View Full Version : Hard drive with Blue Question Mark Win 7

23-06-2011, 01:21 PM
Hi Guys

I have Windows 7

And I just re-installed a hard drive I was suing for backs.

On my desktop, its Icon has a large Blue question mark on it.

I seem to be able to read most of the files on it.
But it seems very slow.

What is my best course of action ?

Thanks in advance

Is that suing for backs or using for backups? Is this an internal or external drive? SATA, IDE, USB?

Using for backups

It is an internal SATA drive.

I can read files from it, but copy files to it is very slow.

I can read files from it, but copy files to it is very slow.

really slow speed is a one symptom of a failing Hard Drive . May be other causes as well. Try another sata port/sata cable, reformat (NTFS) if the files can be deleted .

FYI, you definitely do not want a backup drive installed in the PC. Better to have it removable/external in case things go puff, blue smoke & all internal drives get fried. Rare but can happen.

Try another SATA port. Some ports are for hdd's / others are for DVD's / cd's

I would also check under IDE controller (in device manager, for whatever port its on). Whether its in DMA or PIO mode

Id be a bit suspect of the Hard Drive, it could be failing or not detecting correctly.

What sort of drive is it -- Not a Western Digital BLACK by any chance ??

On the less serious side :p your Computer has an identy problem -- It thinks its a MAC -- do a google search, and just about all the replies are with Blue question mark on HDD = Failing drive = MAC. :D

NO, its a Western Digital Green 1.5TB!

And yes I see what you mean about the Blue Question mark being very prevalent on Macs.

It just seems to be going so slow.

Its in the same SATA port as my previous drive and the same was this drive was in a few months ago.

It has been in an off-site storeage area.

Slow - very suspicious. Back it up and run the WD diagnostics on it.

Thanks fro all the help

I don't need to backup the data on it.

But I just want it to work properly. (ie to be able to take it in and out of a machine and let me copy files to it)

I ran WD Diagnostics, but that was a waste of time as for some reason I did not have the SMART system set up.

It reported the disk was working fine ! (dur)

As I said I can read from it, but cannot copy many files on to it before it slows down and the stops.

So I have sent it back to my supplier for a replacement.

It would be nice if all this technology worked 99% of the time.
