Hi Thomas,

1. Ask are you refering to Hard drive or Network drive?
2. Do you get any error message?
3. From which location are you trying to open this drive?

This issue occurs because the same device instance ID is assigned to the drive when the drive is moved to a new slot. Therefore, Windows uses an incorrect interrupt line for the drive.

Method 1:

a. Restart Computer
b. Insert a drive
c. Open Computer Management
d. Go to Disk Management
e. Right Click on the Disk Currently Inserted and Change Drive Letter & Paths
f. Give the drive the first permanent letter (i.e. E, F, G, etc)
g. Now remove that drive and do the same w/ # 2.

If your drives are recognized properly by the computer, you should be able to hot swap them now and have them keep the same drive letter.

Method 2: Run the fixit

Hardware devices are not working or are not detected in Windows

Device Manager does not display a drive after you hot-swap the drive between slots on a PCI-E switch in Windows 7 or in Windows Server 2008 R2

Sandeep,

What is network drive,? I just put the hard drive into hot swap enclosure. When I went to disk management, I only see C drive unless  I scan it, but I could not see the files in this drive even though the drive was shown and the cursor was keeping running. Please advise.

Thank you !

Thomas

Sandeep,

I forgot to tell you, I open this drive in window explore. Thanks . Thomas

Thank you for the reply.

Have you checked if the 1 TB hard disk shows up in the disk management. You can refer the below article that will give you information on Opening Disk Management:

http://windows.microsoft.com/en-US/windows7/Create-and-format-a-hard-disk-partition

If you are able to see the 1 TB hard disk from the disk Management, I suggest that you change the drive letters for the drive and check if it shows up in the Windows Explorer.

Refer this article that will show you ‘How to change drive letters’:

http://windows.microsoft.com/en-US/windows7/Change-add-or-remove-a-drive-letter

Also check if the drive is formatted with NTFS.

Unfortunately just having a removable drive bay does not make it "hot swap". It requires the proper interface in the bay and the SATA chipset has to support that function.

Unlike USB devices standard SATA cannot have storage devices removed and added on an ad hoc basis. The commonest real application for hot swap is actually in a RAID array where the operating system does not have direct access to the storage space.

Basically the drive has to be in the bay when Windows starts.

Hi, Sandeep V,

Thank you for your all information, I tried but all failure. I give up. It is because blue screen is shown all the time.

Thank you so much !

Have a good long week-end !

Hi Thomas,

In order to rectify the root cause of the issue, I would need to look at the dump file to check the last driver/program that caused BSOD in the computer. Please attach the dump file through skydrive and reply back with the link.
