reading /dev/sdb[Input/output error]

[Xcross87]

Hey guys, I have a big trouble here.

 

I have an external hard drive WD7500, and it worked fine but just 2 days ago, something happened and now I can't access to anything inside it.

 

First, i try lsscsi

[0:0:0:0]	disk	ATA	  Hitachi HTS54161 SB4O  /dev/sda
[1:0:0:0]	cd/dvd  MATSHITA DVD-RAM UJ-850S  1.10  /dev/sr0
[2:0:0:0]	disk	WD	   7500AA External  200i  /dev/sdb

 

it founds my external harddrive WD.

 

Then I try to look for it in partition table with diskdrake, then the result is

Then. I try to connect it to Windows Vista, in Disk Management section => it shows: Disk 1 (Unknown): Unreadable, 698GB Unallocated.

There's no other options for me to do anything like: Format, Create New Volume, Initialize Disk (MBR/GPT) ..

 

Then, I try to connect my external drive to another computer using Vista, in Disk Management => it shows: Disk 1 (Unknown): Uninitialized, 698GB Unallocated. It gives me the options:

1) Initialize the disk: I try this one, and choose MBR but it went to errors "This request could not be performed because of I/O device error"

2) Create A Simple Volume: I try this one, and the same error appeared.

 

=> Thought of driver, I tried to reinstall driver, update .... none of them worked.

 

Can't think of anything, I try to connect to XP, well, XP doesn't even recognize anything.

 

And then, I tried to connect my external harddrive to MacBook, in Disk Utility, it recognized my drive, however, can't format, can't do anything over it because they all give the same error: "Resource is busy"

 

....

 

Again, I tried to look for solution, thought of hardware problem: power supply, adapter, cable, connection device .... but it isn't.

 

I don't really know what to do now ....

 

Please give me some help, a little hope that I know I can survive my drive...

Either the included drive went BLR, or its power supply is inadequate.

Is the disk bus powered, or it does have it own power supply?

tks scarecrow for reply.

 

It's just an external harddrive with an adapter for power and USB cable.

 

I also suspect this adapter, somehow, if I only connect the power to the drive with connecting with turn-off computer, it's getting hot (just warm lightly, not hot).

It didn't happen like this before.

 

Could you think of any idea for this?

You could try to power it with another 12V power adapter, provided that its plug would fit into the drive socket.
