Knowing the basics about the types of data loss and how to recovery your files from a failing or failed hard drives can help you be better prepared on how to deal with the situation. Types of Hard Drive ddrescue: write error: input/output error Failures - Physical and Logical Physical failures typically mean that the drive has experienced some dd error reading dev sdb input output error sort of physical damage and the mechanical parts of the drive are malfunctioning or no long working correctly. Logical failures mean the file

system has experienced some sort of corruption. What Causes Hard Drive Failures? Physical failures are generally a result of the drive being mishandled (dropped, bumped). If the drive is shorted out by an electric surge, if power is http://forums.macrumors.com/threads/data-rescue-ii-urgent-question.380396/ cut while the drive is writing data, or if dust/debris manages to make it inside the drive housing can all cause physical failures. Physical failures can eventually occur overtime an extended period of time as the drive is used or, while not as common, can result from a manufacturing defect which is the reason many drive manufacturer provide a warranty. Logical failures are caused by deletion of critical system files or the system not being https://www.prosofteng.com/blog/failed-hard-drive/ able to find those critical files. It can also be caused by improper shutdown of the machine, including power loss, as well as malware attacks and software conflicts.

Software data recovery such as Data Rescue 4, and physical data recovery that requires the drive be sent into a Data Recovery lab such as The Data Rescue Center where the drive will be repaired to a state in which the data can be extracted from the drive. Typically you will want to try a software recovery first since it is possible to do it yourself at home and it is a significantly cheaper route. If a software recovery is unsuccessful, the next step would be to look into a physical data recovery services. Data Rescue uses an advanced scan engine and reconstruction algorithms to piece the data back together using the file patterns found during the

I recently connected it via https://discussions.apple.com/thread/1782184?tstart=0 USB - just like any other day. However, this time it failed to mount right away and the activity light was steady. Additionally, it didn't show up in Pathfinder, Finder or Disk Utility, so I felt it safe to just unplug it after waiting for about a minute. I went through these same steps a few times. Eventually, I decided to unplug the drive from the outlet after having success with this once before. After this, output error I received the error message "disk you inserted is not readable by this computer". This was very disconcerting and I unthinkingly clicked "Initialize" without first looking into what exactly it did. This was a big mistake, apparently, since I was reading around in another forum and a user urged against this. However, he also said this option doesn't format the drive - it simply makes it appear as blank. He suggested using Disk Warrior. However, my data rescue ii drive doesn't show up in DW. It does show up in Disk Utility, but as 2 TB WD Media (it's only 500GB) as 'Unformatted'. This has me spooked. I think I may have accidentally formatted the drive due to lack of instructions on the "Initialize" option.Does anyone have any reassuring words or am I up a creek without my data..?Thanks,Michael MacBook, Mac OS X (10.5.5), C2D 2.0GHz, 2GB RAM, 250GB HDD Posted on Nov 7, 2008 9:59 PM I have this question too Close Q: disk you inserted is not readable by this computer All replies Helpful answers Page 1 Next by Zlig, Zlig Nov 7, 2008 10:45 PM in response to bathat Level 4 (1,340 points) Nov 7, 2008 10:45 PM in response to bathat Hi you should be able to recover your files using [Data Rescue|http://www.prosofteng.com/products/data_rescue.php].

However, I've already tried Data Rescue II a bit and it didn't find any files. Should it be possible to restore files if all I did was select "Initialize"? I'm curious if maybe cutting the power caused the problem. I've done it before and everything was fine. I'm
