The Specified I/O operation on Device/Harddisk1/DR7 was not completd on USB

By ailoss ·

I am having problem with my Seagate USB portable HDD 120gb. It was working properly for 2 years. but this week i started to get this error: "The Specified I/O operation on Device/Harddisk1/DR7 was not completed before time-out period expired." after 20 seconds when i plug it to my PC. and windows does not see my portable hdd.
as i contacted with the Seagate support they told me that hdd is dead and they offered me to their back-up company. actually hdd doesnt have guarantee.
the important pointy is i have 110 gb data inside and it is shame that i havent got backup! these files are very important and i have to recover them anyway.

so i would like to ask here to the proffessionals: what would you offer me to do now?

one of my friend told be to open the box and take the hdd out and install it to another PC. he thinks that it is because of the cables in the box.

i will be very glad if someone help me..

Well it depends on how important the Data is here

If it is Important and Must Be recovered I would advise you not to touch it at all. Just send the entire thing to a place like On Track and let them loose with it. The more you mess around now the more expensive and less likely a Professional will be able to recover the data.

But if the Data Isn't that Important and would only be Nice to get back there are several things you can try which will be cheaper than sending the drive away and paying a Professional to recover the Data.

Start off by ripping the external Enclosure apart and removing the drive. But do this genteelly as you don't want to hurt the drive any more than it currently is. Fit the drive to a Suitable USB Enclosure and then plug into a computer and see what Happens. If it appears Backup Immediately that sort of goes without saying but some people seem to forget that HDD's are a Mechanical Device that will Fail. It is quite possible that the Electronics in the Interface between the HDD and the USB Lead have failed due to excessive heat.

If it doesn't appear open the Drive Management and see if there is anything present listed there. What is happening now is a guide on how to proceed latter. If the HDD is present and wants you to Format it you have not been using the Safely Remove Option in Windows and have corrupted the Partition Information this requires the use of a Data Recovery Application to recover the Data.

If there is nothing there the HDD has failed at some level which may or may not be possible to recover from. If the drive can be heard spinning up it may just be the Electronics on the Circuit Board bolted to the Bottom of the HDD and you can buy another HDD of the Same Make & Model remove the screws from the Circuit Board and swap Circuit Boards. This may make the Drive usable again but if it does Expect the drive to fail totally so Backup Immediately.

When All else fails Stick the Drive in a Freezer Bag and stuff it in a Freezer for about 18 hours to get cold. Then plug it into a computer system but keep the drive eternal to the computer and try to read it now. If it works get your Data off Immediately and then scrap the drive. This is a Last Resort and should only be an option as such. I have covered a HDD in Dry Ice to get the Data off it and it worked but you have to be very careful.

Now if you need to use a Data Recovery Application to recover the drive there are a lot of different possibilities around and it's impossible to have used them all so here is a short list of the more commonly used ones.

While the last 2 are from the same company they are very different products. Win Hex should only be considered for use by someone who knows Hex Inside Out while Davory is a great cheap General Purpose Application.

Personally I prefer the On Track Option but it's anything but cheap. However because I use this type of software a lot it's paid for itself many times over by now, for a cheaper option Spin Rite from Gibson Research or Stella have both very good reputations by other TR members.
