What is the proceedure for replacing a hard drive (after failure) for RAID 5 with IX4-300D?

I have the IX4-300D with 4 hard drives (identical Seagate drives) using RAID 5.
Someday a hard drive will fail and I and I have to replace it. I read through the users manual briefly and I didn't see any documentation on how to perform a hard drive replacement and not lose any data.
So here are my questions:
1) I know per the instructions that Lenovo prefers using identical hard drives. Let's say in 2 years, 1 hard drive fails. Most likely, the same model Seagate hard drive will not be available. So will using a replacement hard drive by the same manufacturer with similar specifications work?
2) Will the front panel (or the software) tell me which hard drive has failed?
3) What is the proceedure for replacing a hard drive after a failure occurs? I read that the IX4-300D is not hot-swappable. So do I just power the IX4-300D down, replace the hard drive, and turn it back on?
Solved!

Hi exceptionalht,
It is best to replace the hard drive with one that is the same manufacturer, rotational speed, and capacity, so it does not have to be exactly the same model.
The front panel should show which drive has failed. If not you can check the web interface to find out.
That is the basic procedure for replacing a hard drive. You can see a more detailed instructions here: Installing hard drives in an ix4-300d

Looking for replacement internal hard drives for a MacPro

Looking to replace internal hard drives in a MacPro. Was thinking about 3TB. Any recommendations?

Look in System Report for the link speed available. (Mine says 3 Gigabit.) Get drives with at least that speed; going beyond that won't get you any more performance.

What is the opt folder in my hard drive?

What is the opt folder used for in my hard drive? All I know it has some files for GIMP and gutenprint.
Should I leave that folder alone?

Many open-source software projects (like gimp) use the /opt folder. If it's not there, they will create it when you install them.
In a standard unix-like operating system (and darwin, the unix-like foundation of mac os x is no different), the core binaries are installed in /usr/bin or /usr/sbin, and core libraries are installed in /usr/lib, and there are specific directories where the system looks for specific types of information... However there are lots of dependencies amongst this core functionality: more than one binary application can use the same library.
If the user decided to install some additional software, (and usually the admin password is needed to do it, right), the user has authorized the installer to do what it needs to do to get the software installed, even if this means updating one of the libraries to the most recent version. In this case, what happens to all the other software already installed that used the old library? Well... what happens, is none of the old programs work anymore.
The workaround has been to create a separate directory for additional software installs, so that the core functionality in /usr won't be threatened. Many software projects created a directory inside /usr called /usr/local in which they install their components. Other projects use the /opt directory. Others use /opt/local.
This is why, in unix-like operating systems, you find repititions of the same folders in other folders (i.e., there is a /usr/bin and a /usr/local/bin and an /opt/bin). The "bin" is a common name for folders that contain binaries (commands and applications that are executable and built for the specific operating system that they are running under), and "lib" is a common name for folders that contain libraries. You can find "bin" and "lib" folders throughout your system.
One downside to this is that additional programs installed into the "opt" directory could interfere with the ones that are already there, and for this reason, some programs will create their own directory all to themselves and install everything they need there, even if most of it is a copy of libraries that are already present somewhere else on the system--space is less and less of an issue in the age of terrabytes.
If you learn make your own binaries by compiling them from source code (way easier than it sounds, as you usually only have to type "./configure" and wait an hour for it to finish, "make", wait another hour, and then "make install"--really that's all there is to it) then you can control which directories the software uses (whether to use /usr, /opt, or to create a new directory entirely) plus you can run lots of cool free software.
So that's what the opt folder on your hard drive is for.

How do you replace a hard drive on a xserve raid

I am running an old xserve (10.3.9) I need to replace one hard drive in my raid set. I have a new hard drive exactly the same as the one I am replacing. Do I have to do anything in raid admin (version 1.2) or once I insert the new hard drive will it just start working and the other drives will start talking and writing data to it? Thanks for any help!

Hi
Slightly confused about what it is you actually have?
Do you mean an XServe like this one here:
http://www.google.co.uk/imgres?q=XServe&num=10&hl=en&tbo=d&biw=1433&bih=856&tbm= isch&tbnid=VXlw7-KP6nEsaM:&imgrefurl=http://inertz.org/2008/01/xserve-an-impress ive-multitude-of-potential-used-server/&docid=HT9gRAJQrNrS8M&imgurl=http://inert z.org/wp-content/uploads/2008/01/xserveg5.jpg&w=600&h=361&ei=9YPQUI6dLeX-4QTwloC 4Dw&zoom=1&iact=rc&dur=639&sig=102214044775849835144&page=1&tbnh=144&tbnw=242&st art=0&ndsp=35&ved=1t:429,r:3,s:0,i:124&tx=152&ty=81
You can't/don't use RAID Admin on an XServe.
Or do you mean an XServe RAID like this one here:
http://www.google.co.uk/imgres?q=XServe&num=10&hl=en&tbo=d&biw=1433&bih=856&tbm= isch&tbnid=-wl73CtlayTBlM:&imgrefurl=http://en.wikipedia.org/wiki/File:Xserve_RA ID.jpg&docid=9pxrypAvxoLK-M&imgurl=http://upload.wikimedia.org/wikipedia/commons /0/06/Xserve_RAID.jpg&w=1296&h=416&ei=9YPQUI6dLeX-4QTwloC4Dw&zoom=1&iact=hc&vpx= 709&vpy=345&dur=119&hovh=127&hovw=397&tx=170&ty=57&sig=102214044775849835144&pag e=1&tbnh=81&tbnw=252&start=0&ndsp=35&ved=1t:429,r:11,s:0,i:148
If it's the above simply remove the drive module and assuming you have a replacement drive module and drive, insert the new drive module. If you only have the drive, release the plastic moulding at the foot of the removed drive module, release the screws, remove the drive and reverse the process to install the new drive. Insert the module and the rebuild should happen immediately and you can use it normally while all this is happening. Depending on how much data you have stored on the unit, performance loss should be minimal. I would monitor the progress using RAID Admin.
As ever try and make sure you have a full and effective back-up handy just in case.
If it's an XServe you're going to have to provide more information as what you do will depend a little on how the RAID set was created.

What is the best pre-installed external hard drive for my macbook pro?

I need advise on what kind of pre-enstalled external hard drive which supports both usb and firewire to get for my new macbook pro? I would like to stay in the $100. range but am willing to go higher .

Pre-installed with what?
Your best bet is to always format a new hard drive, so there are no surprises.
If you buy an external HD specifying ready for Mac ( or some such) it will cost you more for nothing.

What are the symptons of macbook pro hard drive not running fast enough

what are the symptons of the hard drive not running fast enough

Physically the drive will be as fast as any other of its class, and if not then it's experiencing a mechanical issue that should prompt a warning or two in the system, especially if you use a drive management tool like Disk Utility that checks the drive's built-in "S.M.A.R.T." diagnostics.
As for "logical speed," if there are bad blocks on the drive where sectors cannot be read or written to because of a breakdown of the storage medium, then this can result in a program or the entire system crashing or hanging (generally the latter is the case), where it usually pauses for a number of seconds at a time. This is usually accompanied by messages that state "I/O Error" or other similar warning in the OS X Console (in the Applications > Utilities folder).
Beyond this, drive formatting errors such as might happen after a crash or power outage can result in similar hang-like behavior, though this is usually not as distinct of a hanging behavior as is seen with bad blocks.
Finally, if the drive is simply full of files or highly fragmented (not as much of a problem in OS X, but it can happen), then this can reduce access time for reading and writing files, and prevent the system from optimizing the use of RAM, which can result in overall slowdowns. Heavy drive use can also cause similar bottlenecks, but this is ususally only an intermittent issue during a time when you are performing a heavy file transfer or copying process, or other task that occupies access to the drive's index and formatting (e.g., if you check it for errors with Disk Utility, then you may see the system pause or slow down during the check).

What is the cost of replacing iphone 5(broken screen, out of warranty) with a higher model maybe 5s? In India.

Hi,
Yesterday i dropped my phone and the screen got shattered. The phone is working fine. but the screen is cracked.
After searching through the internet, i found out the following options:
Getting Out-of-warranty Replacement.
Getting the screen repaired by Apple Store.
I am located in India and had bought the phone from India only.
So my questions are?
What is the cost of getting an out-of warranty replacement for iPhone 5?
Can i get a replacement for a higher model of iPhone( maybe 5s or upcoming iPhone 6). If yes, how much extra i'll have to pay?
Is it possible to repair the broken screen in India? if yes, what will be the tentative cost?
Thanks.

iPhone 5 screen replacement at an Apple store is ~$120.
The price of getting the screen replaced in the US on the 5 is $150, and it is only available on the US as of now.
iPhone 5 screen replacement at an non-official Apple retailer is $75-90
Should the OP decide to go that route, he will be forfeiting future support from Apple, both in and out of warranty
A new/refurb 16GB iPhone 5 from Apple is ~$400
A used 16GB iPhone 5 on Craigslist or Swappa is ~$275-350
Apple no longer sells the iPhone 5. They keep a number of units on hand for out of warranty service, which is $269 in the US.
Buying from Craiglist (or on-line) is usually risky as the phones turn out to be not what they are advertised as.

Erasing Time Machine hard drive after formatting for both PPC and Intel

Ok, I made a mistake. First I formatted a Western Digital 500 gig hard drive for both my wife's PPC G4 laptop and my own Intel MBP laptop, so we could both use Leopard's Time Machine for backing up to the same drive. That wasn't my mistake though, it's been working fine. I formatted my partition using the GUID option and hers using the Apple Partition Map option (I think that's what they are called, I'm going from memory).
Here's my mistake: I needed some extra space to store some files and read that I could Re-Partition the drive without erasing anything using Disk Utility. Sounded great. I first tried to partition my wife's partition, since she had more extra space, but then I realized that was a bad idea since I had formatted her partition with using the Apple Partition Map, so I stopped and then tried to Re-Partition my side. It worked for about an hour: my Time Machine backup drive appeared, my new partition appeared, but then... her partition disappeared! Usually whenever one of us plugs in the hard drive using the firewire cable, both partitions appear, Time Machine Goes to work, and that's that. When we need to disconnect from the drive we have to eject both drives, but no big deal. Now her drive isn't appearing.
So... I tried to repair it, no good. Tried to erase both her partition and mine (to just start over): no good. I can't do anything to either of these partitions now, from either computer. Tried everything I could think of in Disk Utility, from both computers. Won't erase, won't re-partition. Not a hardware issue: it all started when I did this stupid Re-Partition. Help!!!!
I want to erase the drive and start over. Can anyone advise??

Jasonmo,
First, let's talk about the various partition schemes. A partition scheme applies to the entire drive. Specifically, these are different maps written to the drive, within which volumes are created. As such, this is an either/or thing; your drive is partitioned using either the GUID Scheme, or the Apple Scheme, not both.
"Live" partitioning or re-sizing of existing volumes is supported only under the GUID Partition Scheme. If the drive wasn't using this scheme, you would not be able to re-size as you were attempting to do. Even re-sizing under the GUID scheme requires that the drive's maps and directory structures be in very good shape, if it is to work without hitch.
Are you absolutely certain that there isn't some physical problem with the drive, or with its interface (cables and such)? If it is operating normally, you should be able to re-partition it without problems. In DIsk Utility, select the drive (not a named volume that will appear indented underneath), then click the "Partition" tab. If you wish to be able to re-size volumes later, you must choose the GUID scheme from the "Options..." dialogue sheet. Set appropriate sizes for the volumes, then click "Apply." Doing so will destroy all current volumes and data on the drive.

Replaced my hard drive and can't sync with PC

Hello, I had a fault on my PC and have had to have the hard drive replaced. I have loaded iTunes up from the web site and connected my iPod. I did backup my library prior to having the disc replaced and have managed to bring it back in. However, it says that the purchased music won't sync as the PC isn't authorised.
can anyone help?

You need to play at least a part of songs purchased from the iTMS to authorize them. They won't copy to your iPod until you do this.
How to transfer Purchased Music from iTunes to your iPod
iTMS Song and Computer Authorization
If you've played & authorized them in iTunes and they still skip, try this. De-authorize the computer in iTunes/Advanced menu, then re-authorize it. You re-authorize it by playing one of the songs purchased from the iTunes Music Store within iTunes. It should ask you for your Apple ID and password, and then the computer will be authorized again. Sync your iPod with iTunes, and those songs should play on the iPod once again.
Another common cause of this is not having the latest version of iTunes.
If you are using the latest version of iTunes (6.0.4), then you need to make sure your iPod software is up to date also. Get the iPod Updater software, install it, run it and update your iPod.
When you have done this, authorize your music in iTunes by playing a few seconds of it within iTunes, re-sync your iPod, and it should transfer by whatever synching method you choose.

Had to change hard drives after failure... How to restore iTunes library?

Hello-
I had to install a new internal hard drive yesterday in my PowerBook, and am wanting to get my iTunes library onto it. I am still able to access files and folders from my old hard drive, fortunately. In order to restore my library, can I simply just copy my iTunes library from my old drive to my new one, or will there be permissions issues, etc? Thanks in advance-

I was able to do this successfully and see my library w/o trouble. However, iTunes no longer sees my computer as being 'authorized' to play my previously purchased music... Is there a simple way to correct this? I also started another topic related to this here:

What is the exact type of internal hard drive I buy?

Hi all, I want to upgrade my 160GB drive, can someone advise me on what exactly it is I have to buy. And also th ebest name brands. I have macbook 13". I know western digital are pretty good, any other ideas?
Tracy

Any 2.5" notebook SATA drive up to 320 GBs will work. The Samsung 500 GB drive will also work as it's the only one that is 9.5 mm high and will fit in a MacBook.
Notebook drives are available from many different manufacturers: Seagate, Toshiba, Hitachi, Fujitsu, Western Digital to name a few. You can find benchmarks, comparisons, and reviews at Bare Feats and Storage Review.

How to Replace existing Hard Drive with new Hard Drive, while keeping old files

Hi All,
I have recently replaced my hard drive on my Macbook Pro, with a new hard drive. The old Hard Drive was 160 GB, while the new one is 320 GB.
What I did before replacing it was clone my hard drive using "SuperDuper". I cloned it to the new hard drive and then simply removed my old hard drive and installed the new one with the clone on it. Then I booted it up and began running it. In fact I am using it right now.
My questions are:
Is this a good practice?
Will this work, without problems, indefinitely?
Is this the prescribed way to upgrade ones laptop hard drive?
The reason I did it this way was because I upgraded to Mountain Lion via the apple store download and I do not have the CD for the OS. So I figured if I could make a bootable copy, that might work. So far everything seems fine, but I really just want to know if this will last for a long time. I plan on also making a partition with Windows on it also, so I was wondering if anyone can comment on that too.
If anyone can comment or give any advice on this topic I would really appreciate it.
Thank you very much!
Cheers.

Every thing is fine except Super Duper does not clone the recovery partition. If you start your MBP holding the OPTION key, you should see the internal HDD and the ML recovery partition.
You can reinstall ML or reclone using Disk Utility>restore.
Ciao,.
