Need help with HD
My 3T external HD went haywire and I lost more than 600 albums that I had downloaded... If there is anyway to recover them, Id appreciate some advice. Thanks a million.

"Haywire" isn't exactly a precise technical description of what happened
When a disk fails, you're typically looking at one of two reasons: 1. Logical issue, like a corrupt filesystem. Recuva might do the trick in this case, however, there has to be a reason why that happened in the first place. This needs to be investigated. 2. Physical issue, damage to the actual drive. With external drives, there's also the (usually) USB to SATA controller which could be part of the problem. Sometimes, 1. and 2. are combined, like a faulty controller successfully writing corrupt data to the disk, causing logical damage. Assuming the drive controller is still working, check the SMART values of the drive. They might give an indication as to what happened. CrystalDiskInfo is one of the most user friendly tools for Windows for that. If the physical state of the drive is questionable, don't try to recover files now. Create an image of the drive and work with it instead. Instead of doing than on your current OS installation, you could also boot SystemRescue: Code:
http://system-rescue.org/ If possible, it might also be helpful to remove the drive from its enclosure and connect it directly to a host. It removes a potential layer of error. This isn't possible with all external drives. All of this requires a certain level of technical expertise. If you're not familiar with the matter, you should seek help from a professional. There is a chance that you make it worse and prevent an otherwise possible rescue attempt. I know it's too late now, but the single most lesson I've been teaching people over the years is that a backup is essential. Never be without a backup, unless you're ok with loosing the files in question. Drives fail all the time and even in 2023, people are still learning this the hard way. |

Most of the time it is the case connections or curcuits of the external HD that become corrupted and the HD itself is undamaged. However sometimes a case curcuit can also damage the HD. If a curcuit has shorted out then you made not be able to properly read the HD without removing it from the external case in order to take an image of the HD's contents. If you need to remove the HD from the external HD case then you will need to connect it internally to a computer. Do not format the drive or you will lose all the files. Once connected you need to copy the files to another HD that has enough space on it. Mostly likely you will have to copy the files as an image of the HD and then uncompress the image. If you need to uncompress the image then you will need double the space plus the amount allocated for the buffer. Since your dealing with a very large drive it may be best to connect the HD from the external HD box inside your computer and connect a new external HD and then clone the drive. Depending on your OS you can select which cloning software will work best for you. All this is assuming that the actual HD still powers up and the damage is restricted to the external HD curcuits.
