Hi

I'm desperately need a cure for my external hard drive. I have a 250gb Seagate hard drive inside a Multimedia Maddog external enclosure. Both the hard drive and the enclosure manufacturers doesn't provide any drivers. After I plugged the USB 2.0 enclosure cable into my front Dell Dimension 4550 USB ports and the enclosure AC adapter into the wall outlet. The hard drive seem to be working properly however I could not find the hard drive icon on my computer nor under Computer Management. The weirdess thing is on the right lower corner of the window there is a Safely Remove Hardware icon, from my experience this icon represent hardware like flahdrive, mp3 player, or anything that have a usb connection. Do you have any ideas what is the cause behind all this? Thankyou

Presence of the Safely Remove Hardware icon shows Windows has enumerated something on the USB bus, but the absence of a drive in My Computer means Windows isn't exposing a usable volume. That can come from several distinct causes: the enclosure's USB<->drive bridge failing or presenting the device as a non‑volume (some enclosures expose a virtual CD or a proprietary device), a damaged or non‑Windows partition table (RAW, ext2/3/4, HFS), a duplicated disk signature/letter conflict or the disk being taken offline, or a hardware fault in the enclosure or the disk itself.

Practical, non‑destructive checks that narrow the problem (avoid initializing or formatting if data is important): try a known‑good USB cable and a rear motherboard USB port (front ports sometimes under‑power or have flaky wiring); attach the enclosure to a second PC to confirm whether the same behavior repeats; inspect Device Manager for entries under "Disk drives" and "Universal Serial Bus controllers" and note any warning icons or device names; if the enclosure has detachable internals, remove the drive and connect it directly to an internal IDE/SATA port or a different USB‑SATA adapter to determine whether the drive or the enclosure bridge is at fault.

If the drive appears but shows as RAW, unallocated, or has no drive letter, do not Initialize or Format when preserving data. Use a read‑only approach first: boot a Linux live USB to see raw partitions and copy files, or create an image of the disk before attempting repairs. Tools such as TestDisk can recover partition tables; ddrescue (for imaging) or professional recovery should be considered for failing hardware or clicking drives.

This builds on 's and 's suggestions: useful follow‑up details to include in the thread are whether the drive ever worked, the OS and service pack, what exact entries appear in Device Manager and Disk Management, and whether the drive spins or makes noises — those facts point quickly to enclosure vs. drive failure.

after you plug it in, what do you see listed in device manager?
do you have network drives?
what version of windows is this?

right click my computer > manage > device manager
do you see anything with a yellow ? or something. can you list the items you see in there?

also move down to disk management (its under storage)

if you have networked drivers, some times windows assigns the new drive a letter that allready exisits as a mapped drive. do you see any active partitions that do not have a drive letter or share a drive letter? if you do you can click change drive letter. select a letter that is not in use.
(this is very common in windows)

you could also try clicking on safely remove hardware and eject it. then plug it back in again and see what happens.
