The company I work for has a Qnap server running a RAID setup which I believe to be RAID 5. It has 12 disks which are a 2TB. Over the last week 2 of the hard drives in the array failed and now the server will not start. I have swapped out the hard drives with hot spares but the system still does not boot. We are in the London area and there is a similar system with the same problems in the North West – Manchester to be specific. This is an identical 12 disk RAID 5 system that is running in degraded mode. We need the data from both ideally as quickly as you are able to recover it. Do you provide an emergency service?
The server started running slowly about a month ago and we only had limited access to our files. The machine contains server VMs on a network share and we can’t access two of them. The Virtual Machines are important and they contain data that run some business critical operations including an MySQL database. I’ve looked at the RAID 5 BIOS settings and can confirm that two of the drives are offline and the RAID is running in degraded mode. Ideally we would like you to collect the whole system and recover the data off the QNAP RAID onto something similar that we can attach to our company network that everyone can have access to.
We have 2 raid 5 arrays that need looking at. Array 1 – 4 x 500 gb disk array, one disk failed possibly due to overheat. We cannot get the array to rebuild. I have a new disk for replacement.
Array number 2 – 4 x 500 gb disk, Working OK but 2 drives accidentally removed while machine on. 2 drives still up, 2 drives OK but not online. Drives in both arrays Seagate Momentus 7200.4
What are my options in recovering the files from these raid 5 arrays?, based on us delivering the HDDs and whatever other kit you need, and 2-3 day turnaround? We are a located in Manchester
One of the raid 5 disks is a hard drive was from an external enclosure, has since been removed as I thought it might be the enclosure causing the problem. The hard drive used to show for a couple of seconds on Windows but then became unresponsive and ejected itself. The hard drive does turn on and spins and is detected by windows but will not show up in the disk manager. We consulted raid data recovery company Data Clinic in Manchester (Bury) and discovered that plugging the hard drive directly into my motherboard froze the PC at boot completely. Connecting it to the raid 5 array for data recovery purposes has a similar effect on the raid and we can not access any of the files stored on it.
The raid 5 arrays use the same hard drives – HGST HTS541010A7E630. When we take these hard drives out of the raid array and connect them to a computer some are recognised, others are not.
Hard Disk Sentinel gives health of 0.
Can anything be done to recover data?
Here are some data-recovery queries I’ve had recently:
When I turn the power my computer I’ve been getting this error msg verifying dmi pool data so I tried to use a windows recovery disk I place it in my DVD driver & try to boot the CD then when the screen says press any key to boot I press a key then I hear this ticking sound coming from my hard drive do I need replace my hard drive?
Seagate Hard Drives Not Found
Hi, I have a Seagate portable drive that I accidentally unplugged from my Mac a few days ago. When I pushed the USB back in, my laptop no longer recognised the drive, and the drive itself made a beeping noise every second and the light on it kept flashing. Just wanted to find out how much it would be cost to get it fixed or get the files off of there. Through Seagate it’s several hundred pounds and I definitely can’t afford that as a student ha! Thanks in advance.
I have a seagte portable hard five, it got bumped or knocked over in the house. I would like to get information like photos recovered from it and was looking for a price.
I’m currently working away at the moment so a reply by email would be good.
I live in the glasgow are so could drop drive Into lab.
My advice would be to try Computer Science Labs at http://computersciencelabs.com
Emergency RAID Data Recovery
I have a home NAS unit ( Netgear Duo).
2 x 3TB raid drives for media, photo etc.
The unit fell about 30cm.
The drive now click, then after about 30 minutes go quiet, I can see about 2% of the data. ( just one folder tree) and open documents.
The rest is not visible.
I have not tried anything to avoid data loss.
My advice would be to give these people a ring: http://emergency-raid-datarecovery.com/
External hard drives certainly aren’t new but they are extremely popular. Many households have more than one and companies can have hundreds. It’s the convenience and portability of external USB hard disk drives that makes them so popular.
External hard drives can be single disk systems or multiple disk NAS devices, some running RAID. Most connect to either a computer using a USB connection or a router. This last option is very popular as it allows everyone who can connect to the router to share the data on the external hard drive.
External hard drives also get knocked over or dropped, when this happens, and it happens quite a lot, they break and the data on them is lost. External hard disk recovery is possible but it takes a skilled company to do it. A dropped hard disk will often make a buzzing or a ticking sound (often described as the ‘click of death’ – Wikipedia link here). In both cases symptoms like these indicate that the hard drive has mechanical damage. I’d recommend anyone who has dropped a hard disk and broken to contact an external hard drive recovery company like Data Clinic Ltd (their external hard drive page is here) if they need to data off the disk.
Once a hard disk has been dropped it can’t really be repaired to such an extent that it’ll work without problems again, frequently data from dropped hard drives is transferred across to another external USB hard disk drive that hasn’t been dropped and works perfectly !
