It will remain there on the platters, which is why professionals can still recover information from a water damaged hard drive.ĭepending on the circumstances, however, the data may become more difficult or perhaps impossible to retrieve. While water can damage a hard drive’s electronics, the data itself is stored magnetically. When a hard drive gets wet, the water could potentially cause a short circuit, especially if it dries on the platters.īut water alone will not destroy a hard drive or delete its data. The first question you’ll want to ask after a spill is “Will water damage my hard drive?” The answer depends on the circumstances of the incident and the actions you take.Ī hard drive stores data magnetically in its platters. For example, the files for your operating system and software programs are also kept on your hard drive, making it a critical part of your computer’s functionality. Not only does it keep the pictures, videos, music, files, and other information you save, but also the information required for your computer to run. Your hard drive is the device used to store and access data on your laptop or desktop. Take the time to learn about this issue and the steps to recover a water damaged hard drive, so you stand a better chance of successfully recovering your hard drive any time it gets wet. You could lose important information, waste valuable time, and even have to replace your hard drive. Hard drive water damage is a common problem for both work and home computers. Give the drive to a data recovery specialist.Do not let your brother-in-law touch it.Gently rinse with clean, cool water and seal it in a Ziploc bag.Leave the protective covering on the drive.Do not dry the hard drive with a hair dryer or in the sun.Do not attempt to plug in the hard drive.Tend to the water damaged hard drive immediately.Here are 7 steps to recover data from a water damaged hard drive: Many ATA commands have SCSI equivalents and can be translated or at least tunnelled, but a lot of cheap USB-SATA 3 adapters don't actually bother to translate all of them – only the most common ones (read, write, identify disk, read ATA SMART data).Īs an example, a lot of USB-SATA adapters won't support issuing TRIM commands to SSDs, even though there is a direct SCSI equivalent and a translation could be performed.Ģ With lower-density disks, overwritten data could potentially be retrieved using expensive physical inspection (hence the "3-pass DoD wipe" and similar), but nowadays that's pretty unlikely to work.ģ The official name is either "SATA" or "Serial ATA".Spilled water on your hard drive? Don’t despair just yet! If handled properly, information can often be recovered from a wet hard drive. (Moreover, "regular" Mass Storage devices speak a very limited subset, while the newer UASP standard is more flexible.) On the other hand, beware of adapters that translate too much – there exist some which actually remap sectors to a different size (making a 512b disk appear like a 4K one) when connected through such an adapter, the data is technically still there, but at completely different offsets, so the OS wouldn't even recognize completely intact filesystems.ġ This is partly because USB storage devices talk SCSI, not ATA, so the adapter has to translate. (This may confuse tools like "ddrescue" which try to copy partially damaged disks.) It is often useful to have several adapters that are built with different controller chips. if some sectors are physically almost unreadable, the disk might still keep retrying but the adapter might already decide to "give up". That being said, some USB adapters don't deal well with damaged disks, e.g. In particular, there is no "undo write" or "recover sector" command in disks – once a sector is overwritten, it is overwritten. While it is true that there are many commands that won't work through many USB adapters 1, none of those commands are generally used for data recovery. a photo was "deleted", but the actual JPEG data is still there, it's only not attached to a folder anymore). Data recovery software typically just reads data sectors the same way the OS would – it only uses different approaches at finding data that might still be there (e.g. Is the data recovery process sending some low level commands to the hard-drive which might be lost if transmitted via USB? This might depend on the tool, but yes, it should work the same as with a directly connected disk. It is possible to use it for deleted files recovery from a notebook SATA hard-drive?
