Hello to all ,

I have a Toshiba Internal HDD 500 GB 7200 rpm . (Sorry can't remember the exact model no.)

Lately it had too many bad sectors to I replaced it with a new one . Now the problem is when I am trying to use the drive as an External HDD , its not being detected . It has the windows Image but in recovery console , it does not show anything . It won't even get detected .


On this toshiba Drive i had set the "HDD Password" through my BIOS . Is that the reason for it not being detected when i am using it externally ?

Please reply soon and thanks in advance .

It could be either one the case is faulty or not providing enough power to run the drive or may be the USB part of the case is faulty. One thing is clear that the drive is ok.

And sometimes the case/caddy have different format of Allocation Unit Size. Like, if you format the drive externally (while inside the case/caddy) the format size can be of 512 bit sectors, and when you format a drive inside PC/Laptop the size can be of 4096 bit sectors. So the mismatch of format size will lead you to trouble of not detecting, or showing improper size, or unreadable file format.

So you can try another case/caddy hopefully that will work. Cheers.

I was hoping for your reply lonewolf7 , and thanks a lot for the reply. And yes I am use a case with a Sata to USB converter port .

The problem is , when I use my HDD in the case , it did got detected but its getting detected as 465GB RAW partition , but when I put the same drive inside my laptop , there are 5 volumes in it with over 300 GB of data and it gets detected and I can access is all the drives.

In fact while I am typing this , my Thosiba HDD is inside my laptop so that proves it isn't raw .

So, is the case faulty ?
