Windows 7: 2 TB sata external HD usb broke off

Since your USB connector broke off there might have been some electrical shock to the drive.

Testdisk can identify the drive, but there's a piece on it that cannot be analysed.

You'll need to make sure that the jumpers and BIOS are correct for that drive. You said that the jumper placement was on the drive itself, so double check it and then see what BIOS knows.



You might have to write a new MBR and then analyse afterwards.This is going to take some time and there are no guarantees. Take your time and read about Testdisk, it has much better data recovery than photorec (in the same zip file you already downloaded and extracted). But that data recovery doesn't do much good if Testdisk can't see the partition.


even more information on MBR

Hi Slartybart, (earlier I was typing startyybart - blame it on my poor eyesight )

I was focussed on another OP's problem which cropped up again and so did not get into this thread. Just now I gave it a look, but I am yet to fully comprehend what has gone on.

Test Disk seems to identify the hard disk.

Reading through I do not understand why one should deviate from Analyse to File Utilities. ( your post no.47.) ( The OP is advised to read Part two of my guide.)

What happens if one hits analyse?

How many partitions did the OP have on that external disk and in what format?

Was it formatted by anything prior to Vista?

Regarding the jumpers, let the OP tell us the exact model of his Hard disk. Then you can look into the manufacturer's website and guide him what it should be. ( I am leaving station tom morning and my return to desk here is open.No internet during this absence because of the festival + 2G not available. So my datacard will be useless in a village.)

The other point I would like to make is that in the case of an external disk, there is no need to write the boot MBR. That is applicable only in case internal boot drives, as I understand. So no write MBR. Only write partiton table if it finds.

Finally, I would say if ANALYSE does not find the partition or gives any error message, we have hit a road block.(I have to admit that apart from conducting the trial wherein I actually deleted the partitions using the same Test Disk making it unallocated and using the Test Disk to successfully find and rewrite it, I haven't had any situation requiring recovery) So we will only be using the learn and guide philosophy to the best extent possible.

That said, I would have personally preferred maintaining near-identical conditions for the hard disk by putting into another external casing. Think, we wouldn't run into jumper jumps. But then it involves cost which may look heavy if the efforts turns futile. We will carry the cross.

No, something has changed. Let me read over this thread again.

Could you PUBLISH a Speccy report (file menu publish) and post the URL it returns?

Thanks

Post 22 - 1st attempt, before jumpers




Post 30: Connected to Sata | Jumpers on 7 & 8 - as stated on sticker.
Note: OP beleives it is slave jumpering. Now that I'm writing the recap
- confirm needed. No such thing as slave Sata???????
- rejumper as master???????

Post 36: Disk Management






Post 30: Jumpers on 7 & 8 - as stated on sticker.
Post 38: Testdisk 43% - invalid boot sector




Post 30: Jumpers on 7 & 8 - as stated on sticker.
post 40: We're going to try Recover a FAT32 boot sector
Based on FAT invalid boot sector

post 43: testdisk - disk selection
(just showing the correct drive is selected for recover fat32 boot attempt)


[line][.[line]

post 49: advanced - returns No available partition
I was going to try and recover or rebuild the boot sector and not being intimate with Testdisk, believed it was in the advanced menu.

Aslo, probably confused MBR with boot sector

TestDisk checks the boot sector and the backup boot sector. If the boot sector and backup boot sector mismatch, you can:
  • restore the boot sector from the FAT32 backup boot sector if it's valid (Backup BS);
  • update the backup boot sector with the current FAT32 boot sector if it's valid (Org. BS).
Dump can used to display the sector content in both hexadecimal and ASCII.



If the boot sector has been overwritten, it's often the case for its backup also as they are very close to each other:
  • the primary boot sector is sector zero of the filesystem;
  • the backup FAT32 boot sector is usually located at sector 6.
Fortunately TestDisk can deal with this problem by creating a new boot sector from scratch.



post 53: set Testdisk options to dump


post 54: create Testdisk log at start

post 56: no change after dump and create log
might be useful to find the log and dump - saved for today's session.

post 63: return symptoms to idenitfying drive as FAT12 - as was the original attempt with Testdisk

post 64: jumanji posts inquiries and excellent advice on keeping status of disk drive the same as when the problem occurred, plus manyother insightful suggestions.
Thanks you stopping in - hope all is well on the home front. You're probably sleeping now, so I hope this recap will help if you visit tomorrow.

post 66: injmalk replies - only one partition and wasnt formated on anything prior to vista

I raised my own question in the recap and jumanji asked "What drive make and model"

injmalk, please look at this page and post a link to the correct model. Since the drive is connected as Sata, the system specs picked up the internal model.
I'll start with that information, but want to be sure.

I found the jumper settings for WD20EAR(S & X jumpers are the same). The drive default jumper is NONE.







edit: the drive was not jumpred originally. after i raised the question, injmalk jumpered 7 & 8 per the drive sticker. After verifying WD internal WD20EARS jumpers - the jumper should be removed.

so let's try this and see what Testdisk tells us.

Remove the jumper from the drive and reconnect
Reboot, check BIOS - what does BIOS think is connected?

Fire up testdisk, post screen two (drive identification/selection)

Then we'll return to jumanji's tutorial and see if results improve after removing the jumper. Or are the results no better?

I'll defer to jumanji's judgement since he is familiar with the tesdisk application. I purchased a commercial application 20 years ago, so the functionality is familair, just the operation is different. Testdisk is a great find - I paid 200 USD.

I'll be out for a while, but will check in for a status update and offer as much guidance as I can based on what you post.

Bill
