This is just for info, i think there's a problem with the OKR and the recovery software for all s10 or s10e. According to Lenovo this drive partitioning is a new way of ditching the recovery disc that they provide to their laptops to lessen their responsibility on warranty and tech support. As for the HD partition i advice all s10 & s10e owners to refrain from messing around with the partitions until Lenovo comes up with a solution to this problem. If you attempt to repartition your HDD the OKR will lose its functionality.
On my s10e 160GB HDD 2.5gb D:\SERVICE002 hidden fat32 for its recovery files, the rest is C: formated as NTFS. If you want to know the partitions for your HDD the best way to do this is through windows administrative tools-disk management.
Now here's a tip for you s10 & s10e users, i suggest you reformat your HDD and repartition it to your liking and reinstall all the drivers by downloading it from Lenovo website. after installing everything, install OKR software also from Lenovo site and recreate your your backup image files that way it will be a more smaller backup, coz the factory backup of s10 & s10e includes all the trial softwares will bloats the factory image files. but before doing so first backup the factory image files from your recovery drive and store it in a safe place incase you might need it in the future.
Anyways if your really upto tinkering with your newfound gadget then go for it. but if you think you'd rather stick to the factory settings of Lenovo then i'd rather you maintain whatever comes with it & don't use any third party utility software that might interfere with the recovery files.
Enjoy your new s10 & s10e.
P.S. upgrade your memory to get the best satisfaction for your s10 & s10e.
