Due to a HDD failure, I had to reinstall ESXi but now it doesn't recognize the old datastores.
Is there any way we can recover the old datastores on separate scsi disks on the same server.
You will need to provide more information.... does not recognize the old datastore?

The disks show up in the Add Storage dialogue box but it says "UNable to read partition information from the disk" while trying to add the datastore...
Try a rescan from the service console: vmkfstools -s vmhba#
or esxcfg-rescan vmhba#
if the disk is already formatted in VMFS you should be able to see it without adding a new disk, adding a new disk means formating.. I assume you just want to get access to the disk, therefore try rescan tools

Also the old VM's were in ESXi 3.5 update 2 where as the new system installed is exsi 3.5 update 3.
the update 3 will not change anything regarding your datastores, try the rescans and let me know the results

tried it several times, even tried swapping the disk with another ESXi 3.5 update 2 even that did not recognize it.
It is not working with any of the 10 disks in the system so It can't be the disks and since each disk was a separate datastore, so it can't be anything related to partitions.
could you provide some info about the disks that you are using and the controller

The system is a Dell PowerEdge 6600, the disks are hot swappable iSCSI disks.
