My WD not showing the hard drive

WD External Drives External Drives for PC
1

Hello everyone

My apologies for repeating what seems to be a problem shared by others but i thought i would explain my own situation to hopefully get a solution.

Ive been using a WD my Book 500GB Essential USB2.0 External HD for a few years now and all of a sudden the E drive is not showing.

Ive tried different cables but to no avail.

Ive tried the HD on two different computers and both computers seem to recognize that ive plugged something into the USB but no additional drives are showing up.

The BIOS seems to recognize the HD and Windows XP installs the drivers but for some reason i just cannot see the drive.

THe Ex HD is making no noise and seems to work fine apart from the fact i cannot see it :slight_smile:

Any advice would be hugely appreciated as i have some really important documents on this HD and like the biggest numpty ever ive not backed up some of it elsewhere …

Thanks in advance

Jos

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.

How does Microsoft’s UVCView utility see the external drive?

Thanks for the link.

Sorry for the delay, but the external HD was with a friend who was having a look at it for us, sadly he could not find a solution.

This is what the UVCView utility shows.

** edit ** seems ImageShack link does not seem to work.

I have inserted the USB into the front of my computer but not sure which port that is.

In port 7 it says USB Mass Storage Device with the following on the right

UVCView is correctly identifying the USB-SATA bridge IC. It also appears to be seeing the drive behind the bridge. The serial number “57442D5743414D5233393938363738” is encoded in ASCII hexadecimal. You can use Debug in a Windows DOS box to decode it.

C:>debug
-e 100 57 44 2D 57 43 41 4D 52 33 39 39 38 36 37 38

-q

Can you see the drive with a utility such as HD Sentinel or HDDScan?

http://www.hdsentinel.com
http://hddscan.com

If so, what does the SMART report say?

6

Downloaded the hard disk sentinel trial v.3.60 but not sure what im looking for.

All i can see is the C: drive which seems to be fine, but no other drive is shown.

7

With the HDD scan there seems to be 2 drives as follows .

Tried to copy and paste but it would allow it due to body error , so saved as text.

Not sure what you meant by Debug in a windows DOS , that sounds complicated ! :slight_smile:

9

ISTM that your C: drive is a WD3200YS-01PGB0, which is a 320GB SATA model. HD Sentinel and HDDScan both see it correctly.

However, your My Book 500GB Essential is being detected as a WD3200JB-00KFA0, which is an older 320GB IDE drive, not 500GB. Are you sure you have the correct capacity?

Furthermore, since it is an older drive, it could be that the USB-PATA bridge chip inside the enclosure is unable to communicate SMART information, which would account for HDDScan’s nonsensical SMART report.

As for debug.exe, this is a powerful DOS utility that is included with Windows. I have used it to show how you can decipher ASCII data without having to consult ASCII tables. You can see the decoded “WD-WCAMR” model number in the output.

10

Thanks for the reply, really appreciate it.

Im not sure of the capacity to be honest , maybe it was a 320GB …ive had it a while and maybe i just presumed it was a 500GB.

What would you suggest i do now, debug exe ?

Do you reckon there is a chance i could get back at least some of the data?

11

We need to determine whether the drive has a logical problem or physical problem. A logical problem is one where there is file system corruption. This often happens when you disconnect the drive while it is being accessed, or before the write cache has been flushed. A physical problem can be the result of bad sectors or a more serious fault.

Inside the enclosure you have a USB-SATA bridge board. Your PC talks USB, the drive talks SATA, and the bridge IC handles the translation. UVCView has confirmed that the bridge is working correctly.

The drive also appears to be working, at least in part. Assuming that it is in fact a 320GB My Book, then the drive is identifying itself with its correct model number, serial number, and capacity. You can confirm this by verifying the model number or part number on the enclosure.

You should see the drive in Device Manager and in Disk Management. The fact that it is not assigned a drive letter would suggest that your OS doesn’t recognise the file system, or that there is a problem with the FS. Depending on the OS, you could also try manually assigning a drive letter to it.

The SMART report could have told us if there were bad sectors, but unfortunately these data are unavailable to us.

You could try using HDDScan to scan the surface of the drive. This should produce a bad block map. Otherwise, if HDDScan balks at the first sector, then I would suspect a more serious problem.

12

All this computer talk confuses me :slight_smile:

Ive just plugged in the external HD and in Hard Disk Sentinal i selected disk / surface test.

It seems to show two discs

[0] 298GB  C: WDC3200YS

[1] 298GB  WDC WD3200JB ( no drive letter shown )

Do you want me to start test on the second one ? ( test type - Read test )

13

Yes, test the WD3200JB drive.

14

This option is only available after registration and activation.

Does this mean i have to buy the product to do a surface test ?

15

OK, my apologies , got confused a bit there.

I was trying to use the HD Sentinal for some reason, did not realise i was suppose to use the HDD Scan for surface test .

Executing as i speak …

On a side note …  the WDC WD3200JB is now showing up on the HD Sentinel but health and Temp is shown as ?

Would you like any information from the information tab ?

16

If the surface test is running, then it appears that the drive is accessible. I expect that HDDScan will find some bad blocks. If so, then your best approach would be to clone the drive, sector by sector, using a utility that knows how to work around bad patches in the media. Ddrescue and dd_rescue are two freeware cloning tools. Then use data recovery software on your clone.

17

Thanks again fzabkar for your help on this …

I ran the HDDScan exe file , chose the right drive and selected Surface Test and added Test Read .

I left it run for possibly 3 hours and all it did was say the status is Executing and the HD just kept flashing that yellow circle.

I stopped it then pressuming it did not work, how long does it take to normally execute ?

18

If you assume that the average read transfer rate is 100 MB/s, then a full scan should have taken less than an hour.

(320 x 10^9) / (100 x 10^6) / 60 = 53 minutes

ISTM that the drive has some serious physical problem. :frowning:

Diagnosis is being complicated by the USB enclosure. Ideally you should remove the drive from the enclosure and connect it directly to your motherboard. However, this will only be possible if your motherboard has an IDE (PATA) port.

Before you open the enclosure, could we see the partition table and boot sectors with Microsoft’s Sector Inspector?
http://www.users.on.net/~fzabkar/SecInspect.zip

Extract the above archive to the one folder and execute the SIrun.bat file. The procedure will generate a report file named SIout.txt.

Error 1117 was encountered reading from \.\PHYSICALDRIVE1.

The request could not be performed because of an I/O device error.

Not sure if i did this right, extracted secinspect.exe and SIrun.bat into a new folder and then ran SIrun.bat.

ISTM that the external HD has real problems. Sector Inspector can’t read the very first sector. Is it possible that the drive is password protected??? Do HD Sentinel or HDDScan mention anything about the drive’s security status?
