Next: mysterious discrepancy in the reported free space on two identicalusb drives
From: sobriquet on 18 Feb 2010 06:40 Hi. I've lost some data on a 2 tb WD mybook usb drive. When I did a full scan, it found something like 3 mb in bad sectors. However, when I reformatted the drive, somehow all bad sectors were recovered. Apparently, there is some redundancy in diskspace, so it can allocate some of that extra space to substitute for the bad sectors on disk when it's just a small section of bad sectors. The disk is also able to pass the short drive test (in winDLG under xp), that it used to fail, before I reformatted the drive. Now I wonder if the fact that previously bad sectors have occurred and I've lost data, is that increasing the likelyhood that this might happen again? Is the drive less reliable in any way once a small number of bad sectors have been identified (even though the bad sectors are no longer visible after the drive has been formatted again and other drivespace is substituted for the bad sectors)? Below is the original log from chdsk when the bad sectors were found: Checking file system on G: The type of the file system is NTFS. Volume label is My Book. A disk check has been scheduled.

You really need a proper SMART report on the drive. That isnt necessarily that easy to get for free with an external drive.

Well, with winDLG, it does say the SMART status is OK for the device, and I can get more detailed SMART info. Here is a screenshot of the SMART info: http://img11.imageshack.us/img11/74/wdmybook.jpg

And the reallocated sector entry and the temperature entry make no sense either. The Everest SMART report is much more readable, but doesnt work with external drives in the free version. smartclt from a linux bootable cd might, and HDSentinal might, but it isnt free.

The version I've tried from HDSentinel wasn't up to date, but perhaps the version (5.30) of Everest on demonoid will provide more detailed SMART info on the drive. I'm busy with the drive now, but I'll soon follow up on this with a screenshot of the Everest SMART info of the drive. |
