1.	Solve : 1TB external harddrive, power disconnected while in use,now won't read any files?
Answer» HI, We had brought our 1TB external Hitachi hard drive (XL1000) on which I had some movies and stuff to watch on the laptop on our vacation recently. The power cord accidentally got disconnected while the external hard drive was plugged in one of the laptops that was using a file on the external Hitachi drive. When we reconnected the power and started it up again, the laptop was not reading any files on on the external drive. It stated that the external hard drive was not formatted and needed to be formatted before it could be used. Needless to say , I DID NOT go forward with the formatting as I knew that would erase any files left in the hard drive. I have since hooked up the Hitachi hard drive to both laptops (Acer 18 months old, and a Toshiba 8 months old, both using Windows 7)) and now that we have returned home, to the Dell desktop ( 4yrs old(maybe older?), windows Vista) all with the same results - there are no files on the Hitachi external hard drive. Is there any hope in recovering the over 600GB of files on the this Hitachi external harddrive? I would crack it open and connect it via SATA to a desktop computer INTERNALLY as a slave drive to where you can address the hard drive with a bummed file system. Then run check disk on the drive to try to repair it. If the external drive was jarred when the power was disconnected a head could have made contact with platter and scratched it. If thats the case then depending on the NATURE of the physical damage check disk may not be able to fix it and you might need to use a utility like GetDataBack NTFS. I own a licensed copy of a bundle deal of their software and it works great for retrieving data that is orphaned in a destroyed file system. This software searches drives even ones that have the all so well known armature clunk failure and is able to address the drive and sweep the data off of the platters with each clunk sweep and reassemble "most" of the data. As long as the drive spins and the armature can sweep either by clunking or being addressed by the software data can be retrieved. I used this software on a laptop that took a flight of stairs as it was running. Engineer WANTED to get to a meeting and bring his running laptop with him and well....laptop slipped from his hands while running and it cartwheeled down a flight of stairs ending with a destroyed laptop and of course data that was critical and only resided on that small damaged hard drive. I got back about 80% of his data and he was fortunate that his months of work that wasnt backed up was included in that 80%. His music files etc had some stuff missing which was acceptable than 3 months of lost engineering work at a multibillion dollar corporation. Data recovery on his drive took 5 days to sweep and reassemble. His drive had the clunk of a dead hard drive. Here is the software, but its not cheap. Maybe someone knows of a free option that will work. http://www.runtime.org/data-recovery-software.htm You can download the trial of it to test before buying. I did that first and then when i saw the data just a $80 payment away, I bought a licensed copy to be able to grab that data which is otherwise read-only until fully activated to write to a healthy drive and recover. I ended up buying a bundle package for like $170 for all file systems and raid recovery TOOLS etc. Quote GetDataBack will recover your data if the hard drive's partition table, boot record, FAT/MFT or root directory are lost or damaged, data was lost due to a virus attack, the drive was formatted, fdisk has been run, a power failure has caused a system crash, files were lost due to a software failure, files were accidentally deleted.
