Yeah, most people aren't convinced until something fails catastrophically. Make sure your backups are good.
Also, it isn't necessarily the physical drive. Could be the firmware, drives, switch, cache, any filter...

Would you recommend migrating the databases on this disk to a different drive?
Well, ask yourself, would you leave important information on a drive that's giving repeated problems?

Drop the indexes 'IX_Advertise_BrandCopy_Price_Stock' and 'IX_ITEMS_ADVFLAG_PARETN_PRICE_STOCK' (on the table 'Items') and recreate them. Don't rebuild them, drop and recreate.

In short it just doesn't use parameter sniffing to estimate the rows that will be affected by the specific parameter values.
