Corrupt D Drive

kleer51 · 08-14-2009, 02:08 AM

I have installed a new larger hard drive on my ACER laptop. I used Acronis True image Home to restore a backup of the C drive. There is also a D drive which was put there by ACER and not used by me. I now get a message for the D drive that says "file or directory is corrupt or unreadable". How can I safely remove the drive (it shows as a separate partition) and reallocate the space?

I am happy to try command line commands if that's how to do it.

Hello and welcome to TSF, kleer51!

Is D: occupied?

kleer51 · 08-14-2009, 04:56 AM

I'm not sure that I understand the question. Acronis says it is taking up 45GB of space. Explorere shows it as a drive, but refuses to open the D: drive. There were files in that drive last time I looked at it, which is months ago.

TJ Belfiore · 08-14-2009, 05:01 AM

I was just asking if your D: drive is being occupied by any files, folders, etc. Basically, I was checking to see if there was important data on it or not.

P-P-P-Please refer to this thread, as it's very fimilar to this thread.

Is your HDD NTFS?

Have you tried another USB port?

How old is this HDD?

Windy

I appreciate the help.

Have looked at the referred thread, but not seeing much in common. Let me be clear - this is not an external HDD. It is now my internal HDD, and C: has the OS which seems to be working fine.

Acronis sees this partition as 44.9GB NTFS. Sector size 512, 8 sectors per cluster, sectors per track 63, Media ID 0F8h, Sector 267,321,600. Could I just format drive D: from CMD?

Formatting would erase all your data . . .

kleer51 · 08-14-2009, 05:40 AM

All my personal data is on a different partition (drive:M) and backed up, so it would not worry me to lose the data. Maybe ACER might have had backups of all the OME software on that partition but I never had occasion to use it, and the laptop is two years old.

Can you just remind me the exact syntax for the format?

TJ Belfiore · 08-14-2009, 05:42 AM

Sure.

FORMAT D:

D: being your drive letter.

If you want to delete the drive type computer in the search area of the start menu then select computer management from the list at the top. In computer mahagement select disk management. Then right click on the partition and select deiete volume. It will then be unallcated space. You can extend the c partition to claim the unallocated space. Right click on the c partition and select extend volume.

You can do it UW's way but you will have an empty partition. You did ask to remove the partition. Did you not?

kleer51 · 08-14-2009, 07:41 AM

pofolks...thanks, that sounded really good. Vista has slightly different path to Disk management but I found it. When I did find it, I saw four volumes, thus
1. Blank (i.e. no name on volume) - Simple Layout - Basic Type - File System (empty) - Status Healthy (EISA Configuration)
2. Volume D: (the one I wanted to delete) - Simple Layout - Basic Type - RAW File System - Status Healthy (Primary Partition)
3. Volume C: (which has my Vista OS) - Simple Layout - Basic Type - NTFS File System - Status Healthy (System, Boot, Page File, Active, Crash Dump, Primary Partition)
4. Volume M: (which has my personal data) - Simple Layout - Basic Type - NTFS File System - Status Healthy (Logical Drive)

Is it OK to delete the D:drive (which incidentally says 100% free space) even though it is a primary partition?

I'm OK with it to become unallocated, just checking before I delete something which you might now say is part of the system (I'm not sure what RAW file system means).

Thanks for all the advice.

A raw file system is a partition that was created but never formatted. Hence the reason why you would get 'directory or file system is corrupt or unreadable' . On new computers the D partition is usually the recovery partitition. As to why it was or was not created is water over the dam. The partition is history and should be deleted. You would have to resotore to factory condition from the recovery disks to get the recovery partition back.

If you want to reclaim the unallocated space for your c(vista partiton), you will have to right click on the c partition and select extend volume from the menu.

kleer51 · 08-14-2009, 09:08 AM

Thanks - I have now deleted drive D: and extended drive C:. It was scarily easy once you had pointed me to disk management. Windy's idea to format the partition might have been good too, so thanks to both of you. I now have a HDD which is just how I wanted it.
