 15 minutes to reach one of youradvisors. He passed my line toyour senior technical support advisor located in Singapore. He said he is just a technical supportadvisor, so he could not take my complaint directly. He needed to talk to meagain on the next day with a customer service advisor. He promised if he could not reach me onmy mobile phone, he would leave his direct line for me so that I would not haveto waste another half an hour to reach him through the hotline.
On Aug 11, 2011 5:28pm, I received a voice mail from your senior technical support advisor asking me to call him back but he didn’t leave any direct telephonenumber as he promised. So I triedto call back the caller ID, which was shown on my phone. However, the auto reply of this numberwas, “This is an invalid number”. I asked the Hong Kong Telephone Company to help me to call but even theycould not reach this number. Theytold me this number was from Shanghai, China. So I had no choice but to call your hotline again. After 25 minutes, one of your advisorstook my call and I had to repeat my story to him again in order to have him putme through to talk to your senior staff 42058 again. I asked him why he didn’t leave his direct number for me tocall him back as he promised. Hesaid he forgot! What a surprisinganswer to leave your customer nothing but a number that he knew clearlycouldn’t be reached.
By that time, I havewasted nearly 45 minutes to reach him, and it was already 6:20pm and thecustomer service advisor was off work. Therefore, I made an appointment with him again and we agreed that hewould call me between 9:31-10:00am on Aug 12, 2011 morning. I took half day-off from my work towait for your senior staff to call me.
Unfortunately, Iwaited until 10:10 am and nobody contacted me again (I left both my mobilenumber and email to them).
Finally, I called the hotline again and waited for 15 minutes, an advisor put me to your on-dutyCustomer Service Manager, Ken. After I told him my name, he realized that he should be theone responsible for calling me this morning, but since he had a meeting thatmorning, he forgot to call me again! The Apple staff didn’t keep their promises after all which disappointedme a lot. It seems to me thatApple is unwilling to accept negative feedbacks from customers.
Ken told me thatthere was nothing he could do.
At the end, I wasreferred to a Customer Relations staff, Ms. Wing Liu. Her response was also there is nothing she can do exceptgiving me a case number of my complaint. Since then, I never get any response from Apple regarding my case.
I believe Apple has afull record of all my conversations with your staff and thus, should be able tolook into my case thoroughly. Isincerely hope that Apple can take my feedback seriously and respond to my complaintin a responsible manner, but not just trying to suppress your customers, whohave already been treated unfairly, from claiming their rights. Otherwise, it is really a shamefor Apple to claim itself delivering high quality products and services allover the world.
Yours truly,
Tommy Fong
Apple Customer
<Personal Information Edited by Host>I just realize Apple might have blocked my daughter's Apple ID from posting in your discussion forum.
My daughter was trying to go to this Community Page by logging into her account. But your Communities webpage displays a "We'll be back soon" webpage. Then I try to login with my Apple account and it works fine.

Toshiba Satellite L650-07U, Hard disk failure and replacement
Hi all,
I have Toshiba Satellite L650-07U Laptop, Model: PSK1EC-0700Q with 4GB RAM, 650GB HD, Windows 7 Home Premium installed. At the time of first use, i made Recovery DVDs which took 4 blank DVDs using Recovery media creator.
From 2 weeks it is giving problem, at start its slowdown with every application, then suddenly it started Hard disk failure error and ask to backup important files. From that instant i did all my backup save in another portable Hard drive.
I had hiren boot CD, and ran RAM test and found it OK, and then run Hard Disk test and found few bad sectors at few certain point, As 650GB Hard disk was taking alot time of time for checking bad sectors, so i stopped that application.
First I tried Recovery DVDs to restore Windows, but it failed as Laptop DVD-Writer was unable to boot from those created DVDs (DVDs are OK as had checked it on Desktop computer DVD-ROM), Laptop DVD-Writer is also working as I test few more bootable CDs and it booted perfectly, but it is not booting from Recovery DVDs.
Than i tried to restore from Recovery partition using Factory restore settings, it erases all data and reinstall new and fresh copy of Windows 7 Home Premium. It works fine for few hours than again pops up Hard Disk Failure message again and again. I searched here in Toshiba Forum and have found similar problem with other members and finally decided that it need to replace Hard Disk with new one. As It is now two and a half month old, thats why i need to buy new Hard Disk for my Laptop.
I checked all partitions of drive using Hiren Boot CD, and had found that there are four default partitions in Toshiba original laptop drive,
One hidden partition of 1.5 GB
One hidden partition of almost 21 GB
One hidden partition of almost 12 GB
One partition of 561 GB, which was the original partition where windows 7 was installed along with all of my Data.
Now I want to replace faulty drive with a new one and have a lot of question in my mind which I need to share with you guys.
At the time of first use I installed Windows 7 64 bit edition, and made Recovery DVDs, and at second time of restore to factory setting I had installed Windows 7 32 bit. I have confusion about recovery DVDs (which is not booting from default DVD-Writer of Laptop), either it has 64 Bit recovery data or 32 bit? Or have both 64 and 32 bit Data.
Toshiba restore to factory setting without using any recovery DVD/USB is the best possible way to restore Windows 7, How can I make same recover hidden partitions from original/faulty hard drives to new hard drive partitions? Is this possible and how?
On Default hard drive there was one partition of 561GB instead of two or more partitions. Is this possible to split partitions in new hard drives instead of one big partition?
As Recovery DVDs are not able to boot from laptop default DVD-Writer, is it possible to open those DVDs on another System and copy tem in USB drive and use it for booting? If it is possible than please show me the steps for making bootable USB from these Recovery DVDs.
Thanks,
masterleous
Solved!
Go to Solution.Satellite L650-07U (PSK1EC-07U00Q)
This site is for US computers. I doubt you'll get your questions for that Canadian model answered here.
There appear to be two recovery partitions. Maybe one for 32- and one for 64-bit Windows. Or maybe one is for English and the other for French.
Your User's Manual isn't much help either. You probably need to ask Toshiba tech support in Canada.
About all I have to offer is this: Be wary of drives with advanced-format technology. See my message about that.

Hard disk not detected once, but now working?
Hi,
I'm Zak, a bit of techie when it comes to playing with software, or re-assembling computers and whatnot. Unfortunately I've got no clue about some other things.
A bit of quick history on my notebook: The fan has been making terrible noises the last few weeks. Initially I thought it was some dust so I got some duster. A lot of dust came out, so that can only be good, but the noises came back after a few days. After some searching I figured the other logical explanation was probably the hard drive going bad. I'm hesitant to send it back to HP because I use it for all my university work and it would really set me back a few weeks to not have it.
So, a few days ago, I booted up my notebook to a "hard drive not detected" - or very similar - message. There were a few options, for f1-f4, they were system information, and 3 different tests (I think). I ran the tests, each one came back fine, noting that there was no OS installed, or hard disk to boot from. I rebooted because I hadn't quite seen it boot up, and wanted to see if there were any other options. Turns out, it started up fine. I restarted once more and again, it did fine.
Next, I scrambled around, backing up all my data, getting together warranty info, installing the HP Support Assistant, etc. I ran all the tests from the Support Assistant and there were no problems detected. Since then I've just been hibernating the notebook when I stop using it, and I haven't encountered any unusual trouble. It all seems fine, but my warranty expires Dec 7th of this year. Is it safe for me to assume the "hard drive not detected" error was just a single misfire? I've read a lot of threads and FAQs on it and it doesn't sound like something that just happens once and goes away. On the other hand, I've never had to use a warranty so am unsure quite how the process works, and like I said, sending it anywhere would put me back in my work.
For the sake of a full post, I have an HP G62-367DX Notebook, running on Windows 7 64-bit OS, and as far as I know there were no changes made between the error and my prior boot. If there's any other information I can provide, just let me know.
Cheers, thank you very much for any assistance, and good day
This question was solved.
View Solution.The tests from the Assistant are not as comprehensive or reliable as the full hard drive test in the BIOS....tap F10 as you power up, go in there and find the hard drive test. Run the long form test and see what is says. It is not unusual for hard drive issues to start as intermittent and gradually get more frequent. If your drive passes the long form test you can fairly safely assume it was a one-time gremlin of some sort, but it is still a real good idea to back up. I like the idea of the online backup services and I will name Carbonite only because it is well known and not as an endorsement. There are several more and an external drive is also a good idea.
You cannot put off a reboot forever; you are going to have to confront the issue at some point. -
IMac doesn't recognise the internal hard disk (intermittent)
Hi, I was wondering if anyone could give me an advice on this problem.
Background: A few days ago my iMac (20-inch MA877LL) would not boot up, it would sit on the gray screen with the wheel spinning for ever. I thought the OS might have got corrupted so I tried to re-install Snow Leopard from the CD. Installation fails with a message like 'the content of HD can not be changed'. I then went to Disk Utilities trying to repair the disk but had no luck with the repair so I decided to format the disk. I managed to get into my hard disk using the cmd R key combination at power up and backed up my essential files onto a external hard disk. I formatted/erase the hard disk (zeroed out) and tried to reinstall the Snow Leopard again. The installation failed again. Rebooted the system again and tried to re instal again but this time I got as far as the 'select the disk where you want to install Mac OS' but my Hard Disk is not listed, it's a blank list! Rebooted the maching again, tried the installation, this time it sees the hard disk but the installation fails again.
I have tried to change the boot source by hodling the 'alt' key down at power up, but I am only given the option of the CD drive with installation disk as the boot source i.e. no Har Disk. It appears that the Hard Disk is intermittently recognised and hence my problem with booting the maching when the problem started.
I am happy to purchase an internal disk to replace the existing one, but I have a feeling the actual Disk it's OK, after all I managed to access my data to back up and then format it with no problem. I just think there's a problem somewhere that intemittently doesn't recognise the Hard Disk.
Any suggestions will be much appreciated.You need to have the hard drive replaced. The one that is currently installed has failed.

Comparison of SSD with hard disk drives
Attribute or characteristic
Solid-state drive
Hard disk drive
Spin-up time
Instantaneous.
May take several seconds. With a large number of drives, spin-up may need to be staggered to limit total power drawn.
Random access time[45]
About 0.1 ms - many times faster than HDDs because data is accessed directly from the flash memory
Ranges from 5–10 ms due to the need to move the heads and wait for the data to rotate under the read/write head
Read latency time[46]
Generally low because the data can be read directly from any location; In applications where hard disk seeks are the limiting factor, this results in faster boot and application launch times (see Amdahl's law).[47]
Generally high since the mechanical components require additional time to get aligned
Consistent read performance[48]
Read performance does not change based on where data is stored on an SSD
If data is written in a fragmented way, reading back the data will have varying response times
Defragmentation
SSDs do not benefit from defragmentation because there is little benefit to reading data sequentially and any defragmentation process adds additional writes on the NAND flash that already have a limited cycle life.[49][50]
HDDs may require defragmentation after continued operations or erasing and writing data, especially involving large files or where the disk space becomes low. [51]
Acoustic levels
SSDs have no moving parts and make no sound
HDDs have moving parts (heads, spindle motor) and have varying levels of sound depending upon model
Mechanical reliability
A lack of moving parts virtually eliminates mechanical breakdowns
HDDs have many moving parts that are all subject to failure over time
Susceptibility toenvironmental factors[47][52][53]
No flying heads or rotating platters to fail as a result of shock, altitude, or vibration
The flying heads and rotating platters are generally susceptible to shock, altitude, and vibration
Magneticsusceptibility[citation needed]
No impact on flash memory
Magnets or magnetic surges can alter data on the media
Weight and size[52]
The weight of flash memory and the circuit board material are very light compared to HDDs
Higher performing HDDs require heavier components than laptop HDDs that are light, but not as light as SSDs
Parallel operation[citation needed]
Some flash controllers can have multiple flash chips reading and writing different data simultaneously
HDDs have multiple heads (one per platter) but they are connected, and share one positioning motor.
Write longevity
Solid state drives that use flash memory have a limited number of writes over the life of the drive.[54][55][56][57] SSDs based on DRAM do not have a limited number of writes.
Magnetic media do not have a limited number of writes.
Software encryption limitations
NAND flash memory cannot be overwritten, but has to be rewritten to previously erased blocks. If a software encryption program encrypts data already on the SSD, the overwritten data is still unsecured, unencrypted, and accessible (drive-based hardware encryption does not have this problem). Also data cannot be securely erased by overwriting the original file without special "Secure Erase" procedures built into the drive.[58]
HDDs can overwrite data directly on the drive in any particular sector.
Cost
As of October 2010, NAND flash SSDs cost about (US)$1.40–2.00 per GB
As of October 2010, HDDs cost about (US)$0.10/GB for 3.5 in and $0.20/GB for 2.5 in drives
Storage capacity
As of October 2010, SSDs come in different sizes up to 2TB but are typically 512GB or less[59]
As of October 2010, HDDs are typically 2-3TB or less
Read/write performance symmetry
Less expensive SSDs typically have write speeds significantly lower than their read speeds. Higher performing SSDs and those from particular manufacturers have a balanced read and write speed.[citation needed]
HDDs generally have symmetrical read and write speeds
Free block availability andTRIM
SSD write performance is significantly impacted by the availability of free, programmable blocks. Previously written data blocks that are no longer in use can be reclaimed by TRIM; however, even with TRIM, fewer free, programmable blocks translates into reduced performance.[25][60][61]
HDDs are not affected by free blocks or the operation (or lack) of the TRIM command
Power consumption
High performance flash-based SSDs generally require 1/2 to 1/3 the power of HDDs; High performance DRAM SSDs generally require as much power as HDDs and consume power when the rest of the system is shut down.[62][63]
High performance HDDs generally require between 12-18 watts; drives designed for notebook computers are typically 2 watts.I wish I could get my head round the SSD vs HDD with a NLE rig. My builder is trying to persuade me to use a Toshiba 256Gb THNSNC256GBSJ for OS and programs, and it is only NZ$20 more expensive than the 450Gb 10k rpm VelociRaptor I was originally planing to use for the OS. That sounds suspiciously cheap to me, and I am concerned about the finite writes to SSD - mainly because I don't really understand it.
The rest of the new build is
3930K
Gigabyte X79-UD5
8 x DDR3 1600
Coolermaster with 750W PSU
Geforce GTX570
I plan to transfer the drives from my current system as a starting point, and reassess after giving it some use. That means
Either the above SSD or 450Gb 10k Raptor for OS (new drives)
300Gb 10k rpm Raptor (currently used for OS in old box)
150Gb 7k4 rpm Raptor (reserved for Photoshop Scratch in old box)
2 x 1Tb WD Blacks (data drives)
2 x 1Tb WD USB3 externals
I don't know how I would configure the drives in the new box, but have seen Harm's table and will try to follow his advice. It's a dreadful thing to admit, but I don't have a backup strategy, and the above drives are well over half full. Well over! And I am only just getting serious about video, (the rest is mainly CR2 files from my Canon 1Ds3 and 1D4)
I know it must be like banging your head against the wall, but should I avoid that SSD and go with the 450G Raptor? I have read a comment that the WD Blacks don't work well as Raid0. Is that BS or true?
I am about to give the go-ahead so need to confirm the spec. -
Pavilion G6-1203ey: Hard Disk Test FAILED, but can still boot into Windows
Hello
I have HP Pavilion G6-1203ey laptop. After installing Windows (7 ultimate, 64 bit) and some drivers on it and after several restarts, it hanged at Windows logo and I had to turn it off with power button. Then after turning it on, it gave me the option to repair problems which are preventing it from starting up, from there I let it to restore the computer to an earlier restore point and after a restart the Windows was working again. After that I decided to do a hard disk check just in case.
The Hard Disk Self Test ended up with a message: Hard Disk 1 Full (305). Then I installed HP Unified Extensible Firmware Interface (UEFI) Support Environment and did hard disk from there. I chose the comprehensive test from the options, but it finished fairly quickly (in ~1 minute) with the following output:
Testing Drive: 1
Hard Disk SMART Check : PASSED
Hard Disk Short DST : FAILED
FAILURE ID : PTTU22-5T774L-MFPV4K-60S003
PRODUCT ID : A5Q15EA#B1R
Hard Disk 1
Hard Disk Test : FAILED
A bit more background:
The previous owner told me that the original HDD was faulty which is why he replaced it with this one last year. He said that other than that there has been no problems with the laptop. The Windows is working right now and this HDD is quite new so I would not have expected any problems with it, but the results from the previously mentioned tests seem troubling. Is there a reason to worry?
Thanks
This question was solved.

Welcome to the HP Support Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I read your post and looked into the failure ID that you posted regarding the failed Short DST test. That error is indicating a hard disk failure meaning that if it hasn't failed it might soon. If everything is working I would considering backing up your data on a regular basis just to be safe. You could have a local technician take a look at the hard drive to see how close it is to full failure.

Disk write cache corruption on an external hard disk
Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.
Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..
This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.
I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.
On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.
I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.
I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.Disabling a write cache would not help you with the problem you are having. Besides the write cache is on the hard drive and operates independently of the operating system. But nothing can protect you from disconnected an external drive improperly, and if the drive is in the process of being written to, and the problem comes from directory corruption, not file corruption, as in the case you have described, disabling a write cache would not have made any difference.
For the future the magic word is: Backups.

This external hard disk used to serve as the main drive of my mbp. It got corrupted and the OSX would no longer load. I upgraded to a 500gb hd and used the old hd as an external drive. I tried to copy my files but i could not access them because of the filevault encryption. 110gb of hd space appears as used which means that my files are still in the drive. Is there a way to retrieve these files? thanks
According to your post, you're using Leopard, so FileVault only encrypts your user folder (unlike Lion). On the mounted external drive, in your user folder, you should see a file called username.sparsebundle, with username being your user name. Double-click that file to open it and it should prompt you for a password. Type in your password and the file will mount as a volume in Finder. You should be able to copy all of your files over.

Choosing the proper port when creating email accounts.
Comcast wants us to use 587. But that created some problems for me. Mail prefers 995. My email boxes were always offline and refused to go online when I am using 587 but 995 they love it. Do I have to open port 587 somewhere? Thanks in advance.
