This sounds very much like the back plane ( the board the disks slot into ) is faulty on that one slot. It is a hardware problem with the server not the disks.

I just experienced my third ST3500418AS failure in 3 months. My disks are in RAID10 (1+0) configuration, so I've just been returning the drives, and the RAID rebuilds, but what's going on? I get...


Since you have so often problems, I suggest to take a look at the controller also (firmware etc). If it's possible use another one (in case of independent controller). A good idea is to check for hard disk firmware update from official seagate site.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

FAIL-SAFE FILE SERVER AND COMPUTER SYSTEMS

If your data is very important, you should consider doing regular data backups because hard disk will fail at some at some stage in the future. This is especially true when you get an error message"hard drive is about to fail".

Depending upon how critical your computer or files server to you or your business, you should consider building a fail-safe computer or file server system using RAID technology. RAID means "A Redundant Array of Inexpensive Disks" and there are several levels of RAID.

For details of different RAID levels - click on this link -
http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci214332,00.html

The most common of the fault redundant RAID systems are -

RAID 0 + RAID 1 provides fastest data transfer Mirrored hard drives.

RAID 5 is one of the most popular system, it data striping across hard drives with error correction. It has excellent performance with fail-safe system and allows for hot swappable hard drives.

There should be redundant powers supply inside the computer or file server in the event of a power supply failing.
Another consideration is to install a UPS (uninterruptible power supply) to prevent a computer or server shut down from power outages, as this will corrupt your data.

These systems do not mean you should not back up your data on a regular basis.

How we know RAID 5 subsystem going to failed one


The manufacturer of the RAID interface-card has software that can be installed to monitor the RAID, and to identify any "failed" disks, and to "rebuild" the RAID array after a new disk-drive has been added to the array.

My computer says Disk Read error. What should I do?


first go to bios settings and see if the sata bus is set on raid or achi and disable them ..and let it on ide compatible or on native .. and save the changes with f10 and exit .. If this was teh issue .. and you changed the settings and the raid driver was missing it will work again .. or .. you will just have to reinstall the operation system again .. and also change the settings I mentioned first .. or if you use it on raid .. make j\sure you have an operation system with raid drivers (windows 7 or vista ) or .. you load the drivers when you start the installing as 3rd party ..
Also check the hard disk to be well powered and plugged in well

A DRIVE RAID 0 VOLUME IS FAILING GENERATION 2


> RAID

Rapid Array of Independent Disks

RAID logically combines several identical disk-drives for better performance or for better reliability.

For better performance, one RAID configuration "stripes" the data, i.e., when you write a block of data, the block is split into "stripes", and each stripe is written to a different disk-drive.
Since each stripe is smaller than the whole block, it is faster to transfer the data in "parallel".

For better reliability, another RAID configuration writes each block of data _identically_ to multiple disk-drives. Thus, if one disk-drive fails, your data still exists on the other disk-drives.
You can then replace the "bad" disk in the array, and use software to "rebuild" this "mirroring" of your data, by copying all the data from one of the "good" disks onto the "new" disk.

So, in your case, one of the disks in your array is failing. Identify it. Replace it. Rebuild your array.

The hard drive fell over and now it wont stop making alarm noises and it wont work


I'm afraid the disk got damaged internally. If it was set to RAID 0 mode (speed), at least half, possibly all data is probably lost.
If it was set to RAID 1 (safe) mode, maybe the data can be recovered. It's not very likely, I'm afraid, because in this case the drive would make noises but would also work. I fear you had two 512 Gb disks configured as RAID 0. For RAID 1, it is sufficient to open the enclosure - it has three small screws on the side - and unscrew the four internal screws holding the drive caddy. Extract the caddy, unscrew both hard disks, and try connecting them, one at a time, to an external SATA to USB adaptor (Kraun makes a very handy USB to SATA-EIDE3.5-EIDE2.5 adaptor with external AC, but many exist).

In RAID 1, one of the disks might be detected and work (of course, both could have been damaged, but that would be real bad luck).

In RAID 0, sometimes it is possible to partially recover one of the disks (with half the data). It takes lots of luck, not all RAID 0 enclosures support this.

If you can't recover the disks easily (the RAID 1 trick is almost immediate), I'm afraid your only option is a data recovery service :-(

Harddrive array sequence causing system in booting


If the only drive you changed was the drive that failed and all the others are in the correct sequence, then that's a good thing.

The next question is, did you have this system setup in a RAID Array and if so, what RAID configuration were you using (RAID 0,1,5, etc.)? Some RAID configurations allow you to replace a failed drive and not lose data, but I will need to know more about how you set the system up in order to help you more.

I have hp proliant with raid 1+0 .I have 2 hard and usr in option


Sometimes shortened to RAID 10, RAID 1+0 is a particular combination of two different RAID levels: mirroring (RAID 1) and striping (RAID 0). The appeal of RAID 1+0 is simple: mirroring gives you the highest level of availability RAID offers, with the fastest rebuild times when a disk fails; while striping - using the proper chunk size - is the basis for high-performance I/O.

Help please to restore the failed raid


Well if your data is gone at this point, you mines well just proceed with rebuilding a new RAID 5 set with your replacement drive. Even if one drive fails in a RAID 5 set, your logical drive should still be accessible. Goodluck.
