Also, if you have a device that is faulty think about what personal data is stored on it before you dispose it. Remember that just because a device will not turn on does not necessarily mean that the data is not accessible by someone. Personal data can be stored on any device with a permanent memory, including desktop and laptop computers, external hard drives, games consoles, mobile phones, tablets, faxes, printers, and removable memory such as that found in digital cameras.
When deciding what to do, consider the type of media the data is stored on and whether or not this is easily accessible. Once destroyed, data on the media will not be recoverable except using specialist, expensive equipment. You will have to replace the destroyed media with a new storage facility if you want to use the device again.
If you are not able to remove the media from the device you will have to destroy the device itself. Fragment particles raise health, safety and environmental concerns. Consider specialist help for devices with hazardous elements eg mobile phones and batteries. This will return the device to the state in which you bought it. This method relies on the device manufacturer to have implemented a secure wiping stage into the factory reset process. There are many organisations which will securely delete data from a range of devices and types of media.
These organisations will destroy or overwrite your data on your behalf. A full format can be used in conjunction with overwriting to provide further assurance that data cannot be recovered. Desktop and laptop computers will have a hard drive inside where your data is stored. Above you'll see some common types of hard drives found in PCs and laptops. Securely deleting data from the cloud or other remote storage service cannot be achieved by you running overwriting software.
You should contact your cloud provider to see what service they offer to securely delete the data. It basically allows you to securely delete files as well as securely wipe RAM, swap and free disk space. All there programs are open source so if in doubt you can inspect it to ensure that it does what it really says on the tin. Just visting the site could give you a trojan dropper or something. Interesting thread. On a PC it might be possible to wipe the ram on shutdown by allocating a memory block big enough to force page file swapping.
This might have the added benefit of wiping the disk cahe as well. It meets U. DoD guidelines, so it should do the trick. Won't do anything about RAM, though. That's way over my head, sorry - but probably, someone else here will know. I probably should have said "mostly" rather than "usually". Some devices, however, log activity. Most of this is harmless, e.
It depends on what kind of data is of concern. Ingo New Member. Glenn said:. You must log in or register to reply here. Great service and I would definitely recommend them. Would recommend to anyone needing help salvaging their hard drives. Data Recovery Specialist help me retrieve the data quick.
It's not a cheap service but it works and the data recovered was far more valuable than the repair cost. I contacted several companies and opted for DRS. Collection of my device was simple, the turn around time was quicker than I expected and they kept me informed right through the process. Really pleasant and professional company.
My interaction with Daniel Rees was very good, he was honest with what he could do to recover my very important Data. I also found their customer service department especially Roger a pleasure to deal with.
Rapid, amazing service. These guys are the pros! My hard drive was collected quickly by a pre arranged courier service and returned quickly in the same manner. I was kept informed by telephone at all parts of the recovery and all my data was returned. I can fully recommend this company to anyone.
