Whatever you do, avoid Mushkin/Sandforce 2nd-gen drives.
I have been having nothing but trouble with my Chronos Deluxe 240GB model.
I thought it was hosed completely, since Windows 7 wouldn't even install to the drive.
But I plugged it into my HDD dock on my Rosewill Blackhawk (connected to a SATA2 port on my P35 mobo), and it was recognized.
I was able to go into Disk Management, delete the partition, re-create the partition, and do a full format. It made it more than halfway through, and then it stopped incrementing the percentage, and then the drive simply disappeared. Out of Device Manager too.
Whoever said you could "reset" 2nd-gen SandForce drives by doing a secure erase, was wrong. This all happened AFTER a supposedly successful secure erase procedure. The drive indicates (in Linux) that it does not support "Enhanced" Secure Erase. And the Normal Secure Erase completes so quickly, I cannot believe that it is purging flash pages.
