Hi folks
I don’t know how this problem occured, but here goes:
I have installed Win7 on to my NC10 and also replaced the XP backup with Win 7. It has been fine since November.
Yesterday I checked the file partitions and I the 100mb hidden patition that is used to recover windows has some how been made visible and is drive d, with my data patition now being drive E (windows is still C).
I rebooted and went into the recovery software and access the admin section (p/w secos) and checked the hard disk. It has the 100mb partition as drive C, my windows partition as drive D and my data partition as drive E.
No matter what I do I cant get the 100mb partition to stay invisible. Does anyone have a clue??
Cheers

If you go to Administrator Tools in the control panel (search for admin), then go to computer management then Disk Management (may be named differently). You should be able to right click on the 100mb partition and go to drive letter assignment, then remove the drive letter.
February 21, 2010 at 1:47 pm #210950StriderMemberThanks for the reply Alfihar:)
I tried what you stated but to no avail.
I looked around on various forums and the over-riding consensus was that if you don’t use Bitlocker or are not looking to dual boot then removing the 100mb partition is safe.
So I logged in to the Recovery admin section and made a bootable recovery USB stick, logged on and reset all of the partitions, removing the 100mb one.
I then simply reinstalled Win7 Pro, which did not create a new partition and low and behold it is business as usual.
Now all is fine:)
Cheers

Another way of achieving the hiding of the partition would either be with Eausus or using Diskpart.
select disk 0
list partition
select partition 1 (number identified by list partition)
remove letter=D (drive letter assigned to 100MB partition)
set id=27 override (to hide the partition)Hope this helps someone with a similar problem
February 22, 2010 at 8:12 am #210951StriderMemberHI jeepers
thanks for the tip. I fully reinstalled windows and did what you suggested and everything seems okay, but when i go to the admin section of the recovery software and select hard drive it now has a question mark next to the 100mb partition. Will it still work okay without a letter assign as z has been assigned to the recovery partition.. ???
To be precise it has:
z: 6GB Recovery Partition
?: 100mb partition
c: 43gb Windows Partition
d: 100gb data partitionCan you check to see if you have one on yours??
Cheers

February 22, 2010 at 9:28 pm #210954jeepers01ParticipantStrider – To remove the drive letter (Z) and hide the Recovery partition try as follows:
diskpart
select disk 0
list partition
select partition 1 (number of the Recovery partition identified by list partition)
remove letter=Z (drive letter assigned to Recovery partition)
detail partition (Will show partition type as 07 ie. unhidden)
set id=27 override (to hide the partition)
detail partition (should show partition type as 27)see example screen below:
You can also check the Windows 100MB partition
diskpart
select disk 0
list partition
select partition 1 (number of the Windows partition identified by list partition)
detail partitionSee what partition type number it returns. If it is 07 then you could proceed as above to hide it, but it depends on the number it returns. Perhaps you could post the results from detail partition.
That said if Windows is running well there may be no point in disturbing it and the question mark may be normal for the software you are using to check it. Are you using SRSIII or 4?
I don’t have the 100MB partition on my dual boot XP/Win 7HP install so I can’t check this first hand.
Hope this helps
February 22, 2010 at 10:23 pm #210952StriderMemberThanks again for your detailed reply. Oddly before I hid the 100mb partition it showed it as being a system partition and when i used the set id commands it changed it to an OEM recovery partition.
BTW I am using SRSIII upgrade – i loaded srs4 onto my sammy and on parts of the program it states srs4 and on others srslll
The SRSlll admin harddisk view states that the recovery partition is Z, but doesn’t show in Windows. Oddly my volume for the recovery partition is 2 whereas yours is 0, why is that.
Cheers

February 22, 2010 at 10:32 pm #210947AlfiharParticipantSetid is used to change the partition type. And should affect any OS that attempts to read it. Setting it to the wrong type could stop it from working especially as diskpart doesn’t check that the type is valid.
Whereas when you hide the partition (remove the drive letter) you are just stopping Windows from assigning it a drive letter (it might also not mount it, I’m not sure). This is OS specific hence why two copies of Windows installed on a computer can have the drive letters assigned differently.

Thanks again for your detailed reply. Oddly before I hid the 100mb partition it showed it as being a system partition and when i used the set id commands it changed it to an OEM recovery partition.[/quote1266879067]Your welcomeWhat was the partition number of the 100MB partition before it was changed? Assuming it is now 27.
I was rather hoping you would have posted the results from detail partition. Was this 07?
If you have forgotten no doubt Alfihar can provide this information.Quote:BTW I am using SRSIII upgrade – i loaded srs4 onto my sammy and on parts of the program it states srs4 and on others srslllYes it’s odd the way it does that. On mine it even mentions ‘Upgrade’ 🙂
Quote:The SRSlll admin harddisk view states that the recovery partition is Z, but doesn’t show in Windows.In ‘detail partition’ is the partition shown as Hidden with no drive letter assigned?
Quote:Oddly my volume for the recovery partition is 2 whereas yours is 0, why is that.The volume table will be different to my machine since i do not have the 100MB partition.
You can check the volume table with the diskpart command ‘list volume’Hope this helps

The 100MB partition should be of type 07.February 22, 2010 at 11:14 pm #210956jeepers01Participant[quote1266880217=Alfihar]

The 100MB partition should be of type 07.
[/quote1266880217]Thanks for the info.That indicates your 100MB partition running unhidden?
February 22, 2010 at 11:24 pm #210949AlfiharParticipant[quote1266880775=jeepers01]That indicates your 100MB partition running unhidden?[/quote1266880775]
That’s with the default setup, where the partition is unhidden but does not have a drive letter and so doesn’t appear in My Computer/Explorer etc… Assigning a drive letter doesn’t affect the partitions id, which I have just tried and checked.I don’t think the id type of the partition should be modified even if you set the hidden attribute on the partition. Though I’m not sure on the effect on Windows of setting the hidden attribute, and I’m not going to try at the moment as I need the partition to work for booting as I have encryption enabled. 😀
February 23, 2010 at 8:53 pm #210957jeepers01ParticipantAlfihar – yes, the partition type is completely independent and is not associated whether a drive letter is assigned or not as the case may be.
The partition type determines the mode of operation for the partition and how it reports itself to the OS. I’m not aware of any hidden attributes as these are normally associated with the filing system.
So we have established that the 100MB partition is normally a type 7 so it would be best for Strider to re-set the partition type to 07 after removing any assigned drive letter.
This should enable normal operation of the windows partition and it may just be that SRSIII is unable to resolve correctly the partition type and it may be an inherent problem with the Samsung software.
