Recovering archive data from tape

If you have any type of data stored on tape and no longer have the hardware to recover the files then allow me to redirect you to this earlier data tape recovery blog post. Here are two examples where there is a requirement to retrieve old archived computer data from tape storage. This is sometimes referred to as eDiscovery.

  • We have a DAT DDS3 TAPE with a backup made by BACKUP utility under DEC ALPHA DS10 running OPENVMS 7.3, and we want to get the backup file from the TAPE to hard drive on PC but we do not have access of TAPE reader.
    We just want to get the backup file, i.e one file of size 3,4 GB
    We would like if your are able to do that and for what price.
  • I have 1 or 2 quarter inch tape cartridges containing a CPIO (or perhaps tar) archive from a 1990’s Unix workstation while at college. How much would it cost to transfer their contents to DVD or USB stick, assuming they are still readable? I’m located near Chiswick.

Retrieve data from backup tape – Leeds data recovery

Putting away information (‘data’) for a significant amount of time is a prerequisite for some organisations. Numerous individuals don’t understand that the data tape is as yet a noteworthy player in the capacity data storage, because of its cost, amount of information that can be put away and the timeframe that data can be put away for. eDiscovery is a large part of tape data recovery.

In contrast with HDDs, SSDs or even the Cloud, the data tape is far better when it comes than long haul chronicling. Be that as it may, in case you’re new to tape or need some more data on the utilisation of tape for capacity then the underneath data should help. On the off chance that your inquiry or circumstance still hasn’t been replied, at that point get in contact with a data recovery tape specialist.

With the end goal for you to work out whether the tape is a decent decision for your capacity needs, or on the off chance that you are uncertain about how Data Clinic might almost certainly help you retrieving data from tape, for ediscovery or other purposes, underneath are some famous situations and questions that we have looked throughout the years.

retrieving data from tape

I have various tapes containing chronicled information. I have to get to it, yet I can’t discover the equipment/reinforcement programming to reestablish them.

In the event that you end up in this position, at that point your first port of call is attempt and get a duplicate of the reinforcement programming by reaching a product seller or merchant on the web. In spite of the fact that by and large, you may wind up in the position where the product you need is never again sold. If so, at that point your most solid option is contact an information recuperation expert. Organisations like Data Clinic have explicit apparatuses and equipment that enable them to recoup information from tapes without the requirement for the old reinforcement programming.

I need a specific record that is put away on one of the tapes I have. How might I discover which tape holds this record?

Reliant on the product and tape library framework you are utilising, you might probably – as the tape library head – utilise a code order to find the particular document. To have the option to do this however, you should know the careful name of the record you are searching for. Regardless of whether you do know the precise name, there still might be an opportunity that you recover the wrong duplicate of the document, similarly as with any propelled reinforcement there are a few duplicates of a similar single record. To keep away from this, a straightforward arrangement is make a record and index of all the tape media. This would spare time and be financially savvy.

It would appear that the information on my tapes has been eradicated or erased coincidentally. Is there any way I can get it back?

This isn’t something that you will almost certainly do without anyone else’s input. Having the option to recuperate any kind of information, from a media should just be finished by an expert information recuperation master. Numerous recuperations that are done in the hands of somebody that doesn’t have a clue what they’re doing, can result in irreversible harm and much more information misfortune. Recouping from tape is a standout amongst the most developed sorts of information recuperation; exceptional devices, equipment and a lot of learning of the manner in which information is organised and spared are expected to play out a tape recuperation.

I have various tapes in various arrangements. How might I institutionalise them?

Relocating your tapes so they are all on one stage is a smart thought. Not on the grounds that the stages may not be sufficient, yet most of the stages once presented are a distant memory. On the off chance that the equipment for those tapes never again exists, issues can happen when information on those tapes should be gotten to. Having the option to get to the information on your tapes is fundamental, particularly on the off chance that they hold any touchy data. There are as yet various tape and reinforcement stockpiling framework designs accessible to the market. Picking the one that works for your organisation’s needs is the most ideal approach as there is no genuine ‘best sort.’ If you are contemplating moving the majority of your tape information to one combined stage, specialists like Data Clinic can help you preceding the procedure, and prompt you on any dangers related with the relocation.

I’ve endeavoured to get to the information on my organisation’s tapes yet they are stating they are clear!

On the off chance that you are encountering this issue, at that point your most logical option is contact an information recuperation expert like Data Clinic. Particular equipment can be utilised to sidestep the issue and recoup the information, yet this should just be finished by an expert.

The tape peruser I have is never again working. How might I get to the information I have chronicled?

Sadly, without the tape peruser, you have no chance to get of having the option to get to that information you have documented. On the off chance that you end up in this circumstance, clean your tape drive; they were built for hard core work and toughness, so with some karma, it might begin to work once more. On the off chance that this neglects to work, either investigate purchasing another or utilised drive of a similar brand and model or convey the gadget to a master like Data Clinic.

How we do a ‘Chip-Off’ Forensic Data Recovery on a Mobile Phone

Forensic data recovery and mobile phone investigation is the process of salvaging data from failed storage devices such as mobile phones or hard drives. We offer our services across a wide range of devices. Here we will look at our mobile phone side of the company, more specifically what is known as a chip-off operation. Chip off is a useful technique especially in forensic data recovery, also known as digital discovery, or eDiscovery: these are methods of data investigation used by police forces and insurance underwriters. Data Clinic Ltd are experts in recovering data from damaged phones and hard drives.

With any mobile phone or tablet, we initially attempt to inspect the phone, we determine if the failure is with the peripheral components such as batteries, charging ports and screens. If this is the case, then we wouldn’t need to go any further. For a lot of ediscovery data investigations cases however, this option serves as a process of elimination and if this first attempt of recovering the data is unsuccessful then we look at the more advanced options available to us. This is typically in the form of advanced micro soldering, JTAG or a Chip-Off operation.

So, what is a ‘Chip-Off’?

A Chip-off is the process of de-soldering the Flash Memory chip from the failed phone / tablet in the hope that we will successfully read its raw data independent of the device.

How do we do a Chip-Off recovery?

In order to complete a forensic data recovery on a mobile phone it’s first necessary to determine that a Chip-Off on a phone / tablet is needed then the next step is preparation. The phone must be fully dismantled, including the removal of any protective metal heat shields. When this is done we identify the eMMC (or NAND) memory chip place the PCB into a special holder underneath our stereo microscope as shown here.

What is now needed to remove any underfill from around the memory chip and add specialist flux to the chip. The Flux we typically use is Amtech Tacky Flux – the idea with this is to dispense it all around the chip then apply heat to it.

The main heat application we use is a Quick 861DA heat gun (image below). This is a station that offers a wide range of options when it comes to applying heat. We make sure to select a correct temperature, airflow and nozzle to do the job properly.

Once the chip has been lifted from the board after carefully applying the correct amount of heat we get the de-soldered chip, we then proceed to cleaning and re-balling the chip. This is a meticulous process whereby we need to ensure that each of the 100+ solder contacts have clean solder. It is a manual process that you need skill in precision soldering and a keen eye under the microscope to do.

Once each pin has been successfully and soldered in a uniform manner, it is time to clean it up with specialist chemical solutions. This ensures that the contacts are as clean as they can be and thus the read of the chip should also be good!

There are a lot of readers and programmers available worldwide that you can use to read the raw data of an eMMC NAND memory chip. The honest answer is they all have different capabilities for different chips. Its not a case of one is the best. Here are some samples of these available ‘boxes’. When it comes to data discovery and mobile phone investigation the phone data is fully dumped to a binary image file, we then analyse and decode the raw data. Once reconstructed we can send our customer a summary to let them know the recovery statistics as shown below.

This data can then easily be transferred to another storage device (typically a memory stick) and returned to the customer.

To Summarise

A chip-off is one of the procedures that really is a last resort. Chip-off cases are applicable when:

  • The logic board is too severely damaged to repair

  • ediscovery / digital discovery / forensic phone data recovery is required.
  • The lock on a phone if it is not known and there is no method of bypassing it via software

  • Corrosion cannot be decontaminated

  • For deleted data

The art of performing a chip-off is something that we pride ourselves on being able to achieve, we have recovered the data from many phones where this was the only option and are still carrying out these procedures today.

Digital Evidence Investigation – Data Recovery and E-Discovery

As more of our lives are stored digitally, so more of this digital information is often seen as evidence. Maybe a phone contains images from a crime scene, or perhaps a hard drive contains an important email that warrants a forensic investigation of the data. One term for this is forensic data recovery.

Most data recovery companies are able to examine data forensically. Digital evidence examination basically looks at the data on a digital storage device in an attempt to discover if there is any pertinent information detailing illegal activity.

Enquiries for e-discovery (or ‘data discovery’) as it is widely known vary. Here are a few examples from clients wanting a forensic examination of their hard drives and mobile phones.

Linux ext4 formatted 2TB WD HDD that is fairly new. Will not initialise or mount. Has 1TB of films I need back as the online backup has, incredibly, failed at the same time. I have a spare drive to move the data to. I’m interested in having this data examined forensically – I think the phrase is e-discovery or examination of digital evidence.

My Seagate External Hard drive has stopped working, and the light will not light up. However it does ask for me to initialize the disk, and makes a clicking, beeping noise.

Over christmas I took a lot of video footage on my phone to make into a short movie – i put my SD card into my laptop and transferred the videos onto my desktop or iCloud, i also made folders for them on my SD card, now when i came to open the folder it has turned into an exec file which now it won’t open my videos and i fear i may have lost them! i tried to download a free software to try recover the data but it only recovered the audio and even then it was broken, i believe that the footage is still there i just need a way to bring it back, now my Mac is not recognising my SD and i don’t want to keep trying unless i cause further damage. It is only now that I realise that some of the footage may contain digital evidence of wrong doing and it may be necessary to reproduce this in a legal case. What facilities exist to examine the hard drive, SD card and phone forensically? Can you examine each of them and produce a forensic report as the what activity has taken place on each?
