Guys, since my recent upgrade to an OCZ Vertex Plus 120GB (oczssd2-1vtxpl120g) SSD, chkdsk is running every other time I boot up.
There seem to be regular file issues too, I've lost key dlls from Avast and had to reinstall it and similar on itunes.
Today, again, the machine is without a working Avast install after the loss of some dlls and I'm worried that the drive is likely faulty.
Can someone recommend the best way of concluding whether there is a hardware fault or not, and if as I expect it is, the easiest way to transfer my relatively new and clean Win 7 OS to another SSD which I'll purchase. I notice there's a firmware upgrade for the drive and I'm tempted to try that, but I'm worried about cock ups basically! I have also wondered if there were issues with my motherboard and it's AHCI abilities, but looking around online there doesn't appear to be much in the way of reported issues with the Asus P5QL mobos.
As part of the SSD transfer I purchased and used Paragon Migrate, which managed to corrupt the install and I had to start again from scratch. A hardware fault might explain that, so I'm interested to see if I can use that same program to transfer to another SSD.
As always, thank you all for your help, this is one of the best technical resources online I've used.
