For those wondering about SSD Recovery, anything with a multilayered board inside is subject to water and contaminant damage if it's compromised. Yes, there aren't any moving parts, but electronics and water-borne contaminants do not get along. Aside from the corrosion problems, contaminants also generate static charges, something not covered in this article. I worked in Class 100 and 10k clean rooms for years when I was a Federal Gov't QA Inspector assigned to key NASA programs. I've even done some HD recovery operation in my time before they had services like DS, where an entire system was submerged in saltwater for a couple of days, then flushed out with a firehose.
Multilayer boards, when submerged in water, will soften unless it is completely covered in a thick layer of conformal coating. Water gets into everything, even circuit IC's. Even if the board doesn't come apart, if water gets into an SSD, eventually rust and contamination will compromise the drive. The problem with any contaminants is that depending on the type of contaminant, it can alter the drive's read/write ability since they're all magnetic.
DriveSavers has several good recovery programs they recommend, but realistically they are a last resort company, when the drive has physically failed, or in this case it is severely damaged from elements. Of course in the end, it depends on how much the data is worth to you.
For those who save their data off site, that's great, but I don't trust anyone with my data. If you do, then you're more trusting than most. I guess I've been in the business too many years to trust anyone with critical data. I don't even use public sites or public email services like Yahoo or Gmail. Using an offsite storage service isn't even a consideration - it's too tempting for people today to sell data, especially if it's e-commerce related. Some e-commerce laws specifically tell operators that personal data must be kept under their control at all times, meaning they can't store it offsite unless it's at a company division that belongs to them. For one of my clients, they maintain all personal and financial data onsite, and offline, where all ecommerce is completed online and data not kept onsite is purged from the online server after the transaction.
You're right - DS isn't cheap. But there isn't much they can't recover, and if you really need it, they're worth it. One thing not mentioned in this article is that they also have a special Media Division, which specializes in the recovery of Audio, Video and static picture files from drives. They have helped many movie and tv studios, actors, musicians and many others from disaster. One of their more famous cases is the Simpsons, where they recovered several episodes from a damaged drive.
If you're wondering - yes, I'm a DS Reseller Agent. But I wouldn't be if I didn't think they were worth the service they provide. Working long hours in a 10k clean room isn't fun.
