External Harddrive in Device Manager but no where else

Hey!

Long story short, my Western Digital Premium ES 500GB External drive was about to die. I was getting Delayed Write failure errors, so i ran chkdsk. That came back with errors.

So, i pulled all the data off the drive, and reformatted. About 80% through the reformat the PC froze... So i restarted explorer.exe, getting rid of the freeze, but the Windows reformatting progress window didn't reappear. So, i left it overnight (thinking that was plenty enough time to do the last ~20%).

Now i can only see the drive in Device Manager (correctly identified and appears to be working fine). But, i cant see it in Explorer or Computer Management. I took out the USB cable and then reconnected it and got the "installing device" popup in the task bar, completing successfully but changing nothing.

Any ideas how i can access the drive to format / chkdsk it again? Acronis Disk Director doesn't see it. I put in a Vista install DVD (im on XP), and the installation wizard found the drive (but showed it as having 0.00MB). Western Digital Diagnostics also reports an error with the drive.

Where do i go from here?

Thanks for the reply.

WD CD? Ive installed the Western Digital Data LifeGuard Diagnostics, and it shows the drive as an unlabelled USB device with 0MB capacity. If i try to run any tests with it i get a "Cable test:: Read diagnostics sector error"

Any link to this WD CD?

You should go to the install portion on that CD. There it should allow you to install it and format the drive.

The fact that Acronis doesn't see it sounds bad. Are you sure it's been assigned a drive letter? Check in start->run->compmgmt.msc. You should be able to see a partition, which may just need to be assigned a drive letter before it shows up in my computer.

You probably corrupted the disc when it froze formatting, you just need to go to start, run, diskmgmt.msc and look for the drive, right click on it and delete the partition thats already there, then right click and click create partition.

Thanks for the responses.

+Gary7 - I really cant find any reference to a boot CD... just in Windows diagnostics.

rashidkaviani - I ran Ubuntu 8 and GParted didnt see anything.

+Echilon / Richard Hammond - The drive is not visible at all in Disk Management.

Cant believe that the 1 year warranty ran out on the 28th August... just when i started having problems. Should have RMA'd it straight away instead of trying to fix it myself.

Any more ideas...? Its getting a bit desperate...

On the Western Digital CD that you have there should be a section that will install the disk. You have to boot off of it. Change the boot selection in your bios to boot off of a Optical Drive. Then go into the installation part on the CD. and install it. It will allow you to wipe it, format it, partition it. If you can't accomplish this, go out and buy a new drive. I have had great luck with Seagate. There also is a program called SPINRITE that may help.

    • The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months

      By sphbecker · Posted

      Glad these prices are starting to come down, but that is still crazy. I bought the 2TB 9100 Pro (slightly more expensive version with PCIe 5.0) last year for $240.
    • The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months

      The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months by Sayan Sen Yesterday, we covered a really good deal wherein you can get a 4TB TeamGroup T-FORCE G50 NVMe PCIe Gen4 SSD for a low price of just $400 with a special discount coupon. That's just $100 per TB, making it a very good offer during these hard times. The deal is still live, so you can check it out in its dedicated article here if you do not want to miss out. Meanwhile, if you don't have that kind of budget but still wish to buy an SSD for a good price, the 2TB variant of the TeamGroup SSD at $280 its lowest price in over three months. Meanwhile, those seeking 2TB but faster performance can check out Samsung's 990 PRO, which has hit the lowest price also in the last quarter or so, as it's on sale for $370 (purchase links under the specs table down below). Thus, you want a faster drive, get the 990 Pro, or you want more capacity, grab the TeamGroup 4TB linked in the first para. The 990 PRO is a PCIe Gen4 NVMe SSD and still one of the fastest drives available today for under $500. Speaking of fast, sequential reads and writes are rated at 7450 MB/s and 6900 MB/s, respectively. The random throughputs for reads and writes are 1400K IOPS and 1550K IOPS, respectively. The 990 PRO is based on Samsung's 7th Gen V-NAND flash, and it too is TLC. It packs 2 gigs of LPDDR4 DRAM cache, which helps the random performance. The endurance rating for this is 1200 TBW (terabytes written), which should be sufficient for most users. The Samsung 990 PRO is compatible with the PlayStation 5, but if you are going to use the 990 PRO on a PC, check out the Samsung Magician app that lets you track your drive's health, update its firmware, customize various settings, and more. The tech specs are given below: Specification TeamGroup T-FORCE G50 2TB Samsung 990 PRO 2TB Interface PCIe 4.0 x4, NVMe 1.4 PCIe Gen 4.0 x4, NVMe 2.0 Form Factor M.2 2280 M.2 2280 Controller InnoGrit Controller Samsung In-house Controller NAND Flash 3D TLC 3D TLC DRAM Cache None (HMB supported) 2GB LPDDR4 Sequential Read (Max) 5,000 MB/s 7,450 MB/s Sequential Write (Max) 4,500 MB/s 6,900 MB/s Random Read (4K) Up to 600,000 IOPS Up to 1,400,000 IOPS Random Write (4K) Up to 700,000 IOPS Up to 1,550,000 IOPS TBW (Endurance) 1,300 TBW 1,200 TBW MTBF 3,000,000 hours 1,500,000 hours Operating Temperature 0°C to 70°C 0°C to 70°C Storage Temperature -40°C to 85°C -40°C to 85°C Shock Resistance 1,500G / 0.5ms 1,500G / 0.5ms Heatsink Patented Graphene Heat Spreader No Get them at the links below: Samsung 990 PRO SSD 2TB (MZ-V9P2T0B/AM): $369.99 (Sold and Shipped by Amazon US) TEAMGROUP T-Force G50 2TB SSD (TM8FFE002T0C129): $279.99 (Sold by TeamGroup, Shipped by Amazon US) Good to know This Amazon deal is U.S. specific, and not available in other regions unless specified.

    • UK to ban under-16s from social media following a six-week trial with teenagers

      By FloatingFatMan · Posted

      And here goes the "Won't someone think of the children" brigade. Get stuffed mate. This has NOTHING to do with making the internet safe. It's about tracking adults, spying on your online activity, and sending the boys around when they don't like something you post. Also, again, parliament have voted TWICE against this, and Starmer is going ahead anyway. THAT is anti-democratic bullsh**. They will use this law to track you, they will use this law to control you, and they will use this law to punish you if they don't like what you do, even if it's legal. And your data? Say bye bye to that. It'll be on the darkweb in weeks. I'm not some rando online. I've been an IT professional for 40 years, many of it in security. I know exactly what this means and what will happen to your data. I do not consent and I will not comply.

      By sphbecker · Posted

      "...but it may not be Microsoft's fault" seems like a reasonable way to tease what is going on without leaving the user with a false impression that an update is the problem. A title isn't a summery, it is meant to entice the user to read the article. It should not contain a misleading premise; which this title does not. You could maybe complain that the first paragraph should have included that detail. The writing style popularized over 100 years ago in newspapers will cover the most important information as soon as possible with details and nuance added later; the idea being that with each new paragraph you have less of the reader's focus.
