RAID 5 Data Recovery

lenovo raid serverI have a lenovo ix4-300d with 4 bays, each with a 2TB HDD in a RAID5. This evening it reported a data storage fault and auto-recovery email. Then a data protection reconstruction completed but with some potential data loss. When accessing the share it appeared as though half of the data that was present was missing from the share. I checked the interface and it showed an error with bay 1 that had a recoverable error. However, following a data integrity check and reboot the device came back online with only 1 drive showing data and prompting an overwrite of drive 3 which i didn't activate. I replaced the drive in bay 1 with a new 2TB HDD and rebooted to try and rebuild, suspecting it was drive 1 that had finally broken, again, prompted to overwrite but this time on drive 1 (the new replacement disk) i couldn't get the lenovo to overwrite the new disk 1, and was stuck in this state. Had to cold power down the box and replaced the original disk 1 back in the device. When the box was online, no shares were present at all, and the device was prompting an overwrite of the drive in bay 3 which i've ignored.

The automated errors sent on email state: "Storage failed and some data loss may have occurred. Multiple drives may have either failed or been removed from your storage system." At this point, decided to contact Data Clinic ( I'm happy to send the entire unit up to you and have a screen shot from this very morning with the size (2.32TB) and number of files (138,163) that should be across the 4 bays in the RAID5. Would appreciate an initial email on Monday rather than call back to advise of likely costs of review and data retrieval. Happy to send 2x 5TB external HDDs with the lenovo for backups.

We have an old windows 2003 server that we inherited from a merger and need to keep running for a legacy database. The server now won't boot. We suspect it to be a hardware fault but not entirely sure what at this stage. The RAID disks seem to be ok and the data intact as we can access it when we use a caddy attached to another computer. We cant get it to boot in another computer though and it just wants to run a windows repair and we don't have the administrator password. We basically need to get this disk booting into Windows again so that we can access the database. Again, this is another job for the RAID recovery experts at Data Clinic.

Recover Data from Dell Poweredge 2950

i have a server Dell poweredge 2950. it have already RAID 5 with 3 disks. i added 2 more disk.. and configured mirror RAID. But unfortunately, i intialze my RAID5 partiton. Can you please guide me how can i get my data back??? I've been told that Datlab's Raid recovery service ( is very good. Please help me in this critical issue. I am really thankful to you.

dell poweredge 2950The external hard drive doesn't power up but it makes a "clicking" sound. – It doesn't show on BIOS when starting up. – No data was written on the disk after it stopped working. – It was probably damaged due to a fall or a bang.

I have 500G hard drive in the Dell Poweredge, i did try repair my Friends laptop and i connected my hard drive to them laptop, I done something wrong and deleted all my data from hard drive plus changed size of this hard drive, now is only 30G I don't know what's happened, also I did try recovery my files with some program but doesn't work properly, I want only few G of pictures from this hard drive I don't care about rest or maybe video what I recorded, could you tell me what would be price for this service? (its a power edge 2950 series)

My WD My Passport Ultra was working fine in my Dell server tower a few days ago, and now it is chirping and doesn't seem to want to be read. I've tried running Disk Utility and WD Utilities, and both say that the hard drive is working fine; however, it's clearly not. Can you please assist with data recovery? I am running it on a 2015 MacBook Pro 13" 128 GB.

Toshiba Canvio 1TB external hard drive. Connected to and worked correctly on Sunday 21st May, video files opened and played. Monday 22nd May – plugged usb into computer. Hard drive light did not come on, no sound from the hard drive and no heat. Bought and tried a new usb cable, still no response. Datlabs data recovery have quoted me a good price on the data recovery. Hard drive contains large number of music, photo, and video files.

Critical Data Lost!

The raid array in the server reported 2 failed drives so we lost a VMware data store. The disks came backup but the vmdk file is corrupt (although vmware tools don't report it as faulty). On the advice of our support company we have replaced a single drive and are waiting for the raid array to rebuild however that may not help. We also have a backup of the faulty vmdk. There is approx 450Gb of data which is critical to us. What can we/you do next?

I managed to delete all my files and recycle bin from an ADVENT laptop so that I could take to get laptop hinge repaired, hinge cannot be repaired and turns out I did not copy my stuff to USB properly. Need to recover, photos, excel sheets, word docs, vmdk and email pst history

Its a Seagate 1tb hard drive Model SRD00F1 that has a blue light blinking when plugged in but stopped showing upon the computer altogether a couple of weeks ago. I've VMDK files and the VMWare partition seems corrupt. I've bought a new cable, which made no difference. It doesn't appear in disk utility or any other way on my Mac and I have tried to see it on another Mac with no success. It contains my entire work portfolio and all my photos from the past few years. Computers do not recognise the external hard drive.

Spilt some blue liquid from a dehumidifier on my laptop and now cant retrieve the VM Ware data off the hard-drive.
PCB board seems damaged. Tried ordering a new pcb board but cant find the exact match so ordered a similar one that doesnt work. Got suggested to solder off the rom from the broken one onto the new PCB board but not sure whether that would work.

I have an issue with my unrooted vmdk LG G2 D802 32GB Korean version. I updated the software using LG Software Updater and everything went fine (download and update process) until first reboot after update. After the phone turned on the following message was displayed on the screen: 'Unfortunately, settings has stopped' and nothing happened after. After every another reboot the situation is the same.
I am unable to start my phone in recovery mode (I also didn't do the backup thinking it will be only a simple software update without any issues). The only mode I can start my phone in is hard reset mode which I want to avoid.
I was wondering if you are able to fix my phone without any data loss or to recover the data especially photos if the fix without hard reset is impossible.

Phone Help Manchester

Phones and hard drives are always breaking a requiring data recovery and here are a few enquiries from people with very similar problems. I recommend for phone and hard drive recovery. They also have an office in Manchester. HTC one m9 water damaged. Won't turn on, took to an ismash they said they can't repair, however I don't think they had the capability to rwtrive the photos stored on there. There's no SD and I had a few months where I didn't back up, so I need to retrieve photos from the phone. Is this possible if we pull it apart and get the phone memory out? I mistakenly deleted the DCIM/Camera folder on my phone (Nexus 5) this evening and would like to recover the photos again if possible please. I can bring the phone in tomorrow morning (Wednesday). Please can you let me know if you can help. Thanks I have a relatively old external hard drive (from 2011) which I haven't used for a year. When I tried to connect it recently, I realised that the connecting point for the cable might be broken and my laptop would not recognise the external drive. Could you please kindly let me know where should I send my drive for pickup? Hard drive has failed, unable to access, require all data recoved from the drive. I can bring to Manchester I have a Sony Experia X compact and I dropped on the floor now I can not turn it back on. The screen is cracked and not usable, I need the photos recovered on this phone because I have no backup and was wondering how much it would cost and how long it would take. Spilled water on a 2015 MacBook Pro – and it won't switch on. Tried drying it out, but to no success. Hadn't backed it up recently, so I need to get work data from it.

Hard Drive Anecdotes

Broken hard disk driveBecause I work in data recovery I'm bound to see a lot of broken hard drives. In this post I write about some of the cases I've dealt with recently and provide interesting anecdotes where appropriate.

Case 1. The hard drive was attached to a NAS and the NAS stopped working. If the drive is attached to the NAS it won't start. I took the drive out of the NAS and plugged to the laptop using a USB-SATA cable but Windows can't see it. No noise, nothing on Windows. Can the data be recovered? How much would it cost?

NAS stands for Network Attached Storage and on multi disk system implies that some sort of RAID technology is in operation (read more about NAS at It'll be RAID 1 for 2 disk NAS hard drives and RAID 5 for anything above that. The drive appears dead (no noise, and nothing on Windows), therefore it's probably an electrical fault and the data should be recoverable. The cost will be about £450.

Case 2. I have a 1TB external Seagate drive which I was using as a Mac Time Machine backup (see Vital time machine backup notes at and has a large archive of family photos on it. While trying to restore to my Mac it started to malfunction, running slow and crashing the Mac. It is still live and I can mount it and see the root directories but can't copy anything off it. Can you assist and what are your rates?

I believe your hard drive has media degradation. The data on it should be recoverable, but you're going to have to send it to a hard drive recovery company. Take a look at a good data recovery web blog like for good recommendations on hard drive data recovery companies.

Case 3. My Seagate external hard drive isn't being recognised in any computer. I have contacted seagate and tried all their suggestions but still no luck. I have to send it back to them to get a new one as its still in warranty but would like all the data taken off if possible, they do do data recovery but its not covered in warranty and its more than i would like to pay! If you could let me know a rough price that would be great, thank you.

It really does depend on what's wrong with you hard drive. You don't provide any symptoms so it's difficult to give an accurate diagnosis of the problem. In cases like this the best I can do is provide you with a guide price for the recovery which will be somewhere between £350 and £800.

So I hope these anecdotes will provide some insight in to the world of hard disk recovery. Please let me know if you have any questions.

Surveillance CCTV

Much of the United Kingdom is under surveillance. From the CCTV systems that seem to be present on every street to GCHQ intercepting emails and internet traffic. I wonder how people actually feel about this? Is this data surveillance ok with everybody? The common phrase that is brought forward with this argument is "if you've got nothing the hide then there is nothing to fear", but this is a statement that simplifies much of the arguments about our data and its privacy (or lack of).

This article discusses how data is recorded on to CCTV and how it can be used. Modern day CCTV recording uses hard drives to store the recorded data. When video recording systems were first introduced in the 80's the images were recorded to tape - typically video tape - as the advent of video recorders spawned the CCTV industry. It quickly became obvious though that video tapes were not of sufficient capacity to record large amounts of CCTV information. With the storage capacity of hard drives growing exponentially from 2000 - 2010 (in 2000 a typical hard drive capacity was 1GB, in 2010 it was 1TB, and now in 2016, it's typically 4TB).

A 4TB hard drive supplies a huge amount of storage capacity for CCTV systems, a 4TB hard drive will be able store months of data from several CCTV cameras without using up all the storage space on the hard drive. Large hotels and factories that require CCTV surveillance have CCTV systems that use multiple hard drives to record images - often in HD.

What's The Best Way To Configure a CCTV System?
Most CCTV equipment comes preconfigured. The only thing that its necessary to do is to fit the cameras and plug them into the central DVR recorder that stores the CCTV images. Best practice is to configure the DVR as a RAID 5. The reason for using RAID 5 is that it provides protection from data loss - one of the hard drives in the DVR can fail with no data loss. To run a RAID 5 requires a minimum of 3 hard drives and so is only really found in larger CCTV systems. For data recovery purposes, I recommend that you always use RAID with your CCTV systems.
