Checking Drives for errors and difference between portable and large external drives

Q: Checking Drives for errors and difference between portable and large external drives

I was wondering what the best way to make sure your external drive is functioning as it should?

Also, how much damage is done if your drive loses power abruptly?

Also, why would someone want a larger drive that needs an additional power source compared to a portable drive?

Preferred Solution: Checking Drives for errors and difference between portable and large external drives

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Ok mate try one of the hard drive testing tools Seatools SeaTools for Windows | Seagate

plus the disk surface test with the Partition Wizard Best Free Partition Manager Freeware and free partition magic for Windows 7, Windows 8, Windows Vista and Windows XP 32 bit & 64 bit. MiniTool Free Partition Manager Software Home Edition.
click on the drive you want to test click on surface test and then Apply at the top it might take some time to do with a large drive though.

Personally I don't like large drives for this very reason ls it and you lose a lot.

The power source is self explanatory really it is probably because the power required via the USB connection is not adequate to run the drive.

As for data loss in a power outage well once it is up and running just go through the data and see for yourself.

I have a Seagate Barracuda 250GB drive that I cannot get to work in my HD Enclosure.

Someone said the enclosure must support Large Drives (48bitLBA).

I have an inexpensive Nexxtech enclosure. It is only a few months old. However, I can't find any info about whether it will support the drive. Can't even find the model number.

BTW, the drive contains data in three different partitions. It was installed internally on my wife's old computer.

Anyway, most enclosures don't even say whether they support larg drives.

I'm running WinXP-Home SP2.

Any suggestions?

Thanks,

I had posted this on another thread concerning a blue screen in a Sony Vaio but was advised to remove it and start a new thread which I?m doing here. I have a two year old Sony Vaio 64 bit with Windows 7 Home Premium, Service pack 1. I had no problem with it until I put on Norton 360 when blue screens started generating. I posted on here a week ago and uploaded a zip file and followed the advice given after analysis.
I got onto Norton Community as advised and uploaded the contents of the BSOD screen which only occurred when I started the computer. They gave me a link to a Microsoft Knowledge base article at http://support.microsoft.com/kb/979444 which in turn led me to the following hotfix :- http://hotfixv4.microsoft.com/Windows%207/WindowsServer%202008%20R2/sp1/Fix302249/7600/free/404162_intl_x64_zip.exe
I downloaded this Hotfix and got no BSOD for a week when I got another one. The contents of the BSOD screen I got after one week were as follows:-
A problem has been detected and windows has shut down to prevent damage to your computer.
APC_INDEX_MISMATCH

If problems continue disable or remove any newly installed hardwear or softwear. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer press F8 to select advanced start-up options and then select safe mode.

This past September (2011), I discovered one day after a series of unexplainable issues with a restored file, that a number of backup copies of large files on external USB-connected NTFS drives differed from the source versions still on my hard drive. I also discovered that I could reproduce the issue with newly-copied files.

Here are the specifics of the issue, following a series of experiments:
- On my system, copies of large files, files typically larger than 500MB, are corrupted (altered) roughly 30% of the time when copying them under Windows 7 64-bit to USB-connected NTFS-formatted external drives.


- No error occurs / no error message appears during the copy



- The file size of copy is always identical, whether or not data was altered during the copy process.



- File differences are confirmed via either the command-line "FC" command or a utility such as WinDiff


- The issue impacts copies made via the Windows GUI -OR- via command-line copy or xcopy


- The issue occurs with multiple external USB NTFS-formatted drives, no matter what make or model.


- Subsequent attempts to copy an affected file will ultimately yield an identical copy. This would seem to rule out interference by an external program such as an anti-virus program (and the only AV I am running is Microsoft Security Essentials)


- The USB drives involved pass error checks, and copies made to these drives on other (non W7) systems produce identical copies

- So far, the t... Read more

A:Windows 7 64-bit Corrupting Large Files Copied to External NTFS Drives

I've seen this problem. I downloaded a large zip file and copied it to an external drive. When it was done copying I opened the copy and discovered the corruption. I returned to the original file and discovered it was not corrupt. My second attempt worked fine. I seldom work with files this large so this is the only data point I have. I'll create some large archives and try it a few times over the next few days.

Hi, I have an HP Windows 10 laptop that I bought last year. I burn DVD-Rs and BD-Rs quite frequently, both data and video. Anyways, in the past month I all of a sudden started having problems. No matter what software I used or type of authoring, (video DVDs or Blu-rays through Cyberlink Powerdirector and Pinnacle Studio, various iso burners, data discs through Windows own disc burning software), I will often get error messages and end up with an unusable disc. Once in a while it will make a mistake and actually work but most of the time it won't. I thought it may be the external BD-R drive I use most often, but I have the same problem burning DVDs with the laptopslown drive. I also don't think it's the blank media's fault, as I've used various brands which get good reviews, and I've used them for many years with no problems. I did a restore point in case that would help but it didn't. I am just about at the hair-pulling-out stage. Any insights? Thank you!

Yesterday I discovered my computer will no longer read my flash drives, external hard drives or SD cards.  If I plug in any of them, they don’t even show up in Disk Management.  In Device Manager they will show up, but will have a yellow flag and under Properties it says the driver for this device is not installed even though they’ve been used before on the computer.  Clicking “Update Driver” doesn’t help because it searches and says there are no drivers for this device.  If I go to the “Events” tab, it gives the  date and “Device configured (null)”.
 
I restarted my computer today, hoping it might correct this problem, but when restarting I ended up with a message about an inaccessible boot drive.  After going into a loop several times where it told me about the inaccessible boot drive and then restarted again, I finally ended up with a screen that gave me more options for troubleshooting such as doing a system restore point.  I had the computer perform a system restore and finally it took me to the welcome screen and then desktop.  Anyway, rebooting did not correct the problem about my computer not reading my flash drives, external hard drives or SD card.  Any ideas?  Maybe the problems I’m having are related to a recent Windows update (computer seemed to be working fine before the update), but don’t know for sure.

I am running Windows XP SP3 right now on a Lenovo 7650-ELU and experiencing some odd problems. For some reason, the laptop I have will not recognize USB Flash Drives that I put into it or External Hard Drives. I know that the USB ports work correctly, because I have plugged in optical mouses and keyboards that work. I searched the forums and didn't see anything like this.

It's odd how when I first insert them, it makes the sound and shows the icon in the taskbar that would allow me to safely remove the device, but nothing else. So far, I have gone into the device manager and uninstalled all the USB ports and restarted hoping this would solve my problem, but it continues to do the same thing.

If anyone has some helpful advise, please post. I appreciate all the help.

I volunteer for a Charity in the main role of IT admin. Part of what I want to do is ensure the Laptops, External Drives and Memory sticks are encrypted, but I am worried if I (try to) encrypt a drive with files already on, they will get messed up. I am not an expert, so would appreciate any advice and guidance anyone can give. Any favourite products? We are a charity so want to pay little or nothing for this. The intention is to ensure any personal information we hold is secure if it falls into the wrong hands. I am clearly looking at making sure no-one uses Laptops/Ext drives/memory sticks that do not belong to the charity when working (self included), but am a little uncertain where to start with this and do not want to make things worse. Any input gratefully received. Probably a simple question for lots of you, but not for me!!
 

A:Encryption of hard drives, external drives and Memory sticks

All the encryption programs I know of support encrypting drives with data. BitLocker and Vercrypt(TrueCrypt port) absolutely do. BitLocker absolutely requires the use of strong Windows passwords as it only protects the drive if its removed or accessed via another boot device. VeraCrypt has the added benefit of having a pre-boot password so you cannot even boot to the operating system without entering the password. You should still of course have strong passwords and automatic locking of the system after a set time of inactivity.

You may also want to re-evaluate the need for USB drives and sticks, not only are they bad for data security but also easy to lose, have stolen, or just fail. Central storage and VPN access may be preferred to a giant pile of external devices that some places end up relying on.

zformer,

You can consider the use of the Panda Vaccine on your computer and USB Drives:
Download Panda USB and AutoRun Vaccine - MajorGeeks

This tool provides a two way security by vaccinating both computer and/or USB drives.
It work on NTFS, FAT, FAT32 formatted drives.
However, vaccinating a USB drive cannot be undone without formatting the USB disk, using a hex editor, or a File Manager in a Linux distribution..


Next, make sure that your Antivirus can scan USB drives. Some do not have this option.

I was cleaning a PC that was infected with a tough rootkit and eventually rebuilt w/ OS to ensure all was well. During the attempted cleaning, I had a external hard drive and a flash drive connected to the PC. My question is ... can rootkits and their similar counterparts spread to attached drives such as these [and eventually infect the next PC they are attached to]?

A:Are Rootkits able to jump to external drives or removable drives?

Yes,that is quite easy,especially with .exe files.You ned to clean the drive and scan what ever iy connected to.Were they both Win7?EDIT:You can download and use Autorun Eater or Autorun USB Virus Finder which will allow removal of any suspicious 'autorun.inf' files they find. Panda USB Vaccine. Computer Vaccination will prevent any AutoRun file from running, regardless of whether the removable device is infected or not. USB Vaccination disables the autorun file so it cannot be read, modified or replaced and creates an AUTORUN_.INF as protection against malicious code. The Panda Resarch Blog advises that once USB drives have been vaccinated, they cannot be reversed except with a format. If you do this, be sure to back up your data files first or they will be lost during the formatting process.Another option for XP users is Flash_Disinfector by sUBs. Please read About Flash Disinfector by Papakid and USB/Flash Drive Safety by TheJoker.Finally, always scan USB flash drives and any external storage media after they have been used in other computer systems, even your own. An easy way to do this is to download "ClamWin Portable Antivirus", put it on your USB Flash Drive, update its definition files and perform a scan.{borrowed from our quietman7}

Hey guys. I've been a fan of your forum for a while, and didn't create an account til now. I'm at my wits end.. and I'm desperate for help. My posts on other forums have been ignored, so I'll try here.

It all started when I bought the Dingoo A320 game system. In order for it to work with Windows 7, I had to replace the USBSTOR.sys file with another. Everything seemed fine.. except the file transfer to my Dingoo was exceptionally slow. Eventually, I followed instructions months ago, and somehow got my Dingoo to not use it's preinstalled China Chip Drivers, but Windows's mass storage driver.

Everything seemed fine for months.. until I bought a portable hard drive (Seagate Freeagent Go Flex). After spending hours trying to figure out why it wouldn't install, I returned it.. about a week later, I picked out a Patriot 64GB Flash Drive as a replacement to the Freeagent Go.

Hi

very bizarre :
- 3 of my 6 drives SATA connected to internal SATA connectors on board ( Z87 Deluxe)
- are shown in explorer "my computer" as hard disks ( while correctly DVD and USB are in removable drives list)
- however these 3 drives appear in the list of removable drives Under the W7 utility "safely remove" !

That could lead to confusion when removing removable drives !

Any explanation ? Can I correct this ?

I think that it is possible that these drives have been formatted and partitioned whiel on a SATA-to USB dock ( when PC was Under repair). Have tried to delete all partitions on one of those drives, and recreate partitions Under W7 with Acronis Disk Director, but no change.
Or should I remove them from Computer Management ?

TIA for help please !

Regards

A:SATA drives : internal appear as External drives !

It is not bizarre but a result of drives being connected to ports that allow hot swapping (set to AHCI)

One possibility is to install the Intel AHCI drivers instead of the stock drivers that are part of the Windows 7 DVD.

Another is this:

FIX: AHCI/SATA drives showing in "Safely Remove Hardware"

This works for the Intel controller.



If you are connected to another controller, go to the Device manager and right click on that controller and select properties.

Then under the Policies tab, you should be able to uncheck the box that allows safe removal.

Hi There,

I have recently copied all my CDs on to my itunes.
I'm thinking now it would be a good idea to be able to quickly back up the itunes folder.
At present I have it all on an external hard drive.
Should anything happen to this I'd lost all my music - not good.

So I'm after a portable external hard drive, approx 20G.
Doesn't have to be particularly fast transfer, as I'd only be backing up about once a week.
Also, I'd rather it be USB power based as I can't really be bothered to scramble around behind the desk plugging things in.

Any suggestions?

You have a huge pool to choose from and it keeps changing all the time.
I have a couple of little 40GB Smartdisk Firelite external drives which have worked without problems. They have both USB and Firewire versions, but I've never tried the Firewire. They run on a single USB cable but you can buy an optional mains adapter if you wish.
The only niggle was that they were both bought from Staples, a few months apart, yet they use different drivers for Windows 98SE.

Sounds like you have some security option enabled to scan removable drives. It's not inherent to Win7. Check your security suite for the setting.

Why did Newegg choose to sell the 2MB for more is a question for them. Obvisously the 8MB drive is the better buy.

I sent in a WD1001FALS-00J7B1 for RMA, WD sent me WD1001FALS-00E8B0 back...
Are there any differences?

A:Is there a difference between these two drives?

From what I've read, they are essentially the same. They only have minor hardware differences/firmware revisions.

Essentially unless you notice anything wrong with the drive then I wouldn't worry, they likely sent you an updated revision of that model.

Hey,

I just wanted to know what software is good for use on a Portable Hard Drive?

Thanks

You need to be more specific on what you mean by program. I can only guess you're talking about back-up software. The 2 more popular ones are Acronis Tru Image and Norton GhostAlso take a look at our Freeware Applications thread

I run a computer repair business, and my customers really appreciate it when coming to their homes is an option. They simply dont want to bring the tower to my home shop. As such, I thought it would be a great idea to become completely mobile, where I could carry everything I normally would need or use in a single bag to solve or repair most computer problems. This has worked very successfully, until I decided to purchase a western digital portable hard drive from ebay. Everything was fine until a couple weeks ago, when it started emitting a general clicking sound, and continuous spin and stopping sound. I hadnt even had the hard drive for 2 months yet. Obviously the last thing I wanted to hear on a hard drive (I had just backed up a customers data after reformatting their system too). Did an RMA on the thing, sent it to western digital for replacement. So in the meantime, I still needed something to back up customers data with. I bought a seagate portable Freeagent go 250 gig from walmart. Pulled it out to back up a systems files, and wont even show up when I plug it in. Listened to the hard drive up close, and sure enough its doing the same thing as the western digital drive. Just not the clicking this time. I've only had this one for a little over a week. And so, I'm in a dilemma of sorts, as what I should do about this situation. Seems to me that although portable, which is very nice, packing these skimpy portable drives in with my other gear doesn... Read more

A:Portable hard drives unreliable?

I have had this happen with my WD Passport drive if it was not getting enough power from the USB port. My university has those Dell monitors with USB ports in them and whenever I connect the drive to those I get this. The USB ports in the chassis work fine though. The drive light is usually dim if it isn't getting enough power.

Tried another USB port or cable to see if that fixes the problem?

I have always imaged my Windows 7 laptop using the in built Windows system image back up and it works great. A couple of times I have restored the image to get me out of a hole and it worked every time.

Anyway over the weekend I went to take an up to date image onto my USB 3.0 WD My Book Hard drive. I plugged the USB drive into the power strip and heard a loud bang like a balloon being burst. I quickly unplugged the USB drive. After a change of underwear I flipped the breaker back up to restore upstairs power. Everything came back to life indicating the problem must of been with the USB hard drive. But bizarrely when I tested the WD drive at another power strip it lit up and seemed to still be alive!!! So I put it down to one of those unexplained things and proceeded to start the windows image of the laptop. It took a while because it was backing up 650 gb of data and hadn't been done for nearly 6 months. After about 2 or 3 hours it was nearing the end of finishing the image backup when suddenly I got BSOD on Windows 7. Pretty annoying. I force powered off the laptop and rebooted windows. I decided to try and start the imaging off again but now the USB HD isn't detected by windows when I plug it into any of the USB ports. I tested the ports with a couple of small USB flash drives and they were detected just fine. So the problem obviously lies with the WD drive. I am just worried by the BSOD and whether that may of risked damage to my windows installation being disrupted dur... Read more

A:Are portable USB hard drives ok to use for Windows Image?

Yes, no problem. The external drives that require their own power supply are generally 3.5" drives while the smaller drives that can be powered via the USB port are generally 2.5" drives. Neither is "safer" or more reliable so it's simply a matter of personal preference which you use. As long as the smaller drive is large enough disk space wise to handle your backup needs then it is certainly much handier since there's no need to plug in for additional power.

I used to know of a security system for usb flash drives and pretty much any portable storage.

It used auto-run and a batch file to automatically send an email containing the IP address of any computer that it is plugged into(Except computers in witch you say are ok)

This way, if your flash drive is stolen and used on a foreign computer it will send you an email with the IP address of whoever stole it.

You can use their IP address to locate their location and/or report them to the police.

Unfouruanetly I cannot find the files anywhere on the internet.

If you know what im talking about and perhaps have a link to the files, please post it. Thank you.

Hi and Welcome to TSG,
I've seen such progs for laptops, for instance http://www.absolute.com/solutions-theft-recovery.asp but not flash drives. If you want to secure data on your flash drive (and keep a backup copy elsewhere) you could use the well regarded (free) TrueCrypt in 'traveller mode':

I hope this helps?

Hi there,

I have today downloaded and installed the Update Windows 10 Home 1903. It went pretty smoothly on the whole, although I had to change some of my settings and other bits and pieces I didn't like about the new set-up.

However, I have found that after the update, my portable USB hard drives and flash drives won't automatically open now. I have to find them in Windows Explorer and click on them myself. They used to open straightaway when I plugged them in. Has anyone any ideas on how to fix this.

Thanks in anticipation.

I've been receiving BSODs and after failing to resolve it, I am going to do a clean install, but I want to transfer all my files to an external which I am going to buy later today.

Regarding 1TB hard drives, are they more sensitive than devices that hold less storage space, more fragile? I have been looking at a toshiba brand and WD. Both are 1TB and have 2.0 and 3.0 capability. Despite my research and due to my indecisiveness it is hard to pick between the two. I just don't want a drive to fail on me.

Thinking more about it, would a smaller hard drive be more reliable? I am open to getting a seagate or WD at 250 or 320 gb.

I don't know too much about portable hard drives besides the obvious, so if you could help clear up my confusion, I will greatly appreciate.

Thanks!
 

A:Questions on portable hard drives (1TB and various brands)

There really is no difference in hard drive brands so I wouldn't get too hung up on which brand to buy. I don't think there is any benefit to getting a smaller drive now over a 1TB. 1TB drives have been out for a long time now, the only time you want to be a bit cautious on buying a big drive is if its the biggest that company offers at that point in time.

For example, a few years back someone (I forget who right now) made a 1.5TB drive and it released with bad firmware causing very early failures - that got 'fixed' with a firmware update, but drives still had an abnormally high failure rate so I think there was something really wrong with those drives initially. Later releases of the same drive were fine. So, don't buy the biggest you can find and things will be fine.

Hi, I have a WD My Passport Ultra portable drive which comes with password protection to secure the data in case of loss. But I also have a Seagate one which does NOT come with such a feature. Is there another method I could use to password-protect these drives, perhaps built-in to Windows 10? I would probably prefer that anyway because I don't like using the pre-installed software that comes on portable drives...

A:Is there any way to password-protect portable drives we connect?

If you have Windows 10 Pro or Enterprise you can use BitLocker.

This seems to be free:

Has anyone purchased a Western Digital Passport portable hard drive recently? The reviews I'm reading are saying that they ship with software installed that cannot be deleted and that mounds a virtual CD drive when connected. I'm wondering if perhaps these reviewers just aren't savvy in deleting partitions using 3rd party utilities or if there really is something in the firmware of the drive that causes this behavior.

Or does anyone recommend another brand for a portable drive? I need a portable drive because an external power source is not practical in this case.

I dont know about that but.............they have changed the interface to where it plugs in though.
So basically you cant take it out of the case...pull off the usb adapter and toss it in PC...or just toss it in your old enclosure.
I remember reading about it here in the forums a few months ago.
IMO this is a big deal versatility is now taken away.
My next purchase will be a seagate......only after a little research ofcourse to make sure they havent done what WD has.

For whats its worth..My hdd in my laptop right now started out as a WD passport...I took the seagate out and put it in the WD enclosure..complete with Vista still on it as well as the recovery partition.
I still use it to back up files...I just copy them over to folders I created myself....works great.

Also to consider in regard to seagate is people like the backup software if you decide to... Read more

My computer is having trouble reading more than 1 portable external hard drive at the same time.

It will read my ac powered external hard drive (3.5') and 1 other portable hard drive(2.5') just fine, but when I try to plug in two portable hard drives, my computer only reads one of them. Both drives are powered on when they connect (Both light up and I can feel both of them running), but only one shows up in My Computer.

Note: Occasionally both drives show up when I plug them both in, but then eventually one of the drives becomes unreadable; All I see are bunch of empty folders (which are suppose to be filled with my stuff).

Note 2: Both drives are western digital. I've tried a toshiba one in the mix, but still get the same problem

Anybody know what's going on? Is this common with the new usb 3.0 portable hard drives? (i'm only using the usb 2.0 ports though)

Have you tried different USB ports or tried a repeater. USB only gives out so much voltage. I still have USB DVD drives that have a double ended USB cable so it could pull power from two ports.

Hi there

IMO these portable USB3 self powered (passport) type drives are a total con with regard to performance -- I get SLOWER performance from these plugged into a proper USB3 port than I do from an older 7200 RPM Hitachi laptop drive connected to even a USB2 port via a SATA==>USB2 cable,

(Not talking about large mains powered external USB3 drives -- these work fine).

Am I alone in this or is this a general sentiment. Note the laptops I've been using have a genuine USB3 (blue) connector with two sockets on the disk end and am not using a hub.

I'm still happy to use these small drives as they are 2GB - quite a decent capacity for a portable pocket size drive - but the performance leaves me seriously "underwhelmed".

I know that 7200 RPM laptop HDD's are as rare as hens teeth these days but USB3 advertises itself as being capable of up to 10X USB 2 speed. My observation has been very different so far (apart from as I have said the full size non portable external MAINS powered USB3 drives which DO work as advertised).

Cheers
jimbo

A:Portable USB3 drives - appalling performance

The passport ones are probably those that get the 5V power from the USB port only. Bigger / 7200rpm drivers require external power supply providing the extra power mainly 12V (up to 2A) and we don't need to think twice which one of these drivers performs better.
