On my T410s with Windows 7 Professional 64-bit, the "Safely remove hardware and eject media" function is very slow.
It need take about 30~40 seconds from me clicking on the safely remove hardware icon to the menu popping up.
But if I open the "Devices and Printer" in advance, it's only need one second to show the menu.
Is there anyone know how to solve this problem?

I am also seeing this issue with my T410. With just a single USB flash drive in my computer, I click on the Safely Remove... icon in the system tray and it takes anywhere from 10 to 20 seconds to pop up the window (or dialog if I double-clicked on it). My theory is that it has something to do with the DVD drive being asleep to save power and the system taking longer to recognize that fact.

I have this problem as well, with a Lenovo T400s model 2801-CTO. The speed of the Safely Remove Hardware function is resolved by opening Devices and Printers first, but the Devices and Printers is slow. There is a suggestion to set the default printer to the Microsoft XPS Document Writer, but that suggestion doesn't work on my PC. I have noticed when searching the internet for solutions that the only people that have this problem are using ThinkPads - so I'm hoping that Lenovo post a solution soon.

Hi, this is a known issue of Lenovo Windows 7 preload system.
Windows 7 Lenovo preload
It will take longer time to show a list for removal device candidates than previous OS, when clicking "Show hidden icons" from task tray then clicking "Safely Remove Hardware and Eject Media".
Cause of the issue:
Windows 7 will start to scan some files in folders when click "Safely Remove Hardware and Eject Media". Due to this scanning process, it takes times to prepare a list of devices.
How to solve this problem:
Eliminating number of unuse files will shorten the scanning process.
There are lots of files for national language support of the Windows in
Usually in C:\ProgramData\Microsoft\Windows\MetadataStore. It carries various icon data and resource data for displaying in some managing process such as defining printers.
There are "READ ONLY" folders like following:
cs-CZ for Czech
da-DK for Danish
de-DE for German
el-GR for Greek
en-US for English
es-ES for Spanish
fi-FI for Finnish
fr-FR for French
he-IL for Hebrew
hu-HU for Hungarian
it-IT for Italian
ja-JP for Japanese
ko-KR for Korean
nb-NO for Norwegian
nl-NL for Dutch
pl-PL for Polish
pt-BR for Portuguese (Brazil)
pt-PT for Portuguese (Portugal)
ru-RU for Russian
sl-SI for Slovenian
sv-SE for Swedish
tr-TR for Turkish
zh-CN for Chinese (Simplified, PRC)
zh-TW for Chinese (Traditional, Taiwan)
Each folder carries 24 device metadata files except en-US carrying 26 files. Those file name will be "hexadecimal numbers".devicemetadata-ms.
Depends on your computing environment, there may be some language folders never used. Removing those folders and files will speed up scanning process remarkably.
Note: en-US folder should not be removed. There are commonly used files in other language.
Since those folders are read only, a following dialog will come up with attempting delete a folder. Click "Continue" button will delete a folder. If you need a administrator access to delete, please consult your system administrator.

In my laptop T410 with Windows 7 professional OS, only 3 files are present in the C:\ProgramData\Microsoft\Windows\DeviceMetadataStore\en-US folder. I have removed all the other folders in the 'C:\ProgramData\Microsoft\Windows\DeviceMetadataStore' directory. Still the remove USB media takes about 15-30 seconds to pop up the list of removable media.
Let me know if there is some other way to fix this.
PS: My friend got a new T420 and in his laptop, the remove USB media works very fast (~2 seconds).

I would like to thank user summerxia for his proposed solution.
I had this problem of VERY SLOW response on a Thinkpad X200 tablet (running Windows 7 64-bit) when I clicked the "Safely Remove Hardware and Eject Media" icon in the system tray (it would take nearly 45 seconds even with a 7200 rpm disk drive). After *moving* all of the metadata folders (except for en-US) to a different location on my disk (NOT wanting to *delete* these folders so as to avoid causing other problems if they were needed for something else), the "Safely Remove Hardware and Eject Media" option now pops up in 2 or 3 seconds.
I also have this slow response problem on an X61 tablet that too is running Windows 7 64-bit. I will report back later if this same solution works on that machine as well.
I hope others who have wondered about this slow response problem on Thinkpads running Windows 7 are able to find their way to this thread.

If you are unable to eject media, look at http://blog.notfaqs.com/2009/10/win7-safely-remove-hardware-and-eject.html for one reason for this to happen and how to fix it.
