HDD Underpowered? Drive sometimes appears, sometimes doesn't..

post #1 of 12
Thread Starter 
I have a total of 1 SSD and 2 HDD in my computer.

SSD: OS
1st HDD: Main usage
2nd HDD: Backup storage

The 2nd HDD was from this "external" HDD. I purchased an internal HDD few years ago and snug it into a portable case. Hardly ever bring around though..

Just early this year I got my new desktop, so I decided to place it in my desktop. Sometimes I see it appear in "My Computer" but sometimes I don't. When I don't, I only realise I can see it again when I happen to restart my computer and happen to open up "My Computer".

I can still read and write on it when it appears but its not always there..

All other drives/ssd and other hardware working fine. I'm wondering if it is my PSU that is not sufficient? 750W quite high right lol. What could be the problem? How do I solve it?

By the way, my desktop power is taken from an extension, and not from mains. Could this be a problem as well? :x

There's a reasonable chance something could be failing, either the drive or the cable or the port on the mobo. I'd suggest getting any data you want off the drive just encase it's that that is on its way out. I'd try swapping the cables and ports - if it acts the same with those changed it's most likely the drive dying, I've had one with those same symptoms and it didn't last very long.

Roger that. Gna have to shop for a new drive to transfer the important stuff over!

Any 1TB and 2TB HDD to recommend? Speed isn't much of an issue for me since I'm using this as a backup drive but of course it would be a plus if the speed is good too! I'm more concerned with reliability in terms of firmware or just hardware issues.

I'm thinking WD Green..what do you recommend?

hey Kooosh, I not so long had a drive go bad on me with the exact same symptoms you are describing, a friend told me to get HD Sentinel, you can get free trial from here, Hard Disk Sentinel Trial v4.10 (ZIP):-
http://www.hdsentinel.com/download.php
On my bad drive it was all red and performance was at 5% indicating imminent death. Be sure to do a backup.

Manufacturers have tools that can run internal drive diagnostics (extended SMART tests) to determine whether drives are failing. No need to download trials or buy software - it's free from WD/Seagate.

http://support.wdc.com/product/download.asp?groupid=612&sid=3
http://www.seagate.com/support/downloads/seatools/

In the 1TB range, the WD10EZEX can't be beat. Acceptable warranty (2 years), great speed, good noise levels. Probably more reliable than Green drives. thumb.gif Right now you can find them for $69.99 with free shipping.
http://us.ncix.com/products/?sku=74462&vpn=WD10EZEX&manufacture=Western%20Digital%20WD&promoid=1230

In the 2TB range, I'd be looking at the new Seagate drives or WD Reds.
WD20EFRX - $110: http://www.newegg.com/Product/Product.aspx?Item=N82E16822236343
Seagate 2TB - $90: http://us.ncix.com/products/?sku=66010&vpn=ST2000DM001&manufacture=Seagate&promoid=1230

WD Reds have a 3 year warranty, high sequential speeds, very good noise levels, and are probably more reliable than Green drives.

The new Seagate drives have 1 or 2 year warranties (depending on batch), higher sequential speeds, and some hum loudly or chirp. (1/4 chance of getting a noisy one? tongue.gif ) Reliability is likely on par with Green drives, but the price is lower.

Thanks a bunch Kramy!

I think the WD Reds is a worthy buy and is what I'm looking for! thumb.gifthumb.gif

Just got a new 2TB WD Green HDD and plugged it in only to experience difficulty accessing a folder in the faulty drive (wanted to go in to see what files are in it before cutting and pasting it onto my new drive) and My Computer didn't show it after that error. Now after two restarts I still can't get it to show. What should I do now?

Here's the sequence of events.

1. My Computer intermittently displays the faulty drive.

2. I unplugged the faulty drive and used a single dedicated Sata power cable from the PSU. Then shifted the Sata data cable from the original to another port on the mobo. My Computer detects and displays for two restarts.

3. Went out to get new HDD for backup. Plugged in and started backing up a few folders.

4. Wanted to enter into a folder to see its contents, experienced an error about permissions.

5. X'ed out the error and Explorer couldn't find the drive anymore.

6. Restarted but still unable to display. Twice.

What should I do now?

Unfortunately Kramy, Seatools still said my HDD was 100% fine and passed all SMART tests, long and short and even a full surface scan from the bootable .iso still said it was fine when it clearly wasn't, so I wouldn't trust Seatools completely for HDD health. HD Sentinel on the other hand instantly saw the problems which is why I recommended it. Luckily the Seagate drive I had had about 12 days left before end of warranty so was replaced. thumb.gif

Kooosh, It sounds you have read/seek errors which is causing the permissions errors you are seeing, I had the same thing. It also sounds like the drive is suffering from grown defects which I can tell you will only get worse the more you mess with it. If the data on the drive is critical I wouldn't run any more diagnostic tools on the drive and move straight for a data recovery program like "Get Data Back" I have had great success with, there are also free ones like "Undelete Plus" This will read the drive one time at low level, extracting data from the MFT and creating a filesystem list from which you can then extract all or parts of the data you want to recover. Luckily you are still at the stage where windows can still intermittently "see" the drive so data recovery should be quite simple.

Good luck thumb.gif

Accessing a dying drive while it's copying stuff is a big no-no.

I'd probably jump directly to using ddrescue to salvage stuff, but if you aren't familiar with Linux that can be a steep learning curve.
