Vista Reload at Boot & IaStor

[ChuckR]

My wife's HP A6120n machine with Vista Home, suddenly required Vista to reload files to boot. It does not happen every time, only twice in the last week. She is unhappy. I went through the event logs and found an error or Iastor, so I did a search and found 43 entries. IaStor, IastorV, Files and folders spread mostly in Drivestore folder. HP has a D: for backup which I do not know if it is RAID. How can I identify it? Should there be so many entries for IaStor?
Has anyone else had this issue?
Thanks

storage driver event log entries can indicate a failing HD. Use bootable mfg diagnostics to check the HD.

What about chkdsk? Any other suggestions. Money is a problem for a one time purchase.

Iastore, is the driver name for the Intel ACHI/Raid controller. could be indicating a hard drive problem.

I would run the drive maker's software first and if that passed then run chkdsk

Otherwise just bite the bullet, and by a cheap hard drive and replace it, restore it off the recovery dvds that you made, or if you have not make them now.
