Unable to create new "visible" partition

I have just purchased an Acer Aspire 8935g laptop, which comes wit
Windows Vista Home Premium 32bit (not sure why 64bit isn't supplied). I
has two 500gb hard drives; Disk 0 and Disk 1. Disk 1 is empty and I hav
successfully created 3 partions on this drive. According to Vista's Dis
Management tool, Disk 0 contains three partitions. The first and las
are both EISA Configuration partitions and can't be seen through Window
Explorer. The 2nd (middle) partition is the C: partition on which Vist
is installed

I want to install Windows 7 RC 64bit in a dual boot configuration, so
used Disk Manager to shrink the C: partition and then create a new 100g
partition. I assigned it the drive letter B: (there are no floppy drive
on the laptop). The new B: partition is visible, along with the origina
C: partition through Windows Explorer, until I reboot the laptop. The B
partition then disappears and Windows Explorer can no longer see it
however Disk Management shows it is still there but it no longer has
drive letter and is now an EISA Configuration partition. I thought thi
issue might be caused by the choice of drive letter so I tried agai
using a different letter (F. Each time the drive is only visible t
Windows Explorer until the laptop is rebooted. I've also tried using
different partition management tool (Partition Wizard) but it makes n
difference. I've tried creating the partition as logical and primary bu
to no avail

Can someone please explain what is happening? Why can't I create
visible partition on my "O/S" drive

Hi, Milleniumaire.

I'm not sure it would make a difference, but did you format your new
partition before you rebooted?

I've never had a laptop of any kind, and haven't bought a new computer in 20
years - I just buy the components and build my own - so I have no idea about
an EISA configuration partition, except what I read in these newsgroups.
But I would expect only a single EISA partition, for the OS recovery files.
How did you get two on your Disk 0? Did Acer explain that?

It sounds to me like you did everything right, so I hope some Acer guru can
explain this to both of us.

Hi RC

I did format the new partition before rebooting. After shrinking th
original C: partition and making space available for the new partitio
it was necessary to format it before I could create the new partitio
(or was it after I created the new partition). Either way it ha
definately been formatted

I've been looking for a good Acer forum that might be monitored by Ace
gurus, as I suspect your right and this is likely to be an Acer specifi
issue

I contacted Acer who tell me they don't support the creation of
partitons on the main O/S drive as this will affect their recovery
software! They went on to say that if I do change the way the recovery
software works it would void the warranty!!!!

I'm absoluteley amazed. I have a state of the art laptop with 2 x 500gb
disk drives. I can partition one of them, but not the one with the O/S
as this will void the warranty.

Hi, Milleniumaire.

BUMMER! :>(

Many users (and even Microsoft) disagree over the question of whether
multiple partitions are better than a single one. I think it varies
depending on how YOU want to use YOUR computer. I'm not sure I would ever
buy a computer from a vendor that saddled me with a policy like you
describe!

My typical configuration - dating back a decade or so to when I began
dual-booting Win95/NT4 - is to create a single primary partition on EACH HDD
(I currently have 4, two of which are a RAID 1 mirror) and mark it Active.
Then I install Windows at least once with each HDD set in the BIOS as the
current boot device, so that Setup creates the proper MBR, boot sector and
startup files on that HDD. That way, I can always boot from Disk 2 if Disk
0 is damaged or missing. After creating the one (small) primary partition,
I create an Extended Partition covering the rest of the HDD and divide it up
into multiple logical drives as I need them. My 200 GB Disk 0 has 3 logical
drives, plus 15 GB of Free space. (I don't need the pre-beta build of Win7
anymore, so when Win7 RTM arrives from MSDN next week, I'll just delete or
reformat Drive Y: - the 6th logical drive on Disk 1 - and use that 60 GB to
install RTM. WinXP/Vista/7 doesn't care whether it is in Drive C: or D: or
X:, and I've also learned to not care about that. About half of my 1 TB
Disk 1 is still unused, but I'm running out of alphabet for Drive letters.)

Thanks for the report back about Acer's short-sighted policy.

HI, again, Milleniumaire.

I just saw an earlier thread in this NG, Subject: Preferred Install of
Vista x64 Ultimate, in which Noel Paton, a former MVP, reported in a post
dated 5/2/09 that his Acer 8930 had 4 partitions:

> 2 are visible (C: and D

Still seems very strange to me!

Use something other than B for the drive. B is associated with a removable
drive.

Hi, Duck.

Can you cite some authority for that assertion?
