Partition / drive intermittantly read only

[Woodgnome]

Hi All - this has been driving me mad -

I have a pair of WD 500GB drives in Raid0 array with the resulting >900Gb partitioned such :

C: Priamry 100Gb - Win7 64bit
D: Primary 80 GB - Win7 32bit
E: Primary 40GB - Win7 32bit
R: Secondary Logical - 355GB - Data
Z: Secondary Logical - 355GB - Data

Using DualBootPro to boot between the various OS

Both the win7 32 bit installations give me no problems whatsoever, however, intermitantly when booting into the win7 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 win7 32 installtions, but can occur even after a previous successful boot of the win7 64 installation.

A complete reinstallation of win7 64 into the first partition hasn't resolved the problem

Has anybody experience of this please or a possible solution? - many thanks

Hello.



Perhaps there is an issue with the 3rd party boot manager, have you tried uninstalling it to see if that sorts it? You could make sure the first partition is marked as Active and do the 3 startup repairs with the separate restarts and use the Windows managed dual boot just as easily.

Hi - many thanks for the reply - dualbootpro is only used initially to add / modify the BCD record, so normal os selection during bootup is via the windows boot manager. The problem is experienced only intermittantly and has been observed with only the active partition containing an OS. Windows boots & runs without problems, it occcasionally marks the extended partitions as read only (never the primary partitions) and only the 64bit version, when either of the other 2 32 bit versions are used, the problem never manifests itself. I am reather tempted to bite the bullit & reformat & secure wipe the extened and see what effect that has.
Thanks again for the reply - I have bookmarked yout excellent tutorial for future reference.

Hello again.



After you have copied out or made back-ups of the data you need to save to external media, you could use Option Three in this tutorial at the link below to do a partition-specific wipe (secure erase) to the Extended partition; I'd be curious to know the outcome if you do so.

My apologies, I didn't add it.

Actually you could do the Locical drives separatly, you'll see what I mean.
