RAID hard drive failure in HPZ420
I have a HPZ420 PC which contains a 4 disk raid 10(0+1) configured system which is unable to boot from the operating system. The PC is used to control and receive data from a scientific instrument. A week ago when the PC was working fine I noticed that one of the disks had failed and an HP engineer was called out and replaced the faulty disk but would not reconfigure the RAID system. The PC was still working fine at this point, so I decided to do a back up to external disk overnight, unfortunately the PC failed to complete this before going into its current state of losing the ability to load the operating system. I would like to recover the data.
Lost data on Playstation 4
I basically connected my hard drive with a PlayStation 4; and unplugged it without ejecting it properly – now, when I connect it with my computer it shows up but it doesn’t show my files. I had a chat with my college technician and he believes that it’s not corrupted but we can’t quite figure out the problem. I am just wondering if you are able to get all my work back as it is super important? How long it can take as it is college work and I need to hand it in? And how much do you roughly charge? Thank you so much. I look forward to hearing back from you soon.
Data recovery charges can vary between several hundred and several thousand pounds. If the problem is on a single hard drive (like a PS4) then the cost is usually much lower than if the problem is spread across many hard drives like on a RAID system. My advice is to do your own research and find a decent data recovery company who can help you.
Device: HP Mediasmart Server EX475
Problem: Worked fine from purchase in 2007 until it failed to boot up just over 4 years ago. Spent an age and a fortune on phone calls to HP support to talk me through the recovery process, which didn’t work. At which point they ran out of ideas and I ran out of money and will to live. I am now wondering if it’s possible to at least rescue some data, if not get the thing working again. I have all the original manuals, installation set-up and recovery discs.
I sent some RAID 5 hards drive to ‘Rapid Data Recovery’, who replaced some parts, but in the end were unable to recover any data. They sent this message:
‘…analysis of the medias platter surface revealed inconsistencies of the magnetic properties which could potentially be linked to the contact made between the head and platter surface resulting from the initial ‘head crash’. This may have been caused by one of several factors ranging from environmental impacts (e.g. a drop or bang) up to temperature expansion of certain components. Due to this preventative damage caused we were unable to initialise the heads long enough for a forensic scan to take place before further damage was caused to the replacement read/write heads.’
I read that you sometimes receive hard drives that have already been to other data recovery companies, because you have more advanced techniques. Is there a chance Data Clinic would be able to recover my data?

Recovering data and files from servers like the HP EX475 needs to be completed in a careful and considered way. From previous experience the company Data Clinic are probably the best RAID data recovery experts in the UK. Just Google ‘data clinic’ and you’ll find them.
