Which operating systems are supported with this drive? |
| A1. |
All major operating systems are supported for reading media. Software support is required for writing to CD and DVD writeable media." For Microsoft® operating systems, this is available by using Roxio Easy Media Creator. For other operating systems, an operating system-specific software utility is required for writing to media.

| Q3. |
Should I buy the DVD-ROM or the DVD RW drive? |
| A3. |
If you are concerned about data security in your environment, you should buy the DVD-ROM drive since it's a read-only optical drive. You should buy a RW drive to provide write capabilities.

| Q4. |
Can I play DVD movies or games using my HP DVD drive? |
| A4. |
HP Servers do not include the appropriate hardware or software to allow DVD movies or games to be played.

| |
| Q5. |
Why can't I play movies copied to my hard drive? |

| Q1. |
What is PATA? |
| A1. |
PATA ("Parallel ATA") is a standard interface for connecting storage devices. PATA technology allows 16 bits of data to be transferred at a time. This interface is quite common and relatively inexpensive when compared to the SATA interface which was introduced in 2003. In the optical industry, the PATA technology is being discontinued and replaced with SATA.

| |
| Q2. |
What is SATA? |
| A2. |
SATA ("Serial ATA") is the successor of PATA technology. It's expected to replace the PATA technology eventually. SATA uses low-voltage differential signaling (LVDS) which allows for faster data transfers than the PATA standard. SATA technology uses a direct connection between host and drive with no sharing of cable or bandwidth between devices. The standard interface for SATA controllers is AHCI, which enables advanced features such as hot plug and native command queuing.

| |
| Q3. |
What is the difference between PATA optical drives and SATA drives? What does this mean to me? |
| A3. |
The main advantages of SATA drives over PATA are:
- The SATA drives contain more compact cables that allow air cooling to work more
- SATA technology results in faster data transfers
- The SATA drives have the ability to remove devices while operating (hot swapping)
- SATA drives allow for more reliable operation with tighter data integrity checks
Note that SATA devices are not compatible with PATA devices

What is a dual-layer disc? |
| A4. |
dual-layer disc can hold two layers of data, rather than one, meaning it can hold up to twice as much data.
