Partition Drives Cannot Be Read
May 4, 2011
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.

Win 64Bit Keeps making my drives Disk (Volume) attributes "read-only". I can Unlock the drives by using the command prompt and using diskpart to clear the attributes on each drive and volume, but this is tedious, and I have to do it almost every day. What is causing this and what can I do?
I have a feeling it may be related to another problem I have. I tried to change my homegroup settings but closed down my PC before it had finished making the changes. Now, when I try to change the homegroup settings all I see is a notice saying that it is still sharing my Libraries, or something similar. This message is permanent, and I can make no changes. What can I do about this issue please?

I have a problem with my PC. It is simply can't read lot of USB drive. I need to restart in order to be able to read it. Sometimes it is working or else it is still fail to read.I don't know what is the problem but I get this Inaccessible Function error. And when I checked at Disk Management, the file format of the USB flash drive shown as RAW.I have Ubuntu on my PC (dual boot). And it is just working. Therefore for some reason, my Windows 7 is stupid enough to detect my USB file system.

I purchased a Toshiba Lap Top from a lady. She said that she had the system completely restored....she sure did. I have no internal sound and my pen drives will not work in any of the USB ports. What do I have to do to get them to work? I have all of my work on these pen drives.

So recently my desktop PC has been freezing at random times, and then sometimes restarting after not responding for a couple of minutes (no BSOD, just restarts as far as I've seen). It sometime freezes as soon as I turn the computer on, while Windows is loading, and sometimes it will start freezing after an hour it's been on. Most of the time it will just freeze for around a minute, and then unfreeze, but sometimes it does freeze and then restart. By freeze I mean everything, mouse included, and ctrl+alt+delete doesn't work.Also at bootup sometimes, it will fail to detect my SATA hard-drive and hang at Detecting SATA drives at the bios screen. This will be following by a disk read error.This problem started occuring a couple of weeks a go, so I reinstalled Windows 7 and it worked fine after that.
Running Windows 7
Bios: Phoenix - AwardBios v6.00PG

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 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

I have read that using a computer specifically for financial transactions with known and trusted entities (such as a bank) is a good way to reduce (though not eliminate) the risk of your accounts being hacked by reducing the likelihood of inadvertently installing a malware, spyware, or virus by reducing internet sites visited. Assuming this is correct, I was wondering about dual booting one computer with two physical hard drives (each with its own OS) versus one hard drive with two partitions. I figure the former would be "more secure" since one drive would be isolated from any unwanted programs. However, since they shared a few things (motherboard and such), is this set up as "secure" as having two computers? If so, how does one go about setting up a dual boot with two separate hard drives of the same operating system using one computer?

Just new here, i am right now installing my new-built PC with Windows 7 Enterprise.
Unfortunately, i have already some problems. My hard drive is a 1 TB WD and on setup i made a primary partition of 50 GB for Windows 7. I thought to partition the rest afterwards and there is the problem. The installation went without any problem, but in diskmanager i cannot see the option as i saw in XP to choose between a primary or an extended partition.
I wanted to make a large extended partition of the unallocated space and then divide it into some logical drives to hold my programs, pictures & films,... etc. As Windows 7 makes primary partition always i am limited to 4 partitions and that is not enough.

I have had my system up and running with Windows 7 for at least four or five months. I have four drives in an mATX case. Yesterday, while it was idle, I saw it flash a BSOD and then rebooted. when it restated it displayed the following Error: "No active partition found. Reboot your computer." Which I did several times to no avail. Next, I used the install disk to try to "repair" the partition...seven or ten times, no luck. Also, no drives were listed in the window at repair prompt. So, I pulled all the cables on all the drives but the one containing the system and voilas! here I am writing to you without issue and without three of my drives. I have two other sata drives in addition to my system sata drive. one IDE drive on the system.

I'm about to install windows 7 64bit, onto a new system, with 3 hard drives. One for OS and Data. Second one (SSD) will only be used for caching - fast boot. Third one for -printer-pagefile etc. System is ASUS P8Z77-V deluxe, which has UEFI. Do I need MBR partitions or GPT Partitions.

On my home computer, I have 2 physical drives. One hard drive has a single partition (D:) and the other (newer) drive has two partitions (C: and E:). Unfortunately when I first purchased this computer, the technician mistakenly installed Windows XP onto my older hard drive (D:) rather than installing the OS onto the desired C: drive.
The main problem that I am having is: Can I perform a clean install of Windows 7 onto C: drive even though my current OS (Windows XP) is installed onto D: drive? P.S. I have already backed up all files that exist in all of my partitions and would like to format all of the drives (C, D, and E)
drive spaces: C: = 40gb D: 200gb E: 200g

What's the best type of DVD to use for read-only and read/write applications? I'm a little out-of-date on this, haven't bought any in awhile. I remember things like DVD-R/RW and DVD+RW and such. I have a new machine running Win7, and an older laptop running XP.

I just finished putting together my computer, installed Windows 7 Pro 64 bits. However, both of my hard drives (one SSD, one regular HDD) are showing up as external drives (plug-and-play). If I click the "Safely Remove Hardware" icon, I could actually "eject" both of my hard drives.

TLDR: I get the "A disk read error occurred" error but the system disk is readable and checks OK in the recovery USB. So, I have two hard drives--a terabyte drive with some data on it and a smaller drive with the Windows 7 installation on it--and a USB drive. I made the USB drive into a recovery USB using the instructions here Installing Windows 7 System Recovery into USB Flash Drive | Raymond.CC Blog with the addendum found in the comments. I made a system image of the smaller drive via the control panel and then put the image in the terabyte drive. I then replaced my smaller hard drive with a new drive of a comparable size.In order to restore the drive, I booted into the recovery USB, formatted the new hard drive with ntfs, made it active, and ran wbadmin start recovery -version:xxx -items:C: -itemtype:Volume -backupTarget:C: -recoveryTarget: where C was the terabyte drive and D is the new drive. I may have the drives mixed up here, but I assure you I had them correct when I actually ran the command
After a reset, I got some generic error so I went back into the bios, and set the new drive to be at the top of all boot lists, and then rebooted. It was at this time I got the above error. I feared that my drive was actually DOA, so I booted back into the recovery. I did a D:;dir and saw that all of my old files did indeed exist, so I figure it was a boot issue. I ran the boot repair utility in the recovery menu and it said there were no errors and I should restart. I didn't restart, and instead ran a chkdsk D: /f and found no errors. I did a bootsect /nt60 /all /mbr and restarted and still nothing changed. I even tried a "bcdedit /timeout 10" and I do not see the boot loader before getting this error. Not sure if that is expected or not but I'll throw that in here.

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.

I'm a long-time reader but new poster. I am currently running Windows 7. I want to install Windows XP onto another disc and have a dual-boot setup. I keep Windows 7 up to date and secure, but for the XP partition, I would rather not have antivirus running or even installed, in order to limit background processes. I will not be logging into any place or making any credit card purchases when booted into Windows XP. It will just be used for surfing, games, etc. Further, if and when XP becomes compromised or buggy, I will simply overwrite the partition with a backup image.
If I use Bitlocker to lock down the Windows 7 partition (with the encryption key on a thumb drive) and boot into Windows XP, am I correct in thinking the XP installation see or can't access the Windows 7 partition? If XP gets compromised, can a virus access or write to the Windows 7 partition?
Is there any other reason why this would not be secure? Can a virus write to the BIOS?

I wanted to create a new partition to try out linux. So I decided to shrink E: by 20 GB. I then formatted the free space into a new drive by right clicking and creating new simple volume. I was warned that the drive would be made "simple", but not knowing the implications, I went ahead with the procedure. Now on rebooting, windows won't load. I had made a repair disc, so was able to use it to check for any start up errors. It reported none. Moreover I used "diskpart" through cmd to find volume c: is dynamic.

I'm using Compaq Presario CQ40-627TUMy Laptop SpecIntel Dual Core Processor T4400 (2.2GHz, 80Mhz FSB,1 MB L2 Cache)- 2048MB 800MHz DDR2 Memory- 320GB 7200rpm Hard Disk Drive- 14.1' TFT WXGA High-Definition widescreen LCD panel with brightviewtechnologynd i'm using windows 7 Ultimate on boot system partition C, dual boot with linux mint. which mean i got four partition. one for linux mint. one for its swap space. one for windows 7. one for my data storage(movies,drivers,mp3,picture and etc).last few days i try to resize my C partition (120gb) to make it smaller to gain some unallocated spaces and resize the D partition because my D (almost 100gb) (ntfs/primary/data storage) almost full. i use easeus partition master v5.01.
After done resizing and restart i can't see any D partition. so i was worried that my data will disappeared. i try to look for it but there is no Drive D even on the easeus or diskpart. the only drive appears was C Drive.i remove my Linux Mint and its swap (60gb) and thinking that i could get some more free space and do some cmd prompt windows 7 repair fixmbr thing to remove the grub. then i use partition recovery to transfer those missing data from partition D to C Drive. (appears as unformatted)i try to use partition wizard home to resize it back to 300gb. and it works. but i cant make a partition. it will disappear just like that.i also try to use diskpart,command prompt diskpard, and paragon. but also not working. the C drive was shrink but theres no unallocated space and no D drive (the new create partition). i try logical partition,primary,ntfs and fat but also not working. even the unallocated space also gone. i use almost 4 3rd party partitioning software but still got no luck with it.example:i divide 300gb into 2 partition which exist the C partition 150Gb but the other one gone. i wish theres other way than format. i also done many time. doing check disk, partition table doctor, searching for bad sector. but no errors with my hdd.

I have Windows 7 ultimate 64-bit installed on DELL desktop (Optiplex 990) i7 Core. I have two HDD: Disk 0 contains the operating system 500GB. and Disk 1 empty 1TB.
I want to make a partition on disk 1 to mirror the operating system partition and keep the remaining for data storage. I tried to do but I had the following error message: "All disks holding extents for a given volume must have the same sector size, and the sector size must be valid."
I tried to attach a screen shot but couldn't.
