Hello…

 

I have several HDD of 2TB and 3TB, all of them aren't connected, I only use them once in a while (usually), when I want to connect one of them I use an external enclosure and it works fine, but yesterday and about two months ago two of my 3TB drives just weren't more recognised, I formated them and now they're OK and work fine, but I loosed all the data that were in there, I did try to recover the data but the names of the files were 01, 02, 03, etc and the name of the files were very important.

 

Until now not one of the 2TB drives fail, only two 3TB, could the problem be in the controller of the external enclosure? Is it possible that it only "works better" with 2TB?

 

I just buyed an external HD (3TB) and now I'm using this controller with the 3TB HDs and the old controller with the 2TB drives.

 

Am I doing the right thing?

 

Thanks!

I have a friend that works at a hosting company and he also was using WD 3TB Green and the same was happening to him, then he started to use WD 3TB Red (just 5€ more!) and the problems stopped.

for recovery.

 

Recuva

http://www.piriform.com/recuva

 

do a deep scan, in the options there is a setting to find file paths aswell.

 

3TB drives are a bit of a nightmare, not everything is compatable with them, it might have been down to the actual hardware inside the enclosure you were using not being comatable with more than 2TB, slightly over it. operating systems also have an issue with anything over 2TB, it's a hardware and software issue (motherboards bios sometimes need to be updated)

 

the problem might also have been caused by you removing the drive whist it was writing, or just a random error that caused the drive to be unreadable, this can sometimes happen with driver issues.

 

i have a external 2TB on a seperate USB 3.0 expansion card, and it will come up with a simular problem, will request formatting, sometimes show no files and sometimes only folders. this is caused by a faulty USB cable and poor drivers.

I did use a recovery software and I think it showed all the files that were in there but there where no names on the files, and that was a big, big issue in this case.

 

I'm very careful about dismounting HDDs, I think this isn't that case but since I use a lot the USB drive with lots of HDDs that might be the problem.

some programs are better than others, i've tried a few, some you have to pay for like GetDataBackNTFS (nto sure if there is a free version) but Recuva is just as good and should get the names and directories the files were in back as well.

 

have you ever thought of using a hot swap bay? might be better than enclosures.

This is due to the limit of the MBR partition size limit, which is 2 TB (512 multiplied by 2^32).

If you have discs that large then you should convert to GPT.

You can convert from MBR to GPT in Windows by using the command line utility called DISKPART. (WARNING! Converting will erase everything on the disk)

Updating the motherboard firmware is always recommended but converting to GPT and booting through UEFI instead of BIOS should be a high priority for anyone with a modern PC.

I convert ALL storage devices to GPT except flash memory used by portable devices, including a 32 GB memory stick and my 120 and 240 GB SSDs.

More information and operating system support for GPT is found here: http://en.wikipedia....Partition_Table

In other words, never buy disks larger than 2 TB if the installed operating system is too old.

Thanks for all the answers, unfortunately this happened about 2 weeks ago and I formatted the HDD :(

 

I'm gonna try the Hot Swop Bay.

It happened again! With the same HDD, I'm gonna deliver it.

 

I run Ubuntu Live CD with the HDD mounted and it recognised it without problems. Does the latest Ubuntu writes to NTFS?

 

Does this indicates a problem with the HDD or with Windows?

New update.

 

I placed another HDD and the same problem! I did some testing and the problem is in the SATA port.

 

I already tried with 3 HDDs in the new Port with the same cable and now everything is working fine :)

 

I was about to loose my faith on computers  :wacko:

 

I did recover all the data on the 3 HDDs, just loaded Ubuntu Live CD and then restarted with Windows. Simple but it almost made me pull my hair  :shiftyninja:

 

Thanks for all the help!

Green drives=Bad bad bad! Tons of hosting companies have issues with them. They get extra stressed from constantly being power state altered. They do that to "save energy" however they are rougher on the drives, and not very trustworthy.

 

Not worth loosing data over. 

 

I would also recommend NOT  using software RAID. I would use a good 3ware LSI RAID controller or don't RAID at all. 

 

Softraid also causes tons of problems.

I always used the WD 2TB HDDs Green and they're flawless, I've about 16 of them, and never gave me any problems, but the WD 3TB HDDs Green...
