Partition / Drive Intermittently Read Only?
Feb 18, 2011
I have a pair of WD 500GB drives in Raid0 array with the resulting >900Gb partitioned such :
C: Priamry 100Gb - Windows 7 64bit
D: Primary 80 GB - Windows 7 32bit
E: Primary 40GB - Windows 7 32bit
R: Secondary Logical - 355GB - Data
Z: Secondary Logical - 355GB - Data
Using DualBootPro to boot between the various OS Both the Windows 7 32 bit installations give me no problems whatsoever, however, intermitantly when booting into the Windows 7 64 installation sometimes the R drive will appear as read only, or the Z drive will appear as read only or they are both OK.This is more an inconvenience than a major disassater, as a reboot normally resolves the issue. This appears to be cmpletely random, as it does not happen specifically after a boot into either of the Windows 7 32 installtions, but can occur even after a previous successful boot of the Windows 7 64 installation.

I have this Toshiba 640Gb HDD. I partitioned it into three logical drives. When I inserted the hdd in my xp, one drive cannot be read. Later when I used again the hdd in 7, it says that one of the drives needs to be formatted (the one that can't be read by xp). I did so but I noticed that the drive letter changed. Series of switching between the two OS, the drive's letter continues to change upon formatting. Then to arrange again the drive letters in their alpha list, I used Easeus Partition Master to change the letters of the partitions back as F, G, and H. After the process, when I inserted the hdd, it took significant amount of time for the drive to be read.
Is there any way to revert and restore the drive letters of the system? I've tried to restore from backup but to no avail.

I assume I have a trojan which replaced a certain windows core DLL by a modified version.When I list all files in a directory (e.g. C:widnowssystem32) in Windows Explorer then certain files are not visible.Yes, I checked unhide hidden files on unprotect system files in WinExp options.So actually ALL files must be visible which is not the case.Is there a win-explorer-like tool which does not use this faked win

How can I access a system partition to read and copy data? Two partitions were merged together and ended up as a system partition. All of my data files are in there.

I created a 20gb partition on my external hard drive and no longer require the partition. It is currently unallocated space so I want to format it into NFTS. Using computer management the partition was selected and and I went through the steps to format but i keep on getting an error message saying there is not enough space on the disk to complete this operation.

My Optiarc DVD RW AD-7203A drive refuses to recognize any sort of media I put within it. I am unsure of when this problem occured (because I rarely use the drive, which begs the question of how in the world can it stop working), but I do know that nothing I have tried has helped me.I've tried all of the following:Editing the registry to no avail because the "Lower Filters" key is not present, therefore the kb article is of no use.Uninstalling/reinstalling the drive Changing the Start key in the registry to "3" Formatting the entire machine and restoring to factory settings The thing is, whenever I enter the Device Manager to check on the drive, it keeps saying it's working perfectly/drivers are up-to-date/blah blah blah. I've tried searching everywhere but to no avail, and I may soon just take a hammer to it and be done with this crap.However, I am hoping that you mates can help me before rage takes over and I smash this thing to bits! Also, is it possible for a drive to be stuck in "burn mode" (as in it thinks it's always burning a cd/dvd)?

Recently my DVD burner does not see any DVDs on my computer that I built a couple of months ago. It does not see Movies, Games(that are DVD), Blank DVD-R or DVD-R that I have written information to. I have put in a few different CDs(Game, Audio and Data) and they do get recognized by the drive. My problems all started when I was writing to a Blank DVD. While it was burning, the burn process failed about midway through. After that happened, my problems with the drive not recognizing the DVDs started.
I had done a system restore to an earlier restore point before I had the problems with the drive, but that did not help. So, I undid the system restore. I have also tried uninstalling the drive from the Device Manager and restarted, but that also did not work.
The computer is running Windows 7 Professional 64-bit. The model of the DVD burner is a LiteOn iHAS524-T98 B. The Manufacture Date of the drive is April 2011, so it's not that old of a drive.

I have an Asus M3A76-CM MB with 6 available SATA ports...here is what is being reported in device manager:
ST31000333AS
Location 0 (Channel 2, Target 0, Lun 0)
ST31000340AS
Location 0 (Channel 0, Target 0, Lun 0)
ST32000542AS
Location 0 (Channel 1, Target 0, Lun 0)
in physically looking at the MB, I see that the SATA cable for the 542 is in the 3 position (facing the MB looking down), but is there a way to determine which drive is C: and what is D: (the 542 is being assigned F:, and the CD/DVD is E.

If I plug my flash drive into my PC using Windows XP, it works fine.No problems.But when I plug it into my laptop, using Windows 7 it will not load it.It says newhardware detected, installing new hardware, Hardware installation failed.If I go Device Manager, It is listed under Unknown Devices.I have tried to uninstall all the USB Root Hubs, Restart the computer, in-order for it to auto re-install with the USB in / out of the computer. But it still fails.

I found one thread on here where someone had the same issue, and there were links to two "Fixes" ...one of them worked for the CD I inserted during the process..it showed up in iTunes in everything. When I took the CD out and tried to put it in a new one, it went back to the same thing - saying there is no disc in the drive. I tried running the fix again and this time it keeps saying not fixed. I was so excited because it looked like it worked, but no. The computer says that the drive is working properly, but obviously it isn't. HP wants to charge $60+ to fix it because it's a few months out of warranty.

I have to remove the "Read Only" status from my external USB WD 2TB hard drive which I used as a backup drive. I have tried all suggestions here and in other forums. None have helped. I'm using Win 7. I will be returning the drive to the manufacturer (WD) and I want to (Format) erase all the information on it. All my tax returns information as well as my Quicken data have been backed up to this drive

I cant burn dvds on my hp dv7. I use Win 7 64 bit Home Standard edition. I have owned this computer 3 years now and since my free upgrade from Vista to Win 7 the problem has existed. As far as I can tell the filter trick only works for one or two of these machines, and will only really help the problem when it first manifests itself with burning issues. One day your filters will just break in the registry, and at this point the problem becomes unsolvable, even by changing out hardware, or uninstalling and reinstalling old hardware. It would be nice if someone other than Microsoft or HP would look into this or that said companies would make a real effort to figure out if the problem is an interaction between the firmware and the registry or the driver cache and the registry. I fix networks and computers for a living, and am working on my BSIS in Technology Management?

I have an Acer Aspire One Happy and have got this message:
"A disk read error occurred Press Ctrl+Alt+Del to restart"
I have been searching for solutions all day but I can't do any of the options described. Pressing f8 to enter safe mode does nothing, nor does alt+f10. I also don't have a cd drive as its just a netbook and no recovery cd came with it even if I did have a portable one. Anyone have any ideas? I'm on a boat in the Arctic for the next month and without my laptop I will likely jump off an iceberg!

I have bought a used computer having windows 7 installed. It had a Hitachi LG combo drive, but it was not working, so I replaced it with a Samsung one. I have checked it on another computer. It was working fine there but it is not working on my PC. It does not show any exclamation mark in device manager. It just read the cd/dvd but does not respond. I have already done with the registry fix and also tried the auto fix from Microsoft site, but nothing worked for me.

OK so since I have installed a fresh copy of Windows 7 on this computer ( it is the first operating system installed on it) I can not write any DVDs .A strange fact is that I can write and read CDs and also read DVDs, but not every time.I got an original CD Album and it's still not recognized by the PC for example, and this happens to many audio CDs.I tried many registry tricks and stuff like that but in vain.The computer is new, bought it one month ago. DVD+RW - Sony Optiaric AD-7260SI also tired to resolve the problem with FixIt but it was also useless.I kept getting the message: "The disc in drive [E:] is not detected, or is not supported"

Ive had this problem once before. I turned my PC on Yesterday, and my WD 500GB Hard drive (Number 3) was not recognised. Then I did a reboot, and the drive showed up again, HOWEVER, The drive has the Read Only flag in DiskPart and using the attrib disk clear readonly commands with the correct disk selected does not work. DiskPart just moans that It cant clear the attribute.
I doubt its a Driver Issue or a Hardware issue as It was working fine. All the tests in Ubuntu 10.04 (my second os) come up good and I can write to it, So Windows 7 has done something, Not sure what.

So i build a newcomputer yesterday. I decided to use my old SATA hard drive from my computer, it has my OS, and other files on it. I get everything put in, but when i start the computer it says "no hard disk is detected".
I enter the bios menu, and i notice it recognizes that it is in there, as well as my disk drive.
How come it wont let me load my hard drive, and it doesnt detect it when i start it up.. but BIOS sees that its there?
