RAID 1 member drives failing repeatedly on 2 different systems

I have had the same issue with 2 systems now. The first was a Dell desktop with 2 drives set up as a RAID 1 array, and the current system is a white-box with 2 RAID 1 arrays. Periodically, one of the drives will report as failed; I mark the drive as normal
and it rebuilds, A few days/weeks/months later I get another failure, sometimes on the same drive, other times on a different drive. In the case of the Dell, I replaced both drives 3 times and the RAID controller once and never got rid of the problem.
The new system ran fine for about 6 months, and now I've had a particular drive fail twice in 3 days, and now a drive on the other array died 4 days later, followed by the array holding the OS showing as unavailable while attempting to rebuild again when
the same problem drive seemed to fail.
Both systems are currently running Windows 7 Ultimate. The Dell is running 32bit, and the white-box is running 64bit. Both are using Intel SATA RAID controllers and both systems are using WD HDD's.
The fact that I've had 2 systems with the same issue is starting to make me think that it's not hardware failures, and I am wondering if there's are any common applications or environments that are known to induce errors like this.
One of Dell's tech support people stated that I was wearing the drives out by not turning the system off when I was not using it. Somehow I don't think that's an issue.

Hi,
I would like to verify what error message you received about the drive failure. Please ensure you have loaded the properly RAID driver. As Dell tech support mentioned,
I suggest you turn off the system when you are not using it.
If the persists, I think it should be hardware issue, it is better to contact the HDD manufactur to exaimine.
Best Regards,

My G-Raid hard drive fails back up

I have a Mac Book Pro OS X 10.5.8
2.4 GHz Intel Core 2 duo 2GB 667 MHz DDR2 SDRAM
I have a G Technology 2 TB and have 991GB left on it. I want to back up my computer (165 GB) to the G Raid with 800 Firewire.
The problem is every time I start the back up only gets to about 35% done and then an error occurs. It fails the back up and quits.
Please Help, my computer is getting old and I really need to get it backed up.

What are you using to create your backup? Time Machine? Cloning software? What?

Export client to hard drive to move to a different system

Sorry if this is the wrong forum to post this as I am fairly new to the forums.
We have 2 SAP servers one in the US and one in Germany.
We are getting rid of the SAP server in the us because the lease is due on this server.
We have one client system that I need to export from this US server to send to the folks in Germany to import as a new client.
But I am sort of stuck as this is a totally different SAP server. I tried to use transaction code SCC8 but it looks like that exports to an existing system within the server? Is there a way to export a client out to a hard drive so I can then move the files to a dvd and send them via mail to germany?
Does SCC8 only work to export a client on the existing system???

If its done via export then is basically a huge transport... as long as both versions of SAP are the same and patch at the same level you should be ok.
but I am sort of stuck as this is a totally different SAP server.
Can you be more specific?... as I said before they need to be the same version, same patch level.
there a way to export a client out to a hard drive so I can then move the files to a dvd and send them via mail to germany?
Depending on the profile used SCC8 will create 2 or 3 files... I wouldn't use DVD's but you can definitevely store the data in a external drive or backup tapes.
If the systems are different versions and you need to install a new box in germany you will be better off creating a dump using sapinst. If the target OS/DB is different you'll need to follow the heterogenous system copy guide otherwise Homogeneous system copy will do.
Does SCC8 only work to export a client on the existing system???
No, you can use SCC8 to export to other systems

Software raid 1 drive(s) failed

Curious on what to do with a RAID 1 Drive (s) failure? I've searched the community and cannot find similar issue/answers.
Configuration:
One 1TB OS & App Drive is fine
Two 3TB RAID 1 Drives for Video scratch are fine
Two 2TB RAID 1 Data Drives are my issue
I'm using the software raid in OSX and it shows "2TB Data Drive/Mirrored Offline"
Both drives have "Failed" next to them
I have backup this Data Drive in Time Machine and a recent full back up to a single drive that is off site. I believe I have a good back up strategy with Time Machine and offsite back ups via Voyager S3. I guess we'll find out!
My question is how do I find out if it's a HW issue or SW issue with this configuration ? And then how to go about recovering them?
Initially when I looked in Disk Utility it appeared that only one of the 2TB drives had "Failed" next to it but now after a reboot "Failed" is next to both drives.
My initial hope was that one of the drives had failed and I'd be able to just replace that drive and the RAID System would rebuild from the other drive.
Any assistance would be appreciated.
Thanks

RAID 1 just copies the same data to two (or more) drives at the same time, it's only for mission critical data loss requirements where a drive failure during writing would be catastrophic. Like taking purchasing orders or getting a phone call from ET for example.
RAID 0 is dangerous as the data path is separated to how many drives in the RAID 0 set, one drive glitches and all data is lost. But provides insane speeds.
RAID 5 is a much more reliable, it combines many drives (4 or more for more speed) splitting the data path but also has redundancy factor that if a drive dies it can be replaced and the data is recovered from the other drives. Usually a RAID 5 is in a external enclosure with it's own cooling and hardware controllers, not software based RAID where your CPU is being overloaded.
There are other forms of RAID some combinations like RAID 1+0, RAID 6, 10 and so forth, you can find out more about the more eclectic RAID types online.
RAID 5 is more ideally suited to video requirements for data storage, with perhaps a RAID 0 as a scratch disk or a RAID 0 + 1 (the RAID 0 is mirrored to another RAID 0) if your going to take a while working on it that increases the potential of failure.
Once the work is completed, it's sent to the RAID 5 where it's safe with it's redundancy and speed.
http://eshop.macsales.com/shop/hard-drives/RAID/Desktop
The thing to remmeber with the failed RAID 1 Data drive is the data is still on the drive, even though it failed and perhaps things are messed up a little on it on the directory. All the drive needs is to be told it's not part of a RAID 1 anymore, that it's a normal drive, a simple fix, but I don't know how to go about it.
You have two drives and two chances to recover the data off off, simply disconnect one data drive and reboot, see if it will mount and or you can repair the drive in Disk Utility.
If not pull one drive out and stick another blank one in there and download Data Rescue and simply recover the files to the new blank drive. DR works by simply reading the files themselve, not the file struture or anything else.
Software RAID is unreliable, it depends upon the CPU. Opt to get a external RAID where it's based in hardware instead. Use eSATA if all possible.
Also consider using backup software, like Carbon Copy Cloner which can be scheduled to make a backup of your data during the middle of the night. This way if something happens to either your boot drive or a data drive, the clone won't immediately copy the issue to the other drive like a RAID 1 does.
Also Carbon Copy Cloner makes "hold option" bootable OS X boot drive clones, which TimeMachine doesn't.
Also TM kicks in what, like once a hour? It's likely what caused your issue, CCC will work when you schedule it. TM is for consumers, not video pro's like yourself.
If you need even heavier iron as a external RAID setup and more expertise, then see these guys

What happens in a RAID 50 when a drive fails?

Hey all.
I'm setting up my Xserve RAID and need some advice. Right now it has been populated with 14 drives and set up as two RAID5 arrays. Ideally I would like to software RAID these in Disk Utility to make a RAID50 for the speed increase.
If I were to set up as a RAID50, and then a drive were to fail, what would happen to the RAID? I know that when a drive in a RAID0 fails, there's no parity so your RAID is pretty much gone. I also know that in a RAID5 when a drive fails it can run in a degraded state. I'm just trying to wrap my head around how this translates when you combine the two into a RAID50 and a drive fails. Will half of the data be lost, or will it be fine, just running degraded?

Jeff,
RAID 50 is two RAID 5 arrays striped in a "RAID 0".
Each of the RAID 5 arrays can suffer one hard drive failure, which will cause it to run in degraded mode until the failed drive is replaced and the RAID rebuilt.
Not sure what sort of speed you're looking at, but RAID 30 provides significantly better performance with video and large files.

IMovie -Problem restoring events after external hard drive failed.

iMovie 09 – The external hard drive failed where I stored my 2012 events. I do not have a backup copy of these events. I bought a new external drive and named it exactly the same as the old drive. Then I uploaded archived original video clips to it recreating the events. I used the exact same event names. However when I view the projects I made from the original events, I get “this clip’s media file is not currently available”. The file path I created should be the same as the old, so why does the project not recognize the recreated events? Any suggestions what I could try?
If I were able to retrieve and copy the old events from the failed drive to the new drive, would that work?
Has anyone successfully dealt with this problem?

That's a very interesting scenario that you've described. I've been concerned about a potential situation arising where I may need to restore Events from a backup drive. However, your situation is somewhat different in that you've had to re-import the Events to a new drive from an archive.
My main video drive is a Maxtor One Touch III Turbo comprising two 500GB drives set up as a RAID 0. So, effectively it appears as one drive totalling 1TB, with data being written to both drives simultaneously (but not mirrored). However, if one drive fails, the other becomes ineffective as it contains only partial data about imported clips (the remaining data being on the failed drive).
I backup the Maxtor to a portable 1TB drive by cloning it using SuperDuper. My thinking has been that, if the Maxtor fails then a simple rename of the backup drive to the same name as the Maxtor is all that will be required for iMovie to retain the linkages between Events and Projects. I hope this is the case!
I hope you get a solution to your predicament - sorry I can't offer any useful advice!

Macbook Pro Hard Drives Failing

Hi all,
I've been having massing problems with my Macbook Pro 15" 2.53 Ghz laptop. I got one brand new with apple care in December of 2008. The hard drive was the standard 320 Gb @ 5400 RPM.
Within approximately two weeks of operation the computer failed (froze and after a hard shutdown wouldn't boot). It turned out the hard drive failed. Two weeks! So I took it back to Apple and they replaced the hard drive (took them one week so I lost a week of productivity).
One week after receiving the laptop back, the hard drive failed again! This time I believe the OS got corrupted somehow as the symptom was that it would not boot.
So back to Apple and they straight out replaced it with a new one. One week later, guess what? Failure. So back again and they replaced it.
I'm now on my 3rd laptop from Apple and this hard drive is failing. Luckily I was able to back everything up. I downloaded a utility called SMART Utility and it tells me 60 some sectors are bad on this disk.
Is anyone else having issues like this? Its absolutely ridiculous. Currently the computer is working despite the failed sectors and horrible sounds coming from the hard drive but I expect failure soon. I'll be taking this back to Apple and showing them the results of the SMART Utility, but I'm at the end of the rope here.
I've owned multiple Macbook Pros before and absolutely loved them. But now I am so disillusioned by this... To Apple's credit they have had great customer service, but now I'm at the point where I need to be able to rely on my machine.
Has anyone heard anything?

I would second Michael's comment. While hard drives do fail, the rate at which yours are failing would appear to be well beyond the statistical average. I would generally think the next level would be a problem with the MacBook itself causing the failures, but from what I can tell from your comment is that they have replaced your MacBook twice (and you're on your third?). So that would seem to rule out a problem with the MacBook itself. You mentioned that you've had other MacBooks before and it doesn't sound like you've had problems with them... so I wouldn't expect that you're doing anything unusual that would cause the problem.
You're either had a remarkable run of bad luck, or there's something going on that's out of the ordinary causing these drives to fail. I would imagine that when stores get machines, they're likely shipped from batches that are manufactured at similar times. If they had a batch of faulty drives from the manufacturer, it's possible a single store could have gotten several of them. That would still not really explain why your initially replaced drive failed as it would likely have come from a totally different batch than what would have been used in manufacturing at the time your notebook was put together. I guess it's always possible that they might put in a drive that that wasn't new.

T61 DVD/CD-RW drive fails to read and crashes

Hello Everyone, I hope people still visit this area of the forums!
I've highlighted and bolded the symptoms to make them easier to find.
I recently purchased a T61 6457-C15 on eBay, and have been in the proccess of setting up and customizing it to suit my tastes. When I recieved the laptop, it looked as though Windows had been restored to original factory state, plus some free software, so I proceeded under that assumption. First I used Windows Update to download all the updates that it could find including IE8. I wanted to have an anti-virus program running on my computer before I used a browser to access the internet. I ran IE8 and went straight to the Microsoft Security Essentials website and downloaded the Install program. At this point I tried to remove the pre-installed and expired Norton Internet Security using the built-in uninstall, but it failed. A message box popped saying that I needed to put the Norton installation disc in the CD-ROM drive so that the uninstall program could find a Norton support file. My computer did not come with any discs, but my mothe had bought Norton 2008, so I took that disc and put it in the drive. The drive started spinning right away, and the uninstall program found the file it was looking for in a few seconds. The support file directed me to the Norton website to get their removal tool, which removed Norton from my system in short order. Afterwards, I ran the Microsoft Security Essentials install program and got MSE running on my computer before doing anything else.
Then I went to the Lenovo support website and had it auto-detect my system. That took me to the support page for my system, where I went to the "Downloads and Drivers" page. I downloaded Access Connections and ThinkVantage Toolbox for Vista 32-bit (my OS is Vista Business 32-bit). I then used Lenovo System Update to retrieve all the updates it deemed neccessary from Lenovo, including those for itself and system components, both software and firmware. There were 35 or more updates suggested, and I trusted the software, so I started downloading them all. I'm not sure, but I think that a DVD/CD-RW drive update was included in the list, but I can't remember if it was auxiliary software, drivers or firmware. After Lenovo System Update was convinced that it had all the neccessary updates, I downloaded Revo Uninstaller and set about removing uneccassary and unwanted programs from my computer and trimming the startup list. I did not touch any Windows or ThinkVantage components, and I searched each program online, so I'm sure that I did not delete or disable any drivers or system files, or anything from Lenovo. I mainly removed Apple products and non-functional software from my system, including an integrated camera driver (my system does not have an integrated camera) and third-party programs that were already missing files or otherwise inoperable when I got my computer. Up to this point I had been using a gigabit ethernet connection to download software; I had not used the DVD/CD-RW drive except for the one time I specified earlier.
Now that I had my system set up to my liking, including personalization and power settings, I started to install my first program: Command & Conquer the First Decade from a DVD-ROM. When I put the disc in the drive and closed it, it took a few seconds for the drive to spin up, and once it did, it was constantly running at high speed and I could hear the reader constantly moving back and forth quickly. After a few minutes the disc's install menu finally appeared, so I clicked on the install button. I waited several minutes but nothing happened, so I tried to view the contents of the drive by going to My Computer > DVD/CD-RW drive (D, right clicking and selecting explore from the menu options. When I did that, the address bar of the My Computer window started to fill up with a dark gray progress bar and said "loading (D", I think with the drive or disc name after it. After it took several minutes to fill completely, nothing happened. I waited a few more minutes to see if anything would change, (nothing did,) I clicked on the X button in the top right corner of the window to close it. A few minutes and clicks later, the My Computer window was labeled as (not responding), and the window itself became grayed-out. I started Task Manager and tried to close the My Computer window, but the entire Windows Desktop disappeared along with it, saying that it would attempt to restart. Even Task Manager became non-responsive and quit after closing My Computer. After a few minutes of staring at my background (and nothing else), I ejected the disc, and Windows Desktop reappeared immediately and acted as if nothing had ever been wrong.
I checked Device Manager, but neither the DVD/CD-RW drive nor any of the ATA controllers were flagged; in fact they all said they were working properly with up-to-date drivers. I ran the ThinkVantage Toolbox diagnostics on the drive using a data CD, a music CD and a different DVD-ROM, but in each case the drive failed the tests and a message box popped-up saying that the discscould not be read because they were scratched or there was a hardware problem. I checked the discs both before I put them in and after I took them out, and they were not scratched; also, all of the discs are publisher-manufactured from a software or music company. I restarted my computer, booted the Rescue and Recovery option and Ran PC-Doctor from there. I ran the same drive read tests with the same failure results. The entire time the drive was behaving the same way it had when it first failed to read a disc. Next I removed and cleaned the drive both inside and out with a can of compressed air; I also cleaned the ultrabay itself. Finally I tried fixing the problem with Microsoft Fix It, but when it automatically ejected the drive and i put a disc in, the disc became trapped in the drive and Windows froze up like before. I had to restart Windows twice (once with a BSOD) in order to get the disc out. When the disc was removed the computer went back to normal operation once again.
Please help me, my DVD/CD-RW drive is a Matshi ta UJDA775, my operating system is Windows Vista Business and my T61's model number is 6457-C15. I have tried all the troubleshooting fixes and none have worked. I have tried updating drivers and using diagnostic software and they have not worked. I have tried disabling drag-to-disc burning and it has not worked. I have treid removing and cleaning the drive and that has not solved my problem. I did notice that the driver for the "Intel(R) ICH8M-E/M SATA AHCI controller" is the only related driver that can be rolled back, so maybe that might fix it. I'm also wondering if a firmware change caused this, and if so, if there is any way I can undo that. The only other fix I've heard of that I haven't tried is editing the registry, but I'm hesitant to do that. I haven't tried booting from the CD drive because I have no bootable CDs and I'm worried that my computer might get stuck in that mode. I'm hoping that someone can tell me what I can do to try to fix this problem, preferably without wrecking my computer. Thank you for taking the time to read my post.
P.S. Just adding a note; I went through both the Microsoft and Lenovo Update histories and the only related updates I could find were: ThinkPad BIOS update, Easy Eject utility, Intel Matrix Storager Manager driver for Windows (32-bit), and maybe one of the two Intel Chipset Support for Vista updates. I tried rolling back the AHCI driver but it had no effect.
Solved!
Go to Solution.

Well, my problem is fixed, and here's how. I had some trouble figuring out how to contact Lenovo technical support; online options directed me to the IBM support website, which was clearly designed for businesses. Selecting the "Call technical support" option on the Lenovo support website and then choosing my country gave me a 24/7 hotline number. After waiting about five minutes on hold, a nice young fellow by the name of "Tyrese" answered (I maybe misspelling his name), but the connection was so bad that we could barely hear each other. Although he semed eager to help, when I told him my problem the first things he suggested were simple, like cleaning the drive, However, when I told him all of my efforts, described above, to fix the problem myself and read him the log from the Rescue and Recovery diagnostic program, after he checked the error codes against his computer database he promptly replied that the only fix was to send out a new drive. I was happy to have gotten such a successful resolution to a support call in less than fifteen minutes; apparently, all the work I had done trying to solve the problem myself had paid off in a way. Unfortunately, although I had tried to spell out my address for him, some of it got left off of the address label, which caused some trouble in receiving the new drive. Once I got it, I installed it using the uninstall & remove (old drive), shut down, start up, insert & install (new drive) method that I referenced earlier in this topic. I've been using the new drive since then without any trouble, so I guess that the only fix was to replace the drive. Also, I noticed that the new drive was a Hitachi, perhaps a T400/410 or T500/510 Ultrabay Slim drive, which should help me avoid the problems that other users were having with the older Matshi-ta drives. I hope this description helps anyone else having a problem with the optical drives on the T61/61p.

Hard Drive Failed - Is there a seperate warranty?

My Hard drive just failed. It is a Toshiba, and I am wondering if the apple warranty is for everything in the Hard drive, or if there are seperate manufactor warranties that apply to their components? I really don't want to have to buy a new hard drive since I am out of warranty. But I was thinking maybe the hard drive has a 2 year warranty. Anyone know?
Powerbook G4 1.5 Mac OS X (10.3.9)

This is not specific to Toshiba or Apple, but in general, system makers have different options when buying drives.
Most big companies, like Dell and HP, buy OEM drives that come without an end-user warranty. Because the drive maker doesn't have to honor the warranty directly for the end user, these drives are cheaper.
However, sometimes drives that come pre-installed in systems are non-OEM and do carry an end-user warranty. This is mostly the case when there are too many drives in the retail channel, and the big distributors "flush" the channel by selling the excess stock off to system makers.
To find out if your drive carries a separate warranty, you'll have to ask Toshiba. The model and serial numbers are available in System Profiler.
Be warned, however, that replacing the Al PB HDD is not a trivial task... if you've never done something like this, I'd recommend asking an Apple-authorized service provider to do it for you.

New iMac 750 GB Hard Drive Fail Smart Drive Test - Glitch or Problem

Greetings!
I have a new 24" imac with 750 GB hard drive which has had problems out of the box (system crashing several times a day/unable to re-start/application crashes/general sluggishness).
Five re-installs of Leopard (upgrade/clean install/install and erase)in five weeks when I finally used the latest version of Drive Genius and TechTool Pro (4.6.1). Both claimed hard drive problems. Specifically, TechTool Pro reported smart drive failure (see report below, please).
This seemed to confirm my suspicions that something was flawed with my iMac from the start.
I have returned the computer for a new hard drive.
The Apple-approved repair shop says they've installed a new 750 GB had drive sent by Apple and when they run TechTool Pro, they get the same smart drive failure report. The techie claims this is either a glitch with TechTool Pro, or with the hard drive, but that I have nothing to worry about.
What's your opinion?
Many thanks for taking the time to read this.

Greetings, all!
This has been my first posting, despite having owned 5 Macs over twelve years - which goes to show you how reliable they are, most of the time.
I am very impressed with the thoughtful responses, and I really, really appreciate you taking the time to respond.
Here's an update since my last posting. I picked up my repaired(?) iMac from the Apple-approved repair shop. The technician's report said (referring to the original hard drive Seagate ST3750640AS Q) "The drive has passed and boots into the OS without issue. Confirmed the smart status of the hard drive shows failed, but this is for an unknown attribute. This may not really indicate the drive is failing, but could be a possibility. Since all of the other tests have passed, I feel it is best to replace the drive under warranty for the customer.
About the new hard drive, the technician wrote: I have run a third-party smart utility on the (new, replaced) hard drive again and I have found that it is failing with the same error. The Apple test shows the smart status as OK.
I have researched this error and I have found that this attribute appears to be for temperature. Since both drives showed the exact same error, this attribute can be safely ignored for smart status. I was not able to replicate any issues with this machine other than the smart status failure so I do not think there is any other hardware failing in this machine.
If the customer continues to have issues, I would recommend reinstalling the OS one more time. If the issue still persists after this, then the customer should bring in the computer when issues are still happening so we can try to determine the cause of the problem better.
At first, my iMac was performing much better, but as I began to migrate data from back-up, I was not able to connect/re-establish my iphoto library, or re-establish my Apple mail accounts( both of which I have done countless times in the past without hassle).
I decided to run Apple's Disk utility which reports it cannot repair the new drive.
Just prior to my original posting, I had sent a copy of my posting to Micromat (TechTool Pro) asking for their opinion/advice.
Their response was: The SMART routines are built into the hard drive by the drive manufacturer. They are proprietary and different for each drive manufacturer. TechTool Pro just reads the status of the built-in SMART parameters and reports their status. Basically, a threshold exceeded indicates that the drive has exceeded what the manufacturer thinks are proper operating parameters for it and it may be getting close to failing. For an interpretation of the seriousness of a specific attribute failure you would need to contact the drive manufacturer. A failure is a warning to be sure to keep good backups and consider replacing the drive. If you get a SMART failure on a drive that is under warranty, the drive manufacturer will typically replace the drive.

I also took your (Looby) advice and called Seagate. (I also visited their web site, which recommends replacement of their hard drive under these circumstances!)
Within a couple of minutes, the tech person agreed that this is a serious concern and I should replace the drive.
Regarding Wiil's post, Apple's Disk utility says: smart status verified.
The SmartReporter utility reports the smart status is OK.
The SmartUtility application says:smart status failed. ID: #190 Unknown attribute.
For all other posters, this was not a New Egg purchase, which was not relevant to my post. Thank you just the same.
I've left a message for the Apple-approved store and will ask for another drive, and that, if possible, it be tested before I bring my iMac in to reduce the inconvenience.
I'm also wondering if I should switch to a 500 GB hard drive, although that would defeat the purpose of buying the larger drive for all the video I work with ( I have another 2 Terabytes storage with external drives).
Any further comments welcome - and thank you all again for taking the time!

Importing Songs from iPod after hard drive failed

My hard drive failed. Fortunately all of my songs were backed up on my iPod. Got a new computer and can't figure out how to get the songs from my iPod back to my computer. Some songs were purchased from iTunes, some from CDs. I tried the import function and all it does is bring the titles into my library but cannot find them when I try to play them on my computer. The songs are still on my iPod.
iPod 40g and Nano Windows XP

The transfer of music is designed to be one way by default - from iTunes to iPod, however there are a number of third party utilities that you can use to retrieve the files from your iPod. This is just a selection.
YamiPod Mac and Windows Versions
PodUtil Mac and Windows Versions
iPodCopy Mac and Windows Versions
PodPlayer Windows Only
PodPlus Windows Only
Have a look at the web pages and documentation for these and pick one you are happy with, they are generally quite straightforward.
There is also a manual method of accessing the iPod's hard drive posted in this thread: MacMuse - iPod to iTunes
You may already be using the iPod in manual update mode in which case you can ignore the rest of this post. In manual mode, your iPod is safe from being accidentally erased. However if you are getting a message that your iPod is linked to a different library and asking if you want to link to this one and replace all your songs etc, click *No*. Your iPod should appear in the iTunes source list. Change the update setting in Preferences>iPod to "manually manage songs and playlists" Managing Your Songs Manually
You can also use a keyboard command to prevent your iPod auto-syncing with iTunes. While connecting the iPod to the computer on a Mac hold down the Option and Command (⌥ and ⌘) keys, on Windows, hold down Shift + Ctrl. This will stop the iPod from auto-syncing with iTunes and the iPod will appear in the source list. Wait until you are sure the iPod has mounted, and that it will not auto sync and then you can let the keys go. This may take between 3 and 30 seconds depending on your computer. Then go to Preferences>iPod and check the "Manually manage songs and playlists" box.
Keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync again.

RAID 0 volume failed - Intel RST, W530 (wonder if it is hardware issue now)

Hi,
My laptop is about two years old. I got one of two intel RAID 0 volumes failed several months after I got this laptop. This problem has been on my laptop for a long time.
The functionality of my laptop started to become poor after this volume failed.In the beginning, windows explorer stopped working and restarted every time I opened the laptop. The windows repair tool said windows could not be repaired... So I reinstalled the OS and reset it to factory setting. However, the crashes persisted and gradually became more frequent. Many other error reports showed up. After searching for solutions, I finally did a clean windows install and used the BIOS Intel RST to repair the corrupted volume (I deleted old volumes created new ones).
Unfortunately, now, the same volume fail error appears again and the functionality of my laptop is impacted. Sometime I cannot save my excel or pdf file because program stop working, or cannot open a pdf file. I have to restart the OS.
The detail error message of Intel RST is: "your volume appears inaccessible. Try fixing any problems reported on the array disks. If this fails, review the Troubleshooting section under Help for more information. In all cases, back up any accessible data before taking action".
I'm now wondering if it is the hardware issue. If so, I'm thinking about buying an extended warranty because my orignal warranty has expired. However, I'm not sure if the warranty can cover this...
In this community, I find there are two types of extended warranty, one will start from the expiring date of the original one and the other will start from the date of purchase. I suppose I need to find the second one.
I'm also wondering the quality of the warranty. Will it take a long time to repair if I send it? or will it take a long time for them to ship?
Any idea, solution and experience in warranty / repairment would be appreciated.
Best Regards,
Haoyi
BTW, here is also my experience with Lenovo if you would like to have a look at:
I got my W530 two months after purchases... I found it was a common problem in Lenovo...
When my laptop was still in the original warranty, I contacted the lenovo customer service for repairment of the failed volume. Those people told me it was errors coming from my software. They said the repairment was not covered in the original warranty and I needed to buy a new type of warranty (related to software repairment). I had no confidence in the quality of lenovo's customer serivce... So I did not buy it.

Hi, Colonel,
Thank you for reply. I tried HD Tune, but it cannot show any information about my harddisk. It only shows Intel Raid 0 Volume, the firemware version is 1.0 and the capacity is 931.5GB. There is no other information, such as serial number, standard, supported, and buffer. I cannot choose supported features. HD Tune also cannot display the temperature of my drives. What should I do?

The burn to the PIONEER DVD-RW DVR-K06A drive failed. Verifying the burned

I am trying to burn an album from iPhoto '09 and I receive the following error message:
The burn to the PIONEER DVD-RW DVR-K06A drive failed. Verifying the burned data failed.
I have attempted 3 different times using the same media that worked prior to my upgrade to Snow Leopard. Prior to the upgrade I didn't have any problems.
Any help would be appreciated.

Same for me here...no luck with TDK DL DVD +R. Seems that this drive is extremely picky with DL supports (http://discussions.apple.com/thread.jspa?threadID=1181990).
