Drive isn't recognised in Explorer

Sat, 2012-11-24 18:24 by Karol · Forum/category:

I inserted another hard drive into my computer, but connected it through a switch to the power supply.
The drive is connected to the motherborad, just like the main hard drive, which holds the operating system.
This is to prevent viruses, etc', since i intended to switch it on only for backup.
At the beginning it worked even when the computer was on, i mean when i turned the switch on, i saw the backup drive in the browser and could transfer files to it, but now i don't see it anymore, even if i shut down the computer and restart after switching on.
I see in the bios that it recognises the disk, but i still don't see it.
To test, when i turned the switch off, the disk doesn't appear in the bios.

Connect/disconnect while running

What type of data connection does the drive use? SATA?

The suspicion is that the content of the drive got damaged when it was switched off while it was active.

SATA has Plug-n-Play capability, so you can power up the drive while the computer is already running, and it should be recognized.

But that does not necessarily mean you can power down the drive while the computer is running. You would have to go through the securely remove hardware dialog first. If you forget that, you could damage for example the partition table on the drive or some other essential data area. Perhaps that is what has happened.

I suspect that even the securely remove hardware procedure is not always sufficient to allow you to cut the power before removing the data connection, but I am not sure about that.

What to do?

So, you say i must use DOS and the FDISK or FORMAT commands?
I have to see the drive somewhere

Windows Disk Management

You don't have to fall back to DOS. Windows can do it too. A help page for Windows XP is here, for example.

Primary partition, formatted

Tue, 2012-11-27 08:21 by admin

Explorer shows only formatted partitions that Windows can read. Try to create a primary partition and format it with NTFS (or FAT32). If a partition is already there, check whether it is a primary partition and whether it is formatted. If in doubt, remove it and create a new one.

Note that all data that may have been in the partition before will be lost.
